Use a tree-and-shrub product at the rate specified on the label. If you haven't yet fertilized your warm-season grass (Bermuda, St. Augustine, or zoysia), do so at this time. Sow Your Veggies Now that the soil has warmed, it's okay to sow seeds of vegetables that love hot weather. These include beans, corn, melons, okra, eggplants, tomatoes, and squash. Plant about ½ inch deep in a sunny spot. To get an earlier crop, you can buy small plants from the garden center. Spray Camellias Tea scales are little brown or white insects that suck sap on the undersides of camellia leaves and cause them to turn yellow. This can be prevented by spraying the undersides now with horticultural oil according to label directions. Throw out any fallen camellia leaves to prevent tea scales from spreading further.
