WHAT TO DO

Shrubs and trees: Prune when new growth begins after the end of the dormant season. Prune after the last flowers fade but before new flower buds set.

Mulch: Add mulch to plant beds to minimize weeds and conserve moisture during dry weather. A ring of mulch around trees will protect them from damage by lawnmowers and line trimmers.

Pests: Monitor landscape plants for insects, especially for the presence of aphids on tender new growth. Insects become more active during warm weather.

Lawns: Identify damaging insects and spot treat early to prevent widespread damage. Turfgrass Pest Insects: https://edis.ifas.ufl.edu/topics/insect_management_in_your_florida_lawn. Apply a preemergence weed killer (not a “weed and feed”) to lawns to prevent germination of warm-season weed seeds. Apply when temperatures rise to 65°F for 4–5 days. Timing is important for good control.

Citrus: Squiggly lines in the younger leaves of citrus trees indicate Citrus Leaf Miner (CLM) insects, but there is seldom a need to manage them. Natural enemies in Florida usually keep them in check.
