How to Grow Cardamom: The Best Way to Grow Cardamom at Home

Cardamom (Elettaria cardamomum/cardamomo), a member of the ginger family, is prized for its seeds, a pungent, aromatic spice used worldwide. Native to the tropical rainforests of India, Myanmar, and Sri Lanka, this herbaceous perennial is a beautiful addition to any garden or home, provided you can replicate its natural environment.It is much easier to grow cardamom at home.

Understanding Cardamom’s Characteristics

Cardamom grows from thick, knobby underground rhizomes. These rhizomes produce an evergreen plant with erect, cane-like stems that can reach heights of 6 to 15 feet outdoors but only 2 to 4 feet indoors. The stems are adorned with glossy, dark green, lance-shaped leaves that can grow up to 24 inches long.

In late spring or summer, cardamom plants produce leafless flowering stems from their base. These stems bear 2-inch yellowish-white flowers, reminiscent of orchids, with lilac-purple veins and pink or yellow margins. While the flowers and stems are not scented, they give rise to pale yellowish-green fruit pods. Each 3/4-inch pod contains 15 to 20 aromatic seeds, commonly used in various culinary traditions, including Asian, Middle Eastern, and Scandinavian dishes and drinks.

 

How to Grow Cardamom:

Well, isn’t it the most common question that pops into everyone’s mind while using cardamom in the kitchen? “Can I grow cardamom at home? Is it possible to cultivate it in my garden or pots?” The answer is a resounding yes! Growing cardamom at home is not only possible but also incredibly rewarding.

To help elevate your home gardening game, we’ve put together a simple guide that will take you from planting seeds to harvesting your aromatic cardamom pods. Follow these steps and watch your gardening expertise soar to the next level.

When to Plant

Cardamom thrives in warm, tropical climates where temperatures rarely fall below 70 degrees Fahrenheit. If you live in a region with such conditions, plant cardamom outdoors when the temperature stabilizes above 70 degrees Fahrenheit. Cardamom should be gCardamomoors or moved indoors during the colder months in cooler climates.

Selecting a Plant Site

Choose a location in your garden that provides partial shade, as CardamomCardamomis is an understory plant that cannot tolerate direct sunlight. Ideal sites include edible gardens alongside other shade-tolerant plants or rain gardens where the soil remains moist. The soil should be rich, slightly acidic, and humus-filled, replicating the rainforest floor.

Spacing, Depth, and Support

If planting outdoors, space your cardamom seeds 1/2 to 1 inch apart and plant them about 1/8 inch deep. To allow sufficient space for growth and proper drainage, use containers at least 1 foot deep and 6 inches wide for potted plants. Young plants might need staking if they are in an area prone to heavy rains to prevent them from washing away.

Caring for Your Cardamom Plant

Light Requirements

Cardamom plants thrive in part to full shade. They should not be exposed to direct sunlight, which can scorch their leaves and hinder growth. To mimic their natural rainforest habitat, plant them under tall trees or provide shade with a garden canopy.

Soil Preferences

Cardamom is fertile, loam-based, and well-draining. Incorporate organic matter such as leaf mould or granulated bark to enhance soil fertility and moisture retention. Cardamom plants prefer slightly acidic soil, with a pH of 5.1 to 6.5.

Watering

Cardamom requires consistent moisture but not waterlogging. Mist the plants frequently with rainwater and ensure they receive regular watering. Stability is critical, as cardamom plants do not thrive in fluctuating soil moisture or climate conditions.

Temperature and Humidity

Cardamom needs a warm and humid environment. Optimal growth occurs when temperatures remain above 72 degrees Fahrenheit. The plant’s growth can suffer dramatically if temperatures drop below 50 degrees Fahrenheit. Consider growing Cardamom in a heated greenhouse or the most humid part of your home, such as a bathroom, in temperate or semi-tropical climates. While it may not flower or produce fruit indoors, Cardamom makes an attractive houseplant.

Fertilization

During the growing season, feed your cardamom plant with an organic, high-phosphorus fertilizer twice a month. Apply fertilizer after heavy rain, never before, to prevent nutrient washout. Supplementing with compost once a year can also boost soil fertility.

