How to Grow Radishes: A Beginner’s Guide
Radishes are one of the easiest and fastest-growing vegetables that you can plant in your garden, making them a great choice for beginner gardeners! They have a crisp and peppery flavour, which is great to add to various dishes, and packed with nutrients. Plus, radishes can improve your garden’s soil and act as a companion plant to deter pests! If you’ve never grown radishes before, this guide will help you get started.
When to Start Radish Seeds
Radishes thrive in cool weather, so they are best grown in early spring and fall. You can start planting seeds as soon as the soil is workable in the spring, about 4-6 weeks before your last expected frost. For a continuous harvest, succession plant your radish seeds every 10-14 days. In the fall, sow seeds 4-6 weeks before your first expected frost date to enjoy a late-season crop.
How to Plant Radishes
Radishes prefer loose, well-draining soil with plenty of organic matter. Follow these simple steps for planting:
Choose a Sunny Spot: Radishes need at least 6 hours of sunlight daily. I will be the first to admit they can tolerate some shade in the morning though. I plant them in a location that has sun from 12-6pm.
Prepare the Soil: Gently losen the soil 2-3 inches and add compost rich soil 2-3 weeks before planting.
Plant Seeds Directly in the Garden: Sow seeds about ½ inch deep and 1 inch apart in rows spaced 6 inches apart. Radishes do not need a lot of room to grow. Ignoring spacing rules is ok!
Keep the Soil Moist: Water after planting and regularly to ensure even moisture in the soil. Keep an eye on temperatures and water more if the weather heats up.
Thin your Seedlings: Once seedlings sprout, thin them to about 2-3 inches apart so each radish has space to grow properly.
Benefits of Growing Radishes in Your Garden
Radishes aren’t just a quick-growing, easy vegetable to have in your garden; they also provide many benefits:
Deters Pests: The scent of radishes repel unwanted pests and tend to confuse them making them a wonderful crop to grow in gaps in the garden.
Perfect for Succession Planting: Because radishes mature so quickly (often in just 3-4 weeks), you can grow them between slower-growing crops like carrots or tomatoes.
Health Benefits of Eating Radishes
Radishes are low in calories but rich in vitamins and minerals, making them a nutritious addition to your diet. Some key health benefits include:
Rich in Vitamin C: Supports a healthy immune system and promotes skin health.
Good for Digestion: Their fibre content helps with digestion and gut health.
Hydrating and Detoxifying: Radishes have a high water content and natural detoxifying properties that support liver function.
Harvesting Radishes
Radishes grow quickly and are usually ready to harvest within 3-4 weeks after planting! Check the seed packet for maturity dates. Some varieties like daikon can take up to 55 days. When the radish reached about 1 -1.5 inches in diameter, gently pull them from the soil. If left too long, radishes can become tough and woody. They will also split on the bottom. After harvesting, wash them thoroughly and store them in the refrigerator for up to one week. I like to store them in a jar in water to keep them crisp.
Growing radishes is a simple and rewarding experience for any gardener, and especially for beginners. With their fast growth, pest-repelling properties, and health benefits, they are a valuable addition to any garden. Whether you’re looking for a quick harvest or a companion plant to improve your soil, radishes are a great choice to add to your garden plan this spring and fall. Try planting some in your garden this season and enjoy the fresh, crisp flavour of homegrown radishes!
