Fatsia japonica

Spring-Autumn · Indoors

Feed with houseplant food monthly

Using a balanced houseplant fertiliser, feed the plant monthly from March until September.

Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.

Spring-Winter · Indoors

Water to keep the soil moist

Water regularly when plant is in growth, and don't allow the compost to completely dry out as the plant suffers if its roots become dry. Do not stand the plant in water.

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water regularly during growth

Water regularly while in growth.

Adopt a regime that means the plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.

Spring - mid-late · Planting

Trim the plant

Trim the plant to give it a general tidy. This includes removing any lengthy or awkward shoots that make the plant look visually less attractive. Remove any spent flower heads at the same time.

Winter · Outdoors

Water sparingly during dormancy

In its dormant period give very little water, keeping the soil barely moist. Dormancy is likely to be during the winter and the plant recommences growth in early to mid spring.

When a plant enters dormancy the leaves fade, go yellow and then brown. Eventually the whole plant may 'disappear' or unadorned stems may remain.

Compost · Planting

Houseplant compost for repotting

Repot using any good quality house plant compost.

Indoor temperature · Planting

Average/cool room, cooler room (min 10C/50F) in winter

This plant thrives in average or cool rooms when grown as a houseplant (average room temperature is around 20C/68F). The minimum advisable temperatures at night and in the colder months are 10C/50F.

Indoor plant · Planting

Position in a bright spot, no direct sun

Give this a bright position away from the direct sun, especially direct sun at the height of the day. (Direct sunshine is too hot and can burn the leaves.) Move the plant to a brighter position in the room during winter and early spring.
