1. Can I still prune my azaleas and other spring-flowering shrubs?
Yes, anytime after flowering and until about the first or second week of September; then next year’s flower buds are produced on stems that grow this summer for next year.
2. Why are the leaves of my camellia plants puffy and puffy?
You are infected with a disease called exobasidium, or more commonly camellia leaf bile. Slight infections of the leaf bile can be pinched or cut away by hand; For more severe infections, remove any diseased leaves, then spray your plants with a recommended fungicide such as Daconil or FungAway.
3. Can I plant millipede grass on my lawn now?
Yes. Now through early August is the best time to plant centipede seeds; Centipede sod can now be successfully planted through the end of August.
4. Why did most of the small fruits fall from my fruit tree?
One possibility is something called a “June Drop”. The cause of this are pollination problems. When fruit trees produce flowers, they must be pollinated in order for fruit to grow. Trees have one goal in mind: they must produce viable seeds in order to continue species. Shortly after the flowers have faded, small, pollinated and unpollinated fruits develop. Towards the middle to the end of June, the tree recognizes in which fruits viable seeds develop inside. And those that are duds are unceremoniously dumped.
5. Is there a pre-emergence herbicide that I can use to prevent volunteer shrubs from sprouting in my flower beds?
No, according to Dr. Tim Murphy, UGA weed scientist. Hand removal or gentle brushing on Roundup or Finale are options.
6. Can I fertilize my millipede again?
Always fertilize and add lime or sulfur based on a soil test. Millipedes grow best at a pH of 5.5 to 6.0. Fertilize with ½ to 1 pound of actual nitrogen per 1,000 square feet, depending on the type of soil, using a high potassium fertilizer like 15-0-15. Do this last fertilization before August 15th. To determine the amount of granular fertilizer it takes to apply ½ pound of actual nitrogen per 1,000 square feet, divide 50 by the first number on the fertilizer bag. To determine the amount of product required to apply 1 pound of actual nitrogen per 1,000 square feet, divide 100 by the first number on the fertilizer bag.
7. Can fungicides burn if used in higher amounts than stated on the label?
You certainly can, especially Daconil and Bayleton.
8. I have had my Bradford pear for eighteen years now and it still doesn’t make large pears, just small pears the size of a dime. Why?
The Bradford pear, Pyrus calleryana “Bradford”, is a purely ornamental pear and does not produce any edible fruit.
9. What is the correct height to mow my centipede lawn?
Mow grass to 1 inch. Don’t let the grass grow taller than 11⁄2 inches. NEVER burn millipedes to remove excess debris.
10. How much water does my sweet corn need?
Sweet corn needs plenty of water from germination to harvest, but the most critical time for water is about 2 weeks before silk forms. Aim for 1 inch of water per week and supplement natural rainfall with irrigation as needed. They begin to elongate from the ovules 10 to 14 days before growth stage R1 or around the V12 leaf stage.
