Tips for Successful Companion Planting with Garlic
- Spacing: Ensure proper spacing between garlic and its companion plants to avoid competition for nutrients and light. Garlic bulbs need about 4-6 inches of space on all sides.
- Soil Preparation: Garlic thrives in well-drained, nutrient-rich soil. Adding compost or well-rotted manure before planting can improve soil fertility.
- Watering: Keep the soil consistently moist but not waterlogged. Garlic prefers slightly dry conditions between waterings, especially as it matures.
- Mulching: Applying mulch around garlic plants helps retain moisture, suppress weeds, and protect the bulbs during colder months.
- Rotation: Avoid planting garlic in the same spot year after year to prevent soil-borne diseases. Rotate garlic with other crops to maintain soil health.
By choosing the right companion plants and following proper planting practices, you can create a thriving garden that benefits from the natural pest-repelling properties of garlic. Happy gardening!
