SUCCESSFUL CONTROL INCREASES WITH PREVENTION
The rules of crabgrass control are really very simple. Do nothing, and your lawn stands the chance of being overrun by this clumpy, coarse-textured, all-around unsightly weed. Take preventative action, on the other hand, and crabgrass can be kept in check.
MAINTAINING HEALTHY TURF IS THE FIRST STEP
Every lawn has crabgrass seeds in the soil, and these seeds are more likely to grow when turf doesn’t receive adequate care. Regular fertilization, proper mowing, good watering practices, and insect and disease control will all help to maintain a thick lawn that is less likely to be marred by crabgrass.
PRE-EMERGENTS TAKE IT A STEP FURTHER
For even better control, pre-emergent herbicides can be applied to you lawn. As their name suggests, pre-emergent herbicides stop crabgrass plants from emerging by inhibiting seed germination in the soil. To get the best results from pre-emergent, proper application, timing and follow-up care are essential. Pre-emergent should be on the lawn before crabgrass seeds begin germinating.Yearly applications are needed for ongoing control.Slightly heavier applications along sidewalks, driveways and streets are helpful, since these areas are more susceptible to crabgrass infestation.Applications should be watered in within five to seven days if there’s no rainfall.Heavy raking, dethatching or any other mechanical disruption of,the soil is not recommended after pre-emergent have been put down, since this will break up the control zone.
While it’s true that crabgrass is a formidable and very persistent pest, it can be managed successfully. A proactive combination of good lawn care practices and pre-emergent applications is the key.
PLEASE NOTE: Pre-emergent herbicides will stop desirable grass seeds from growing as will. If you want to reseed you lawn, you should wait six to eight weeks after pre-emergent have been applied.
