Sprouts or Direct Seeding? Choosing the Right Way to Start Beets
You can plant beets straight into the ground or start them as seedlings indoors. Both methods work, but they give slightly different results and suit different conditions. Here’s how to decide what fits your setup best.
Planting Beetroot Through Seedlings
You can begin sowing seeds in a greenhouse or indoors about 8-10 weeks before the expected date of the last frost. Check the first and last frost dates using your zip code on gardening websites.
Prepare the Soil
Use a light, neutral, or slightly acidic seed-starting mix, look for one with good drainage and a pH between 6.0 and 7.0. A ready-made option like Espoma Organic Seed Starter Mix works well and doesn’t need any adjusting before planting.
Choose a Tray for Planting Beets
Beets grow long roots early, so they need extra space even at the seedling stage. Most standard seed trays are too shallow, which can stunt their growth before you even transplant.
For beginners, a great all-around option is the Burpee SuperSeed Starting Tray. It has 16 extra-deep cells, good airflow, and a sturdy bottom tray to catch excess water. It’s reusable, easy to clean, and gives your beet seedlings enough room to grow strong roots from the start.
Sowing Beetroot Seeds
Fill each cell with seed-starting mix, pressing lightly to remove air pockets. Leave about ½ inch of space at the top so water doesn’t overflow. Lightly moisten the mix until it feels damp all the way through; not dry, not soaking.
Plant 1 to 3 beet seeds per cell, about ½ inch deep. Gently cover with soil and mist the surface to settle it. Keep the mix consistently moist while the seeds germinate. Drying out, even once, can slow or stop the process.
In 5 to 6 weeks, once the roots have filled the cells and your frost date has passed, the seedlings will be ready to move outside.
Transplanting Beet Seedlings
Transplant in the early morning or late afternoon to protect the seedlings from sun stress.
- Step 1: Prepare the Soil
Use well-loosened, nutrient-rich soil with good drainage, ideally the same type you used in your raised bed or growing mix. Water the area thoroughly before planting.
- Step 2: Remove the Seedlings Carefully
Use a flat tool such as a popsicle stick or a butter knife to gently lift each seedling from its cell. Do not pull by the stem and do not remove the soil around the roots. Try to keep the root ball intact and undisturbed.
- Step 3: Dig the Planting Holes
Make holes about 3 inches (7.5 cm) deep and 4 inches (10 cm) apart. For larger beet varieties, leave 20 inches (50 cm) between rows. Smaller varieties can be spaced a bit tighter.
- Step 4: Transplant and Firm the Soil
Place each seedling into a hole and gently press the soil around it so the roots make good contact. Don’t compact the soil, just press firmly enough to hold the plant upright.
- Step 5: Water Thoroughly
Water the seedlings again after transplanting. Use a watering can or hose with a gentle spray to avoid damaging the young plants.
Classic Direct Sowing of Beetroot
- Step 1: Prepare the Soil
Loosen the soil to a depth of at least 6 inches (15 cm). Remove rocks and clumps, and level the bed.
If you’re using old soil or planting directly in the ground, mix in compost and a balanced organic fertilizer with phosphorus, potassium, and a bit of boron.
If you’re using fresh bagged soil (like raised bed mix), you can skip this step; it’s already nutrient-rich.
Water thoroughly the day before planting so the soil is evenly moist but not muddy.
- Step 2: Make Furrows
Use a stick, trowel, or hoe to make furrows about 1 inch (2.5 cm) deep and 4 inches (10 cm) apart. For large beet varieties, leave 20 inches (50 cm) between rows. Smaller types can be planted closer together.
- Step 3: Sow the Seeds
Place beet seeds 1 to 2 inches (2.5–5 cm) apart in the furrows. No need to soak them, they’ll germinate just fine in moist soil. Cover the furrows with soil and press gently to ensure good contact.
- Step 4: Water
After planting, water the bed gently but thoroughly. Keep the top inch of soil consistently moist until the seedlings emerge.
- Step 5: Watch for Sprouts
Beet seeds usually germinate in 5–8 days if the soil is at least 50°F (10°C). In cooler soil, it may take up to 2–3 weeks.
Optional: Successive Sowing
To enjoy a steady supply of fresh beets, repeat the same process every 2–3 weeks until midsummer. Stop once daytime temperatures regularly exceed 75°F (24°C), as heat can cause beets to bolt or become woody.
How to Care for Beets While They Grow
Once your beets develop 4–6 true leaves, the focus shifts to steady growth and avoiding stress. Here’s what to do during this stage.
