Laura Jarvis from Rainbow Gardens, a horticulturists says it's not too late to fertilize your yards but you can't wait too long. Another week or two may be too late. Fertilizing your trees and plants now is still a good idea. Jarvis says there is no exact cut off date on fertilizing but the key is to do it before the heat builds up.
What about planting? What kinds of plants should I be planting at this point? Jarvis says look for what she called "hot weather" plants like Hibiscus, Vincas and Bougainvilleas. She says these plants are great in South Texas and handle the heat very well.