Pollination and Fruit Production

Cardamom plants rely on bees and other flying insects for pollination. In regions where these pollinators are scarce, hand pollination may be necessary. This involves using a small tool or brush to transfer pollen from the male anther to the female stigma. Timing is crucial, as cardamom flowers only stay open for about one day. Signs of successful fertilization include flower wilting and ovary swelling, which will eventually produce fruit pods.

Growing Cardamom in Pots

Cardamom grows well in pots, making it suitable for indoor gardening. Start by planting seeds in moist soil, spacing them at least 1 inch apart. Each plant will need a pot at least 1 foot deep and 6 inches wide. If multiple seeds are planted in a single pot, thin them out by keeping only the strongest seedling.

As cardamom plants can get stressed during transplanting, it’s best to choose a pot that can accommodate their total growth, typically 12 to 14 inches wide. Ensure the pot has ample drainage holes to prevent waterlogging.

Propagating Cardamom

Cardamom can be propagated by dividing the rhizome root structure or sowing seeds. To prevent the rhizome from overgrowing its container or plot, consider splitting it every three years.

To Divide Rhizomes:

Follow these steps to grow cardamom in your garden

1. Loosen the soil around the parent plant using a trowel and hand rake.

2. Lift the rhizomatous roots from the ground.

3. Use a sharp knife or root saw to separate a rhizome segment with at least four to five leaf shoots.

4. Plant the segment in a new location and replant the parent plant where it was.

5 usefull tips to Grow from Seed:

1. Purchase seeds specifically for planting or using seeds from a mature plant.

2. Allow the seed pods to dry on the plant, then break them open to collect the seeds.

3. Presoak the seeds overnight before planting.

4. Plant the seeds in a warm, partially shady spot with loamy, rich soil.

5. Expect germination to take about 30 to 40 days.

Overwintering Cardamom Plants

If your cardamom plant is kept outdoors during warm weather, bring it indoors when temperatures drop to 60 to 70 degrees Fahrenheit. Cardamom plants do not tolerate cold and will die if exposed to frost. During the colder months (October to March), withhold fertilizer and water only when the soil is dry. Keep the plant in the most humid part of your house, such as a bathroom, and provide filtered light. Mist the plant frequently to maintain humidity.

Common Pests and Diseases

Cardamom is generally pest-free but can occasionally be affected by thrips or cardamom mosaic virus. Aphids spread the virus, so it’s essential to control aphid populations. Use a forceful water spray, insecticidal soap, or neem oil to keep aphids at bay.

Harvesting and Storing Cardamom

Cardamom pods should be hand-picked when they begin to split or pull away easily from the plant. To store Cardamom prevent air and oxygen exposure by keeping it in airtight containers, such as jars with tight-fitting lids or vacuum-sealed bags. Store the containers in a cool and dry place, away from sunlight and heat to maintain freshness and potency.so it is very easy to grow cardamom in your garden.

Types of Cardamom

Cardamom has two main genus lines: Elettaria and Amomum, with Lanxangia being a less commonly cultivated genus.

Green Cardamom (Elettaria cardamomum): Also known as true CardamomCardamom, it is native from India to Malaysia and is commonly used in sweets.

Black Cardamom (Amomum subulatum): Native to Nepal and China, black Cardamom Has a more robust, smokier flavour and is used in savoury dishes like stews and curries.

Lanxangia Tsaoko (formerly Amomum Tsaoko): This type is native to China and Vietnam and is used in Sichuan cooking.

Green Cardamom vs. Black Cardamom

While both green and black Cardamom Are used for flavouring foods, they have distinct flavours and uses. Green Cardamom has a sweeter, eucalyptus-type flavour and is often used in desserts and sweet dishes. On the other hand, Black Cardamom has a smokier, more robust flavour with camphor or menthol notes, making it suitable for savoury stews and curries.

Historical and Cultural Significance

Cardamom ( cardamomo/ elaichi)  is the third, yes you are right.. The third most expensive spice by weight, just behind saffron and vanilla. Its trade and consumption history spans over 1,000 years. In the early 1900s, German coffee planter Oscar Majus Kloeffer introduced Cardamom to Guatemala. Until about 1980, India was Cardamom’s largest producer and exporter, but Guatemala has since taken the lead.

Cardamom is widely used around the globe. Middle Eastern countries often add it to warm beverages, while Scandinavian countries use it to flavour cookies and cakes.
