Foggy mornings pale
Seared from sight by blazing sun
Nectarine juice drips
Aside from watering, August may seem like the perfect time to take a break form the heat, but there are still plenty of garden tasks to choose from!
While ants do help aerate the soil, they can also damage crops and spread disease. Fruit trees can be protected with sticky barriers. Boric acid bait traps can be an effective control method, just be sure the baits are placed where children and pets cannot reach them.
Unlike other trees, which are pruned when they are dormant, apricot trees are best pruned in summer. Apricot trees are susceptible to a fungus called Eutypa dieback, which can infect trees if rain reaches fresh pruning cuts.
This is the time of year when Japanese beetles, dried fruit beetles, and June beetles are the easiest to see (and eliminate). Japanese beetles will skeletonize many plants. These pests tend to cling to their favorite foods and are easy to knock into cans of soapy water. [I used to pay the neighborhood children a nickel for every June bug they eliminated - very useful in Virginia!] June bugs are clumsy fliers and easy to slap down with a net. Both can be fed to chickens. Dried fruit beetles and June bugs do not bite or sting and dogs can be trained to chase and kill them before they lay eggs in the soil. These eggs will later hatch and the larvae will devour lawn, ornamental, and other plant roots.
Just as in April and June, oranges and other mature citrus trees should be fed one-half pound of nitrogen in August. Blood meal is an excellent source of nitrogen, without all the fillers. Ammonium sulfate is another good source of nitrogen.
This is the time of year when all that hard work and patience really pay off. Keep plants healthy and enjoy the fruits of your labor by harvesting frequently. This reduces the number of places where pests and diseases can hide. This also prevents many plants from going to seed and ending fruit production. When harvesting tree fruit, be sure to keep a look out for mummified fruit. Remove mummies and dispose of them in the trash, not the compost pile.
If you have a lawn and it has not turned completely brown, allow it to grow longer than you would in cooler months. Taller grass protects the soil and helps retain moisture. And be on the lookout for masked chafers and southern chinch bugs.
Mite infestations often look like nothing more than light webbing around leaves and stems. This webbing is followed by leaf stippling, chlorosis, and leaf drop. Water-stressed plants are more susceptible, as are dusty plants. Mites are related to spiders. Adults have eight legs, but the young only have six. Spraying pesticides often backfires because mite predators, such as lacewings and pirate bugs, are killed. Often, you can use a soft-bristled brush to dislodge these pests.
By August, most rain barrels have run dry, making this the perfect time to clean out any debris in the remaining grey water, along with any mosquito larvae. West Nile Virus, Zika Virus, and many other diseases are transmitted by mosquitoes, so it is important to regularly eliminate any standing water. Mosquito dunks should be added to any standing water every 30 days.
Hot weather means trees need more water. Trees planted in a lawn that is being watered regularly will still need a deep watering 2 or 3 times during the summer, or more, depending on the weather. Stand alone mature fruit and nut trees will need a deep watering every 3 - 4 weeks, while younger trees will need to be watered every 2 weeks. Ideally, there is an irrigation ring around each tree at the drip line.
August is an excellent time to start seeds for winter crops. Spinach, beets, lettuce, arugula, broccoli, Brussels sprouts, cabbage, cilantro, bush beans, fava beans, leeks, radishes, and peas can all be started in small containers for transplanting after summer crops are done. This gives you a head start on the cooler growing season, just be sure to keep the soil moist. A thin layer of vermiculite can help retain moisture.
