Troubleshooting
Seeds not germinating
Ensure seeds are fresh and have been kept in appropriate conditions. Try soaking seeds overnight before sowing or using the moist kitchen roll method to check for viability. Ensure soil is consistently moist but not waterlogged.
Seedlings are leggy and weak
Provide more light. If growing indoors, move them to a brighter windowsill or use grow lights. Ensure they are not kept too warm before planting out. Pinching out the tips once they reach 7-10cm can encourage stronger, bushier growth.
No flowers or very few blooms
Ensure plants are receiving adequate sunlight (at least 6 hours per day). Regular feeding with a balanced liquid fertilizer and consistent watering can promote flowering. Pinching out tips encourages more flower production.
Pests on seedlings or plants
Inspect plants regularly for common pests like aphids. Use a mild insecticidal soap or a strong jet of water to dislodge them. Encourage beneficial insects in the garden.
Plants are not climbing
Ensure the support structure is in place before plants get too large. Gently guide young tendrils towards the support. Adequate sunlight and water are also necessary for healthy growth.
