Companion Planting Guide for Maximum Harvest

What is Companion Planting?

Companion planting is the practice of growing specific plants together to enhance growth, improve soil health, and protect against pests. Some plants naturally complement each other, while others can compete and stunt growth.

Benefits of Companion Planting:

✔ Pest Control – Certain plants repel harmful insects naturally.

✔ Improved Growth – Some plants provide nutrients that others need.

✔ Better Yields – Smart plant pairings lead to higher productivity.

✔ Natural Support – Tall plants can provide shade or support for smaller ones.

✔ Soil Health – Legumes, for example, enrich the soil with nitrogen.

Best Companion Planting Combinations for Maximum Harvest

Tomatoes + Basil + Marigolds

• Why? Basil enhances tomato flavor and repels pests like aphids.

• Marigolds deter nematodes and other harmful insects.

• Avoid planting with: Cabbage or potatoes (they compete for nutrients).

Carrots + Onions + Rosemary

• Why? Onions repel carrot flies, while rosemary enhances flavor.

• Good companions: Chives, leeks, and parsley.

• Avoid planting with: Dill (it can stunt carrot growth).

Corn + Beans + Squash (Three Sisters Method)

• Why? Corn provides support for beans, beans add nitrogen to the soil, and squash shades the ground to retain moisture.

• Great for small and large gardens due to vertical growing.

• Avoid planting with: Tomatoes (they compete for space and nutrients).

Lettuce + Radishes + Carrots

• Why? Lettuce provides shade for radishes and carrots, keeping soil cool.

• Radishes help break up soil, making it easier for carrots to grow.

• Avoid planting with: Parsnips (they attract similar pests).

Cucumbers + Nasturtiums + Dill

• Why? Nasturtiums attract beneficial insects that eat cucumber beetles.

• Dill improves cucumber growth and enhances their flavor.

• Avoid planting with: Potatoes (they can spread disease to cucumbers).

Peppers + Basil + Onions

• Why? Basil repels aphids and enhances pepper growth.

• Onions deter pests like spider mites.

• Avoid planting with: Fennel (it inhibits growth).

Plants That Should Never Be Planted Together

Some plants can hinder growth, attract pests, or deplete soil nutrients when grown next to each other. Here are some combinations to avoid:

❌ Tomatoes & Potatoes – Both are prone to the same blight diseases.

❌ Beans & Onions – Onions can stunt bean growth.

❌ Cabbage & Strawberries – Compete for nutrients and attract pests.

❌ Carrots & Dill – Dill can inhibit carrot root development.

Tips for Successful Companion Planting

• ✔ Plan Ahead: Design your garden layout with companion plants in mind.

• ✔ Rotate Crops: Prevent soil depletion and
