How to Use This Guide
The first section covers the stuff that applies to all of Florida: climate, soil, water, pests, fertilizing. Read that first, then go straight to your region's month-by-month calendar.
Variety names follow each plant name directly. They're not random picks, every one was chosen for Florida's conditions: heat tolerance, disease resistance, humidity, and how we actually grow here. In Florida, variety choice matters more than technique.
Florida's Climate
Before variety selection, before soil prep, before anything else — understand what Florida's climate actually asks of you. It's the single biggest reason that gardening advice written for the rest of the country doesn't work here.
The Three Regions
| Region | Zones | Character |
|---|---|---|
| North Florida | 8a–9a | Four seasons, frost likely Nov–Mar, chill hours available |
| Central Florida | 9a–9b | Mild winters, light frost possible Dec–Feb, long fall season |
| South Florida | 10a–11 | Tropical, frost rare, year-round growing, distinct rainy/dry seasons |
Summer: June–September
The hardest stretch. Temps in the low-to-mid 90s, humidity that makes it feel worse, and afternoon thunderstorms rolling in almost daily. The experienced Florida gardener plans around summer, not through it. Summer is for heat-tolerant crops, mulching, soil building, and patience.
Hurricane Season: June 1 – November 30
Harvest anything ripe as soon as a storm enters the forecast. Don't fertilize in the two weeks before a predicted storm. Stake tall plants before the season. Move containers indoors or lay them on their sides. After the storm, wait two to three weeks before replanting into waterlogged soil.
Winter Freezes: The New Reality
The winters of 2022, 2023, and 2024 brought freezes well outside historical norms. Keep frost cloth within reach from November through March, regardless of your region.
Minimum Safe Temperatures
| Plant | Minimum Safe Temp |
|---|---|
| Citrus (mature) | 26°F briefly |
| Satsuma / Kumquat | 20°F |
| Avocado (Lula, Brogdon) | 28°F |
| Mango (most varieties) | 32°F |
| Banana (above-ground) | 26°F — top dies, roots usually survive |
| Papaya | 32°F — very sensitive |
| Basil | 50°F — damage starts here |
| Tomatoes | 32°F |
| Collards / Kale | 20°F — frost actually improves flavor |
Soil
Florida soil is mostly fine sand. It drains fast, warms quickly, and is easy to work. What it lacks is organic matter, nutrient-holding capacity, and structure. Plants in unamended Florida sand will look perpetually hungry no matter how much fertilizer you add — the nutrients wash straight through.
Building Soil Over Time
The goal over multiple seasons is to push organic matter from Florida's typical 1% or less up to 4–5%. Tools: compost before each season, wood chip mulch on top of beds, and occasional cover crops between seasons.
Cover crops worth using in Florida: Sunn hemp (summer, fixes nitrogen), cowpeas (summer, edible and soil-building), crimson clover (winter, nitrogen-fixing, cold tolerant in North FL). Cut and drop at flowering — don't let them set seed.
Water
Florida gets 50 to 60 inches of rain per year — but sandy soil drains it within hours, and the dry season (November through April) can go weeks without meaningful rainfall. You cannot assume rain is watering your garden.
How to Water
Water in the morning, always. Evening watering leaves foliage wet overnight — open invitation to fungal disease. Water deeply and less frequently. The best test: stick a finger an inch or two into the soil before you turn on the hose. Still moist? Skip it.
Four inches of wood chips or pine straw cuts your watering frequency in half, keeps roots from cooking in August, and builds your soil as it breaks down.
Pests & Disease
Florida's warmth means pests and pathogens never get a hard winter reset. Walk your garden weekly, turn leaves over, look for frass and stippling and slime trails — combined with the gentlest effective treatment.
Common Pests
Whiteflies
Florida's most universal garden pest. Yellow sticky traps help with monitoring. Neem oil (applied early morning) suppresses them. Reflective silver mulch physically confuses them.
Aphids
Cluster on tender new growth. Knock off with a hard water spray, then follow with neem oil. Attract or release ladybugs, lacewings, and parasitic wasps — your best long-term allies.
Leaf-Footed Bugs & Stink Bugs
Hand-pick into soapy water in early morning when sluggish. Row covers on young plants prevent infestation.
Tomato Hornworm
A massive green caterpillar that can strip a plant overnight. Hand-pick; apply Bt at first sign. Don't kill a hornworm covered in white cocoons — those are parasitic wasp eggs doing the work for you.
Root-Knot Nematodes
Nearly universal in Florida sandy soil. Stunted plants, knobby swollen roots. Rotate crops every season. Dense French marigolds as a cover crop measurably suppress nematode populations.
Spider Mites
Fine webbing and stippled bronze leaves. Increase humidity, apply neem oil. Avoid miticides early — they kill the predatory mites that would control the problem naturally.
Fungal & Disease Problems
Powdery Mildew
White powder on leaves. Improve airflow. Avoid overhead watering. Apply potassium bicarbonate or neem oil at first sign.
Early & Late Blight
Brown spots and yellowing, working up from lower leaves. Remove affected leaves immediately. Apply copper fungicide. Choose resistant varieties.
Citrus Greening (HLB)
Mottled yellow leaves and lopsided bitter fruit. Incurable, spreads by Asian citrus psyllid. Control the psyllid aggressively.
Anthracnose
Black spots on mango and avocado during rainy season. Apply copper fungicide preventatively before the rains arrive in May. By the time you see symptoms, it's too late.
Fertilizing
Florida's sandy soils drain nutrients fast. Light, frequent applications work better than one heavy feeding. Split your annual fertilizer budget into three or four applications through the growing season.
| Plant Type | Recommendation |
|---|---|
| Vegetables | Balanced 10-10-10 or 6-6-6 every 4–6 weeks. Side-dress with blood meal mid-season for nitrogen boost on heavy feeders. |
| Tomatoes & Peppers | Low-nitrogen, high-phosphorus starter at transplant (5-10-5). Switch to balanced or high-potassium once fruiting. Calcium foliar spray prevents blossom-end rot. |
| Citrus | Citrus blend with full micronutrients (8-4-8 typical). Apply February, June, October. Never fertilize after September in North FL. |
| Mango & Avocado | 6-6-6 plus micronutrients. February, June, October. Back off nitrogen once trees mature — too much suppresses flowering. |
| Blueberries | Acid-specific fertilizer (ammonium sulfate or azalea blend). Light in early spring, skip summer, apply again in early fall. Sensitive to overfeeding. |
| Native Plants | None after the first season. Over-fertilizing produces lush, pest-prone growth. |
| South FL Alkaline Soil | Supplement with chelated iron and micronutrient blend regardless of NPK levels. Alkalinity locks out trace elements. |
