When to plant radishes in Texas

Planting dates

For a spring crop, Texas A&M says to sow radish seed as soon as the soil can be worked. Radishes do poorly in hot summer months. For fall, identify your Texas gardening region first, then use its average date to plan the bed.

Your region

Texas A&M lists five average fall planting dates, from September 1 in Region I to December 15 in Region V. Check the guide’s gardening-region map before choosing a row. These dates help you plan the season; they do not establish a county forecast or the result for every radish variety.

How to plant

Make a furrow one-half inch deep. Sow seed about 1 inch apart, cover it lightly with loose soil, then water. Texas A&M says seedlings can emerge in 4 to 6 days; loose, well-drained soil helps the roots expand without becoming misshapen.

Keep the harvest moving

Texas A&M suggests sowing short rows 8 to 10 days apart for a steady supply. Stop when the garden enters hot conditions. The schedule gives each sowing its own start date, so harvests will not all arrive at once.

Too late or too long?

Texas A&M gives about 4 to 5 weeks from planting to harvest. Begin thinning when roots start expanding, then harvest while roots are young and tender. If a late planting would run into heat, wait for the next cool-season window instead of forcing the crop.
