Soil requirements
- Drainage matters. Peppers sitting in wet mix drop flowers and rot at the stem.
- They do not need an extremely rich bed. Excess nitrogen makes leaves at the expense of fruit.
- A 10–12 inch soil depth is usually enough in an open-bottom bed; go deeper in a closed planter.
Watering
- Less frequent than tomatoes once established, but do not drought them during flower and fruit set.
- Blossom drop in a heat wave is often temperature, not a fertilizer emergency. Night temperatures over about 75°F and day temperatures over about 90°F can abort flowers on many bells.
- Mulch to buffer raised-bed drying.
Sunlight
Full sun. In desert or extreme inland heat, light afternoon shade can reduce sunscald on fruit. Do not hide peppers behind tomato cages.
Planting
- Harden off transplants. Set them out when soil is near 60°F and frost is not a conversation anymore.
- Plant at the same depth as the container. Unlike tomatoes, peppers do not want a buried stem.
- A single stake prevents plants from snapping when loaded with bells.
Spacing
- Compact hot peppers: 12–14 inches.
- Standard bells and jalapeños: 14–18 inches.
- Large bell plants: 18–24 inches.
- Square-foot: usually 1 per square.
Common problems
Blossom drop
Common in temperature extremes or after a sudden shift from indoor to outdoor. Wait out the weather before over-fertilizing.
Aphids
Check undersides of leaves. A strong water spray and beneficial insects handle light pressure. Avoid broad insecticides that also kill pollinators.
Sunscald
White, papery patches on fruit. Maintain leaf cover; do not over-prune.
Slow start in cool soil
Raised beds help, but they cannot cancel a cold spring. Wait. Row cover can add a few degrees.
Helpful tools
- Stakes
- Mulch
- Soaker hose or watering can with a rose

Harvest
Bells can be picked green or left to color up; flavor sweetens as they ripen, and the plant’s total yield may drop if every fruit stays on until full color. Use pruners instead of tearing branches.
Frequently asked questions
Why are my pepper flowers falling off?
Heat, cold nights, or a dry-wet shock are the usual causes. Check soil moisture, then wait for milder weather before changing fertilizer.
Can I grow hot and sweet peppers together?
Yes. They will not make sweet peppers hot on the same plant. Cross-pollination affects seeds if you save them, not this year’s fruit flavor in any practical kitchen sense.
