Care

Keep the soil consistently moist to ensure the roots develop properly without becoming woody. Watch for wilting leaves as a sign that the plant needs a drink. Thin your seedlings early so each beet has enough room to grow to its full size.

Watering: Keep the soil evenly moist but not waterlogged to prevent the roots from cracking.
Feeding: Apply a balanced, low nitrogen fertilizer once a month to encourage root development over leaf growth.
Pruning: Remove any yellowing or damaged outer leaves to keep the plant healthy and focused on root production.
Repotting: Beets are typically grown directly in the ground and do not require repotting.

Signs it needs repotting

Safety

People: The plant is generally safe to eat, though high consumption of leaves can be problematic due to high oxalate content.
Children: No specific risks, but keep an eye on small children around garden tools used for harvesting.
Contact allergens: Handling the foliage may cause mild skin irritation in sensitive individuals due to plant juices.
Airborne allergens: Pollen from the flowering stalks can trigger seasonal allergies in sensitive people.
Edibility: Beets contain oxalates which may contribute to kidney stones in sensitive individuals.

Growing it

Propagation: seed
When to plant: spring, late summer
Overwintering: In mild climates, mulch the soil to protect the roots. In cold climates, harvest all roots before the ground freezes.
In containers: Beets grow well in containers at least 30 cm deep to allow for root development.

Direct Sowing

1. Prepare loose, well draining soil.
2. Sow seeds 2 cm deep and 5 cm apart.
3. Keep soil consistently moist until germination.
4. Thin seedlings to 10 cm apart once they reach 5 cm tall.

Plant beets in rows between taller crops to maximize space in the vegetable garden.

Grows well with

Bush beans · Beans fix nitrogen in the soil which helps the beets grow.
Lettuce · These shallow rooted greens grow well alongside the deeper rooted beets.
Onion · Onions have a different root structure that does not compete for space.

Keep away from

Pole beans · Pole beans can shade out the beets and compete for nutrients.

Similar species

Swiss chard · It is the same species but bred specifically for its edible leaves.
