How to fertilize Chinese Yam

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Chinese Yam after it doubles in size or once a year—whichever comes first.

Chinese Yam prefers for the soil to dry out between waterings and should be watered regularly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.

Soil
Chinese Yam does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
Fertilizer
Chinese Yam is a fast growing plant and may deplete the nutrients in its soil over time. Replenish them with a gentle organic fertilizer or compost every 1-2 months depending on your location and season. Fertilize more often during the growing season and in warmer and brighter climates.
Growth Pattern
Chinese Yam is a naturally climbing plant and can be trained to climb indoors if you provide a moss pole or trellis. The newest growth will emerge from the end of the stems.
