Growing Cucumber in Jacksonville
Jacksonville's Zone 9a climate means gardening is a year-round pursuit. Winters are mild enough for cool-season crops while summers support tropical vegetables. Humidity is high June through September, which requires vigilance against fungal diseases, but the extended season easily allows two or three successions of most crops.
In Jacksonville (last frost around February 20), aim to direct sow or transplant cucumber outside around March — approximately 2 weeks after your last expected frost. Starting seeds indoors 3 weeks before the last frost date gives you a significant head start.
Cucumber thrives between 65°F and 95°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 50–70 days from transplant to first harvest. Warm soil required. Direct sow preferred.
