The summer months are the perfect time to get outside and enjoy everything nature has to offer, but while you’re having fun in the sun, weeds are too; stealing your landscape’s resources and getting stronger every day. Thankfully, with proper identification and action, you can get rid of these intruders and take back your landscape. Here’s a list of the most common weeds you’ll find in Roanoke during the summer.
1) Lespedeza is a summer annual legume that you’ll see sprinkled throughout your lawn and competing for resources. They are prevalent in high-trafficked and poorly drained areas of your turf. If lespedeza is appearing in your lawn year after year, we recommend being proactive and applying a pre-emergent herbicide. We use Dimension. If common lespedeza is already established in your lawn, you can use a post-emergent herbicide such as Escalade, but multiple applications will be necessary. To learn more about lespedeza click the link here.
2) Spurge resembles lespedeza and is another summer annual that you’ll see in weak areas of your turf and also throughout the cracks of driveways and hardscapes. This low-growing, fast spreading weed thrives in sunny spots with well-drained soil. If not treated, it can quickly take over your landscape. If you remove young spurge early in the season and apply a pre-emergent herbicide, you can stop the spreading. Otherwise, your landscape will need frequent applications of a post-emergent. Check out the link here to learn more about spurge.
3) Violets are beautiful flowers, don’t get me wrong, but wild violets are among some of the most difficult lawn weeds to control. They spread through rhizomes underground, so pulling them out of the ground can be tedious and ineffective; as the rhizomes tend to break off and regenerate. They love parts of your turf that are shaded, parts that remain wet for extended periods of time, and places where grass doesn’t usually grow. One way to get rid of violets is by trimming overhead tree branches to allow sunlight to shaded areas. Learn more about violets here.
4) Finding a four-leaf clover is considered lucky.. if it’s in someone else’s landscape. Clover is another weed that likes to compete with your turf’s resources. Although clover is considered a weed, it can be semi-beneficial to your lawn; as it pulls nitrogen from the air and distributes it to the soil beneath. However, it will quickly take over your entire lawn if left alone. Spraying a mild post-emergent on concentrated areas of clover and keeping a dense, thick turf should eliminate it from your yard. Find more information on clover here.
5) Broadleaf Plantain was once coveted for its medicinal implications, but now it’s one of the most common weeds you will find. The reason it’s among the most common is because of its tolerance; it can survive in harsh environments, poor soils and in extreme temperatures. Because of its resilience, broadleaf plantain is hard to control. Using a broadleaf herbicide proves effective after several treatments, but we recommend aerating your lawn; especially in compacted areas where plantain like to grow. The best time to aerate your lawn is early in the fall, which allows your landscape a little time to recover from the stresses of summer. Click here to find out more about broadleaf plantain.
6) Nutsedge isn’t like many broadleaf weeds targeted by herbicides, it’s a perennial species of sedge that will grow back in your yard every year. It’s referred to as “nutgrass” because of its resemblance to grass, but can be distinguished by its triangular, v-shaped stems. It can be hard to spot the difference at first glance, but upon closer examination of the stems you’ll see that “sedges have edges”, while grass stems are circular. Nutsedge doesn’t do well in the shade, so try planting taller ground-cover plants or shrubs to shade the weed out. There’s more on nutsedge here.
Mulch and plants go together like peanut butter and jelly, and honestly no spring landscape is complete without it. Not only is mulch aesthetically pleasing, it helps to insulate plants, suppress weeds, retain water, and so much more! If you haven’t been adding mulch to your landscape then you’ve really been missing out. Check out the many benefits of mulch below!
The main benefit of adding new mulch to your beds is to suppress unwanted weeds. If sun can get to bare dirt, then weeds will germinate. Mulch acts as a protective layer between the sun and the dirt, preventing unwanted weeds from getting the sunlight they need to grow. A pre-emergent should be sprayed before the mulch is added, as an extra layer of protection. In some cases landscaping fabric is added under the mulch as well, especially when using stone mulch or in areas prone to erosion. The landscaping fabric creates yet another barrier between the sun and the soil.
