Compatibility Analysis

YES, onions, spinach, and raspberries can be planted together, but with some considerations. Each plant has unique growth requirements and characteristics that can complement one another when managed properly.

• Onions: Known for their pest-repelling properties, onions can help protect spinach and raspberries from common garden pests.
• Spinach: This leafy green thrives in the cool shade provided by taller plants like raspberries, making it a good undergrowth partner.
• Raspberries: These bushes can benefit from the pest-repelling qualities of onions and provide partial shade for spinach.

Key Factors

• Growth Requirements: Onions and spinach prefer cooler temperatures, while raspberries need full sun. However, spinach can tolerate some shade, making it adaptable.
• Pest Control: Onions can deter pests such as aphids and beetles, which can be beneficial for both spinach and raspberries.
• Nutrient Needs: All three plants have relatively similar soil nutrient requirements, but care should be taken to ensure adequate phosphorus and potassium levels, particularly for fruiting raspberries.
• Spacing: Adequate spacing is crucial to prevent overcrowding and allow each plant to access necessary resources.
