When to plant green beans in Florida.
Sow between Feb 3 to Mar 26 in a typical year, keyed to Florida's median last frost around Feb 3. A second, fall sowing fits Aug 31 to Oct 3. Dates below are state medians; your ZIP code shifts them by days to weeks.

Green Beans dates for a typical Florida season.
Direct sow
Feb 3 to Mar 26
Keyed to the ~Feb 3 last frost. Sow 1" deep, 3" apart.
Fall round
Aug 31 to Oct 3
Counted back from the ~Dec 15 first frost.
Harvest
~55 days later
~0.75 lb per plant over ~3 weeks.
Florida spans more than one climate: Zone 9 is the most common zone, but the state runs 8b to 11a. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
Florida growing notes
South Florida's muck ground ships snap beans north all winter.
The Everglades belt runs on a different calendar than your yard
The winter vegetable belt south of Lake Okeechobee, built on rich black muck soil rather than the sand that covers most of the rest of the state, grows snap beans commercially through the exact months when the rest of the country cannot, shipping north through the coldest stretch of the year. A home gardener anywhere in Florida is working the same basic calendar logic even without that muck soil underneath: beans here are fundamentally a cool-season crop, planted to mature during the mild months rather than the brutal summer.
Florida's mild winter stretches the bean-friendly temperature window far longer than almost any other bean-growing region gets, which is why growers here treat succession sowing as routine rather than a stretch goal: drop a new short row every couple of weeks and the picking basket never really empties out. Sow a full inch deep once soil holds a steady 60 degrees, with germination speeding up further as the reading climbs toward 70 to 80.
Root-knot nematode is the sandy-soil threat this crop can't outrun
Away from the Everglades muck, most Florida garden soil is sand, and sand is exactly the texture root-knot nematode moves through most easily, since the microscopic pest needs loose ground to travel and reproduce in. Beans are a genuine host for it, and an infected plant shows stunted, yellowing growth above ground while the roots below develop small rough galls that choke off the plant's ability to take up water even when the bed looks adequately watered.
Rotate the bean row to a different part of the garden each year rather than replanting the same strip season after season, and avoid following tomatoes or okra with beans in the same bed, since both host the same nematode and let the population build rather than break. A county extension soil test can confirm nematode pressure directly if a planting has struggled without any pest visible above ground.
Mexican bean beetle keeps working through a mild winter
Mexican bean beetle, a copper, spotted beetle easily mistaken for a ladybug at a glance, does not slow down through a Florida winter the way it would further north, since the state's mild cold snaps rarely knock the population back hard between rounds. The spiky yellow larvae feed in tight clusters on leaf undersides, and a colony can hollow a planting's foliage into lace before the damage becomes obvious to anyone glancing at the bed from a normal standing distance.
Check leaf undersides weekly through the entire growing window here, not just during the warmest months, and crush any yellow egg clusters found before they hatch. Rust and powdery mildew both spread fastest through humid, still air, so keeping the row weeded and watering at the soil line rather than overhead does real work toward controlling both across Florida's long, humid growing season.
In Florida: watch for
The pests that find green beans here.
With about 315 frost-free days, bush bean spends longer in the ground here than in most of the country, which widens the window in which mexican bean beetle can find it. Scout weekly from midseason and act on the first signs.
Coppery ladybug-like beetles; leaves skeletonized to lace.
Organic fix: Handpick adults and yellow egg clusters; neem.
Orange or white spots on leaves late in the season.
Organic fix: Water at the base, space plants, spray neem.
Anthracnose
Sunken dark-red cankers on the pods, and leaf veins turning brick-red to black underneath.
Organic fix: Start with certified seed, water at the base, and stay out of the patch while the leaves are wet.
Your season math: Florida gives green beans about 315 frost-free days, and it needs roughly 55 days to a first harvest. That fits about 27 re-sown rounds across the season, so you can keep it coming instead of picking once.
Planting green beans in Florida: questions
When should I plant green beans in Florida?+
In a typical Florida year, sow green beans between Feb 3 to Mar 26, keyed to the state's median last frost around Feb 3. There's also a fall window: Aug 31 to Oct 3. Your exact dates shift with your ZIP code and microclimate.
What USDA zone is Florida?+
Florida spans zones 8b–11a, mostly zone 9. But frost dates, not zones, set planting time. The free planner uses your ZIP code's actual frost dates.
How many green beans plants do I need?+
Depends who you're feeding. The crop page has exact counts per household size, or the free planner does the math for your family in about 60 seconds.