- Water regularly, but not too much.
Keep the soil moist down to the root level, but not waterlogged. Water early in the morning or later in the day to reduce evaporation. Always water at the base, not over the leaves, to lower the risk of disease. Inconsistent watering can cause beets to crack or grow unevenly.
Adjusting Watering in Late Summer
Reduce watering in the second half of the summer as the root crops mature to prevent the beets from cracking.
- Thin if needed.
If multiple seedlings came up in the same spot (which is common with beet seeds), thin them out by snipping the smaller ones at the base. You can gently transplant the strongest ones to empty spots if the roots aren’t too entangled.
- Keep weeds down and mulch in place.
Weeds compete for water and space, so pull them regularly. To make this easier, keep a layer of mulch around your plants — 2 to 3 inches (5–8 cm) of loose straw or compost is enough. It helps hold moisture, blocks weeds, and protects roots from heat. Don’t pile mulch right up against the stems, leave a small gap to prevent rot.
When is it Time to Harvest Beets?
- Harvesting Beet Leaves
Beet leaves are ready to be harvested when they are large enough for consumption. You can begin harvesting the leaves as the root crops continue to grow, but make sure that only the outermost leaves are cut. The central leaves are essential for the successful maturation of the crop.
- Harvesting Root Crops
Root crops can be harvested at any stage of their growth, and some gardeners specifically cultivate beets to harvest them while they are still small.
How to Tell When Beets Are Ready to Harvest
They’re ready when the roots look full, smooth, and about the size of a golf ball or larger — depending on the variety. Yellowing outer leaves are a good sign too. If the root is still bulky and the central tip is thick, give it more time.
How to Harvest and Store Beets
- Pick the right day.
Harvest on a dry day, as damp soil can shorten storage life.
- Pull gently.
In loose soil, grab the greens and pull. In heavy soil, loosen the root with a trowel first.
- Clean, don’t wash.
Brush off the dirt with your hands. Do not wash them, as moisture can lead to rot.
- Trim and dry.
Cut off the leaves, leaving 1 inch of stem. Snip long roots. Let them dry in the shade for a few hours.
- Store smart.
Store unwashed, trimmed beets in the fridge, ideally in the crisper drawer. Wrap each root loosely in a paper towel and place them in a breathable produce bag or container. This helps absorb moisture and keeps them fresh for up to 2–3 weeks. Check regularly and replace any damp paper towels.
Avoid plastic wrap, as it traps moisture and speeds up spoilage. Do not store beets near apples or bananas, since ethylene gas can make them taste bitter.
Problems When Growing Beets
| Problem | Description | Solution |
| Small roots | The plants stopped growing for several weeks. Often caused by poor soil, lack of moisture, or overcrowding. | Thin the plants if needed. Make sure the soil stays evenly moist. Spray with a liquid fertilizer that includes boron and potassium. |
| Brown spots on leaves | Usually caused by cercospora leaf spot — a fungal disease that appears in humid conditions. Starts on leaves and can spread to stems. | Use crop rotation to prevent it. Treat with a copper-based fungicide at the first sign. |
| Cracked roots | Caused by uneven watering or over-fertilizing with fresh manure. Roots split as they take up water too quickly after a dry spell. | Keep watering consistently. Avoid using fresh manure. Use boron-rich fertilizer to strengthen root tissues. |
| Light spots on leaves | May be rhizomania or ramularia, which appear in hot, humid weather. Can slow growth or damage foliage. | Treat with a general-purpose fungicide, especially one that includes copper. |
| Purple-gray coating on leaves | Signs of downy mildew (peronosporosis). Happens during warm, wet periods. Affects the leaves but not the roots. | Reduce watering and improve air flow. Spray with a phosphorus-potassium foliar feed and a copper-based fungicide. |
| Root rot | Fusarium rot usually shows up late in the season. Roots become soft and unusable. | Remove and discard affected plants. Avoid planting beets in the same spot next season. Improve soil drainage. |
| White rings inside the beet | Happens after long dry periods. The root develops unevenly, forming pale rings or streaks. | Water consistently throughout the growing season, especially during dry spells. |
Final Thoughts
The key to a successful beet harvest lies in planning. Start with good soil, use the right planting method, and keep the growing environment consistent. Don’t overcomplicate things; focus on watering, spacing, and proper care. By sticking to these simple steps, you’ll prevent issues like stunted growth and pests, and enjoy a steady supply of fresh, healthy beets.
