How to fertilise Schefflera (Schefflera arboricola)— schedule & NPK
Also called umbrella tree, dwarf umbrella plant, parasol plant.
About Schefflera
Schefflera arboricola · also called umbrella tree, dwarf umbrella plant · tropical
Schefflera is an umbrella-leaved tropical tree from Taiwan, fast-growing and light-hungry. The dwarf species (S. arboricola) is the common houseplant form; the giant S. actinophylla is rarely grown indoors. Toxic to pets.
Schefflera arboricola (Heptapleurum arboricola), the dwarf umbrella tree, is an evergreen shrub native to Taiwan and Hainan Province, China, where it grows free-standing or clings to other tree trunks as an epiphyte.
A moderately vigorous grower that responds to regular balanced feeding through the growing season, tapering off in winter.
Growth habit: Branched evergreen tree or shrub
Watch for — Brown patches: Sunburn or pest damage.

What fertiliser schefflera actually wants — and why
Schefflera is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for schefflera: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed schefflera, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For schefflera:
Balanced liquid feed at half strength every 4 weeks during the growing season. Treat that as every 4 weeks between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when schefflera is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for schefflera
Half strength is the safe default for schefflera — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water schefflera first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the schefflera watering schedule.
Signs you are over-feeding schefflera
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for schefflera:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding schefflera
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full schefflera care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of schefflera with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for schefflera
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
Fertilising schefflera — frequently asked questions
What fertiliser does schefflera need?
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula. Schefflera is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
How often should I feed schefflera?
Balanced liquid feed at half strength every 4 weeks during the growing season. Balanced liquid feed at half strength every 4 weeks during the growing season. Treat that as every 4 weeks between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
What strength of feed for schefflera?
Half strength is the safe default for schefflera — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
What does over-feeding schefflera look like?
Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding schefflera year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of schefflera?
Flush the pot of schefflera with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