Mulch absorbs and retains water, making it essential for poorly drained areas or flower beds on a steep grade. Mulch also acts as an insulator, keeping the heat in and preventing an unexpected frost from damaging your plants. It regulates the temperature of the soil and helps reduce any significant swings that could injure your plant’s roots. Mulch is organic matter, so as it breaks down over time it will improve the soil below. It also helps keep the soil chemically balanced, by retaining several key nutrients such as magnesium, calcium, phosphorus and potassium.
Sometimes mulch is used in shaded or damaged areas where grass just won’t grow. Creating mulch beds is a surefire way to remedy a damaged landscape, but it’s also an opportunity to be creative and make your landscape truly one-of-a-kind. It’s a way to display plants and establish areas of interest throughout your landscape. A unique landscape, paired with various larger plants, adds curb appeal to your home and drives up its perceived value by up to 15%. You can read more about that here. Mulch beds and defined spaces also make your landscape easier to mow and maintain.
When adding fresh mulch to your beds, more mulch is not always better; 2” is about all you need. Adding too much mulch, such as creating a mound around a tree, creates a space for insects to hide; creating the potential for insect infestation and related disease. Furthermore, landscape fabrics will help reduce weed seed growth, but organic matter will inevitably get between the mulch and the fabric; causing weeds to sprout. Simply put, there’s no such thing as a maintenance-free mulch. At some point, weeds will be in your beds and need to be pulled and/or sprayed.
Water is an essential building block to all life on Earth, and plants are no exception. Thorough watering is absolutely critical to establishing healthy root systems; especially in areas experiencing drought or subjected to limited rainfall. Water not only provides hydration, but also acts as a vehicle for other nutrients. It breaks down nutrients, such as those found in fertilizer, making them more efficient and easier for the plant to consume. Without water seeds cannot germinate or survive. If your plants have nothing else, make sure they’re getting some quality H2O.
Just like humans, water makes up a significant portion of a plant; it’s a source of strength. A plant deprived of water will wilt or droop, but a well-watered plant will maintain its shape. Most plants get their water from the soil, so it’s important to establish a healthy nutrient-rich soil as well. Having an adequate water supply is paramount to a plants growth, but too much water, however, can have the opposite effect; plants essentially drown in the excess. Concerned that your soil may be too wet or too dry? Use the finger test. Stick your finger into the soil; if soil sticks to your finger it’s just right, if not then water thoroughly and check back in a few days.
It’s fairly easy for your plants to receive too much water, and in some cases it’s unavoidable. Heavy rainfall can waterlog entire communities and make it very difficult for plants to survive. Fortunately, there are ways to improve and condition your soil for a wet (or dry) climate, by changing its composition. Sandy soils have large pores and tend to drain very fast; creating a dry environment for plants. Clay soils have very tiny pores; trapping water and not allowing it to drain, or blocking water from reaching the roots at all. In both cases, incorporating organic matter into the soil (such as compost), is a viable solution. The organic matter adds nutrients and helps to balance soil density.
Check out this cool video from New Frontiers below to learn more about watering your plants. There’s also a great demonstration that shows how much water roots will actually absorb. Spoiler Alert: It’s a lot!!!
Trees are among the most essential plants on the planets and come in a variety of shapes and sizes. A non-taxonomic species, trees are often categorized as any plant with an elongated trunk and secondary growth, or plants that can be harvested for lumber. In some cases, plants independently form a “trunk” as a means of survival; successfully beating out nearby plants for sunlight and other resources. Trees play a significant role in moderating our climate; by removing carbon dioxide from the atmosphere and storing large quantities of carbon in their tissue. Their root systems help control erosion and their branches provide shelter and shade for a plethora of life-forms (including us). We make paper, homes, and everything in between from trees; without them our world would be vastly different or possibly even non-existent.
In our last blog post we discussed the oldest trees, Bristlecone Pines, which live for thousands of years. This time around, we’re asking a different question about trees; which ones are the tallest? We’re highlighting the 3 tallest trees on Earth, starting with the Douglas-fir. Watch the video below to check out the complete top 10 list from Trend Max:
3) Douglas Fir (Pseudotsuga menziesii)
A member of the pine family, the Douglas-fir is native to western North America. It’s named after Scottish botanist, David Douglas, who first discovered this towering species of tree in the early 19th century. Its name is somewhat misleading, as it’s not actually a true “fir” tree (as it isn’t a member of the genus Abies). This is why a hyphen is often included in its name. It’s important to note that only Douglas-fir trees on the coast can reach such incredible heights, because of the increased elevation and moisture levels. Those grown elsewhere will only reach a fraction of the height. After 100 years its bark becomes so thick it can resist the flames from forest fires. In fact, the Douglas-fir needs fire in order to reproduce. Native Americans and Hawaiians have used these big trees for centuries as a means to create shelter and to make canoes. The only wooden ships still used by the United States Navy are called “minesweepers” and made exclusively from the trunks of Douglas-fir trees.
