How to grow a cardamom plant at home: Here's a step-by-step guide
Fragrant, flavorful, and prized in kitchens around the world, cardamom is not just a pantry staple it is a symbol of sophistication. And the good news is that even though it’s native to the rainforests of India and Sri Lanka, cardamom (Elettaria cardamomum) can thrive in home gardens with the right care.
While it requires a bit of patience and a humid environment, the rewards—fresh pods from your own plant—are well worth the effort. Whether you're cultivating a culinary herb garden or creating a lush green indoor space, here’s your step-by-step guide to growing cardamom from seed.
Get quality cardamom seeds
Start by sourcing high-quality cardamom seeds from a reliable nursery or supplier. Fresh seeds have a much better germination rate. If you’re using seeds from cardamom pods, ensure they’re green and not pre-dried or roasted, as those are often no longer viable for planting.
Choose the right containers
Use seedling trays or small pots with drainage holes. Biodegradable peat pots are also a great option, especially if you want to transplant the seedlings later without disturbing the roots.
Prepare the ideal potting mix
Cardamom seeds need a light, well-draining medium to germinate successfully. Mix equal parts of:
Peat moss (for moisture retention)
Perlite (to improve drainage)
Vermiculite (for aeration and lightness)
This mix prevents waterlogging and supports delicate root development.
Sow the seeds
Plant 2–3 seeds per pot, about ¼ to ½ inch deep in the potting mixture. Gently cover them with soil and lightly press down to ensure contact with the growing medium. Multiple seeds increase the chance of successful germination.
Creating a warm, humid environment
Cardamom thrives in warm, tropical climates. To mimic this, the plants need to be kept in temperatures between 70–80°F (21–27°C). Further, cover the pots with plastic wraps to trap humidity. It is also advisable to place the containers in a bright, indirect light spot or under grow lights as this greenhouse-like setup accelerates germination.
Moist but not soggy
Use a spray bottle or watering can to mist the surface regularly. Overwatering can lead to fungal growth and seed rot, so check for proper drainage.
Wait for germination patiently
Cardamom seeds are slow to sprout and can often take up to 2 to 4 weeks or longer. During this period, monitor moisture, maintain warmth, and avoid disturbing the soil. Once the true leaves appear (not the first two seed leaves), your seedlings are ready for the next step.
Transplant the seedlings
When the seedlings are about 3–4 inches tall and have at least 2 sets of leaves, gently move them to larger pots or into your garden. Choose a site with:
Partial shade (avoid direct midday sun)
Rich, well-draining soil that retains some moisture
Cardamom prefers a consistently moist but not waterlogged growing medium.
Feed the plant balanced fertilizers
Once established, ensure that the plants get a balanced liquid fertilizer or organic compost every 4–6 weeks to encourage lush, green foliage. Look for a fertilizer high in nitrogen, suitable for leafy herbs.
Maintaining and harvesting
Cardamom is a slow-growing perennial, and it may take 2–3 years before it begins producing pods. When pods ripen, harvest it when they turn green and plump. Then before storing them in an airtight container for usage ensure that they are dried enough.
