Compatibility Analysis

Can onions, spinach, and peaches be planted together? The short answer is: Yes, but with some considerations. While onions and spinach are excellent companions due to their similar growing requirements and mutual benefits, peaches require more attention due to their different needs.

Onions and Spinach

Onions and spinach complement each other well. Onions deter pests like aphids and certain beetles, which can harm spinach. Both plants enjoy full sun and well-drained soil, making them ideal companions in a vegetable garden.

Peaches

Peaches, being fruit trees, have different spacing and nutrient requirements. They need more space and deeper soil compared to onions and spinach. However, planting onions near peach trees can help repel pests like peach tree borers. Spinach can grow in the shade of peach trees, making use of otherwise unused space.
