Compatibility Analysis

Can you plant corn, dill, and fennel together? The short answer is no. While corn and dill can be beneficial companions, fennel is generally not recommended to be planted with either.

Why Corn and Dill Work Together

• Pest Control: Dill attracts beneficial insects like ladybugs and parasitic wasps, which help control aphid populations that can harm corn.
• Growth Requirements: Both plants thrive in full sun and well-drained soil, making them compatible in terms of environmental needs.

Why Fennel Is Not Compatible

• Allelopathic Effects: Fennel releases compounds that can inhibit the growth of many plants, including dill and corn.
• Nutrient Competition: Fennel’s robust growth can outcompete nearby plants for nutrients and space.
