This relationship is mutual because the beans benefit, too. The zucchini plant shades its root and prevents weeds from growing.

#2. Peas:

Bees are naturally attracted to borage making it an ideal companion plant to better pollination for your zucchini plants and better fruit yields.

By nature, zucchinis require a high level of ample pollination in order to form a large, healthy fruit.

And a healthy large fruit is very important if you don’t want to spend your free time outside with a paintbrush pollinating plants!

In addition to being a great plant to foster pollinator activity, borage is also good for mulching.

Borage emits calcium into the soil and calcium is a primary cause of blossom-end rot in squash fruits.

This is so because the mint crop will happily self-seed and take over your entire garden.
