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.

Weed Management
|
|
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.

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.
