Beet
Beta Vulgaris
Beets, also known as beetroot or Swiss chard, are versatile root vegetables that thrive in cooler climates. They are prized for their vibrant color, nutritional value, and ability to enhance garden aesthetics. Growing beets is rewarding, offering both culinary and health benefits.
Everything it needs
9 essentials at a glance
Watering
Beets require consistent moisture, especially during germination and early growth.
Water them deeply once a week, providing about 1 inch of water. In hotter months, you may need to increase frequency to twice a week. Signs of over-watering include yellowing leaves and root rot, while under-watering can cause wilting and stunted growth.
Light
Beets thrive in full sun, needing at least 6-8 hours of direct sunlight daily.
They can tolerate partial shade, especially in hotter climates, but full sun is ideal for optimal growth and sweetness. Ensure they are placed in an area where they receive morning sun and some afternoon shade in extreme heat.
Soil
Beets prefer well-draining, loamy soil with a pH range of 6.0 to 7.0.
The soil should be rich in organic matter to promote healthy growth. A recommended potting mix is a blend of compost, peat moss, and perlite to ensure good drainage and nutrient availability.
Humidity
Beets prefer moderate humidity levels, around 40-60%.
To increase humidity, consider misting the plants or using a humidity tray. Signs of low humidity stress include leaf curling and browning edges, while excessive humidity can lead to fungal diseases.
Temperature
Beets grow best in temperatures between 50-75°F (10-24°C).
They are hardy in USDA hardiness zones 2-10, tolerating light frost but not extreme heat. In summer, they may bolt if temperatures exceed 80°F (27°C), so consider planting in early spring or late summer for fall harvest.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or similar.
Fertilize every 4-6 weeks during the growing season, starting when seedlings are 2 inches tall. Signs of nutrient deficiency include yellowing leaves and poor root development.
Pruning
Pruning is not typically required for beets, but thinning seedlings is essential to prevent overcrowding.
Use scissors to cut seedlings at the base, leaving the strongest plants spaced appropriately. Deadheading is not necessary.
Repotting
If growing in containers, repot when roots start to bulge above the soil surface or if the plant becomes root-bound.
Choose a pot that is at least 12 inches deep. To repot, gently remove the plant, loosen the roots, and place it in fresh potting mix, watering thoroughly afterward.
Propagation
Beets are typically propagated from seeds.
Sow seeds directly in the garden or pots 1/2 inch deep, spaced 2-4 inches apart, and thin seedlings to 3-4 inches apart once established. The best time to sow seeds is in early spring or late summer for a fall crop.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by nutrient deficiency, particularly nitrogen, or over-watering.
How to fix it
Ensure proper fertilization and adjust watering habits to maintain consistent moisture without waterlogging.
Root rot
Why it happens
Over-watering or poorly draining soil can lead to root rot.
How to fix it
Improve drainage by amending soil with perlite or sand and reduce watering frequency.
Bolting
Why it happens
Bolting occurs when plants flower prematurely due to stress from high temperatures or inconsistent watering.
How to fix it
Plant beets in cooler weather and maintain consistent moisture to prevent stress.
Pests (e.g., aphids, leaf miners)
Why it happens
Pests can infest beets, especially in warm, humid conditions.
How to fix it
Use insecticidal soap or neem oil to manage infestations and encourage beneficial insects.
Fungal diseases (e.g., downy mildew)
Why it happens
High humidity and poor air circulation can lead to fungal infections.
How to fix it
Ensure good spacing between plants, avoid overhead watering, and apply fungicides if necessary.
Care through the year
Spring
In spring, prepare the soil by tilling and adding compost. Sow beet seeds directly in the garden once the soil temperature reaches 50°F (10°C). Keep the soil consistently moist.
Summer
During summer, monitor moisture levels closely, especially in hot weather. Mulch around the plants to retain soil moisture and suppress weeds.
Fall
In fall, continue to water regularly and harvest beets before the first hard frost. Beets can be stored in a cool, dark place for several months.
Winter
In winter, if you live in a warmer climate, consider covering beets with mulch to protect them from frost. In colder regions, beets can be left in the ground until needed.
Toxicity & Safety
Beets are generally non-toxic to pets and children. However, excessive consumption of beet greens may cause digestive upset in some animals. Symptoms of ingestion include vomiting and diarrhea.
Good to know
Why are my beet leaves turning yellow?
Yellowing leaves on beets can indicate nutrient deficiencies, particularly nitrogen, or can be a sign of over-watering. Ensure you are fertilizing appropriately and maintaining consistent moisture.
How often should I water my beets?
Water beets deeply once a week, providing about 1 inch of water. In hotter months, you may need to increase frequency to twice a week to keep the soil consistently moist.
What is the best soil for growing beets?
Beets prefer well-draining, loamy soil with a pH of 6.0 to 7.0. A mix of compost, peat moss, and perlite is ideal for promoting healthy growth.
When is the best time to plant beets?
The best time to plant beets is in early spring or late summer for a fall harvest. They thrive in cooler temperatures and can tolerate light frost.
How do I prevent bolting in beets?
To prevent bolting, plant beets in cooler weather and maintain consistent moisture. Avoid planting during extreme heat to reduce stress on the plants.
Can I grow beets in containers?
Yes, beets can be successfully grown in containers as long as the pot is at least 12 inches deep. Ensure proper drainage and use a suitable potting mix.
