Maca, or Lepidium Meyenii, is a unique root vegetable native to the Andes mountains of Peru. Known for its nutritional benefits and adaptability, it is increasingly popular among health enthusiasts and gardeners alike.
Everything it needs
9 essentials at a glance
Watering
Lepidium Meyenii, commonly known as Maca, prefers moderate watering.
Water the plant every 1-2 weeks, allowing the top inch of soil to dry out between waterings. In the growing season (spring and summer), increase frequency to once a week. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
Maca thrives in full sun but can tolerate partial shade.
Ideally, it should receive 6-8 hours of direct sunlight daily. If grown indoors, place it near a south-facing window. Too much shade can lead to leggy growth, while excessive direct sunlight can scorch the leaves.
Soil
Maca prefers well-draining, sandy loam soil with a pH range of 6.0 to 7.0.
The soil should be rich in organic matter to support its growth. A recommended potting mix includes equal parts of potting soil, sand, and perlite to ensure adequate drainage.
Humidity
Maca prefers moderate humidity levels, around 40-60%.
To increase humidity, consider using a humidity tray or a room humidifier. Conversely, if the environment is too humid, ensure proper air circulation to prevent fungal diseases. Signs of humidity stress include browning leaf tips and wilting.
Temperature
Maca grows best in temperatures between 60-75°F (15-24°C).
It is hardy in USDA zones 7-10. While it can tolerate cooler temperatures down to 50°F (10°C), prolonged exposure to frost can damage the plant. In hotter climates, provide some afternoon shade to prevent heat stress.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10.
Fertilize every 4-6 weeks during the growing season, reducing frequency in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth, indicating the need for additional feeding.
Pruning
Pruning is not typically necessary for Maca, but removing dead or yellowing leaves can promote better air circulation.
Use clean, sharp scissors or pruning shears. If the plant becomes too leggy, you can trim back the stems to encourage bushier growth.
Repotting
Repot Maca every 2-3 years or when it outgrows its container, typically when roots start to emerge from the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. Carefully remove the plant from its pot, loosen the roots, and place it in fresh potting mix. Water thoroughly after repotting.
Propagation
Maca can be propagated through seeds.
Sow seeds in spring after the last frost, spacing them about 12 inches apart. Cover lightly with soil and keep the soil moist until germination, which typically occurs within 2-3 weeks. Thin seedlings to ensure proper spacing once they reach a few inches tall.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Reduce watering frequency and ensure the plant is in well-draining soil. If nutrient deficiency is suspected, apply a balanced fertilizer.
Wilting
Why it happens
Under-watering or extreme heat.
How to fix it
Check the soil moisture and water if dry. If in extreme heat, provide shade during the hottest part of the day.
Leggy growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location to ensure it receives adequate sunlight.
Root rot
Why it happens
Excessive moisture and poor drainage.
How to fix it
Allow the soil to dry out completely before watering again and consider repotting into fresh, well-draining soil.
Fungal diseases
Why it happens
High humidity and poor air circulation.
How to fix it
Ensure proper spacing between plants and improve air circulation. If necessary, treat with a fungicide.
Care through the year
Spring
In spring, focus on watering regularly as the plant begins to grow. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives adequate water and consider providing afternoon shade in extremely hot weather.
Fall
In fall, reduce watering frequency as the plant enters dormancy. Continue to fertilize until late fall.
Winter
In winter, keep the plant in a cool location and water sparingly. Avoid fertilizing during this dormant period.
Toxicity & Safety
Maca is considered non-toxic to pets and children. It is safe for consumption and does not pose any significant health risks. However, excessive consumption may lead to gastrointestinal discomfort.
