NICEVILLE, Fla. — The month of May is usually a relatively dry and warm month. During most Mays, it’s almost as if someone knows where a switch is for water and for heat and they cut the switch on for heat and off for water.
If you take a look at the historic weather pattern for North Florida, we usually have relatively mild, spring-like temperatures and adequate moisture during March and April. But as we move into the month of May, the rain stops and the temperatures become warmer.

Then, as we move out of May into June and July, the rains come back but the temperatures remain warm.
The sudden change in temperature and moisture as we move into May can make it a challenge in gardening in North Florida. But there is plenty to do during May in our lawns, landscapes and gardens.
Just be sure to water to carry your plants, particularly newly planted ones, through any dry weather if this May ends up being an average May.
In today’s article, I’ll share with you the UF/IFAS Extension North Florida Gardening Calendar for the month of May. The link for this calendar is below.

Annuals/Bedding Plants: Plants that can take summer heat include salvia, angelonia, wax begonia and ornamental pepper. See Annuals/Bedding Plants: https://edis.ifas.ufl.edu/publication/mg319
https://gardeningsolutions.ifas.ufl.edu/plants/ornamentals/summer-bedding-plants.html
Bulbs: Planting early, mid and late-blooming varieties of daylily, ensures months of color from these low-maintenance plants. See Daylilies: https://edis.ifas.ufl.edu/publication/EP006 and Bulbs for Florida: http://edis.ifas.ufl.edu/topic_bulbous_flowers
Vegetables: Okra will take the heat as well as southern pea and sweet potato. See Vegetable Gardening in Florida: http://edis.ifas.ufl.edu/topic_vegetable_gardening
What to Do
Pests: Insects become more active in warm weather. Watch for thrips, scales and mites on ornamental plants. See Landscape Pest Management: http://edis.ifas.ufl.edu/topic_landscape_pests
Gardenias: Yellowing of older leaves is usually normal; yellowing of new growth usually indicates a micronutrient deficiency. See Gardenias at a Glance: http://edis.ifas.ufl.edu/ep338
Oleanders: Inspect chewed or ragged leaves for oleander caterpillars. See Oleander Pest Management: http://edis.ifas.ufl.edu/topic_oleander_ipm
Lawn insects: Watch for damage from chinch bugs in St. Augustinegrass and begin scouting for newly hatched mole crickets in lawns. See Turfgrass Pest Insects: http://edis.ifas.ufl.edu/topic_turf_pest_insects
