Radishes are one of the first vegetables ready for harvest in the spring. Most varieties have a maturity date of approximately 25 days from planting, and you can sow the seeds every 10 to 14 days until the weather turns hot. Radishes are also planted in mid-summer for a fall crop. Winter storage radishes grow larger and do not mature until 50 to 70 days after planting. Edible pod radishes are grown for their seedpods, which mature in 50 days. Growing conditions affect the final maturity date, so consider the harvest dates printed on seed packets to be estimates.

When you plant the seeds, record the expected maturity date.

Step 1

Record the expected maturity date for each radish variety the day you plant the seeds. Use a waterproof marker to write the date on a plastic row label or jot it in a notebook.

Step 2

Check the radishes five to seven days before the maturity date by pulling one from the ground. Harvest the sample radish by grasping the bottom of the foliage near the soil and firmly pulling upward. If the radish is 1/2 to 1 inch across, the crop is ready to harvest.

Step 8

Harvest the pods when they are the thickness of a pencil for peak flavor. Pick a rat-tail radish by grasping the small stem at one end of the pod and bending it to the side until it snaps it off where the stem attaches to the branch.
