Can You Plant Onions, Celery, and Apples Together?

Companion planting is a popular gardening technique where certain plants are grown together to enhance growth, deter pests, and maximize space. In this article, we explore whether onions, celery, and apples can be planted together. You’ll discover their compatibility, growing requirements, and practical tips to make the most of your vegetable and fruit garden.

Compatibility Analysis

YES, you can plant onions, celery, and apples together, but with some considerations. These plants can coexist due to their complementary growth habits and pest-repellent properties. Onions are known for their ability to repel pests, which can benefit both celery and apple trees. Celery, being a shallow-rooted plant, doesn’t compete aggressively for nutrients, making it a suitable companion for onions and apple trees. However, apples require more space and sunlight, so careful planning is necessary to ensure all plants thrive.

Key Factors:

• Growth Requirements: Onions and celery prefer cooler temperatures, while apple trees need full sun.
• Pest Control: Onions deter pests like aphids, which can affect both celery and apple trees.
• Nutrient Needs: Celery and onions have moderate nutrient needs, but apple trees require more nutrients.
