April yard and garden tips from Clemson Extension

Things to do


• Bulbs—You should be planting your summer and fall-flowering bulbs in April and May, such as dahlias, gladioli , cannas, and lilies. Be sure to plant after the soil temperature reaches 55 degrees F.

• Dividing— It’s time to divide fall blooming perennials.


• Spray fruit trees— It’s time to begin spraying your fruit trees with a fungicide (Captan, etc.) every seven to 10 days to provide the beautiful fruit you look forward to. Do not use any insecticides on the trees until less than 10% of the blooms remain—you certainly do not want to hurt your bee pollinators. The fungicide will have no effect on them.


• Add i ron— Centipede and St. Augustine lawns will appreciate an application of iron this month to bring out a richer green color without stimulating excessive growth.

• Fire ants—If you broadcast baits, apply your first treatment during the last week of April or the first week few weeks of May. Be sure to apply fresh bait, and do it at the correct time of day ( fire ants only forage actively when the ground temperature is between 70 and 95 degrees F).