2) Swamp Gum (Eucalyptus regnans)
The Swamp Gum may be the second tallest tree in the world, but it boasts another accolade; it’s the highest flowering plant in the world. Its recognizable straight and grayish trunk with smooth bark creates a menacingly tall canopy, however the first 15 meters of the bark is quite the opposite; dark brown and coarse. The Swamp Gum grows in wet forests, in places receiving 45” of rainfall per year, and often has a rain-forest understory of small shade-tolerant plants. Logged for centuries, these trees once reached even greater heights, with some recorded in Australia standing over 425 feet tall. If not destroyed for logging, these trees are often victims of forest fires, although they regenerate by seed. The Swamp Gum produces white flowers in the fall months.
1) Coast Redwood (Sequoia sempervirens)
The Coast Redwood is the only living species of the genus Sequoia, in the cypress family. It’s the tallest tree on Earth, reaching heights of over 375 feet. Some of the larger Redwoods are over 30 feet in diameter. They are found on a narrow strip of land on the west coast of the United States, an area around 500 miles in length and less than 50 miles in width. Before extensive logging, these behemoths used to occupy over 2 million acres along the California and Oregon coast.
I was catching up with some friends the other day when we stumbled upon the topic of the oldest living things on the planet. Sure, there are microorganisms and bacteria said to be millions of years old, but we wanted to know what animals lived the longest, what plants, etc. It turns out there are a lot of ocean critters with long lifespans; sponges that live to be around 10,000 years, coral that are thousands of years old. There’s even a jellyfish said to be immortal (learn more about that here). It was all pretty interesting stuff, but we wanted to know more about plant-life, more specifically trees. I knew the redwood trees in California were around a thousand years old, but that’s nothing compared to the Bristlecone Pine.
Bristlecone Pine is an umbrella term for three different species of pine and all three are among the longest living organisms on the planet; with the “Pinus longaeva” species living to be a whopping 4,000 to 5,000 years old. These species thrive in the harshest of conditions, growing mainly in high altitude regions in the western United States where poor rocky soil is the norm and rainfall is a rarity. In fact, in favorable conditions the Bristlecone pine will succumb to root rot and quickly die out. It seems these trees only tend to grow in arid climates where other plants have no chance of survival; and they tend to grow for thousands of years. They are a first-succession species, meaning they like to be the first to occupy open ground.
Because of all of these harsh living conditions, the Bristlecone grow extremely slow. So slow that the pine needles (in bundles of 5) can remain on the tree for upwards of 40 years. The trick to their survival is in their roots and the ”unfavorable” soil in which they live. Unlike most plants, the Bristlecone prefers dolomitic soil; alkaline, high in calcium and magnesium and low in phosphorus. Its root system is mainly composed of heavily branched shallow roots, while a few larger roots are formed for structural support. Their shallow roots and waxy needles make Bristlecones experts in water retention; a necessary skill-set for the trees survival. Their wood is extremely dense and filled with resin, making them practically resistant to insects, fungi and disease.
If you cut open a normal tree you will see its growth rings, with each ring representing one year of growth. But for the slow-growing Bristlecone, these tree rings are merely just a reference. The trees grow so slowly that rings don’t form every year, adding to the allure of the tree’s longevity. The oldest known Bristlecone boasts over 5,000 rings, with leading experts claiming that the tree could be up to nearly twice that in age. It’s actually still alive and well in the White Mountains of California and is the oldest known living tree on Earth. Check out the video below by Atlas Obscura for more information on the Bristlecone Pine:
Located in northeast India, the state of Meghalaya contains two towns with the highest annual rainfall on the planet. No other place on Earth sees precipitation like these two towns and they’re located just miles apart. Just how much rainfall you ask? Try over 460 inches on average. ON AVERAGE. That’s almost 40 feet of rain in a single year, and that’s an “average” year. A more extreme year, such as 1985, produced more than double the average. That’s right, over 80 feet of rain in a single year; over 1000 inches. For comparison, Roanoke receives a little over 3 feet of rain per year, a national average for cities in the United States. It’s mind-boggling to think people could live or even survive in those conditions. But, in these towns, adversity fuels creativity.
