Growing Bell Peppers: A Complete Profile
By Growing Home Greens Team · July 16, 2026
Bell peppers are the blocky sweet peppers most people picture first. This profile covers the care every pepper shares; the other varieties, from cubanelle and shishito to habanero and rocoto, each have their own profile under Peppers on the plant list, with their own heat, timing and plant size.
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.
Mature height: 1.5-3 ft
Method: Start indoors: Start indoors from seed, then transplant outside. It needs a head start most zones can't give it by direct-sowing alone.

| Summer window | May–Jul | Jul–Sep | ~75 days after transplanting |
| 11a & 11bSummer window | Jun–Dec | Aug–Feb | ~75 days after transplanting |
Harvest dates are about 75 days after the sow or plant-out date, not after starting seeds indoors.

How many Bell 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. Needs well-drained soil. Amend with lime if soil pH falls below 6.
Good companions for bell pepper
- Basil: Reputed to repel aphids and improve pepper growth nearby, but a controlled garden trial testing this same claim on a related crop found no pest-reduction benefit from basil, and found higher pest counts on the basil-companioned plants: treat this pairing as unproven, not as a working pest deterrent.
- Onion: Reputed to deter many common pepper pests, though this specific pairing hasn't been tested the way onion/carrot pest-masking has: treat it as garden tradition.

Varieties worth considering
- 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) Buy seeds: High Mowing Organic Seeds
- 'California Wonder' (best for: saving your own seed): An older open-pollinated bell that, as a 2019 University of Georgia trial put it, remains popular particularly among amateur growers. Because it's open-pollinated, it's the one here you can save seed from. Expect less than the modern hybrids, though: in that trial's 2017 season its yield fell in the lowest group of 13 varieties, and the researchers note the name now covers two slightly different lines after years of genetic drift.
