Companion plants for broccoli can be defined as close plantings of different species based on their ability to enhance each other’s growth or provide some form of pest protection or another advantage.

Sometimes this is the selection of plants with different growth habits that do not compete with each other or those that have different nutritional needs and make efficient use of the soil.

Strategic companion planting is especially important in small gardens or where careful space planning is required.

Reasons why you should grow broccoli
Broccoli (Brassica oleracea) is a member of the cabbage family, along with cauliflower, hugger kale, and collard greens.

It is an excellent plant because not only is it one of the most nutritious of all vegetables, but also easy to maintain.

A cool-season vegetable, broccoli fully matures in only 6 to 8 weeks and can then be removed to make room for summer/fall crops.

Or, in areas where frost is coming, you can plant the fall crop again.

Broccoli does not like temperatures above 75°F, so midsummer is not the time for the broccoli.

Although it likes full sun, broccoli is one of the few vegetables that can produce properly in partial shades.

Its soil needs are fairly low-key: both in sandy and clay-rich soils – and everything in between.

All in all, broccoli is one of the more suitable vegetables you can grow.

Broccoli can also planting with others vagetable and it rarely gets in the way of other growth.

The exception is plants that require very heavy calcium, as broccoli consumes a lot of calcium from the soil (which is one of the things that makes broccoli a good healthy food).

Broccoli growers may want to consider bone meal or another calcium-rich soil amendment that is growing broccoli.

Potatoes have a negative impact on many vegetables, but not broccoli, which does not seem to be affected by proximity to potatoes.

In general, it is best to mix broccoli with plants that do not require much space and are most robust in late spring and early summer.

Plants that fit into this category include loose-leaf lettuce, spinach, Swiss chard, and radishes.

Other than that, the list of good neighbors for broccoli is a big one. (Note: These suggestions also apply to Brussels sprouts, a close relative of broccoli.)
