When to Plant Radishes in Arkansas

The fastest vegetable in the garden — some varieties are ready in just 25 days. Perfect for impatient gardeners and kids.

The Short Answer

In Arkansas, soil conditions are an important factor for radishes. Heavy clay in lowlands. Rocky soil in Ozarks. Raised beds recommended for drainage. Direct sow 4 weeks before your last frost date. Radishes can also be planted in fall, 6 weeks before your first frost.

Growing Radishes in Arkansas

Radishes in Arkansas's Climate

Radishes are a cool-season sprint in warm climates — sow from October through February and harvest before spring warmth triggers bolting. Succession plant every 2 weeks during the cool window for multiple harvests. The quick maturity (22-30 days) means you can fit several rounds into even a short cool season.

Soil Considerations for Arkansas

Heavy clay in lowlands. Rocky soil in Ozarks. Raised beds recommended for drainage. Loose, well-drained soil is especially important for radishes since the edible portion grows underground. If your soil is heavy clay, consider raised beds.

Arkansas Climate & Growing Season

Hot, humid summers. Moderate winters. Good growing conditions for most vegetables. Radishes can handle frost well, which is an advantage in Arkansas's climate. You can push planting dates earlier in spring and extend into fall.

Growing season length varies across Arkansas: Northern Arkansas (6b, 7a) has a last frost around Apr 5 - Apr 20, while Southern Arkansas (7b, 8a) sees frost end around Mar 15 - Apr 1. This difference matters for radishes — but radishes handle frost well, so the timing difference is less critical.

Growing Tips

Don't let them stay in the ground too long — they get pithy and hot. Succession plant every 2 weeks for continuous harvest.

Companion Planting

Plant radishes alongside these companions for better growth:

Peas Lettuce Carrots Spinach

The Bottom Line

Radishes can be grown successfully across Arkansas, but your exact planting dates depend on which region you're in. Northern Arkansas gardeners should plan around a Apr 5 - Apr 20 last frost, while those in Southern Arkansas can typically plant earlier.
