Mimulus Magic™ Grow Guide for South Africa

Mimulus Magic™ Mix brings bright colour to pots, baskets and sheltered border edges. Sow pelleted seed well, keep young plants evenly moist and choose a cool-season window for your area.

Quick grow facts

• Scope: Mimulus Magic™ Mix F1, pelleted seed.
• Botanical name:Mimulus × hybridus; synonym Erythranthe × hybrida.
• Growth form: Compact spreading annual, 20–25 cm high and wide.
• Position: Bright partial shade; morning sun and afternoon shade in warm districts.
• Sowing depth: Surface sow; do not cover pellets.
• Germination: 18–20°C, about 5–7 days.
• Flowering: Magic is a long-day series. Under short days, controlled production extends the light period to 14 hours during young-plant growth. Plants already raised with 14-hour days do not need continued day extension after transplanting; short-day-raised plants may need long-day conditions later before flowering. This flowering signal is separate from germination light.
• Spacing: 20–25 cm in beds; 15–20 cm in containers with airflow.

Sowing and transplanting

Fill clean cells with free-draining seedling mix and water first. Place one pellet on the surface; mist or bottom-water so pellets stay consistently moist until they dissolve. Keep trays at 18–20°C in bright indirect light. Do not soak, chip or pre-treat pellets. Transplant after true leaves develop, harden off, then plant into humus-rich, well-drained soil. Keep soil evenly moist, feed lightly with a balanced liquid fertiliser after establishment and remove spent flowers.

Wash hands after handling seed and keep seed away from children, pets and food-preparation surfaces. This is an ornamental plant: do not treat flowers or foliage as edible.

Regional timing

Winter-rainfall Western Cape

Choose cool growing conditions while allowing for the long days needed for flowering. An autumn sowing under short days may establish without flowering on schedule; protect from waterlogging and late frost.

Frost-prone interior

Start protected trays in late winter to early spring and plant after hard frost. Late-summer sowing is an option for establishment, but autumn colour depends on the plants receiving suitable long-day conditions.

Humid coast and KZN Midlands

Use cooler weather with morning sun, afternoon shade and generous airflow. Allow for flowering day length as well as temperature; short-day growth alone does not promise a timely flower display.

Hot-dry or subtropical interior

Sow in cooler weather or use a shaded container; shield from hot afternoon sun and drying wind. Flowering also depends on long days, so a cool short-day sowing may not give colour on schedule.

Pests, diseases and troubleshooting

Check for aphids, whiteflies and thrips. Start with a firm water spray or hand removal where appropriate, and use only registered products as labelled. Prevent botrytis and root rots with clean media, drainage, airflow and soil-level watering.

• No germination: pellets may have dried out, been covered, or been too cold/hot. Re-sow on a moist surface at 18–20°C.
• Weak seedlings: improve bright indirect light and airflow.
• Bud drop: give morning sun, afternoon shade and even moisture.
• Yellowing or collapse: improve drainage and use clean, free-draining mix.
