Plant Care
Yerba Mate grows best in warm, humid environments with a lot of light and moisture. It is a very slow growing plant at first but will pick up strength after a few years.Start with a healthy seedling or rooted cutting and plant in rich, well-drained soil. Mulch around the base to hold in moisture and keep roots cool. In its native climate, Yerba Mate can reach tree size, but it can also be pruned to remain shrub-sized in gardens or pots.
It takes years until the leaves are mature enough for harvest to make tea, but it's worth the wait; every single leaf comes with centuries-old tradition and vibrant taste.
Light
For the best growth and leaf development, place it in a place where it receives a minimum of 6 hours of sunlight daily. In extremely hot regions, some afternoon shade can help prevent leaf scorch, especially on young plants.
Soil
It thrives in well-draining soil that is slightly acidic and rich in nutrients. Between 5.5 and 6.5 is perfect. Gather compost or leaf mold and mix it in with your planting area to replicate the forest floor for this native plant. Avoid heavy clay or alkaline soils, which can hinder growth.
Watering
Yerba Mate needs constant moisture. The soil should be consistently moist, but never soggy. Water deeply whenever the top inch of soil feels dry, especially during hot or windy weather. If in containers, then it will likely require watering every few days. Reduce watering in winter when the plant is less active, especially indoors.
Pruning
Yerba Mate benefits from light, regular pruning to shape the plant and encourage denser foliage. Trim back leggy branches and dead or damaged growth. If you want to pick leaves to make tea, prune just after the flowering period—this encourages fresh, tender growth ideal for brewing.
Propagating
You can grow new Yerba Mate plants from seeds or cuttings:
- From seed: Seeds must be scarified, then soaked before planting. They require warmth and humidity to germinate, which takes a few weeks.
- From cuttings: Take semi-hardwood cuttings in late spring, dip in rooting hormone and plant in a moist, well-draining mix. Keep humid and warm until rooted.
Propagation is slow, but with patience, both methods can yield healthy new plants.
Growing in Pots
Yerba Mate adapts well to container growing, especially in cooler climates:
- Choose a deep pot (14–16 or deeper), with good drainage holes.
- Fill with acidic potting soil, enriched with peat or compost.
- Put it in a sunny spot and water frequently until the soil is evenly moist.
- Feed once a month throughout the growing season with a balanced, slow-release fertilizer.
Prune to maintain a manageable size and move indoors before cold weather if you're in a non-tropical zone.
Overwintering
In USDA plant hardiness areas 9 to 11, you can grow Yerba Mate outdoors all year around. In cooler zones, once temperatures are forecasted to drop below 45°F, move container plants indoors to a bright site, water only as needed, and refrain from fertilizing in preparation for winter dormancy. The plant will likely then grow very slowly or stop growing altogether until the return of spring.
Blooming
Yerba Mate blooms in late spring to early summer with small, white flowers that are pollinated by insects. While the blooms are modest and not the main attraction, they are essential for seed production. Mature plants (generally 4–5 years old) will be the only ones starting to regularly flower.
Common Issues
Yerba Mate is fairly resistant to pests and diseases but may experience some issues:
- Yellowing leaves may signal poor drainage or alkaline soil.
- Leaf drop often happens from cold drafts or inconsistent watering.
- Overly wet or compacted soil can cause root rot.
- Spider mites or scales may occasionally appear indoors; treat with insecticidal soap if needed.
Maintain good airflow, have a balanced watering, and acidic soil, and most issues will be prevented.
Summary
Yerba Mate is more than just a tea plant—it’s a cultural icon with deep roots and energizing benefits.
