Watering

Water Aralia balfouriana liberally during the growing season and allow the soil to dry out slightly between waterings to keep the soil moderately moist.

Regularly clean the leaves by damp wiping them with a soft cloth to get rid of dust and reduce pest infestation.

Feeding

Feed Aralia balfouriana monthly with a balanced, water-soluble fertilizer or a balanced water-soluble fertilizer during the growing season but do not feed during the cold season as growth is minimal at this time.

Flush out accumulated salts arising from fertilizers every 2-3 months by running a stream of water through the soil until the water comes out through the drainage holes. Let the stream of water run for a few minutes and repeat the process several times.

Potting Medium

The best potting mix for Aralia balfouriana should be rich in organic matter and free-draining to prevent it from getting soggy while providing the required nutrients.

Propagation

Polyscias balfouriana (Aralia balfouriana) propagation can be done at the beginning of the growing season from stem-tip cuttings or from hard-wood stem cuttings.

How to propagate Aralia balfouriana from stem cuttings

Take top 4-6 in. of the stem-tip cutting from a healthy Aralia balfouriana. You can also take about 6 in. hard-wood stem cutting.

Strip off most of the leaves from the bottom of the stem cutting. Retain at least 2-4 leaves on the cutting.

Dip the cut end in a rooting hormone to hasten rooting. Insert each cutting into a pot of moist sandy soil.

Cover the pots with clear plastic bag to create a humid atmosphere which enhances root development.

Place the set up in a warm, well-lit spot away from direct sunlight.

Note that the stem cuttings and newly propagated plants rot easily at the base and in the roots therefore do not mist the leaves and maintain the soil moist but not wet.

The cuttings will begin to root after a 4-6 weeks. You will know the cutting has rooted when you see new growth emerge.

Once rooting has taken place, gradually phase out the plastic bag covers.

Do not transplant the new plants as Polyscias balfouriana does not like to be disturbed. It is advisable to start the cuttings in pots with adequate room for the young plants.
