Frequently asked growing questions

How long does it take kohlrabi to grow?

White Vienna is commonly described as about a 60-day crop by Utah State University Extension. Actual timing changes with soil temperature, weather, thinning and harvest size; use the plant's swollen stem as the harvest cue, not a fixed date.

Does kohlrabi grow underground?

No. The edible round portion is a swollen stem that forms above the soil line. The roots grow below it. Kohlrabi is not a turnip root.

How many kohlrabi do you get off of one plant?

Normally one edible enlarged stem per plant. Sow several plants in small batches if you want more than one harvest window.

Can I plant kohlrabi in July?

In some locations, yes. Mid-summer planting can suit a fall crop when seedlings can establish and the enlarged stem will mature in cool weather. Adjust timing to local frost and heat conditions.

How do you know when kohlrabi is ready to be picked?

Most standard types are harvested with a firm, rounded stem about 2–3 inches wide. Letting typical varieties become much larger can make them woody or fibrous; follow the packet for variety-specific exceptions.

What type of fertilizer should I use for kohlrabi plants?

Start with fertile, well-drained soil and a soil test. Apply finished compost or a balanced vegetable fertilizer only as needed, following its label. Heavy nitrogen is not a substitute for correct spacing and moisture.

What is the difference between turnips and kohlrabi?

Kohlrabi forms a swollen stem above ground, while a turnip forms a storage root below ground. Both prefer cool-season conditions, but they are different crops.

Can kohlrabi be eaten raw or cooked?

The harvested vegetable can be peeled and served raw, steamed, roasted or stir-fried. This listing sells seeds for planting, not ready-to-eat kohlrabi or edible sprouts.

How to sow and harvest kohlrabi

1. Choose a cool growing window. Sow in early spring, or plan a fall crop that develops as temperatures ease. Use your local planting calendar for exact timing.
2. Plant shallowly. Sow about 1/4–1/2 inch deep in fertile, well-drained soil, keeping the seedbed evenly moist.
3. Thin promptly. For typical varieties, leave roughly 4–6 inches between plants; check the packet and local guidance for final spacing.
4. Maintain even growth. Give plants adequate sunlight, keep weeds down, water consistently and watch for cabbage-family pests.
5. Pick while tender. Standard kohlrabi is often best when the swollen stem is approximately 2–3 inches across. Cut it below the globe and prepare the vegetable after harvest.
