How Do You Take Care Of Dioscorea Japonica?
Dioscorea Japonica is easy to care for and requires little maintenance. Dioscorea Japonica prefers full sun to partial shade and well-drained garden soil. It grows well in a humid greenhouse and can be cultivated outside in warm garden settings in the temperate north.
To grow, the Japanese yam Dioscorea japonica requires continually wet soil. Water the plant in the morning every day, ensuring the top two inches are damp but not wet. It is recommended to get at least 1 inch of water every week.
Water a little extra in the summer to encourage optimal tuber growth. The following are the factors to consider when caring for Dioscorea Japonica:
Watering:
Dioscorea Japonica requires 1-2 inches of water every week. (Remember, the top two inches must remain damp.) The Japanese yam prefers moist soil, and it’s important to water it with water from a hose regularly.
It’s a good idea to put the Japanese yam in a tub or basin under the tap while filling it with water to keep the roots of your plant well-moistened at all times.

Dioscorea Japonica prefers well-drained soil. If using a pot, place the tuber in a large bowl. Fill the tub or basin with water to cover the tuber. Cover with a 2-3 inch layer of soil and allow to sit for several hours before submerging it in water.
Use a mixing potting soil and water your plant regularly. It is also a good idea to sprinkle a layer of well-rotted manure (and a little compost) on top of the soil every week.
Sunlight:
Dioscorea Japonica prefers full sunlight to partial shade. It can be grown in a greenhouse but prefers about 4 to 6 hours of direct sunlight per day. The sunlight will maintain a good temperature indoors, and the leaves will continue to photosynthesize. Indoor should be placed east or west window facing. Avoid direct sunlight before noon.
Temperature:
Dioscorea Japonica thrives in warmth between 65 and 86 degrees Fahrenheit. During the spring and summer, it can be brought indoors for indoor growth, but keep the temperature at a steady 70 degrees Fahrenheit.
Move your plant back outdoors in the fall when temperatures drop below 55 degrees Fahrenheit. This hardy Japanese yam can resist temperatures as low as -25°F and temperatures as high as 100°F.
Humidity:
Dioscorea Japonica prefers high humidity. During the spring and summer, it can be grown indoors, where humidity levels of 60-76% can be maintained. Humidity levels should be maintained at 70% during the winter months when temperatures are cooler.
Fertilizer:

Dioscorea Japonica is a heavy feeder. It needs lots of nitrogen and phosphorus. To fertilize, it’s recommended to use a complete fertilizer formulated specifically for jade plants with high amounts of phosphorus and plenty of nitrogen.
This will encourage fast growth in your plant and make it healthy. The fertilizer should be directed towards the top surface of your soil, where the leaves are growing.
Propagation:
The tuber division and seeds can propagate Dioscorea Japonica during the spring and summer. To propagate, use a sterile blade to slice the tuber into halves or quarters; each new tuber should have a bud at its center.
Let the cut section callus over for one day and plant it in the soil. It’s also a good idea to plant the cut sections in a bowl of water (covered by one inch of water) for several hours before planting in the soil.
Repotting:
Dioscorea Japonica can be repotted as needed. Repot in the spring every 1-2 years unless the soil becomes compacted. To repot, take apart the plant and use soil to break it up into pieces of about two inches.
Mix in some compost and manure, water well, and place into a new container with a layer of soil over the roots. Place the potted tuber in a sunny window until it is reestablished in its new container.
Pruning:

Dioscorea Japonica is a deciduous plant that does not require pruning. However, if you want to remove dead or dying leaves, simply pull off the old leaves. If the plant is getting too tall, cut the top of the plant back by 1/3 to 1/2 and water thoroughly.
The new growth will spring up again and look identical to the first growth. The best time to prune is in early spring, just as the plant is starting to grow.
Pests and Diseases:
Dioscorea Japonica is susceptible to attack by various pests and diseases, including two-spotted spider mites, mealybugs, root rot, and other fungal diseases. If your plant is suffering from any of these ailments, it’s important to treat it as soon as possible.
The most effective treatment for chrysanthemum mites or mealybugs is a preventative spray with a systemic insecticide. This should be done every week starting in March or April.
