Use these instructions to care for a Threadleaf Aralia plant. This guide will tell you how to water your Threadleaf Aralia; its light, temperature, and humidity preferences; and any additional care your plant might need to help it grow.
Your Threadleaf Aralia will do best in medium to bright indirect light. They tolerate medium light, but will grow faster and fuller in a bright spot.
Water your Threadleaf Aralia just enough to keep it from wilting. It’s best to let the top inch or so of the soil to dry before watering again. It may be a couple times a week to once every two weeks, depending on the size of your plant and how much light it gets. If in doubt, it is best to keep it on the drier side rather than too wet—always make sure your pot has good drainage.
Like other popular indoor plants, your Threadleaf Aralia appreciates humidity. Feel free to mist your plant occasionally to keep it happy.
The Threadleaf Aralia is comfortable at ordinary room temperatures between 65 and 85 degrees. Do not expose it to temperatures below 60 degrees because cold air will damage the foliage.
Fertilize your plant every 4-6 weeks during the spring and summer, and once every eight weeks in the fall and winter.
The Threadleaf Aralia does not like to be moved. A sudden change in location will cause leaves to drop off. Make environmental changes gradually, and try not to move the plant in the winter. It also benefits from being repotted every couple of years; spring and summer are best, but you can re-pot an Aralia any time of the year without harming it. When repotting, look for a container that is only a couple of inches wider than the previous pot, Threadleaf Aralias prefer a tight-fitting pot.
Relatively low toxicity to pets and humans. Typically, ingestion will cause mild mouth and low stomach irritation.
