Can You Plant Broccoli and Cauliflower Together?

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.

  • Broccoli and cauliflower must stay at least 3 feet (90 cm) apart to grow well.
  • As brassicas, they will compete for resources if spaced too close together.
  • Both plants are heavy feeders that benefit from regular fertilizer treatments.
  • Brassicas tend to attract the same pests, including cabbage loopers and aphids.
  • Adequate spacing and organic pesticides can help minimize insect infestations.

Cauliflower and broccoli also attract the same pests, like flea beetles, cabbage loopers, and aphids. Spacing them far apart helps minimize the infestation severity. Organic pesticides can help as well, especially when applied early and often.

What Grows Well Next to Broccoli?

Onions, rosemary, chamomile, lettuce, radishes, nasturtiums, marigolds, and beets are all good companion plants for broccoli. Beets, radishes, and lettuce grow well next to broccoli without taking its nutrients.

  • Your broccoli can benefit greatly from growing near certain companion plants.
  • Broccoli helps beets, lettuce, and radishes thrive without the fight for nutrients.
  • Marigolds and nasturtiums help keep cabbage loopers and other pests away.

For the best results, create a garden map on paper to work out the details before planting.

Broccoli and cauliflower are both challenging plants to grow well. They have heavy feeding needs, attract lots of pests, and are sensitive to environmental conditions.

  • Broccoli and cauliflower are not easy to grow, especially for beginners.
  • They are heavy feeders prone to attracting pests and sensitive to changing conditions.
  • The plants need full sun conditions with temps in the 40–70°F (4–21°C) range.

  • If you get any of the requirements wrong, your plants won’t produce a great harvest.

Both broccoli and cauliflower plants want to have full sun conditions. At the same time, they only thrive when it’s 40–70°F (4–21°C). Furthermore, they need sandy, well-draining soil that’s always slightly acidic. Get any of their conditions wrong and your plants won’t produce a good harvest.
