Growing Peppers: A Complete Profile
By Growing Home Greens Team · July 16, 2026
Peppers are close cousins to tomatoes in care, but slower to get going and less forgiving of a cold snap. They 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.
Warmer and drier than a tomato wants
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.
The transplant sulk
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.
A slow feeder that likes fast company
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.

Typically viable in USDA zones 3-11. Not sure your zone? Look it up by ZIP code.
Method: Start indoors: Start indoors from seed, then transplant outside. Pepper needs a head start most zones can't give it by direct-sowing alone.

How many Pepper plants fit per square foot?
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 1.5-3 ft.
Soil & water: pH 6-6.5. well-drained. Amend with lime if soil pH falls below 6.
Varieties worth considering
- Helios (F1) habanero: Reported by the breeder as earlier, higher-yielding, and with bigger fruit than standard habaneros, plus good yield potential in northern and short-season regions. (source)
- Carmen (F1): An AAS-winning Corno di Toro sweet pepper, early and adaptable at 60 days to green and 80 to full red, with a shapely tapered fruit and flavor that gets noticeably sweeter as it colors up. A good pick if you want a sweet frying pepper rather than another bell. (source)
- Flavorburst (F1): A true bell that starts lime green and ripens to golden yellow, bred by Johnny's for sweet flavor at that yellow stage rather than the more common green-to-red progression. Worth growing if you want a yellow bell without waiting on a slower heirloom. (source)
- 'California Wonder' (best for: classic stuffing bell): True Leaf Market lists this heirloom bell at 75-90 days, 4-5 inch blocky fruit with thick, crisp walls, the standard other bell peppers get compared against since the late 1920s. Open-pollinated, so it's the one to grow if you want to save seed rather than buying a hybrid like Flavorburst every year. (source)
- 'Bottle Rocket' cayenne (best for: hot, slim peppers): Johnny's lists this as a very-hot, early Thai-type cayenne, a different heat category entirely from the sweet varieties above. Grow it specifically if the goal is a hot, slim drying or hot-sauce pepper rather than a mild bell or frying type. (source)
