What should the light be for a Kohlrabi plant?
Kohlrabi plants require full sun to grow and thrive. This means that they should receive at least 6 hours of direct sunlight per day. The more sunlight the plant receives, the better it will grow and produce a larger bulb. If the plant does not receive enough sunlight, it may become stunted and the bulb may be smaller and less flavorful.
Kohlrabi can also tolerate some light shade, but it will not perform as well as it would in full sun. If you live in an area with very hot summers, it's a good idea to provide some afternoon shade to prevent the leaves from getting sunburned or wilting.
It's worth noting that while Kohlrabi can grow well in full sun, it can also grow well in cooler climates with lower light conditions, as long as they receive enough hours of daylight. This is because Kohlrabi is a cool-season crop and can tolerate temperatures below freezing point.
To ensure that your kohlrabi plants receive enough sunlight, choose a location in your garden that receives full sun for most of the day. Avoid planting kohlrabi in areas that are shaded by other plants or buildings. If you are growing kohlrabi in a container, make sure to choose a container that is large enough to accommodate the plant's root system and place it in a sunny spot.
In summary, Kohlrabi plants require full sun to grow and thrive, but they can tolerate some light shade. They should receive at least 6 hours of direct sunlight per day, and more sunlight will help the plant to grow and produce a larger bulb. If you live in a hot area, it's a good idea to provide some afternoon shade to prevent the leaves from getting sunburned or wilting.
What is the best soil type for a Kohlrabi plant?

How can a Kohlrabi plant be multiplied?
There are several ways to multiply kohlrabi plants:
Seed propagation: Kohlrabi is typically grown from seed, which can be sown directly in the garden or started indoors and then transplanted. Seeds should be sown in well-drained soil at a depth of about 1/4 inch and spaced about 2-3 inches apart. They should be kept moist and in a location with bright, indirect light until germination occurs.
Division: Kohlrabi plants can also be multiplied by dividing the root bulbs. This can be done in the fall or early spring before new growth begins. Carefully dig up the bulbs and divide them into smaller sections, making sure each section has at least one "eye" (a small bump on the bulb where new growth will emerge). Replant the divisions in well-drained soil and keep them well-watered.
Root cuttings: Another way to multiply kohlrabi plants is by taking root cuttings. This is done by cutting a 2-3 inch piece of root from the parent plant and planting it in soil. Keep the soil moist and in bright, indirect light until new growth appears.
Offsets: Kohlrabi also produce offsets, small bulbs that form at the base of the parent bulb. These can be carefully removed and planted in soil.
It's important to note that when propagating kohlrabi by seed, division, root cuttings or offsets, you should make sure that the parent plant is healthy and disease-free. Also, make sure that the soil is well-drained, and the planted areas are getting enough sunlight and water.