As you can imagine, getting around in the constant rain is challenging (or at the very least an annoying inconvenience). Indians native to the region never leave the house without an umbrella in tow. They’ve padded the roofs of their homes to try and dampen the sound of the rain. They’ve created special hats that keep them dry when they tend to their crops, and shoes that provide better traction over the muddy terrain. But no invention is quite as innovative as their bridges. That’s because these bridges aren’t made from reinforced titanium steel or poured concrete. No, these bridges are alive and they attract tens of thousands of tourists every year.
Flooding is a major problem in the area (imagine that), and the rising water levels create raging rivers that are impossible to cross. Entire villages would become isolated without bridges, making them essential to the native’s survival. Man-made structures can’t withstand the constant barrage of rain and often fail within a few years. So what does a bridge-dependent community do when they can’t build reliable bridges? They grow them.
The living bridges of Meghalaya are created by manipulating the roots of trees over several decades, eventually creating a rock-solid path capable of holding upwards of 35 people at a time. It’s a slow process, but one that “grows” stronger over time with some of the strongest bridges well over 100 years old. The Indians use the Indian rubber fig tree, Ficus Elastica, because its aerated roots can be tied and twisted across bodies of water. The Ficus Elastica is geographically versatile, as it can grow in steep terrain along the banks or even in the middle of a river. Traditionally, the Indians have used bamboo or betel nut trunks that are placed across the channel and used as a makeshift guide for the roots. The guides have to be frequently replaced (especially during the fall’s monsoon season) due to rot from all the rain.
It’s a fascinating technique; and one that the indigenous people are dependent on for survival. As man-made materials become stronger, more affordable and more susceptible to withstanding the elements, the living bridges of Meghalaya are becoming less and less of a commodity. However, the art form still exists and bridges are still being grown to this day. The most famous of the living bridges, the double-decker bridge in Cheerapunji (pictured above), is gearing up for a third-tier expected to be grown in the next 15 years. No one knows when the first bridges were formed, but hopefully the locals will continue this innovative tradition for many generations to come. Check out a short video on the bridges below.
Planting trees in your landscape increases your property value, lowers cooling costs and even cleans the air around you. They also provide a habitat for migrating birds and other pollinators. Do you already have trees in your landscape? Want to find out how they benefit you? It’s all in this week’s blog post. Check it out!
Increased Property Value
Money doesn’t grow on trees, but they do add value to your property. A fully mature tree is usually appraised anywhere from $1,000 to $10,000, depending on the type of tree, health of the tree and location. Researchers at Michigan University found that if healthy trees were part of a well-designed well-maintained landscape they could increase the home’s value by up to 11 percent. Furthermore, just having a mature tree in your front yard will increase your home’s sales price by around $7,000. Considering it takes an average of 30 years for a tree to fully mature, we suggest you start planting them now.
Already have trees in your landscape? Quantify their benefits by using i-Tree, a free tool created by USDA Forest Service Research and used all over the world. Simply fill out information about your tree (species, diameter, distance from house, sun exposure, etc.) and i-Tree will calculate your estimated total yearly benefits. It also calculates how much air pollution each tree filters in a year and the amount of stormwater runoff avoided. Click here or enter “mytree.itreetools.org” in your browser to get started.
Cooling & Energy Savings
Not only do we need shade in the summer, but our homes need it as well. Trees absorb water through their roots and evaporate it through their pores, a process which has a cooling effect on the surrounding air; lowering summer temperatures by up to 9 degrees. Trees block sun from windows, exterior walls, A/C units and roofs; greatly reducing the overall temperature of your home. In fact, shaded walls can be nearly 45 degrees cooler than those exposed to full sunlight.
i-Tree will calculate your yearly electricity savings based on the number of trees and how many you have shading your home. Not only does planting trees near your home have a cooling effect, they also give you privacy from streets and neighbors and provide a noise-barrier. Shaded driveways will also last longer, as the shade significantly slows down the deterioration process.
