Winter Annual Weeds

Posted by John Fulton -

Each year, the winter annual weeds chickweed and henbit run number one and two in the early spring. This year is seems like henbit is running slightly ahead. Winter annual weeds can actually germinate in the fall, carry through the winter, then get going very early in the spring. They also are done by the heat of the summer, leaving seed to germinate again later in the fall. Right now chickweed stands out in yards because it is quite abundant, and has a lighter green color than grass and most other weeds. I can't begin to tell you how to identify it, it gets even harder when there is common chickweed and mouse-ear chickweed. Henbit is easier to identify since it has purple flowers and smells like mint. As for control, that gets a bit easier.

The straight 2,4-D that is used on dandelions seems to act like a fertilizer for chickweed and other problem weeds. Combinations that contain 2,4-D, MCPP, and dicamba are rated very effective on chickweed, henbit, red sorrel, purslane, white clover, and others. Just remember the control time for most broadleaf weeds is early May. These combinations are sold under several different trade names. You can find these at most hardware, discount, and lawn and garden stores. Just check the label under active ingredients and check for two long chemical names and dicamba. You can also check to see that it says it will control chickweed and henbit. This group of chemicals is effective in the 50 degree range and up. As with any chemical control, read and follow label instructions very carefully. There will be some cautions on these product labels concerning injury to sensitive plants that you should be aware of. This is because dicamba can drift as a vapor for a few weeks after you apply it if the weather gets hot and sunny.
