Choosing Companion Plants for Your Chilli Pepper Patch

Selecting the right companion plants can significantly enhance your pepper harvest. Here are some key factors to consider:

  • Sunlight Needs: Peppers thrive in full sun, so avoid companions that cast too much shade. Taller plants like corn should be placed strategically on the north side of your peppers to provide afternoon shade without blocking morning sun.
  • Mature Size: Consider how big each plant will get at maturity. Low-growing herbs like oregano and chives won’t compete with peppers for sunlight, while larger companions like sunflowers need to be planted further away to prevent crowding.
  • Planting Distance: For most herbs, a spacing of 6-8 inches around the base of pepper plants is sufficient. Bush beans and peas can be planted closer, around 4-6 inches away. Taller companions like corn should be planted at least 18 inches from peppers.

Tools You May Need For Companion Planting:

  • Gardening gloves to protect your hands while planting.
  • Hand trowel for digging holes for transplants and mixing soil amendments.
  • Garden rake for leveling soil and smoothing planting beds.
  • Seed spreader (optional): A handheld seed spreader can be helpful for sowing small seeds like those of carrots or herbs.
  • Watering can or hose for watering your plants.
