Copper fungicide is labeled for control of certain diseases that invade avocado and mango trees. Spray weekly until the small fruit appears and monthly until June or July. February is the month to fertilize lawns. Check the label as to application rates. Reading the label is important since recommendations vary.
Many products advise the user to apply when the grass blades are dry, and then to water thoroughly.
Some lawn fertilizers also contain a weed-killer. Be sure your grass is named on the label. The misuse of herbicides can damage or kill grass or landscape plants. Crape myrtles can be pruned this month. Pruning is best done while the plants are dormant.
