You should not plant broccoli and cauliflower together. If you do, the plants fight for the same nutrients and attract lots of pests. Instead, put these plants at least 3 feet (90 cm) apart. Companion plants can go in between to serve as a beneficial buffer. Onions, chamomile, rosemary, lettuces, and radishes all thrive near both plants. Broccoli and cauliflower are both rather difficult to grow, especially for beginners. Cauliflower is definitely the most demanding of the two plants.
How Far Apart Do You Plant Broccoli and Cauliflower?
Space your broccoli and cauliflower plants at least 3 feet (90 cm) apart. The more space, the better really. These plants will fight for all the same nutrients since they’re both brassicas. They are heavy feeders, too. So, mix compost and aged manure into the soil before planting. Then, side dress with a balanced fertilizer throughout the growing season.
