Everything it needs
9 essentials at a glance
Watering
Gynostemma pentaphyllum prefers consistently moist soil but is sensitive to overwatering.
Water when the top inch of soil feels dry, typically every 5-7 days in warmer months and less frequently in cooler months. Signs of overwatering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in partial shade to full sun, ideally receiving 4-6 hours of direct sunlight daily.
It can tolerate some shade, especially in hotter climates, but too much shade may hinder growth. Ensure it is placed where it can receive morning sunlight and afternoon shade for optimal health.
Soil
Gynostemma prefers well-draining, loamy soil with a pH range of 6.0 to 7.0.
A potting mix that includes peat, perlite, and compost is recommended to ensure proper drainage and nutrient availability. Avoid heavy clay soils that retain water, as this can lead to root rot.
Humidity
This plant enjoys moderate to high humidity levels, ideally between 40-60%.
To increase humidity, consider misting the leaves or placing a humidity tray filled with water near the plant. Signs of low humidity include browning leaf tips and leaf drop.
Temperature
Gynostemma thrives in temperatures between 60-80°F (15-27°C) and is hardy in USDA zones 7-10.
It can tolerate brief periods of cold down to 20°F (-6°C) but should be protected from frost. During extreme heat, ensure adequate watering and shade to prevent stress.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or similar.
Fertilize every 4-6 weeks during the growing season (spring and summer) and reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves, poor growth, and leaf drop.
Pruning
Prune Gynostemma in late winter or early spring to encourage bushier growth and remove any dead or damaged stems.
Use sharp, clean pruning shears to make cuts just above a leaf node. Regularly deadhead spent flowers to promote new growth and prevent self-seeding.
Repotting
Repot every 1-2 years or when the plant becomes root-bound, typically in spring.
Choose a pot that is 1-2 inches larger in diameter than the current one. Signs that it needs repotting include roots growing out of the drainage holes and slowed growth. Carefully remove the plant from its pot, loosen the roots, and place it in fresh potting mix.
Propagation
Propagation can be done through stem cuttings or seeds.
For stem cuttings, take 4-6 inch cuttings from healthy stems in spring or early summer, remove lower leaves, and place them in a pot with moist potting mix. Keep the cuttings in a warm, humid environment until roots develop, which can take several weeks. Seeds can be sown in spring after the last frost.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by overwatering or nutrient deficiency.
How to fix it
Check the soil moisture and reduce watering if it feels soggy. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Wilting leaves
Why it happens
Wilting can occur due to underwatering or extreme heat.
How to fix it
Ensure the plant is watered adequately and consider providing shade during the hottest part of the day.
Leaf drop
Why it happens
Leaf drop may indicate stress from low humidity or sudden temperature changes.
How to fix it
Increase humidity around the plant and maintain consistent temperatures to prevent stress.
Root rot
Why it happens
Root rot is typically caused by overwatering and poor drainage.
How to fix it
Allow the soil to dry out before watering again and ensure the pot has adequate drainage holes.
Pest infestations (e.g., aphids, spider mites)
Why it happens
Pests can thrive in dry conditions or when the plant is stressed.
How to fix it
Regularly inspect the plant, and treat infestations with insecticidal soap or neem oil as needed.
Care through the year
Spring
In spring, focus on repotting if necessary and begin a regular fertilizing schedule. Ensure the plant receives adequate water as it starts to grow actively.
Summer
During summer, monitor for pests and ensure consistent moisture. Provide shade during the hottest parts of the day to prevent leaf scorch.
Fall
In fall, gradually reduce watering as the plant's growth slows. Prepare for winter by cutting back on fertilization and checking for any pests.
Winter
In winter, protect the plant from frost and cold drafts. Water sparingly, allowing the soil to dry out between waterings, and avoid fertilizing.
