How To Sow
From seed to seedling
Soak seeds for 24 hours before sowing.
Nursery polybags or deep seedling trays.
Keep the soil medium moist.
Wait 2-4 weeks for germination.
Tending the Plant
Care through the season
Regular watering; increase frequency during fruit set.
Apply organic compost or citrus-specific manure every 6 months.
Monitor for leaf miners and citrus butterfly larvae.
Harvest fruits when they reach full size; the rind is most aromatic when the fruit is firm.

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.
Collect seeds from healthy, well-matured fruits.
Let the fruit stay on the tree until fully ripe.
Extract seeds, wash off the pulp, and dry in shade.
Store in a cool, dry place; citrus seeds lose viability quickly.
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.
