Troubleshooting

Seeds are not germinating after several weeks.

Ensure consistent warmth (15-20°C) and adequate moisture. Patience is key, as germination can take up to 4 months. Consider trying a different batch of seeds if problems persist.

Seedlings are leggy and weak.

Provide more light. Ensure seedlings are not overcrowded and are in a well-draining medium. Avoid overwatering.

Plants fail to establish outdoors.

Ensure proper acclimatization to outdoor conditions before planting. Check that the soil is well-drained and the planting location receives adequate sun or partial shade as required.

Plants rot at the base.

This indicates poor drainage. Replant in a location with better-drained soil or amend the soil with grit. Avoid overwatering.

Poor flowering or small blooms.

Ensure plants are receiving adequate sunlight and are not competing with aggressive weeds or other plants for nutrients. Regular deadheading can encourage more blooms.
