Mini Sweet Red Capsicum

Capsicum annuum (nightshade)

Also known as: Mini Sweet Red, Mini Sweet Capsicum

A compact, prolific little capsicum bred for snacking rather than cooking down. Short 40cm bushes crop heavily, covering themselves in mini red fruit that stay sweet whether picked young or left to fully ripen. Perfect straight off the plant for lunchboxes, or halved and stuffed for a quick platter. A great choice for pots and small garden beds where space is at a premium but a good capsicum harvest still matters.

Days to harvest 70-90 days
Fruit size Mini, red at maturity
Sowing depth 5mm
Germination 10–21 days at 22–28°C
Spacing 40–50cm apart
Aspect Full sun, well-drained soil
Frost tolerance Frost sensitive — needs reliably warm nights

Growing notes

Choose a full-sun spot with shelter from cold winds. The compact habit makes this one of the more forgiving capsicums for pots, raised beds, or tight garden spaces.

Soil preparation: Rich, well-drained soil with plenty of aged compost worked in — capsicums are hungry feeders, so don't skimp here.

Support: Generally not needed given the compact habit, but a light stake helps once the plant is loaded with fruit.

Watering & feeding: Water consistently — capsicums sulk and drop flowers if they dry out. Feed fortnightly with a balanced liquid fertiliser once flowering starts. Mulch to retain soil moisture.

Harvest: Pick regularly once fruit colours up to encourage more to set. Fruit can be eaten green but is sweetest left to ripen fully red. Cut rather than pull to avoid damaging the plant.

Timing: Expect first harvest around 70–90 days after transplanting. Continued cropping across the warm months with regular picking.

Key features

  • Heavy, prolific fruiting habit
  • Compact 40cm bush, ideal for pots and small spaces
  • Small, snackable red fruit
  • Sweet flavour even eaten straight off the bush
  • Great for kids' lunchboxes
  • Ideal for stuffing as bite-sized hors d'oeuvres

Short season tips


Best started indoors on heat mats — capsicums need 22–28°C soil to germinate. Sow 8–10 weeks before the last frost or purchase as 6–8-week-old seedlings. Transplant into the garden when soil temperature has reliably warmed to at least 15°C. Avoid disturbing roots when transplanting — capsicums resent being moved and stall easily. The compact habit makes this one easy to grow on in a pot and shift under cover if a late cold snap threatens, extending the usable season at inland NSW's cooler end.

Mini sweet capsicums are a modern type rather than an old heirloom line — the category was developed and commercialised from the 1990s onward, bred down from standard bell peppers to concentrate their sweetness and colour into a smaller, snackable fruit. Bell peppers themselves trace back to Capsicum annuum, domesticated in Mexico thousands of years ago and refined into the blocky "bell" shape by 19th and early 20th century American seedsmen. This mini type sits at the newer, smaller-fruited end of that long breeding line.
