Considering the Soil

About soil condition, Fatsia polycarpa grows best in moist but well-drained soil, in part shade. It's tolerant of a range of soil types including clay. If the soil is too dry, the leaves may turn brown and drop.

Light condition

So, like the other plants, Fatsia polycarpa requires a certain amount of sun to grow properly. However, this plant is much more tolerant to lower light conditions than most. In fact, it can even thrive in shaded areas where other plants would quickly die. This makes it a great choice for locations that receive less than ideal levels of sunlight.

Ideal Temperature

The temperature condition that is best for fatsia polycarpa is warm temperatures. This plant does not do well in cold temperatures and will die if it gets too cold. The ideal temperature range for this plant is from 68-75 degrees Fahrenheit.

Ideal Humidity

Ideal humidity condition for this plant is 50% and above. Fatsia polycarpa does not like to dry out, so make sure to keep the soil consistently moist but not soggy. If the air is too dry, the leaves will start to brown and drop off.


About fertilizer, this plant does best with organic compost or manure added to the soil around it in early spring. This extra food encourages growth and helps the plant to produce more leaves, which is its desired effect. In terms of its roots, the Fatsia polycarpa has a relatively shallow root system, so it is important to mulch around the base of the plant to help retain moisture and protect the roots from the hot sun.

About light

Pruning is an important part of taking care of your fatsia polycarpa plant. While it is possible to let the plant grow without pruning, it will become leggy and unruly over time. Pruning also encourages new growth, which is always a welcome sight in the garden. To prune your fatsia polycarpa, simply cut back the stems to the desired length. It is best to prune in the late winter or early spring, before new growth begins.

About Propagating

Propagation of this plant is typically done through stem cuttings. Cuttings should be taken from young, healthy plants that have not yet flowered. Cuttings should be about 6-8 inches in length and should be taken from the tips of the stems. The cuttings should be placed in a well-draining potting mix and kept moist until they have rooted. It is important to keep the cutting warm, preferably above 70 degrees Fahrenheit. Cuttings typically take 4-6 weeks to root. Once rooted, the plants can be transplanted into their permanent location.

Growth Rate

Usually, the plant growth rate information available is based on anecdotal evidence and observations. The plant typically grows quite quickly when conditions are favorable, but its growth rate can be highly variable depending on the environment. In general, fatsia polycarpa seems to be a relatively fast-growing plant, and it can quickly reach its full potential size under the right conditions.

Basic Problems

Common problems for this kind of plant are powdery mildew, leaf spot, and root rot. These problems are usually caused by too much moisture or poor drainage. To avoid these problems, make sure to plant fatsia polycarpa in well-drained soil and avoid overhead watering.
