FAQs

When is the best time to sow these seeds?

Sow indoors between February and April for the best results.

Can these peppers be grown in pots?

Yes, with a final plant height of 750 mm, they are well-suited to large pots or garden beds.

Do I need to harden off the plants before putting them outside?

Yes, ensure you plant them out in May only when temperatures are consistently at least 15°C.

What should I cover the seeds with?

Use a fine layer of vermiculite over the seeds after sowing them 1/2 cm deep.

How long will the harvest last?

These peppers typically produce fruit for harvesting from July through October.

Troubleshooting

Seedlings appear tall and spindly (leggy)

Increase ventilation and reduce the ambient temperature to 14°C to slow upward growth and encourage stem strength.

Poor germination rates

Ensure the temperature is held at a consistent 18°C and the compost remains moist but not saturated.

Plants failing to fruit or fruit is small

Check that the plants are receiving consistent water and ensure you are applying liquid fertilizer weekly once fruit swelling begins.
