Subject: Preemergence Annual Grass Control, Tree Seedlings, Wild Garlic

Preemergence herbicides for crabgrass and annual grass control can continue but should be wrapping up as Forsythia ends its blooming period. It is very important that these late applications get activated by rainfall or irrigation.

It is still too early for treating broadleaf weeds.

Tree seedlings in turf will mow out, an herbicide application is not needed.

Wild garlic is noticeable now. Ignore it and it will go away or treat with a broadleaf turf herbicide.  Control is increased if wild garlic is stepped-on or rolled before application. Granular broadleaf herbicide formulations should not be used. Digging and removing the bulbs can also be an effective strategy.
