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.
