Short on space but still want a productive kitchen garden? Root vegetables are an excellent choice especially compact varieties that thrive in containers, raised beds, or even window boxes. These underground treasures pack a nutritious punch while keeping your garden tidy and manageable. Whether you’re growing on a balcony, patio, or in a tiny backyard plot, these 10 compact edible root plants will deliver bountiful harvests in minimal space.
1. Radishes (Raphanus sativus)
Fast-growing and perfect for beginners.
Radishes are one of the quickest-growing root vegetables, often ready to harvest in just 25 to 30 days. They come in compact, globe or cylindrical varieties that fit perfectly in pots or tight garden rows. With their spicy, crisp texture, radishes are great for salads and pickling. Varieties like ‘Cherry Belle’ or ‘French Breakfast’ thrive in containers at least 6 inches deep and perform best in cool weather. Sow every few weeks for continuous harvests.
2. Carrots (Daucus carota var. sativus)
Sweet and satisfying, even in small pots.
Carrots are surprisingly container-friendly, especially short or round types like ‘Parisian’ or ‘Thumbelina’. These varieties only require 6–8 inches of soil depth and grow well in buckets, deep trays, or grow bags. They prefer loose, well-draining soil free of rocks or clumps. With full sun and consistent moisture, compact carrots develop rich sweetness and a crisp texture. Plus, their feathery foliage adds beauty to any container garden.
3. Beets (Beta vulgaris)
Double-duty roots and greens.
Beets are compact, fast-growing root crops that also offer edible leaves. They grow beautifully in containers 8–10 inches deep and need moderate spacing. Varieties like ‘Detroit Dark Red’ or ‘Golden’ are ideal for pot cultivation. With a sweet, earthy flavor, beets are excellent roasted, pickled, or juiced. Harvest them young for tender roots, and snip the greens early for salads and sautéed dishes. They thrive in cooler temperatures and are ideal for spring and fall gardens.
4. Turnips (Brassica rapa subsp. rapa)
Quick-growing and flavor-packed.
Turnips are often overlooked, but their compact size and quick growth make them excellent for small gardens. Baby varieties like ‘Hakurei’ are especially popular for container growing and can be harvested in just 30–40 days. They only need about 6–8 inches of depth and perform well in pots. Both the roots and leafy tops are edible, offering peppery greens and tender bulbs that are great in soups, stir-fries, or roasted dishes.
5. Garlic (Allium sativum)
A flavor essential that fits anywhere.
Garlic takes up minimal space and grows perfectly in pots or along the edges of beds. Plant individual cloves in fall for a summer harvest. Each clove will produce a full head of garlic with little maintenance. Garlic prefers full sun and well-drained soil, and softneck varieties are especially well-suited to container growing. Not only is garlic an essential kitchen staple, but it also deters garden pests and adds structure to small garden layouts.
6. Shallots (Allium cepa var. aggregatum)
Gourmet bulbs from tiny plots.
Shallots offer a mild, sweet onion flavor perfect for gourmet cooking, and they take up very little space. They grow similarly to garlic: plant small bulbs in the fall or early spring, and they’ll multiply underground into clusters. Shallots thrive in pots or raised beds with full sun and loose, well-drained soil. Compact and tidy, they can be tucked into corners of herb gardens or grown alongside leafy greens.
7. Baby Potatoes (Solanum tuberosum)
Small spuds, big yield in containers.
Yes, you can grow potatoes in containers! Choose early or mini varieties like ‘Yukon Gold’, ‘Red Norland’, or fingerlings for best results. A 10–15 gallon grow bag or deep pot works well. Start with a few seed potatoes, and keep adding soil as the plants grow (a process known as hilling). In 60–90 days, you’ll harvest delicious baby potatoes. Container-growing keeps pests at bay and makes harvesting incredibly easy.
8. Kohlrabi (Brassica oleracea var. gongylodes)
Space-saving and surprisingly versatile.
Kohlrabi is an unusual-looking but tasty vegetable with a bulbous stem that grows just above the soil. It only needs about 8–10 inches of soil depth and doesn’t require much room to grow. The crisp, mildly sweet bulbs can be eaten raw, roasted, or sautéed, and the greens are edible too. Varieties like ‘Purple Vienna’ or ‘Early White’ mature in as little as 45 days, making them a fast and fun choice for compact gardens.
9. Scallions (Allium fistulosum)
Continuous harvest with minimal effort.
Also known as green onions, scallions are one of the easiest and most space-efficient root crops to grow. They can be grown close together in shallow containers (4–6 inches deep) and harvested as needed. Scallions thrive in sunny locations and can even regrow from the white root ends after cutting. They’re perfect for window boxes, vertical planters, and kitchen gardens, offering fresh flavor for months with very little fuss.
10. Horseradish (Armoracia rusticana)
Bold flavor in a compact root.
If you love spicy condiments, horseradish is a surprisingly easy root to grow in containers and it’s best kept there to contain its aggressive spread. Plant a root cutting in a deep pot and watch it flourish. After one growing season, you’ll harvest a thick, white root that can be grated for a fresh, pungent kick. It’s a low-maintenance plant that thrives in full sun to part shade and stores well through winter.
