When planning your garden, it is important to consider crop rotation to maintain soil health and prevent the buildup of pests and diseases. This means avoiding planting certain crops near each other, including kohlrabi. Kohlrabi should not be planted near other members of the Brassica family, also known as cruciferous vegetables. These include broccoli, cauliflower, collards, kale, turnip, rutabaga, cabbage, mustard, bok choy, and Brussels sprouts.
The reason for avoiding planting kohlrabi near these crops is that they are all susceptible to similar pests and diseases. By rotating your crops and avoiding planting them in the same area for at least four years, you can reduce the likelihood of pest infestations and disease outbreaks. This practice helps break the life cycle of pests and pathogens that may have overwintered in the soil.
Personally, I have experienced the consequences of not practicing crop rotation. In one season, I planted kohlrabi near cabbage, and both crops suffered from a severe infestation of cabbage worms. These pests quickly spread from one plant to another, causing extensive damage. Since then, I have learned the importance of rotating crops and avoiding planting related vegetables near each other.
To make it easier to remember which crops to avoid planting near kohlrabi, I recommend creating a crop rotation plan. This plan can be as simple as dividing your garden into sections or beds and rotating crops within each section each year. By keeping track of which crops were planted in each section, you can ensure that kohlrabi is not planted near its relatives.
In addition to crop rotation, it is also beneficial to practice good garden hygiene. This includes removing any plant debris after harvest, as it can harbor pests and diseases. Regularly inspect your kohlrabi plants for signs of pests or diseases, and promptly address any issues that arise. By taking these preventative measures, you can help ensure the health and success of your kohlrabi crop.

Crop rotation is essential to maintain soil health and prevent the buildup of pests and diseases. By avoiding planting related vegetables near each other and practicing good garden hygiene, you can increase the chances of a successful kohlrabi harvest.
