Seed Treatment Method
Prepare your seeds the traditional way
A simple ritual handed down through generations — gentle treatment that improves germination and protects young seedlings naturally.
Coriander seeds are actually fruits containing two seeds. Gently rub or crush the seeds to split them into two halves (mericarps) to double the germination points.

How To Sow
From seed to seedling
Split the seeds into two halves. Soak in water for 12 hours for faster germination.
Direct sow in pots or garden beds.
Mist lightly after sowing.
Wait 7-14 days for sprouts.
Tending the Plant
Care through the season
Water gently to avoid dislodging young seedlings.
Apply diluted vermicompost or seaweed extract every 15 days.
Watch for aphids; use organic neem spray if necessary.
Harvest leaves by cutting the outer stems first. For seeds, wait until the plant turns brown and dries.
Companion Planting
Plants that love this neighbour
Old wisdom and modern observation agree — these companions help your plant thrive, while a few are best kept apart.

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.
Allow a few healthy plants to flower (bolt) and set seeds.
Wait until the seed heads turn from green to brown.
Cut the stalks, place in a paper bag, and shake to release seeds.
Store in a cool, dry place in an airtight container.
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.
