2. Sweet Potatoes

Sweet potatoes are tuberous roots with a sweet flavour and high nutritional value. They are an excellent source of vitamins A and C.

Growing Tips: Start with slips, which are sprouts from mature sweet potatoes. Plant these in late spring, ensuring each slip has ample space to grow. Mounds about 8 inches tall and spaced 3 feet apart are ideal. They thrive in hot weather and need a side-dressing of balanced fertiliser a month after planting.

3. Beetroots

Beetroots are vibrant root vegetables known for their earthy taste and high folate content. They are excellent for detoxification and improving blood health.

Growing Tips: Sow beet seeds directly in the garden from early spring to early summer and again in fall. Soak the seeds overnight for better germination. Plant them 1 to 2 inches apart and thin the seedlings to 3 to 4 inches apart once they grow. Harvest when beets reach golf ball size.

4. Garlic

Garlic is a pungent bulb known for its medicinal properties and ability to enhance the flavour of dishes. It contains compounds that boost the immune system.

Growing Tips: Plant garlic cloves in the fall, placing them in a trench 5 to 6 inches deep. Add bone meal or a balanced fertiliser to the trench before covering the cloves with soil. Mulch well to protect from frost. Space the cloves 4 to 6 inches apart and rows 8 to 12 inches apart.

5. Onions

Onions are versatile bulbs that add depth to many dishes. They are rich in antioxidants and beneficial for heart health.

Growing Tips: Onions can be grown from seeds, sets, or seedlings. Start seeds indoors 6 weeks before the last frost, or plant sets and seedlings in early spring. Plant them in furrows 1 to 2 inches deep and space them 2 to 6 inches apart, depending on the variety. Keep the soil loose and well-watered.

6. Potatoes

Potatoes are starchy tubers that are a staple in many diets. They are packed with potassium, vitamin C, and dietary fibre.

Growing Tips: Use seed pieces of tubers with at least 1 or 2 eyes for planting. Potatoes are a cool-season crop, best planted in early spring. Place seed pieces in furrows and mound soil around the base as they grow to ensure plenty of loose soil for tuber formation.

7. Radishes

Radishes are fast-growing root vegetables with a peppery taste. They are excellent sources of vitamin C and can be round or cylindrical in shape.

Growing Tips: Sow radish seeds directly in the garden from early to late spring and again in fall. Thin the seedlings to 1 to 2 inches apart once they are an inch tall. Radishes mature quickly, often in less than a month, and should be harvested frequently for the best taste.

Growing underground vegetables is both easy and beneficial. These vegetables are rich in nutrients and add flavour to meals. With simple techniques and minimal space, anyone can cultivate these healthy crops. Start planting today and enjoy fresh, home-grown produce.
