Growing Peppers: A Complete Profile
By GardenPlanner Team · July 17, 2026
Peppers are close cousins to tomatoes in care, but slower to get going and less forgiving of a cold snap — they genuinely stall out below about 55°F, where tomatoes just slow down. That’s why our planting calendar generally has peppers starting indoors even earlier than tomatoes.
What to expect
Peppers like it warmer and drier than tomatoes overall. Consistent moisture still matters, but soggy soil is more likely to cause problems for peppers than underwatering is. Fruit color is a maturity indicator, not a species one — most peppers are green when unripe and only turn red, orange, or yellow if left on the plant longer.
Common problems
Slow, stunted growth after transplanting is usually a temperature issue, not a soil one — peppers transplanted too early into cool soil can sit and sulk for weeks. Waiting an extra week or two past your tomato transplant date is often worth it.
Where this fits in your garden
Basil and onions are reputed companions — see the full companion planting guide for peppers. Peppers are heavy but slow feeders, so they pair well spatially with fast, light-feeding crops like lettuce filling in around them early in the season before the pepper plant fills out.
