AmandaShare
Planning a vegetable and herb garden involves optimal plant placement, proper spacing, and companion planting to maximize yields, improve plant health, and reduce pest problems.
This guide covers:
✅ How to design an efficient garden layout
✅ Optimal plant placements and spacing
✅ Best companion plants & combinations to avoid
1. Designing an Efficient Vegetable & Herb Garden Layout
A well-planned garden maximizes space and ensures healthy plant growth.
A. Consider These Factors When Planning Your Garden
✅ Sunlight – Most vegetables and herbs need 6-8 hours of direct sunlight.
✅ Soil Quality – Ensure well-draining, nutrient-rich soil for best growth.
✅ Watering Needs – Place thirsty plants together to simplify watering.
✅ Plant Height – Tall plants (corn, tomatoes) should be placed north to avoid shading smaller plants.
✅ Companion Planting – Group plants that benefit each other while keeping incompatible plants apart.
✅ Crop Rotation – Change plant locations yearly to prevent soil nutrient depletion and pest buildup.
2. Vegetable & Herb Optimal Placements and Spacing
Proper spacing prevents overcrowding, improves airflow, and maximizes yield.

| Herb | Spacing Between Plants | Best Companion Plants | Avoid Planting Near |
|---|---|---|---|
| Basil 🌿 | 12 inches | Tomatoes, Peppers, Oregano | Rue |
| Cilantro 🌿 | 6 inches | Tomatoes, Peppers | Fennel |
| Mint 🍃 | 18 inches (container recommended) | Cabbage, Carrots | Parsley |
| Rosemary 🌿 | 12 inches | Beans, Carrots, Cabbage | Cucumbers, Basil |
| Thyme 🌿 | 12 inches | Cabbage, Tomatoes | None |
| Oregano 🌿 | 12 inches | Basil, Peppers, Tomatoes | None |

| Chives 🌿 | 6 inches | Carrots, Lettuce, Strawberries | Beans, Peas |
| Sage 🌿 | 12 inches | Cabbage, Carrots, Beans | Cucumbers |
3. Companion Planting: Best & Worst Plant Combinations
Companion planting improves growth, repels pests, and enhances flavor, while poor combinations can cause competition and disease.
A. Best Companion Plant Combinations
✅ "Three Sisters" Planting: Corn 🌽, Beans 🌱, and Squash 🎃 grow well together.
✅ Tomatoes + Basil 🌿: Basil repels pests and enhances tomato flavor.
✅ Carrots + Onions 🥕🧅: Onions deter carrot flies.
✅ Radishes + Lettuce 🥬: Radishes loosen the soil for lettuce roots.
✅ Peppers + Marigolds 🌼: Marigolds repel nematodes and pests.
B. Plants That Should Be Kept Apart
❌ Tomatoes & Potatoes – Both are prone to blight.
❌ Beans & Onions/Garlic – Onion family inhibits bean growth.
❌ Cabbage & Strawberries – Compete for nutrients.
❌ Carrots & Dill – Dill stunts carrot growth.
❌ Fennel & Almost Everything – Fennel inhibits most plants.
4. Step-by-Step Guide to Planning Your Garden Layout
Step 1: Choose the Right Garden Location
✅ Full Sun (6-8 hours daily) for fruiting vegetables (tomatoes, peppers, squash).
✅ Partial Sun (4-6 hours) for leafy greens (lettuce, spinach, kale).
✅ Shaded Areas for shade-tolerant herbs (mint, parsley).
Step 2: Prepare the Soil
- Test soil pH (Most vegetables prefer pH 6.0-7.0).
- Amend soil with compost to improve nutrients.
- Ensure proper drainage (raised beds for heavy clay soil).
Step 3: Plan for Companion Planting & Spacing
- Keep tall plants (corn, sunflowers) on the north side.
- Place bushier plants (tomatoes, peppers) in the middle.
- Low-growing plants (lettuce, radishes) go in the front.
Step 4: Install Plant Supports Before Planting
- Cages & Stakes for tomatoes, peppers, beans.
- Trellises for cucumbers, peas, climbing flowers.
Step 5: Use Mulch & Pathways
✅ Mulch reduces weeds and retains moisture.
✅ Pathways allow easy access for harvesting.
