Gardening Checklist for July-August

Outside work this time of year should be confined to early morning hours (before noon) or after 6:00 in the evening. If at all possible, avoid being out in the sun during the hottest part of the day. If this isn’t possible, be sure to protect yourself from harmful ultraviolet rays with sunscreen, and for good measure, wear a broad brimmed hat. Don’t forget to take frequent rest breaks and drink lots of water.

Things you could be doing if ambition strikes include:

• Water lawns and gardens only when needed, giving a thorough soaking rather than frequent light sprinklings. Be sure to obey the City of Austin rules for lawn watering. Minimize water loss by doing your watering in the early morning when the humidity is high and winds are generally light.
• Removing faded flowers from plants (deadheading) before they set seed will keep them growing and producing more flowers. A light application of fertilizer every 4 to 6 weeks will also be helpful.
• Check plants and flower beds for mulch. Replace or add where needed.
• Watch for and apply early control for summer insects and diseases to prevent a build up or spread.
• Caladiums require plenty of water at this time of year if they are to remain lush and active until fall. Fertilize with a high nitrogen fertilizer like 21-0-0 and water thoroughly.
• Keep a close check on recently planted plants. Inadequate root systems combined with drought can be devastating.
• Check your lawn mower. Be sure the blade is sharp. With hot weather here, the mower blade should be in its highest position.
• Start working on your fall vegetable garden. Spading and/or tilling in compost and otherwise getting your garden ready for planting should begin now. Tomato and pepper plants for the fall garden could be set out in early August (plan to shade them for a few days.). Okra and winter squash should be planted by late July or early August, followed closely with green (snap) beans and cucumbers. Plan to set out broccoli, cabbage and cauliflower plants in late August or early September.
• Keep an eye out for powdery mildew, especially on crepe myrtle. A formula using 4 teaspoons of baking soda and onehalf teaspoon of dishwashing detergent mixed into a gallon of water and sprayed on the affected plants generally controls it. Or better yet, start a regular spraying program, which will prevent it from occurring in the first place.
• Going on vacation? Here are a few suggestions to keep lawn and garden looking nice while you are gone: 

a. Mow your lawn and water it thoroughly before leaving. Your lawnmower should be at its highest setting.
b. Apply mulch to all areas of your flower and vegetable garden.
c. Cut back annuals and perennials to encourage new growth and flowers for your return.
d. Arrange to have your yard watered as necessary while you are away. If you will be gone more than a week or ten days, you probably should have someone mow your lawn. That should be enough to keep you busy. Just remember to take it easy. You are more important than your garden.
