Questions are coming in from gardeners concerned about weeds in their landscape, bugs in their bushes and diseases creeping up on garden plants.
This is a time when plants are maximizing all their growth processes and this can put the plants under stress due to the heat and drought we are still facing.
Because the heat wave is upon us, be careful when you are outside in this kind of weather. Take frequent breaks and replenish lost liquids as you work. We want you to enjoy your garden and not end up in the hospital.
Here are a few things to do and to be looking for:
Irrigate warm seasoned grasses this time of year as needed. Most lawns will need one and one-half inch of water each week. It is best to apply all at one time or split the application to make two three-quarter inch applications several days apart.
Watch for chinch bugs in St. Augustinegrass and be prepared to apply Talstar to control them. We have had numerous samples of St. Augustinegrass brought in with chinch bugs.
Weeds are really adaptive to the harsh conditions that prevail in the summertime. Check on your weed population, get the weeds identified, and control with the appropriate weed-control product. The best weed control strategy is to have a well-established lawn that prevents weeds from establishing.
Fertilize the warm seasoned grasses with one-half to one pound of actual nitrogen for our area, except for centipedegrass.
Continue to mow at the proper heights for the various grasses:
•Centipedegrass: 1–1.5 inches
•St Augustinegrass: 2.5–3 inches
•Bermudagrass: .75–1.25 inches
•Zoysia grass: .75–1 inch
•Tall Fescue: 3.5–4 inches
Watch for mole cricket activity–small tunnels at the soil surface. Merit is usually applied for mole cricket control in late May and followed up with an application of Talstar around the first part of July. If you haven’t already done so, it is getting late. Please do this right away if you are having problems with mole crickets.
Keep up with sprays for repelling deer. We were visited recently and sustained a lot of damage. They have stopped feeding since we sprayed the plants with the repellant.
