What to Plant
Annuals/Bedding plants: Try ageratum, celosia, zinnia, and wax begonia for color in the fall.
Bulbs: Add color, texture, and patterns to the garden with the many varieties of elephant’s ear (Alocasia spp.), calla, narcissus, and zephyr lily.
Herbs: Plant Mexican tarragon, mint, rosemary, and basil.
Fruits & Vegetables: It is time to establish strawberry plants. Veggies to plant now are broccoli, carrots, cabbage, collards, and many others.
What to Do
Lawns: Continue to monitor the lawn for signs of insect damage. Fall armyworms, chinch bugs, mole crickets, and sod webworms are still active this month.
Fertilizer Bans: Numerous municipalities in South Florida prohibit the application of fertilizer to lawns and/or landscape plants during the summer rainy season (June–September). See if such an ordinance exists in your area.
Vegetable gardens: Prepare the fall vegetable garden if not done in August. Using transplants from your local garden center will get the garden off to a fast start, but seeds provide a wider variety from which to choose.
Perennials and bulbs: Divide and replant perennials and bulbs that have grown too large or need rejuvenation. Add organic matter to planting beds and monitor water needs during establishment.
Irrigation: Check that irrigation systems are providing good coverage and operating properly before summer rains taper off.
Citrus: Fertilize citrus with a balanced fertilizer either this month or in October. Use controlled-release nitrogen because rain will not leach it from the soil too quickly.
