Chinch Bugs out in Full Force

We typically see chinch bug and white grub damage to our lawns this time of year. It is beginning to show up in some areas with heavy infestation and damage.

First signs of infestation with chinch bugs appears as yellowish to brown patches of grass and they get larger and larger as summer progresses if not controlled. Before you know it you have a lawn that looks dead. Many times if left uncontrolled, you will have bermudagrass and weeds that will grow in the infected area.

An easy way to check for chinch bugs is to dig a 6x6 inch square area of the lawn adjacent to the dead grass area and shake if over whitepaper and you will see the adults and nymphs if present on the paper. Don’t get the plug area from the dead area of grass as the bugs have moved on to the greener grass.

Chemicals used to control the insects include Acephate, Talstar 10 WP and Carbaryl (Sevin 50% or 80% WP).

Also, white grub damage shows up at this time. This is the immature form of June Beetles. The c-shaped larvae are easy to spot when you shovel a 6x6 inch square of sod about 4-6 inches deep and separate the soil. The grubs can be controlled and need to be treated if three or more grubs are found in a square foot area.

Control chemicals are Sevin 50 or 80 percent WP, Merit 0.2 percent G and Mach 2G.

Vegetables to Plant in August

Plant bush snap and lima beans. You can also plant seed trays of broccoli, Brussels sprouts, cauliflower, Chinese cabbage, collard greens, cucumbers, squash, southern peas, mustard greens and shallot sets.

You can transplant broccoli and Brussels sprouts as early as mid-to late August.

You can start lettuce seeds and plant beet seeds in late August, early September.

Things to do:
  • Plant sunflowers in late summer for fall flower arrangements. It usually takes 60-80 days from sowing seed until first flower color.
  • Louisiana irises are semi-dormant in late summer. Prune off seed pods and yellow or brown foliage to help keep the plants more attractive.
Question: When should I prune ever-blooming roses?
Answer: Prune them back about one-third their height and fertilize them in late August or Early September. Also remove any dead canes and weak spindly growth. DO NOT cut back once-blooming roses, which only bloom in spring and early summer and stop blooming because pruning now will reduce flowering next year.
