How to Germinate Cardamom – A Simple DIY Gardening Guide
- Start by preparing fresh cardamom seeds. Wash the seeds in lukewarm water to remove any mucilage. Allow cardamom seeds to dry in the shade.
- Place dried seeds in a glass jar and place the jar in a tray filled with cold tap water. Leave the jar in the cold water until the jar feels cold to the touch.
- Slowly pour a 2.5 percent nitric acid solution over the cardamom seeds, just enough to cover the seeds. Stir the seeds with a spoon for about 2 minutes. After the 2 minutes, drain the solution using a strainer.
- Now, take the seeds out into a strainer and rinse the seeds under running water.
- Transfer seeds to a bowl of lukewarm water and let sit overnight.
- Choose a site or a pot with well draining, moist soil, and filtered shade.
- After all danger of frost has passed, plant the cardamom seeds in a thin layer of soil.
- Spread a thin layer of seeds over the bed.
- Water the soil deeply until it feels moist.
- Cardamom should germinate anywhere from 20-40 days.
- Once germination starts, remove the twigs and just keep the soil moist.
- Depending on the variety you’ve planted, cardamom can be ready for harvest in the fall or the year after.
