WHAT TO DO

Lawns: Continue to check the lawn for signs of insect damage. Fall armyworms, chinch bugs, mole crickets, and sod webworms are still active this month. Lawn and Garden Care: Pest Management: https://edis.ifas.ufl.edu/topics/lawn-garden-pest-management

Fertilizer bans: Numerous Florida municipalities prohibit applying fertilizer to lawns and/or landscape plants during certain months. Does such an ordinance exist 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.

Divide and replant: Some clumping plants may need dividing. Add organic matter to planting beds and check water needs during establishment. Lawn and Garden Plants: Seeds and Propagation: https://edis.ifas.ufl.edu/topics/lawn-garden-propagation

Irrigation: Check that irrigation systems are providing good coverage and running properly before summer rains taper off. Lawn and Garden Care: Irrigation: https://edis.ifas.ufl.edu/topics/lawn_and_garden_care_irrigation

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. Home Citrus Culture: https://edis.ifas.ufl.edu/topics/home_citrus_culture
