Tip #1: Keep an eye on shrubs and trees that may require supplemental water.

During the "Dog Days of August" temperatures are usually at their hottest of the year in Zone 8 of the South. If we are experiencing a dry spell during this time, it may be necessary to provide supplemental water to newer plantings as well as older, well-established trees and shrubs. To water larger trees suffering from lack of moisture encircle the outer perimeter of the trees branch system with a soaker hose and deeply soak for several hours once or twice a week, or as needed. You may also want to apply a layer of mulch above the root sytems to help retain moisture. The root systems of larger trees and shrubs usually extend 10-20% beyond the diameter of the canopy.

Tip #2: Check Crape Myrtles for honey dew aphids.

Look closely on the underside of leaves to see if these tiny bright green insects are present. To eliminate aphids, spray the leaves with an insecticide labeled for use on crape myrtles. To prevent these pests from showing up in the first place an application of a systemic insecticide in February on Crape Myrtles and other shrubs, such as Azaleas and Roses, can be beneficial.

Tip #3: Check for fungus in lawn.

If expanding brown patches or circular rings of a light gray colored ash-like looking substance are forming in your lawn a fungus may be present. If so, broadcast a granular lawn fungicide or spray with a liquid fungicide. Your local nursery and garden center professional can advise you about fungal remedies for the lawn.

Tip #4: Fertilize annual flowers in beds and containers.

For increased flower production, apply a good flower fertilizer or natural flower food once every 4-6 weeks on annual flowers. Bloom boosting fertilizers usually have a high content of phosphorus, the middle number in fertilizer.
