Expert tips
The key tip
Gynostemma loves a support (trellis, pergola) to flourish; what looks like initial weakness becomes a beautiful vine. Water regularly during growth (May-September), keeping the soil fresh without waterlogging.
The common mistake
Leaving the plant on the ground or thinking it thrives without water: it sprawls poorly, sparse foliage, few or no flowers, and dies at the first prolonged frost.
The pro's trick
In autumn, harvest the leaves before the first frost (0°C can weaken the plant); dry them to make healthy tea all winter long.
Care
Regular watering
Jiaogulan enjoys consistently moist soil but without waterlogging. Water regularly during the growth period, especially in hot or dry weather. Reduce watering in winter if the plant is grown in a pot and loses its leaves.
Ideal exposure
Place your jiaogulan in partial shade to dappled shade. It tolerates indirect light and prefers to be protected from the most intense rays. Too much direct sun can dry out the foliage.
Pruning and training
Prune regularly to encourage bushy growth and control its vigorous development. Pinch young stems to stimulate branching. Train on a support or structure to guide its natural climbing habit.
Balanced nutrition
Apply a balanced fertilizer every two to three weeks during the growth period (spring-summer). Choose a formula rich in nitrogen to promote foliage. Reduce fertilization in autumn and stop it in winter.
Appropriate substrate
Grow jiaogulan in rich, slightly acidic and well-structured potting mix. Mix leaf mold, specialized compost and perlite to ensure good drainage while maintaining slight moisture.
Problem prevention
Watch for mealybugs and spider mites, particularly indoors. Maintain good hygiene and adequate air circulation to prevent fungal diseases. If infestation occurs, isolate the plant and treat with natural methods.
Did you know?
Jiaogulan, called the "herb of immortality" in Southeast Asia, has been used for centuries in traditional Chinese and Vietnamese medicine. Its English name "five-leaf ginseng" reflects the similarity with ginseng, although these two plants belong to completely different families. Its leaves, slightly sweet with a subtle bitterness, can be enjoyed as an infusion.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