Cleaner Water & Air
Roanoke Stormwater estimates that Roanoke’s current street trees intercept 107 million gallons of water per year, which not only helps to prevent flooding but also cleans the water by filtering out pollutants. Trees also filter pollutants from the air, with the current trees in Roanoke removing around 211 tons of air pollutants per year. Trees create a healthier environment which leads to healthier people and a better world. They are even known to reduce stress and anxiety. So what are you waiting for? Add trees to your landscape, get a great return on your investment and reap all the many benefits they have to offer. Plant some trees today!
As we mentioned in this month’s newsletter, bee populations are suffering at an alarming rate across the globe and especially in North America; where some 700 species are in decline. And while some would find that to be music to their ears, the ramifications for that decline could be devastating to our future. Yes, bees sting and annoy us from time to time, but they’re also essential to the global food supply. A third of our diet comes from plants pollinated by bees.
What’s causing the bees to die out? Scientists have cited a number of factors including insecticides, parasites, disease and the lack of a diverse food supply. The loss of biodiversity and destruction of habitat also threaten bees and other wild pollinators. It’s becoming increasingly evident that some insecticides, at concentrations applied routinely in the current chemical-intensive agriculture system, have a clear negative effect on the health of pollinators. The growing pest and weed resistance, decreasing soil fertility and widespread water contamination have also contributed to their downfall.
The global food supply already has trouble keeping up with the demand, but without bees it would become nearly impossible. Who would pollinate all the crops? Pollinating by hand is extremely labor-intensive, slow and expensive. So, from an economic standpoint, it pays to protect the bees. In fact, the economic value of the bees’ pollination work has been estimated at around $300 billion annually, worldwide.
Another major factor threatening our bees is the Varroa mite; a parasite that’s been plaguing honeybees since its introduction in the mid 1980’s. Introduced in Florida, the Varroa mite has since traversed the continent, wreaking havoc along the way. Watch the video below to learn more about these parasitic mites and the effects they have on bee colonies.
So how do we save the bees? With so many factors affecting their decline it’s an ambitious mission, but over the years a number of non-profits and conservation groups have teamed together to tackle the issue. They’ve lobbied against bee-killing insecticides in industrial agriculture and (as seen I the video above) have created some great products to stop the dreaded Varroa mite. Scientists are even experimenting with altering bee genetics, in an attempt to make them more tolerant of adverse weather conditions and immune to disease.
Another way you can help is quite simple; by incorporating bee-friendly plants into your landscape. At any rate, we must come up with a solution quickly to save our bees, our food supply and potentially our entire planet. If you want to do your part in saving the world’s greatest pollinators, check out the list below to see the best plants for bees.
Because outdoor living spaces increase the amount of usable space a property has, they are a great investment. Long lasting and consistently popular, an outdoor entertainment area will easily boost your property’s value and make your home more attractive to potential buyers. If you want your outdoor living space to truly be an investment, invest in high-quality materials and builders who won’t cut corners in order to give you a cheaper product (i.e. Roanoke Landscapes). You are essentially investing in another room for your home, so you want to put just as much care into your outdoor living space as you do your kitchen, bedroom, or living room.
Just how much does an outdoor living space increase the value of your home? It’s a question we get a lot and for good reason; everyone wants a good return on investment. Yes, having a beautiful outdoor fireplace or kitchen is just that, beautiful, but (as for any renovation) you want to be increasing the overall value and appeal of your home. It turns out that a lot rests on your location and the neighborhood trends. For instance, a pool might be a great investment in one neighborhood, but would actually hurt the re-sell value of your home in another part of town. Furthermore, high-maintenance outdoor living areas, such as pools, are usually a make or break factor in the sale of a home.
If you really want to increase the value of your home, then we suggest going with a low-maintenance interlocking concrete paver patio. A patio with a fire pit is even better. Not only can you gather around the fire for most of the year, a fire pit returns over 75% of your initial investment (according to a report by CBS). They’re also a great reason to get your family outside and enjoying your landscapes.
