CRABGRASS & CRABGRASS CONTROL

What is crabgrass and how to get rid of it for good
?
The most prevalent species of Digitaria in North America are Large
Crabgrass (D. sanguinalis), sometimes known as Hairy Crabgrass; and Smooth
Crabgrass (D. ischaemum). These species often become problem weeds in lawns and gardens, growing especially well in lawns that are watered lightly,
underfertilized, poorly drained, and growing thinly. They are annual plants, and one plant is capable of producing
150,000 seeds per season. The seeds germinate in the late spring and early summer and outcompete the domesticated
lawn grasses and expand outward in a circle up to 12 inches in diameter. In the fall when the plants die they leave
large voids in the lawn. The voids then become prime areas for the crabgrass seeds to germinate the following
season. Crabgrasses also have a different texture and color that often interrupts the uniformity of a lawn. In
vegetable gardens, crabgrass can quickly out-compete desirable plants, causing
yield reductions. Crabgrasses can be controlled with pre-emergent herbicides that
interfere with a key enzyme when a seed germinates. These herbicides must be applied at a critical time. If they
are applied to the soil too early, they get washed too deep into the soil by rainwater. If they are applied too
late the key enzyme inhibited is no longer active. The rule of thumb is to apply when the local forsythia blooms are wilting.
