Growing Radish in Tampa

Tampa's Zone 9b subtropical climate makes it one of the best year-round gardening cities in the country. Frost is rare and brief. Two distinct growing seasons dominate: the warm/dry spring (March–May) and the fall (October–December) after summer's intense heat and rain subside. Summers are hot and stormy — tropical crops like sweet potatoes and okra thrive, but many gardeners rest cool-season beds until September.

In Tampa (last frost around January 28), radish can go out around December — approximately 6 weeks before the last expected frost, making it an early-season opportunity.

Radish thrives between 40°F and 65°F. It tolerates temperatures as low as 32°F, making it a candidate for early spring planting before the last frost date. Expect 22–30 days from transplant to first harvest. One of the fastest vegetables. Spring or fall.
