Schefflera Dropping Leaves: Cold, Water, Light or a Move?

Updated

Why is my Schefflera dropping leaves?

An umbrella plant drops leaves when it is chilled, kept too wet, short of light or humidity, or moved to a new spot. Clemson Extension names excessive watering, low humidity and chilling as the usual causes, and a recent move can add a few weeks of shedding.

What to do first

Check the mix and the saucer first, then the temperature at the plant (keep it above 16 °C / 60 °F at night and away from vents and doors). Give it bright, filtered light, water only when the top of the mix has dried, and leave a newly moved plant in place for a few weeks.

A schefflera dropping leaves is a stress response, and the cause is usually in its surroundings rather than a disease. Clemson Extension’s schefflera factsheet says leaf drop can be caused by excessive watering, low humidity or chilling. Plant diseases, it notes, are very rarely a problem indoors.

This applies to both plants sold as schefflera: the dwarf umbrella tree (Schefflera arboricola) and the larger umbrella tree (S. actinophylla). NC State Extension now files both under Heptapleurum. If you are not sure which you have, see how to identify a schefflera.

Start with what changed

Leaf drop usually follows a change. Think back over the last two or three weeks:

A recent move

Clemson’s houseplant disorders factsheet says some leaf drop occurs when plants face a significant change in environment. It says this drop should last only about three weeks. A schefflera fresh from a bright nursery often sheds some leaves in a dimmer home.

If the mix and temperature are right, leave the plant where it is. Moving it again restarts the adjustment.

Cold and drafts

Scheffleras are tropical. Clemson recommends day temperatures of 18–24 °C (65–75 °F) and nights above 16 °C (60 °F). It says to keep them above 10 °C (50 °F), and that dead areas form on leaves several days after exposure to excessive cold. NC State gives a preferred range of 18–32 °C (65–90 °F) for the umbrella tree, with temperatures above 16 °C (60 °F).

Clemson warns to keep scheffleras away from heat vents, radiators, open windows and air conditioners, because hot or cold drafts damage them. University of Maryland Extension says indoor plants are sensitive to drafts or heat from registers, and that temperature extremes can cause leaf drop. In winter, check the spot by a cold window at night.

Too wet, or too dry

Clemson names excessive watering first. Its advice: water thoroughly, then let the mix dry to about 1.3 cm (½ in) deep before watering again, and never let the plant sit in water in its saucer. For the dwarf umbrella tree, NC State says to let the soil dry out and then soak it thoroughly, in a well-drained mix.

Clemson’s disorders factsheet adds that both over- and under-watering cause leaf drop, and that plants in pots that are too small drop leaves. If the mix is wet, the pot is heavy and leaves are yellowing before they fall, check the roots. Our root rot guide covers what healthy and rotten roots look like.

Light and humidity

Clemson says scheffleras prefer medium to bright light, and that low light causes yellowing leaves with spindly, weak stems. NC State suggests a south, west or east window with filtered light, such as through a sheer curtain, for 3 to 4 hours a day for the dwarf umbrella tree. It warns that bright direct light indoors burns the leaves.

Low humidity is Clemson’s third cause of leaf drop. NC State says the dwarf umbrella tree likes high humidity and suggests a tray of wet pebbles, with the water line below the base of the pot.

Bare lower stems are partly normal

Losing the lowest leaves over time is how the umbrella tree grows. UF/IFAS notes that on outdoor trees the lower portions of the trunks lose all their foliage over time, and that the trees can be topped to create layers of foliage. Clemson says scheffleras can be pruned to keep them lower; prune just above a leaf.

What to do now

  1. Check the mix and saucer. Let wet mix dry to about 1.3 cm (½ in) before watering again. Empty the saucer.
  2. Move it out of drafts. Away from vents, radiators, doors and cold glass.
  3. Give it bright, filtered light. No hot direct sun through glass.
  4. Add humidity in heated rooms. A pebble tray, as NC State suggests.
  5. Hold off on feeding. Clemson says plants in lower light need less frequent feeding.
  6. Wait for new growth. Fallen leaves do not regrow from the same spot. Judge recovery by new leaves at the tips.

If you see sticky leaves, fine webbing or cottony tufts, pests may be adding to the stress; see the spider mite guide. Keep fallen leaves away from pets: the ASPCA lists schefflera as toxic to dogs and cats.
