1) Keep your vegetable garden well watered during hot, dry spells. It's best to give most plants about an inch of water a week.
2) If you irrigate your vegetable garden, avoid doing so in late afternoon or evening. Give the moisture a chance to evaporate before the temperatures start to drop. Also: Avoid getting foliage wet whenever possible, especially on disease-prone species such as tomatoes and squash.
3) You can sow a fall crop of bush beans now. Plant seeds two inches deep to protect them from the hot Sun. You can sow other vegetable seeds for an autumn yield, too, by planting them just a little deeper than you did in the spring. The best time to plant is after a rain shower.
4) Don't allow vegetables to rot on the vines -- or fall off and decompose in the soil. Fallen fruit attracts pests and can harbor disease.
5) Pinch basil and other herbs periodically if you don't harvest it weekly. Pinching keeps it from flowering and ensure you have a full, bushy-looking plant.
6) Prevent weeds from seeding; this will mean fewer weeds next year. Pull weeds as they grow and use mulch in your flower beds to prevent them from sprouting.
7) If you want fresh, baby potatoes, begin digging them when the plants start to produce blooms. Otherwise wait a little longer until the potato plant begins to turn brown.
8) If you see white butterflies are flitting among your vegetables, you'll soon spot green worms feasting on cabbage family crops (cabbage, broccoli, brussel sprouts). Treat plants with Bacillus thuringiensis (Bt), a natural bacterium. Caterpillars consume Bt when they munch on treated leaves, and the bacteria kill them.
9) If you're dealing with flea beetles or Mexican bean beetles on vegetables, spray crops with an organic control like pyrethrum. Be sure to coat leaf undersides.
10) Mulching is an important job to keep up with in July. Organic mulches break down over time, so be sure to check the mulch around your plants. Keep a 3- to 4-inch layer of mulch around your plants to retain moisture. Also keep a thick layer of mulch around the roots of trees and shrubs.
