In this guide, we will walk you through everything you need to know to successfully grow a yerba mate plant at home. Let’s get your new favorite plant started!
Key Takeaways
- Climate matters: The yerba mate plant thrives in warm, humid environments similar to its native South American home.
- Soil acidity is crucial: Your plant needs slightly acidic soil with a pH between 5.5 and 6.5 to absorb nutrients properly.
- Consistent moisture is key: Keep the soil evenly moist but never waterlogged to prevent root rot.
- Patience pays off: It takes about three to four years before a young yerba mate plant is mature enough for its first harvest.
- Pruning promotes bushiness: Regular trimming encourages a fuller plant, making it easier to harvest leaves indoors.
- Indoor growing is possible: If you live in a cold climate, growing the plant in a pot indoors with plenty of humidity works well.
- Proper drying is essential: Fresh leaves must be blanched and dried correctly to create the traditional mate tea.

Understanding the Yerba Mate Plant
Before you start planting, it helps to know what you are dealing with. The yerba mate plant, scientifically known as Ilex paraguariensis, is a species of holly native to South America. In the wild, it can grow into a massive tree reaching up to 50 feet tall. However, when you grow it at home, you can easily keep it pruned to a manageable shrub size.
What does it look like?
The plant features thick, dark green leaves with serrated edges. The leaves are the star of the show, as they are harvested to make the tea. During the spring, the plant produces small, greenish-white flowers. If pollinated, these flowers turn into tiny red berries. The overall appearance is lush and vibrant, making it an attractive houseplant even when you are not harvesting the leaves.
Choosing the Right Location and Climate
The yerba mate plant hails from the subtropical regions of Brazil, Argentina, and Paraguay. This means it loves warmth and humidity. If you live in USDA hardiness zones 9 through 11, you can grow your plant outdoors year-round. For everyone else, growing it in a container indoors is the best option.
Temperature requirements
This plant does not like the cold. Temperatures below 20°F (-6°C) can severely damage or kill the plant. Ideally, you want to keep it in an environment where the temperature stays between 60°F and 80°F. If you keep your plant outdoors during the summer, make sure to bring it inside well before the first frost of autumn.
Humidity is your best friend
Dry air is the enemy of the yerba mate plant. It thrives in high humidity, ideally around 60 to 80 percent. If you are growing it indoors, you will need to mimic this tropical environment. Just like a passion vine plant, yerba mate loves a humid atmosphere. You can increase humidity by placing a tray of pebbles and water near the plant, misting the leaves daily, or using a room humidifier.
Soil and Planting Requirements
Getting the soil right is one of the most important steps in growing a healthy yerba mate plant. This plant is very particular about its soil chemistry. It requires acidic soil to survive and thrive.
The perfect soil mix
You want a soil pH between 5.5 and 6.5. If your soil is too alkaline, the plant cannot absorb nutrients and will slowly die. To lower the pH, you can mix in peat moss, sulfur, or an acidifying fertilizer. A great potting mix for yerba mate consists of equal parts peat moss, perlite, and sand. This ensures the soil is acidic and drains well. Much like the pineapple guava plant, yerba mate hates having wet feet, so drainage is critical.
Planting your yerba mate
You can start your plant from seed or buy a small nursery plant. If starting from seed, be aware that germination is slow and can take several months. If you buy a young plant, choose a container that is at least 12 inches wide with drainage holes. Fill the pot with your acidic soil mix, place the plant in the center, and water it thoroughly.
Watering and Feeding Your Plant
Watering can be tricky. The yerba mate plant loves moisture, but it will quickly succumb to root rot if left sitting in water. You need to find the perfect balance.
How often to water
Stick your finger about an inch into the soil. If it feels dry, it is time to water. If it is still moist, wait a day or two. During the hot summer months, you may need to water every day. In the winter, the plant grows slower, so you can reduce watering. Always use room temperature water, as cold water can shock the roots.
Fertilizing for growth
Feed your yerba mate plant during the growing season, which is spring and summer. Use a liquid fertilizer designed for acid-loving plants, like azalea or camellia fertilizer. Dilute it to half strength and apply it once a month. Do not fertilize in the fall and winter when the plant is resting.
Pruning and Maintenance
If left alone, your yerba mate plant will grow tall and leggy. Pruning is essential to keep it bushy and manageable, especially if you are growing it indoors. A bushy plant also gives you more leaves to harvest!
How to prune
The best time to prune is in the spring before new growth begins. Use clean, sharp pruning shears to cut back the long stems. Always cut just above a leaf node to encourage new branches to form. Do not be afraid to cut back up to one-third of the plant. Similar to a pomegranate plant, yerba mate responds very well to a hard prune and will bounce back with vigorous new growth.
Pest control
Keep an eye out for common houseplant pests like spider mites, aphids, and scale. These pests love the humid environment that yerba mate provides. If you notice any bugs, wipe the leaves with a damp cloth or spray the plant with insecticidal soap. Keeping the leaves clean also helps the plant breathe and absorb light.
Harvesting Your Yerba Mate
This is the moment you have been waiting for! However, you must be patient. A young yerba mate plant needs time to establish a strong root system before you start taking its leaves.
When to harvest
Do not harvest any leaves during the first two years. In the third year, you can take a few leaves. By the fourth year, the plant is mature enough for a proper harvest. The best time to harvest is during the late spring or early summer when the leaves are at their peak.
How to process the leaves
You cannot just pick a leaf and brew it! Fresh leaves need to be processed. First, pick the leaves and small twigs. Next, blanch them by passing them briefly through hot water or steam. This stops the oxidation process. Finally, dry the leaves. You can dry them in the sun, in a dehydrator, or in a warm oven. Once they are completely dry and crumbly, they are ready to brew into a delicious, energizing tea.
Conclusion
Growing a yerba mate plant at home is a journey that requires patience and attention to detail. By providing the right acidic soil, plenty of humidity, and consistent moisture, you can keep this tropical beauty happy. Remember to protect it from the cold and prune it regularly to maintain a bushy shape. Before you know it, you will be sipping your very own homegrown yerba mate tea. Happy planting!

Is the yerba mate plant frost-tolerant?
No, the yerba mate plant is not frost-tolerant at all. It is a subtropical plant that can be damaged by temperatures below 25°F and killed by prolonged freezing temperatures. If you live in a cold climate, keep it in a pot and bring it inside during the winter.
Can I grow yerba mate from store-bought seeds?
Yes, but it requires patience. Yerba mate seeds have a very hard outer shell and can take several months to germinate. You will need to scarify the seeds by gently scratching the outer shell before planting them in warm, moist soil.
