This product may be applied to established lawns as a single application or as split applications in the spring, early summer, or fall. For the best results in the spring, apply this product one to two weeks before the expected germination of crabgrass. When the period of germination for crabgrass and other weeds listed on this label extends into early summer, then a second application can be made at six to ten weeks after the initial application.
Apply the product when grass and weeds are actively growing under adequate soil moisture and favorable temperatures (50°F to 80°F). Do not apply under drought conditions.
In the spring, the ideal time to apply Preen One Lawncare is after the forsythia has bloomed or when the first dandelion flowers appear. For full weed control in lawns in southern areas, make a second application in six to eight weeks for best weed and crabgrass control and for full season fertilization. In the fall, apply Preen One Lawncare when the weather cools and both the grass and weeds are actively growing, generally around Labor Day.
For established lawns, apply Preen One Lawncare when broadleaf weeds are actively growing and prior to germination or tilling of annual grasses. It may be applied as a single application or as a split application in spring, summer, or fall.
You can reseed or overseed a lawn treated with Preen One Lawncare 10 weeks after application.
If the lawn has been seeded recently, wait until after the third mowing before using this product.
For optimum weed control in lawns, apply Preen One Lawncare to grass when the lawn is wet from rain, dew, or sprinkling, as this product needs to stick to the leaves of broadleaf weeds. The lawn should not be watered or disturbed for at least 24 hours after application.
For best results, we recommend that you:
- apply when no rain is expected in the next 24 to 48 hours – preferably 48 hours
- not mow the area to be treated for 3 days before application and 3 days after application
- apply to a wet lawn (for example, wet from morning dew, irrigation, or recent rain)
- do not irrigate the treated area after application for 24 to 48 hours – preferably 48 hours
Apply this product when the wind is calm. Do not apply this product to desirable plants or shrubs as damage may result. If the product gets onto other plants, immediately brush or wash it off the foliage.
Use a drop or rotary spreader designed to apply granular fertilizers. Uniform coverage is essential for best results. It should take approximately 2 to 4 weeks to see the label-listed broadleaf weeds succumb.
For use on established bahiagrass, bermudagrass, buffalograss, centipedegrass, fine fescues, Kentucky bluegrass, perennial ryegrass, tall fescues, and zoysiagrass.
DO NOT use on St. Augustinegrass, colonial bentgrass, dichondra, or carpetgrass as serious lawn injury will result.
This product is not for use:
- on dichondra, carpetgrass, colonial bentgrass or turf mixes including desirable clovers, or St. Augustinegrass in Florida
- within 25 feet of open water including rivers, streams, fish ponds, lakes, and marshes
- where it can enter or wash into storm drains or drainage ditches
- where the water table is shallow and soils are permeable, near wells or cisterns
- within the drip line of desirable trees and shrubs
Note: Do not use clippings of treated grass as mulch or in compost piles.
