Growing beets from existing beetroots is a fascinating project that connects gardeners to the life cycle of one of the world’s most versatile vegetables. While most people grow beets from seeds to harvest the earthy roots, growing them “from beets” usually refers to one of two methods: regrowing greens from kitchen scraps or planting a mature root to produce seeds. Both methods are rewarding and provide a sustainable way to enjoy fresh food and garden independence.
Understanding the Beet Life Cycle
To grow beets successfully from existing roots, you must first understand that the beet (Beta vulgaris) is a biennial plant. In its first year of growth, the plant focuses on developing its edible taproot and a lush rosette of leaves. In its second year, after a period of cold dormancy known as vernalization, the plant sends up a tall flower stalk to produce seeds.
When you attempt to grow a beet from a beet, you are essentially skipping the first half of the life cycle. You are moving straight into the leafy regrowth or the reproductive phase. This distinction is important because a replanted beet will not grow a new, larger bulb for you to eat later. Instead, it will provide you with nutritious greens or a massive supply of seeds for next season.
Method 1: Regrowing Beet Greens from Scraps
If your goal is to have a continuous supply of beet greens for salads or sautéing, you can easily regrow them from the tops of beets you bought at the grocery store or harvested from your garden. Beet greens are packed with vitamins A, C, and K, and they have a flavor similar to Swiss chard.

Step 1: Selecting and Preparing the Beet
Choose healthy, firm beets. Avoid those that are shriveled, soft, or showing signs of rot. When you are preparing your beets for cooking, do not cut the top off flush with the skin. Instead, leave about one inch of the root shoulder attached to the stems. This portion contains the crown, which is the “growth engine” of the plant.

Step 2: Rooting in Water
Place the beet tops in a shallow saucer or container. Add enough water to cover the bottom of the beet scrap, but do not submerge the top of the crown. Place the container on a sunny windowsill. Change the water every day to prevent bacterial growth and rot. Within a few days, you should see tiny green leaves beginning to emerge from the center of the crown.

Step 3: Moving to Soil
Once the leaves are an inch or two tall and you see small root hairs forming at the base, you can transplant the beet top into a pot filled with high-quality potting soil. Bury the scrap so that only the new green growth is visible above the surface. Keep the soil consistently moist. You can begin harvesting individual leaves once they reach a usable size.
Method 2: Growing for Seed Production
If you want to grow “new” beets from an “old” beet, the most effective way is to let the old beet go to seed. This is a common practice for homesteaders and heirloom gardeners who want to preserve a specific variety.
Selecting Parent Beets
For seed saving, you want to select the best “mother” roots. Look for beets that have the ideal shape, color, and size for their variety. They should be free of pests and diseases. If you live in a climate with mild winters, you can leave these beets in the ground over the winter. In colder climates, you must harvest them, store them in a cool cellar in damp sand, and replant them in the spring.
Replanting the Root
In early spring, dig a hole deep enough to accommodate the entire beet root. Place the beet in the hole and cover it with soil, leaving just the very tip of the crown exposed. Space multiple beets at least 12 inches apart, as the seed stalks can grow quite large.
Managing the Seed Stalk
As the weather warms, the beet will send up a tall, branched flower stalk that can reach heights of three to four feet. These stalks may require staking to prevent them from falling over in the wind. Beets are wind-pollinated, so if you are growing multiple varieties and want pure seeds, you should only grow one variety for seed at a time.
Harvesting the Seeds
The flowers are small and inconspicuous. Eventually, they will form “seed balls,” which are actually clusters of multiple seeds. Wait until the seed stalks turn brown and the seeds feel hard and dry. Cut the stalks and place them in a paper bag for a few days to ensure they are completely dry. Rub the stalks between your hands to release the seeds. You can then plant these seeds to grow a brand new crop of edible beetroots.
Optimal Growing Conditions
Whether you are growing for greens or for seeds, beets have specific requirements to thrive. They prefer cool weather, making spring and autumn the ideal seasons for growth.
Light Requirements
Beets need at least six hours of direct sunlight per day. If you are regrowing greens indoors, a south-facing window is usually necessary. If you lack natural light, a simple LED grow light can supplement the needs of the plant.
Soil and Nutrition
A loose, well-draining soil is essential. Beets do not like “wet feet,” which can cause the original root scrap to rot before it can produce new growth. Use a balanced organic fertilizer, but avoid those excessively high in nitrogen if you are growing for seeds. High nitrogen levels can encourage lush leaf growth at the expense of flower and seed development.
Watering Consistency
Consistency is the key to healthy beet growth. The soil should feel like a wrung-out sponge. If the soil dries out completely, the plant may become stressed and “bolt” (go to seed) prematurely or produce bitter leaves. Mulching around the base of the plant can help retain moisture and regulate soil temperature.
Common Challenges and Solutions
Growing from scraps or mature roots comes with a few risks. The most common issue is rot. Because you are planting a mature piece of organic matter, it is susceptible to fungus and bacteria. To prevent this, ensure your tools are clean when cutting the beet and do not overwater.
Pests like leaf miners can also be an issue. These tiny larvae tunnel through the leaves, creating translucent “trails.” You can protect your beet greens by using floating row covers or by checking the undersides of leaves regularly for small white egg clusters and squishing them.
The Benefits of This Approach
Growing beets from beets is a lesson in sustainability. It reduces food waste by utilizing parts of the vegetable that are often discarded. It also provides a sense of food security. By learning to save seeds from your own beets, you become less reliant on store-bought seed packets and more in tune with the natural rhythms of your local environment.
Furthermore, the nutritional value of fresh beet greens is significantly higher than those that have sat in a grocery store for days. By growing them on your windowsill or in a small garden plot, you have access to “living food” that can be harvested moments before it is eaten.
Frequently Asked Questions
- Can I grow a new large beet bulb from a beet top?
- No. Once a beet has grown its main bulb, it will not produce a second one. Replanted beet tops or roots will only produce leaves, flowers, and eventually seeds. To get more edible bulbs, you must plant the seeds produced by the plant.
- How long does it take for beet tops to grow new leaves?
- You will usually see new green sprouts within 3 to 7 days of placing the beet top in water or soil. You can typically start harvesting small leaves for salads within 3 weeks.
- Do I need to peel the beet before replanting it?
- No, you should never peel the beet. The outer skin protects the internal tissues from disease and dehydration. Keep the root as intact as possible, only trimming the very bottom if it is excessively long or damaged.
- Why did my replanted beet flower so quickly?
- Beets are triggered to flower by a process called vernalization, which is exposure to cold temperatures. If you replant a beet that has already experienced a winter or a long period of cold storage, it will naturally move into its flowering and seeding phase almost immediately.
- Are the leaves of all beet varieties edible?
- Yes, the leaves of all common garden beet varieties are edible. Some varieties, like ‘Bull’s Blood,’ are grown specifically for their deep red, ornamental, and tasty foliage, but even standard purple or golden beet leaves are delicious and safe to eat.
