Okay, I can definitely provide some information on kohlrabi companion planting.

When it comes to companion planting, it's important to consider which plants grow well together and which ones don't. Kohlrabi is a cool season crop that prefers to be planted in early spring or late summer/fall. Some good companion plants for kohlrabi include:

1. Cabbage: Since kohlrabi is related to cabbage, it makes sense that these two crops would do well together. They both prefer similar soil conditions and are susceptible to the same pests, so planting them together can help deter pests.

2. Carrots: Carrots and kohlrabi make great companions because they have different root depths, so they won't compete for nutrients in the soil. Additionally, carrots can help break up soil that may be compacted around the kohlrabi roots.

3. Beets: Similar to carrots, beets have different root depths than kohlrabi, so they won't compete for nutrients. Plus, they both like similar growing conditions and can help shade each other from the hot sun.

4. Lettuce: Planting lettuce around your kohlrabi can help provide some shade for the kohlrabi roots during hot weather. Additionally, since lettuce grows quickly, it can be harvested before the kohlrabi needs more space to grow.

5. Onions: Onions can help deter pests that may be attracted to kohlrabi. Plus, they're also a great companion for cabbage family crops like kohlrabi.

On the other hand, some plants that you should avoid planting near kohlrabi include:

1. Strawberries: Strawberries are susceptible to verticillium wilt, which can also infect kohlrabi.

2. Tomatoes: Tomatoes and kohlrabi are both heavy feeders, so planting them together can lead to competition for nutrients. Additionally, they both attract similar pests, like aphids.

3. Pole beans: Pole beans are nitrogen-fixing plants, which means they can deplete the soil of nitrogen that kohlrabi needs to grow properly.
