Beets are a root crop with edible leaves. They grow well in the cool season, so are best planted in the fall or spring.
Cultural tips for growing beets, UC IPM
Planting
- Direct seed 4 to 6 inches apart in March to April or August to September; possibly in February, May, and October, depending on weather and local conditions.
- Transplant 4 to 6 inches apart in February to May or September to October; possibly June, depending on weather and local conditions.
- If growing your own seedlings, start the seeds 6 weeks before you want to plant.
- Beet “seeds” are actually a lumpy cluster of seeds. Since several seeds might germinate, it’s important to thin to a single seedling so that the plant can form its large root.
- When thinning, cut the stems of the excess seedlings rather than pulling, because pulling might damage the roots of the seedling you’re trying to keep. The thinnings can be eaten as greens.
Harvesting
- About 45 to 65 days in spring and summer, depending on the variety
- Begin harvesting when the roots are at least 1 inch wide, harvesting alternate plants to allow remaining plants to grow up to 3 inches wide.
- If left in the ground too long, beets may get tough or bolt (send up a seed stalk).
- Fall or winter plantings take longer to size up. They will hold well through the winter, but tend to bolt when the weather warms in the spring.
- Small leaves may be eaten in salads, and older leaves can be cooked as greens. When harvesting leaves, never take more than half.
- It’s common for the “shoulders” of beets to grow above soil level, and is not a problem.
Pest management
The most common pest for beets is leaf miner. The larvae leave silvery trails in the leaves. Young seedlings can be protected with row cover. Clip off and remove older, infested leaves.
