Getting to Know Radishes
When you think of radishes, you probably envision the small, round, red, and tangy root vegetable that is commonly found in salads. However, radishes come in a variety of shapes, sizes, and colors, ranging from hot to mild in flavor. They belong to the Brassicaceae family, which includes other popular vegetables like broccoli, cabbage, and kale. Radishes are annual vegetables that can be planted in the spring for a spring harvest or in late summer for a fall harvest.
How to Plant Radishes
When to Plant
- Direct seed radishes in the garden in early spring as soon as the ground is workable.
- Sow seeds weekly for a continuous harvest.
- Plant again in late summer, at least four to six weeks before the first fall frost.
Selecting a Planting Site
- Choose a sunny spot with rich, loose, well-draining soil.
- Container growing is an option for small spaces.
- Plant radishes between slower-growing plants like carrots in the vegetable garden.
Spacing, Depth, and Support
- Sow seeds 1/2 inch deep and 1 to 2 inches apart.
- Thin seedlings to 3 inches apart.
- Rows should be spaced 3 inches apart.
- Support structure is not necessary.
Radish Plant Care
Light
- Radishes need full sun for at least six hours a day.
- Lack of sunlight can result in leafy growth instead of root development.
Soil
- Radishes thrive in rich, loamy, or sandy soil with a slightly acidic to neutral pH.
- Avoid heavy or compacted soil that can inhibit root growth.
Water
- Water radishes weekly with 1 inch of water.
- Maintain soil moisture by mulching around the plants.
Temperature and Humidity
- Radishes prefer temperatures between 40 and 70 degrees Fahrenheit.
