Weed Services FAQs, answered by experts

Weeds can grow through rubber mulch, but it depends on if you removed all the weeds in your garden beforehand. Weeds already in the soil can grow even when using rubber mulch. However, that doesn’t mean that your garden will be littered with rubber and weeds, but it does mean that the occasional weed might still pop up. Another way you can increase your weed suppression is by using landscape fabric as a second layer. 

Herbicides containing a combination of the active chemical ingredients dicamba, fluroxpyr, and quinclorac are most effective at purging your turf of white clover. However, for small home lawns, organic prevention and control can be very effective methods for killing clover weeds and save you from using harmful pesticides that might damage your lawn.

They compete for nutrients and water, potentially stunting desired plants.

Look for a broadleaf herbicide, one that has been formulated specifically for dandelions and is considered grass-safe.

The best time to fight crabgrass with pre-emergent herbicide is when forsythias tend to bloom. In the mid-Atlantic region, this is usually between April and May. Even if you're late to apply the herbicide, it’s effective as long as the crabgrass plant has fewer than five leaves.
