Beetroot is one of the most rewarding crops for home gardeners. They are resilient, space-efficient, and offer a double harvest of both earthy roots and nutritious greens. Whether you are a seasoned horticulturalist or a first-time gardener, learning how to plant beetroot correctly ensures a bountiful harvest of sweet, tender vegetables. This guide covers everything from soil preparation to the final pull.
Understanding Beetroot Varieties
Before you dig your first furrow, it is important to choose the right variety. While the deep crimson globe is the most common, beets come in a surprising array of colors and shapes.
- Detroit Dark Red: This is the standard for classic red beets. It is reliable and stores well.
- Chioggia: Often called the “Candy Cane” beet, it features stunning red and white concentric circles inside.
- Golden Detroit: These yellow beets have a milder, sweeter flavor and do not bleed red juice when cooked.
- Cylindra: These elongated, carrot-shaped beets are perfect for uniform slicing and maximize space in small beds.
Selecting the Ideal Planting Site
Beetroots are relatively easy-going, but they perform best when their basic needs are met. They require a spot that receives full sun for at least six to eight hours a day. While they can tolerate partial shade, the roots will develop much slower in low-light conditions.
The soil is the most critical factor for success. Beets prefer well-drained, sandy loam with a neutral pH between 6.0 and 7.0. Because they are root crops, they need stone-free soil. If the soil is too heavy or rocky, the roots may become stunted or misshapen. Avoid soil with excessive nitrogen, as this encourages lush leaf growth at the expense of the root.
Preparing the Seedbed
Preparation begins a few weeks before planting. Clear the area of weeds and large stones. Incorporate well-rotted compost or organic matter into the top six inches of soil. This improves drainage and provides the steady supply of nutrients beets crave.
Avoid using fresh manure. High nitrogen levels can cause roots to fork. If your soil is heavy clay, consider planting in raised beds. This allows for better control over the soil texture and drainage.
When to Plant Beetroot
Beetroot is a cool-season crop. It can withstand light frosts but struggles in intense summer heat. For a spring crop, sow seeds as soon as the soil is workable and has reached at least 50°F (10°C). This is usually two to three weeks before the last expected frost.
To ensure a continuous supply, practice succession planting. Sow a new batch of seeds every two to three weeks until the temperatures begin to climb in mid-summer. For a fall harvest, sow seeds again in late summer, about six to eight weeks before the first hard frost of autumn.
The Sowing Process
Beet “seeds” are actually small clusters of multiple seeds called fruits. This means that each “seed” you plant will likely produce a small clump of two to four seedlings.
- Pre-soaking: Soak your seeds in lukewarm water for 12 to 24 hours before planting. This softens the outer shell and speeds up germination.
- Sowing Depth: Plant seeds about half an inch (1 cm) deep.
- Spacing: Space seeds one to two inches apart within the row. Leave about 12 inches of space between rows to allow for easy weeding and airflow.
- Covering: Lightly cover the seeds with soil and firm it down gently with your hand to ensure good seed-to-soil contact.
Care and Maintenance
Once your seedlings emerge, which typically takes 7 to 14 days, the real work begins. Consistent care is the secret to tender, non-woody beets.
Thinning the Seedlings
Because each seed pod produces multiple plants, thinning is essential. When the seedlings are about two inches tall, remove the weaker plants to leave one strong seedling every three to four inches. Do not pull them out by the roots, as this can disturb the remaining plant. Instead, snip them off at soil level with scissors. The thinnings are edible and make a great addition to salads.
Watering
Beets need consistent moisture. Dry spells followed by heavy watering can cause the roots to crack. Aim for about an inch of water per week. Mulching with straw or shredded leaves helps retain moisture and keeps the soil cool.
Weeding
Beets do not compete well with weeds. Keep the area clean, but be careful when hoeing near the base of the plants. The roots are shallow and easily damaged. Hand-weeding is often the safest method around the developing bulbs.
Harvesting and Storage
You can begin harvesting “baby beets” when the roots are about the size of a golf ball. These are incredibly tender and sweet. For full-sized beets, wait until they are two to three inches in diameter. Beets larger than this can become tough and fibrous.
To harvest, gently loosen the soil around the root and pull. Twist off the leaves rather than cutting them to prevent the root from “bleeding” its juice. Leave about an inch of the leaf stems attached.
Store beets in the refrigerator for up to two weeks. For long-term storage, keep them in a cool, dark, and humid environment like a root cellar, packed in damp sand or sawdust.
Frequently Asked Questions
Why are my beetroots small and woody?
Small, woody roots are usually the result of overcrowding or high temperatures. If the plants are not thinned properly, they won’t have room to expand. Additionally, if the soil dries out completely, the plant enters a survival mode that toughens the root tissue.
Can I grow beetroot in containers?
Yes, beetroot grows very well in containers. Ensure the pot is at least 10 inches deep and has excellent drainage. Use a high-quality potting mix and water more frequently than you would for ground-planted beets.
Do I need to fertilize my beets?
If you prepared your soil with compost, you might not need additional fertilizer. However, a balanced organic fertilizer applied mid-season can help. Avoid high-nitrogen blends; instead, look for something with a higher phosphorus and potassium content to support root development.
Why are the leaves of my beets turning red or purple?
While many varieties naturally have red-veined leaves, an overall purple tint can sometimes indicate a phosphorus deficiency or cold stress. If the weather has been very cold, the color usually returns to normal as it warms up.
What pests should I look out for?
Leaf miners are the most common pest. They leave trail-like tunnels in the leaves. You can prevent them by using row covers or simply removing affected leaves. Aphids can also be a problem but are easily managed with a sharp stream of water or insecticidal soap.
