Save Your Own Seeds
One pack. A lifetime of harvests.
Because this is an open-pollinated heirloom — not a hybrid — every plant you grow can become next season’s seed source. Here’s how to keep the lineage alive.
Select healthy, fully mature seeds.
Collect mature capsules when they start to dry.
Extract marbled seeds from the prickly capsules.
Store in a cool, dark, dry place.
The truest gift of an heirloom seed is the seed it gives back. Save a few each season, share a few with neighbours — and you become part of a chain of gardeners stretching back generations. — From the Manvasanai farm journal

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.
