1. Space plants 12" apart in well-drained soil in full sun.
2. Water regularly, once or twice per week, or more often in extreme heat and less often in rainy weather.
3. Start spring plants in the ground early enough so they'll finish before the hottest part of summer.
4. Remove the outer two layers of hard, green flesh and eat the tender, white inside raw or cooked. Greens are also edible and can be harvested before the bulb as the plant matures. For long-term storage, chop the bulb and blanch the pieces for one minute before freezing for up to 12 months.
General Growing Tips For Your Seedling Tray
For best results with Kohlrabi Winner F1, plant one rooted liner per 4-inch container or 1801. Use a well-drained soil with a pH of 5.5-7.5, light feed (100-130 ppm N), and temperatures of 60-70 daytime and 40-50 nighttime. Don't pinch or use PGRs. You may see aphids and whiteflies. Watch for fungus and black rot.
Flowering
Kohlrabi is grown for its edible bulb and foliage. It is a biennial plant that produces a flowering stalk that goes to seed in its second year. However, in the vegetable garden it is typically harvested before it flowers.
Pinching
This plant doesn't require pinching.
Spacing
Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. Proper spacing helps prevent disease and control height.
Height Control
Provide adequate light and proper temperatures, fertilization, and water. These cultural controls will prevent Kohlrabi seedling plugs from stretching tall. We don't recommend using chemical growth regulators on vegetable seedlings.
Pests
The main pests that affect Kohlrabi Winner F1 are aphids and whiteflies. You may also see caterpillars and cutworms. We recommend using cultural controls for vegetable and herb crops as part of an Integrated Pest Management plan.
1. Aphids are small, pear-shaped insects that feed on plant sap, spreading diseases and causing leaves to wilt. Use insecticidal soap or neem oil to combat Aphid infestations. Beneficial insects like ladybugs, lacewings, and hoverflies will also help control the Aphid population.
2. Whiteflies are small, white insects that feed on the undersides of the leaves, reducing yields and causing leaves to turn yellow and wilt. Use sticky yellow cards or traps to monitor and combat the Whitefly population. Use insecticidal soap or neem oil as needed.
3. Caterpillars feed on plant foliage, causing significant damage. Handpick and dispose of them or use Bacillus thuringiensis (BT) to kill them.
4. Cutworms are caterpillars that feed on plant stems, causing them to wilt and die. Use cardboard collars to protect the stems or use BT to kill Cutworms.
Disease
Kohlrabi is susceptible to a few fungal diseases and Black rot. Practice prevention in your greenhouse with good sanitation, adequate airflow, proper irrigation, and an Integrated Pest Management program.
Clubroot is a soil-borne fungal disease that causes the roots to become swollen and distorted. It can lead to stunted growth and wilting of the plant.
Powdery mildew is a fungal disease that causes white growth on the leaves and stems, leading to yellowed wilting leaves and reduced yields.
Downy mildew is a fungal disease that causes yellow or brown spots on the leaves and can cause the plant to die.
Black rot is a bacterial disease that causes leaves to turn yellow and wilt, spreading rapidly through the plant.
Planting Kohlrabi Winner F1 Liners
We recommend planting one rooted plug per 4-inch container or 1801. Use well-drained soil and center the seedling in the container. Be gentle with the roots and water the seedling plug after transplant.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
