When to Plant Radish Seeds

Radishes are a cool-season crop that can be planted in early spring or late summer for a fall harvest. It is important to plant radishes at the right time, as they will not grow well in hot weather. In most regions, it is best to plant radishes in the spring as soon as the soil can be worked, and in the late summer about 4-6 weeks before the first expected fall frost.

Planting radish seeds is a simple process that can be done directly in the garden or in containers. Here are the steps to plant radish seeds:

  1. Choose a sunny location with well-drained soil for planting your radish seeds.
  2. Prepare the soil by removing any weeds and rocks, and then tilling it to a depth of about 6 inches.
  3. Create shallow furrows in the soil about 1/2 inch deep and space the seeds about 1 inch apart.
  4. Cover the seeds with soil and gently press down to ensure good soil contact.
  5. Water the seeds well and moisten the soil until the radish seedlings emerge.

Caring for Your Radish Plants

Once your radish seeds have been planted, it is important to provide them with proper care to ensure a healthy and productive crop. Here are some tips for caring for your radish plants:

Water regularly

Radishes require consistent moisture, so be sure to water your plants regularly, especially during dry spells.


Apply a balanced fertilizer to your radish plants about 2-3 weeks after planting.


Once your radish seedlings have emerged, thin them to about 3 inches apart to allow room for the radishes to grow.


Apply a layer of mulch around the base of your radish plants to conserve moisture and suppress weeds.

Control pests

Keep an eye out for common pests such as cutworms, flea beetles, and cabbage maggots, and take action if necessary to control these pests.

Harvesting Your Radishes

Radishes are a fast-growing crop that can be harvested in just a matter of weeks after planting. Here are some tips for harvesting your radishes:

Know the growing time

The growing time of different radish varieties can vary, so be sure to check the seed packet or consult a gardening guide to determine the average growing time for your chosen variety.

Check for size

Radishes should be harvested when they are the desired size, usually 1-3 inches in diameter for round varieties, and 2-3 inches long for elongated varieties.

Test for firmness

Radishes should be firm and crisp when ready to harvest. If they feel soft or spongy, they have likely been left in the ground too long and will not have the best flavor.

Pull gently

To harvest your radishes, gently pull them from the ground, taking care not to damage the roots of surrounding plants.

Storing Your Radishes

Once harvested, radishes should be stored in a cool, dry place to preserve their freshness and flavor. Here are some tips for storing your radishes:

  1. Wash and dry: Rinse your radishes well to remove any dirt or debris, and then pat them dry with a clean cloth or paper towel.
  2. Trim the tops: Cut the tops off of the radishes to prevent moisture from entering the roots and causing them to spoil.
  3. Store in the refrigerator: Wrap your radishes in a paper towel or place them in a plastic bag with small air holes and store them in the refrigerator. They should keep for several weeks.
