FALL GROWING GUIDE · REGION V
When to plant
radishes
in Rio Grande Valley.
Radishes belong to the short-season group in the fall guide. They can fit into a plan that leaves room for repeated small sowings instead of a single large crop.
AVERAGE FALL PLANTING DATE

Direct sow · Frost tolerant
A recurring regional reference from the 2014 Extension guide. This is not a forecast; the source does not specify a closing date for this crop.
What this means for your garden.
The far southern tip of Texas, including McAllen on the source map, is Region V. This is the latest fall schedule in the five-region guide, with some sowings extending to mid-December.
For radishes, the regional reference is December 15. The source provides no last optimum date for this crop. Dates that look late compared with northern gardens are intentional in this regional table. Check the source region before importing advice from a different climate.
Your next three steps
- Choose the right start.
A short maturity period is useful, but it does not remove the need for suitable growing conditions. Start with a small test row if you are uncertain.
- Give the plant a good first week.
Check the seed packet for spacing and harvest timing. Mark each sowing date so roots from different batches do not become one indistinguishable row.
- Keep a record you can use next season.
Save your planned date, then change it to the day you actually plant. Record completion in My Garden; the reference calendar stays separate from your own history.
