The summer heat makes it difficult to work outside for long. But some chores in your landscape need to be addressed to keep your plants attractive and healthy.
Probably the most critical detail right now is the effect of this summer's recent record heat. Many plants can suffer from extended hot, dry conditions.
Allowing plants to get to the wilting point before watering may cause irreversible damage to some varieties, especially shallow-rooted annuals and perennials.
If water restrictions allow, give these plants a drink at night; or better, early in the morning to avoid the hottest part of the day and the greatest amount of evaporation.
Don't forget to water your most prized trees as well. It's easy to replace a $3 annual flower, but nearly impossible to restore a 50-year-old oak.

Many areas in Georgia are experiencing warm, humid weather with frequent thunderstorms this month. This is the perfect weather for fungal leaf spot development in the landscape. Most leaf spots are benign and will not damage the plant.
Cercospora Leaf Spot of Hydrangea is an example of a leaf spot disease that commonly occurs during prolonged wet weather or under sprinkler irrigation. As with most leaf spots in the landscape, chemical treatment is rarely needed. Some leaf spotting and leaf drop will not the harm the plant.
