in Your Vegetable Garden
*** Easy To Grow ***
Kohlrabi looks something like a cross between a cabbage and a turnip, and tastes similar to a broccoli stem. This garden vegetable is known for the edible root, but the leaves are also edible. While it is somewhat similar to a turnip, growing kohlrabi provides a nice treat during hot summer weather when turnips struggle.
Kohlrabi contains: Chromium, Potassium, Dietar Fiber, Manganese, Thiamin, Folate, Magnesium, Phosphorus, Vitamin C, B6, Copper
Kohlrabi tolerates all gardening climates (from sub-zero to tropical). Growing Kohlrabi is most succesful in sunny, well-drained soil.
Kohlrabi will grow most fruitfully in soil that is rich in organic matter (compost, manure) and that is well-drained. Growing Kohlrabi requires a soil pH level of between 6.5 to 7.5. (Instructions: How to test your garden soil pH level.)
Unlike some other root crops, do not hill the soil around the vegetable as it grows.
Gardening Tip for Growing Kohlrabi - It has a shallow root system, so keep the garden bed free from competing weeds. (Remove weeds carefuly, such that you don't disturb kohlrabi's roots.)
Kohlrabi doesn’t normally tolerate transplanting, so it’s best to plant the seeds directly into your garden bed. Sow seeds from mid-summer to autumn. If you have a cooler gardening climate, you can also sow an additional crop in early spring.
Prepare the garden bed with an application of a complete fertilizer (mixed into the soil) a few weeks before you plant.
When the seedlings reach about 2" high, thin to about 6" apart.
When growing kohlrabi, it's important to keep the soil moist. If the soil dries out, the kohlrabi will likely be tough.
Boost growth by giving a dose of fertilizer (compost tea is my favorite) one month after planting.
Gardening Tip for Growing Kohlrabi - If you have sandy soil, you may want to apply a light fertilizer more frequently through the growing season.
When growing kohlrabi, you see: cabbage moth caterpillars, white butterfly, center grub, or downy mildew.
If you see leaves that are turning yellow, that most likely is telling you that there's a magnesium deficiency in the soil. If so, mix 1 oz Epsom salts with 5 quarts of water and water the ground around the plants with it.
Growing kohlrabi's requires between 8 and 10 weeks in growing season. Harvest once the vegetable root has reached 2 or 3 inches in diameter.
Gardening Tip for Growing Kohlrabi - Don't wait for the root to get bigger than 3", or it will be too tough.
Kohlrabi tends to go to seed when the temperatures drop below 60 degrees (F).