Outdoor kitchens and eating areas are becoming increasingly popular and will also see the value of your home skyrocket. There are tons of pre-fabricated options to choose from and installation is a breeze (relatively speaking). Another way to increase the value and curb appeal of your home is to add landscape lighting. Cost-effective and truly a unique look, landscape lighting will surely make you stand out in the neighborhood. Check out our latest landscape lighting project below:
The outdoor living area that remains the most sought after feature of a home is a deck; and they can be just as valuable as a patio. According to a study by Remodeling Magazine, an $11,000 deck can add about $9,000 in resale value to a home, seeing homeowners recoup around 82% of the project’s costs. You can check out our most recent deck installation below:
If you want to increase the curb appeal and value of your home, but don’t want to commit to an outdoor living project, try redoing your landscape. Roanoke Landscapes will help with choosing the right plants and with the overall design of your landscape. The National Association of Realtors says that an outdoor makeover can net over a 100% return on investment, not to mention you will love the new look. So what do you have to lose? If you want to create a peaceful outdoor oasis, while also increasing your home’s desirability, then add an outdoor living area to your property this season. And, if you need additional information on curb appeal and tricks to increase your home’s perceived value, check out this article from Turf Magazine here.
We can’t stress enough about the importance of aerating and over-seeding your lawn in the fall. It’s paramount in the quest for a year-round healthy and beautiful landscape. A thin landscape that hasn’t been over-seeded will inevitably be overrun with weeds at the first signs of spring. Moreover, pre-emergent will prevent any new grass-seed from even growing. However, if you absolutely have to over-seed in the spring there is a solution; Tupersan. It’s the only pre-emergent herbicide that will provide the control of crabgrass and weeds while allowing desirable turfgrass to germinate and thrive.
Tupersan is often paired with a complete fertilizer, such as the 12-24-11 pictured above, but you should always read the labels to ensure that the fertilizer and Tupersan are a good match for your landscape. The following information can be found on the Tupersan label:
WEEDS CONTROLLED: Annual weed grasses such as Crabgrass
(smooth and hairy), Foxtail (green and yellow) Barnyardgrass
(Watergrass). This product will not control Poa annua. This product
will not control established weeds that are already growing.
WHERE TO USE: For use on Bluegrass, Fescue, Redtop,
Perennial Ryegrass, Smooth Brome, Orchardgrass and certain
Bentgrass strains (Penncross, Seaside, Highland, Astoria, Nimisila,
C1, C7 and C19). Do not use on other Bentgrass varieties since
injury may occur. Do not use on Bermudagrass.
HOW MUCH AND WHEN TO USE:
FOR NEW SPRING SEEDINGS: Apply 2.5 pounds per 1000
square feet to treat and feed lawn where bare ground or very thin
turf is seeded in the spring and 2 weeks prior to weed seed
germination. Follow good cultural practices of keeping area moist
to help grass seed germinate and also to activate the pre-emergent
herbicide and to get maximum benefit from the lawn food.
FOR NEW “FALL” SEEDING OR SEEDING TO ESTABLISHED
LAWNS IN THE SPRING: Apply 5 pounds per 1000 square feet to
treat and feed turf. Apply in spring prior to the expected emergence
of the annual weed grasses. This will vary from early February in
the south to early March in the north. Follow the application with a
thorough watering (1/2 inch) to activate the herbicide.
HOW TO APPLY: To insure best weed control and proper
fertilization the lawns should be free of leaves, grass clippings or
thatch which might interfere with the pre-emergence action of the
herbicide. Complete all cultural practices such as aerification
before application. Apply with a properly calibrated fertilizer
spreader. If it does not rain within 3 days after application, water the
area thoroughly to get desired results.
RESEEDING TREATED AREAS: This product may be applied to
the soil at the same time as sowing grass seed. When used as
directed on listed turfgrasses this product will not affect the
germination of those seedling grasses.
As stated above, it’s extremely important to read the labels for pre-emergent, fertilizers, or anything else you plan on introducing into your landscape. Tupersan is an incredibly effective pre-emergent that, when used as directed, will prevent spring weeds and also allow new grass to flourish. If you have any questions about Tupersan, or questions on how to keep your lawn looking picture-perfect, give us a call at 540-772-0079. We offer free estimates and would love to make your landscape shine!
