What is companion planting?

basically, it is the idea of planting certain plants together so they can benefit from one another.


Companion Planting


Companion planting is the process of planting specific plants together so a certain quality of one plant may be of benefit to another. The smell of a plant's foliage or the taste of a plant may be all that is necessary to discourage some insects. Some plants make great companions in that they encourage insects for pollination, provide shelter or support, or they simply grow well together because their roots are at different levels. Some plants are great companions as they may "disguise" the legginess of other plants or they help cool the soil for plants that require cool roots.

In the perennial flower garden, chives planted under roses may reduce the occurrence of black spot as well as discourage aphids.

Indicated below are some companion plants for the vegetable garden:
