What to plant
Annuals/Bedding plants: Plant heat-tolerant annuals, such as coleus, vinca, and portulaca.
Bulbs: Cannas thrive in the heat of summer. New varieties have colorful leaves as well as flowers. See Bulbs for Florida:
Herbs: Some to start now include basil, coriander, cumin, and mint.
Vegetables: Beans, Chinese cabbage, Southern peas, and sweet potatoes can still be planted. Mulch beds well and monitor irrigation if the weather is dry.
What to do
Plant for butterflies: Plant flowers of different colors, shapes, sizes, and blooming seasons to provide nectar for adult butterflies and provide host plants for their caterpillars.
Pests: Monitor insect activity and learn which bugs damage plants and which do not.
Beneficials: Identify and conserve beneficial insects. Some insects should be encouraged in your yard!
Tomatoes: Watch for pests, disease, and nutritional disorders on developing tomato plants.
Palms: Identify and treat environmental and nutritional disorders in palms.
Oleanders: Inspect chewed or ragged leaves for oleander caterpillars at work.
Fruits: Propagate fruit crops by air layering and grafting.
Perennials and bulbs: Divide clumps of bulbs, ornamental grasses, or herbaceous perennials to expand or rejuvenate garden beds or to pass along to friends.
Shrubs: Choose from a wide variety of shrubs to add to the landscape now. Remember Right Plant/Right Place and match the mature size with the location.
