CAPSICUM ‘Yolo Wonder’ Vegetable Seeds

‘Yolo Wonder’ is a classic open-pollinated bell capsicum known for its vigorous plants and high yields of large, blocky fruits. The thick-walled peppers are crisp, juicy, and mild in flavour, making them excellent for stuffing, roasting, grilling, stir-fries, or fresh salads. Fruits can be harvested green for a fresh flavour or left to ripen to bright red, when they become sweeter and richer in vitamins. This dependable variety is valued by home gardeners for its productivity, strong growth, and reliable performance.

Plant Type:

  • Warm season annual, frost tender
  • Plant Height: Typically 60–75 cm tall with sturdy branching plants

Sow When:

  • Germinate best between 20–25°C soil temperature
  • Temperate: Spring to early summer
  • Subtropical: Spring to early summer
  • Tropical: Spring to early summer
  • Arid: Early spring or late summer—sow in cooler periods to avoid heat stress
  • Cool Climate: Spring—start seeds indoors to extend the growing season

Germination:

  • Depth: Sow seeds 5 mm deep
  • Position: Full sun for best yields; partial shade tolerated in very hot climates
  • Sow Where: Start seeds indoors or in trays; transplant when seedlings have 4–6 true leaves and danger of frost has passed

Soil Type:

  • Details: Fertile, well-drained soil with a pH of 6.0–7.0; enrich soil with compost or aged manure before planting

Spacing:

  • Plant Spacing: 40–50 cm between plants
  • Row Spacing: 60–75 cm apart

Details:

  • Days to Harvest: 70–80 days after transplanting
  • Large, blocky bell peppers mature from green to bright red with thick, sweet flesh.

Growing Tips:

  • Maintain even soil moisture—capsicums prefer consistently moist but well-drained soil.
  • Mulch around plants to retain moisture and regulate soil temperature.
  • Apply a balanced fertiliser or liquid feed every 3–4 weeks during flowering and fruiting.
  • Stake plants if required to support heavy fruit loads.
  • Harvest regularly to encourage continued flowering and fruit production.
  • In cooler regions, start seeds indoors 6–8 weeks before the last frost and harden seedlings before transplanting.

Capsicum Growing Guide

Botanical name: Capsicum annuum

Capsicums are warm season, frost tender annuals to 60 – 90 cm tall; generally staking them is a good idea. Seeds germinate best at 20 – 30°C soil temperature. Sowing at too low a temperature will cause delayed or failed germination.

In Temperate Areas: sow in early spring – either inside with extra bottom heat by using a bottom heat propagator; behind a sunny window or on top of a hot water system; if sowing outside wait until all frost danger has passed and the soil is warm. Generally, if starting capsicum inside then sow seed 6 to 8 weeks before the last expected frost date in your area. By sowing early there will be time for a good crop to be produced before the first frost in winter.

In Subtropical Areas: sow March – October in frost-free areas; wait for spring in areas that receive frost.

In Tropical Areas: all year but avoid January – February above 32˚C can affect fruit set.

Soil Type: fertile, well drained, garden loam with a pH of 5.5 – 7.0; prepare the soil by adding compost. If stakes are required then put them at the same time as transplanting takes place to avoid later root disturbance. Providing support to keep fruit clear of the ground helps keep fruit clean and prevents slug and snail damage.

Germination period: 10 – 21 days (longer if the soil is cool); liquid feed the seedlings once germinated.

Planting depth: 6 mm deep
Position: full sun
Sow Where: into seedling pots to reduce transplant shock; transplant when the soil is warm
Plant Spacing: 40 – 50 cm between plants; 60 – 90 cm apart between rows
Details: keep well fertilised and watered; avoid high nitrogen fertilisers as these will promote leaf growth at the expense of fruit. In fruit fly areas the fruit should be protected by bagging
Harvest: 16 – 20 weeks: pick early fruit green to encourage fruiting
