Radishes are the perfect way to kickstart the gardening season. These crisp, flavorful tubers require minimal care – just a little water and patience – and reward you with a fresh, homegrown harvest in just a few weeks.
When and How to Sow Radishes
Radishes can be sown as early as late February and continue growing until September. For a continuous supply, sow a new row every 2–3 weeks. These hardy vegetables thrive even at temperatures as low as 5°C, making them one of the first crops you can start outdoors. Raised beds provide an excellent growing environment, especially if they are covered with a cold frame to offer extra warmth and protection.
Growing Radishes in Small Spaces
No garden? No problem! Radishes are so adaptable that they can be grown in balcony boxes or large pots. Use a well-draining mix of garden soil, potting soil, compost, and a bit of sand to create the ideal growing medium. To maintain soil health and prevent disease, avoid planting radishes in the same spot more than once every three years. However, if growing in raised beds, regularly refreshing the soil can eliminate the need for crop rotation.
Sowing and Spacing for a Healthy Harvest
For optimal growth, sow seeds about 1 cm deep in small furrows, spacing them 4 cm apart. Maintain a row distance of at least 10 cm. Overcrowding can lead to excessive leaf growth at the expense of root development, so thinning is essential for well-formed tubers. Cover the seeds lightly with soil and water gently.
Caring for Radishes
Radishes need consistently moist soil but should never sit in standing water. With proper watering and spacing, you can start harvesting your first spicy, crunchy radishes in just 4–6 weeks.
A Bonus Harvest: Radish Leaves
Don’t discard those vibrant green leaves! Radish greens are packed with flavor and nutrients, making them a great addition to salads. Freshly harvested radishes and their leaves bring an unmistakable taste of spring to your kitchen.
