About Japanese Arrowroot

Kudzu is a semi-woody, twining, aggressive vine that is native to Asia and Northern Australia. It was introduced in the United States in 1876 at the Philadelphia Centennial Exposition. In 1933 the U.S. Soil Conservation Service introduced a variety of Kudzu, Pueraria montana var. lobata, for erosion control and agricultural purposes. In the 1950s it was declared a common weed and in the 1970s it became a noxious weed.

🐶 🐈 👶 Toxicity

Greg does not have confirmed data on this plant’s toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, it’s always best to consult a medical professional.

If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA at US (888) 426-4435.


🪴 Soil

Japanese Arrowroot 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

Japanese Arrowroot 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

Japanese Arrowroot 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.


🌦️ Growing Outdoors

USDA Hardiness Zone
Japanese Arrowroot can be grown outdoors in USDA Hardiness Zones 5a-10b. Find your local hardiness zone here.


🌱 Propagation

Japanese Arrowroot can be propagated by division into new individual plants.

  • Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
  • If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
  • Pot up the new plant in well-draining soil
  • Repot the parent plant back into its original pot

🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
