Lifespan, Perennial or Annuals

How long is the lifespan? The reason behind its name is that it can live for several years, with some specimens even living for as long as 20 years. When mature, a Fatsia can reach a height of 20 feet. It is a fast-growing plant, and in just a few years, it can reach its full height.

Ideal Temperature

What is the ideal temperature? The Fatsia japonica is a tropical to subtropical plant that does best in climates where the temperature does not go below 50 degrees Fahrenheit. In the summer, the ideal temperature is 68 degrees Fahrenheit. During the winter, the plant needs a rest period at a temperature of 50-53.6 degrees Fahrenheit.


What about the humidity? The Fatsia plant does best in humid environments but can tolerate dry air for short periods of time. It is however good to spray the leaves with soft water daily or at least 2 times a week and then wipe them down with a soft cloth. This will help to keep the leaves healthy and free of dust.

Light Requirement

What amount of light this plant needed? Although Fatsia can adapt to lower light it does best with moderate indirect light. It also does well under artificial lighting. However, for the best, most powerful growth, sufficient lighting is necessary. If planting in an area that is bright, some shading may be required.

Soil Composition

What is good soil for Fatsia? If you want your Fatsia to thrive, the soil must be breathable. To improve drainage, sand or perlite should be added to the soil if it is too dense. For a mixture of your own preparation, you should take: 2 parts of leaf land, 1 part peat, sand, light turf and garden land. Always use a pot with a hole.

Watering Time

How much I must water Fatsia? While the fatsia is a drought-tolerant plant, it grows best if the soil is kept moist. Water at least twice a week, or every three days water the plant with at least three liters of water. In winter, limit watering to once a week.

Fertilizing and Nutritient

About fertilizer. Since Fatsia is a tropical plant, it will need consistent feeding during the growing season, which in most climates is spring through fall. Every 14-15 days, apply a liquid fertilizer, alternating between organic and mineral products. For organic options, consider using compost tea, fish emulsion, or kelp-based fertilizer. Mineral-based fertilizers are typically high in nitrogen, so choose one that is balanced or low in nitrogen. Always apply fertilizer to moist soil, and avoid getting any on the leaves to prevent leaf burn.


How to reproduce Fatsia? When trying to propagate a Fatsia plant, it is best to do so through apical cuttings that are 10-12 cm long and have several buds. The temperature during this process should be kept at 68-79 degrees Fahrenheit. Another method of Fatsia plant reproduction is through seeds. The temperature during seed reproduction should be 80.6 degrees Fahrenheit. The seeds should be planted in a mini-greenhouse and only slightly covered with soil. The container should then be placed in a dark location. When the seedlings have grown, the container should be placed in an area with scattered light but no direct sunlight. The glass should also be removed from the container at this time. As the seedlings continue to grow, they should be transplanted into individual pots.


Why Fatsia won't bloom? Sometimes, it blooms at the end of summer with plain white flowers, collected in panicles. Fatsia can also refer to the act of blooming or the state of bloom.

Transfer or Repotting

How much I must water Fatsia? The reason you would transfer your Fatsia is because the roots have come out of the drainage holes in the pot. This generally happens every spring. When this occurs, you'll need to replant your Fatsia in a pot that is not too big.

Caring The Fatsia

How to care the plant? So, in order to keep your Fatsia plant healthy, it's important to know a few things about its care. Fatsia is a moist-loving, shade-tolerant plant. In winter, it is desirable to provide a rest period in a cool place. Extruded plants need pruning.

The leaves of the plant fade and wilt at high temperature, long stems with large distances between the leaves are formed. The plant dries out in dry air. The leaves of the plant may turn light due to insufficient watering or sunburn. The plant grows slowly, the leaves turn pale green or brown due to the shortage of nitrogen in the soil. If the young leaves at the top turn black, the plant will most likely die from the cold. The plant is affected by spider mite, aphids, whitefly, mealybugs, thrips.
