Ming aralia (Polyscias fruticosa) care

Trees · fussy to keep

Ming aralia (Polyscias fruticosa) wants bright indirect light. Water it weekly. Keep evenly damp, never soggy, and never let it dry out completely — an aralia that dries hard defoliates. Pot it in free-draining compost with perlite. Balanced feed at half strength monthly in spring and summer, and repot every 1.5 years. Humidity: above 60%. This is a genuinely humidity-hungry plant. Toxic to cats and dogs — the saponins cause vomiting and mouth irritation.

Ming aralia: finely divided lacy foliage on twisting woody stems, slow-growing and sculptural, and a traditional bonsai subject. It is the fussiest plant in this section — it drops its leaves at any change and wants humidity above 60% — but a settled one is beautiful and very long-lived.

Watering a Ming aralia

Water weekly. Keep evenly damp, never soggy, and never let it dry out completely — an aralia that dries hard defoliates.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright indirect light. Aralias drop leaves when they are moved, when it gets cold, and when the light changes — a stable bright position matters more than an ideal one.

Humidity and temperature

Above 60%. This is a genuinely humidity-hungry plant. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

Ordinary compost with a third perlite. They want steady moisture without sitting wet.

Feeding

Balanced feed at half strength monthly in spring and summer. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot every 1.5 years. Every second or third spring; they are slow and dislike disturbance. Expect leaf drop afterwards.

Common problems

Sudden leaf drop
A change: a move, a draught, a cold night, or the compost drying out.

Fix: Put it somewhere stable and bright, keep it evenly damp, and be patient.
Spider mites
Dry air. Aralias attract them reliably.

Fix: Raise humidity and treat weekly for a month.

Propagation

Stem cuttings in spring under a propagator lid, with bottom heat if you have it.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Toxic to cats and dogs — the saponins cause vomiting and mouth irritation.

Questions people ask

How often should you water a Ming aralia?

Water weekly as a starting point — that is the cadence PlantParlour sets for Polyscias fruticosa. Keep evenly damp, never soggy, and never let it dry out completely — an aralia that dries hard defoliates. Light, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.
