  • August 2025
  • By Burnt Store Meadows

In Florida, August is a hot and humid time for gardening. To make the most of the water, monitor your irrigation system’s zones and timings. Appreciate the cooling qualities of shade trees. Plant heat-tolerant plants and plan for the future.

WHAT TO PLANT

Annuals/Perennials/Wildflowers: The hottest days of summer limit planting to heat-tolerant vinca, coleus, pentas, salvia, and celosia. Remove spent blooms, cut back, and fertilize flowering plants to extend the bloom season. See
