How we grow & harvest these seeds
Storage & shelf life
Common growing challenges
- Poor germination? Most often a result of cold soil, irregular watering, or seeds buried too deep. Soak before sowing, sow at the recommended depth, and keep soil consistently moist.
- Yellowing leaves? Usually a sign of waterlogging or nitrogen deficiency. Improve drainage and apply a compost tea drench.
- Pest attacks? Switch to weekly preventive sprays of neem oil + diluted soap solution. Encourage ladybugs and birds in your garden.
- No flowering? Often too much shade or excess nitrogen. Move to fuller sun and reduce nitrogen-heavy feeds.
