Can You Plant Onions, Apples, and Geraniums Together?

Companion planting is a popular gardening strategy that involves growing different plants together to enhance growth, deter pests, and improve yields. This article explores the compatibility of planting onions, apples, and geraniums together, offering insights into their growth requirements and benefits.

Compatibility Analysis

The straightforward answer to whether you can plant onions, apples, and geraniums together is: Yes, but with caution. While these plants can coexist, they have different growth needs that require careful consideration. Onions are known for their pest-repelling properties, which can benefit apple trees by deterring pests like aphids. Geraniums, on the other hand, are attractive to pollinators and can add aesthetic value to the garden. However, the key factors to consider include their different sunlight, water, and nutrient needs, as well as spacing requirements to ensure each plant thrives.
