Time to apply pre-emergent for crabgrass control
Announcements All Locations
Posted on: March 7, 2016 by Dian Roberson
Crabgrass can be difficult to control in lawns after it has germinated. Now is the time to apply a pre-emergent herbicide to control crabgrass and some other broad leaf weeds. A pre-emergent herbicide is one that kills seedlings as they emerge. To be effective they need to be applied before the weed pest appears. Here is some information about identifying crabgrass and how to control it.

Fall Garden Pests Remain Active

Aphids and Beet Leafminer
Posted on: September 17, 2015 by Ariel Agenbroad
The weather is cooling off, but some insect pests are enjoying a resurgence in the garden.
Watch your fall brassica crops like cabbage, kale and broccoli for new generations of aphids, they are flourishing in the cooler temperatures. Spray any insects off with a stream of water or use an insecticidal soap.
Also watch for leafminer damage in your late season spinach, beets and Swiss Chard. Removing and disposing of any affected leaves is the best strategy at this point in the season. For next year, use a protective row cover to keep the flies off their favorite crops!
For more information on both of these pests, visit the links below.
