Weed Control

Early management of all of these weeds is important. Their root systems develop quickly making them difficult to pull from the ground. Deep mulch layers make it harder for the weeds to get established. Weeds may still grow, but they are easier to pull. Mulch may also prevent weed seeds from getting soil contact needed for germination.

What: Weeds are plants growing where we don't want them. A rose in a cornfield is a weed. It's all in the location.

Threat Level: Low for plant health if caught early. Serious for peace of mind if weeds get out of control.

Treatment Category Effectiveness Notes
Mulch Cultural Practice High Mulch should be several inches deep to prevent weeds from germinating and getting started in soil.
Frequent Grass Cutting Cultural Practice High Mulch should be several inches deep to prevent weeds from germinating and getting started in soil.
Pulling Weeds Cultural Practice High
When Caught Early
This sounds obvious: pull the weeds to control them! Catching them in early growth stages is much easier and more likely to succeed. Weeds with extensive root systems have reserve energies to regrow many times.
Corn Gluten Meal Organic Practice Fair Corn Gluten Meal sold in large bags can help prevent weed seed germination when spread at a rate of 40 pounds/1,000 square feet. Timing is essential: apply just as weeds begin to germinate in late summer and just as spring starts.
