Growing Tips

  • Peppers need warm soil โ€” wait until soil is consistently above 65ยฐF before transplanting.
  • Use black plastic mulch to warm the soil and retain moisture.
  • Pinch off the first set of flowers to encourage the plant to put energy into growing bigger first.
  • Water deeply but infrequently โ€” peppers don't like wet feet.
  • Sweet and hot peppers can cross-pollinate. Keep them 300+ feet apart if saving seeds.

Common Mistakes

  • Transplanting too early โ€” peppers are more cold-sensitive than tomatoes.
  • Overwatering, especially in cool weather, leads to root rot.
  • Not staking tall varieties โ€” heavy fruit load can snap branches.
  • Picking fruit before it's fully ripe โ€” let it change color for better flavor.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
