Kohlrabi, a member of the cabbage family, is a unique vegetable known for its bulbous stem and mild, slightly sweet flavor. It’s becoming increasingly popular among gardeners in Texas due to its adaptability to a range of growing conditions and its nutritional benefits. In this comprehensive guide, we’ll explore everything you need to know about growing kohlrabi in Texas, including its ideal growing conditions, planting techniques, pest management, and harvesting tips.
Kohlrabi (Brassica oleracea var. gongylodes) thrives in cooler weather, making it an excellent choice for both spring and fall gardens in Texas. While it may not be as well-known as other brassicas such as broccoli or cauliflower, kohlrabi is packed with nutrients including vitamin C, potassium, and fiber. The edible part of the plant is its swollen stem, which can be enjoyed raw in salads, cooked like a vegetable, or even pickled for added flavor.
Texas features a diverse climate ranging from humid subtropical regions in the East to arid climates in the West. Kohlrabi grows best in cooler temperatures (60°F to 75°F), so timing your planting is crucial. In most parts of Texas, you can grow kohlrabi twice a year: once in early spring for a summer harvest and again in late summer for a fall harvest.
Kohlrabi prefers well-drained soil enriched with organic matter. The ideal soil pH for kohlrabi is between 6.0 and 7.0. Conducting a soil test before planting can help determine the nutrient content and pH levels of your garden soil. Amend the soil with compost or well-rotted manure to boost fertility and improve drainage.
Kohlrabi thrives in full sun but can tolerate partial shade. In Texas’ warmer areas, providing some afternoon shade can help prevent bolting (going to seed too early) during the hotter months.
Choose high-quality seeds from reputable suppliers. Look for varieties that are suited to your climate and have good resistance to diseases. Popular varieties include ‘White Vienna’, ‘Purple Vienna’, and ‘Grand Duke’.
Once your kohlrabi plants have established themselves, ensure they receive adequate care:
While kohlrabi is relatively hardy, it can still fall prey to common pests:
Regular monitoring will help catch any pest issues early before they become severe.
Timing is key when harvesting kohlrabi. Most varieties reach maturity within 55 to 70 days after planting.
Kohlrabi bulbs should be harvested when they are about 3–4 inches in diameter; at this size, they will be tender and flavorful. If left too long on the plant, the bulbs can become woody and tough.
Use a sharp knife or shears to cut the bulb off just above the soil line. Be careful not to damage surrounding plants if you are harvesting from a densely planted bed.
Freshly harvested kohlrabi can be stored in the refrigerator for up to two weeks when wrapped in plastic or placed in a perforated bag. Remove any leaves before storing as they can draw moisture away from the bulb.
In addition to being easy to grow, kohlrabi offers numerous health benefits:
