Companion planting is the strategic placement of plants that support each other’s growth. This method is widely used in organic gardening to boost plant health, improve yields, repel pests, and enhance soil fertility.
Why Is Companion Planting Important?
✅ Pest Control – Some plants repel pests naturally, reducing the need for pesticides.
✅ Better Growth & Yield – Certain plants help others grow faster and stronger.
✅ Efficient Space Use – Maximizing garden space by planting compatible crops together.
✅ Improved Soil Health – Some plants enrich the soil with essential nutrients.
✅ Natural Pollination Boost – Attracting beneficial insects that help plants flourish.

2. The History and Science Behind Companion Planting 📜
Companion planting has been used for thousands of years, dating back to indigenous farming techniques like The Three Sisters method used by Native Americans.
The Three Sisters Method 🌽🌱🎃
The Three Sisters method is a perfect example of companion planting, where corn, beans, and squash are grown together:
Corn provides a natural trellis for beans to climb.
Beans enrich the soil by fixing nitrogen, benefiting both corn and squash.
Squash spreads across the ground, suppressing weeds and keeping the soil moist.
This symbiotic relationship demonstrates how plants can support each other’s growth when planted correctly.

3. How Companion Planting Works 🔬
Three Types of Companion Planting Relationships
1️⃣ Mutual Benefits – Both plants help each other (e.g., basil enhances tomato growth).
2️⃣ One-Sided Benefit – One plant benefits while the other remains unaffected (e.g., marigolds repel pests from nearby plants).
3️⃣ Pest Disruption – Certain plants confuse or deter pests, preventing infestations.
Companion planting is about understanding plant interactions and creating a balanced ecosystem in your garden.
