Dwarf Umbrella Tree (Schefflera arboricola) prefers medium to bright indirect light, moderate warmth, average humidity and moderately moist, rich, well-drained soil coupled with monthly feeding in the growing season.
Schefflera arboricola also called Hawaiian Schefflera or Dwarf Schefflera is among the popular fast-growing plants which will tolerate some level of neglect and easily adapt to a wide range of growing conditions.
Hawaiian Schefflera bears about ten leaflets radiating from each leaf-stalk. Under the right conditions, it will produce aerial roots which will convert to fully functional roots when they reach the ground.
Three conditions must be maintained for Dwarf Schefflera Tree to produce aerial roots. These conditions are a high growth rate, insufficient trunk roots (due to the plant being root bound or these roots are pruned) and a constantly high humidity.
Botanical name: Schefflera arboricola
Synonym: Heptapleurum arboricola
Family: Araliaceae
Common names: Dwarf Umbrella Tree, Hawaiian Schefflera, Dwarf Schefflera
Origin
Schefflera arboricola also called Heptapleurum arboricola is native to tropical regions of Taiwan as well as Hainan. It is one of the popular tropical foliage plants that will grow successfully in the home, office and other suitable spaces.
Dwarf Umbrella Tree gets its common name from its appearance as a smaller version of Schefflera actinophylla (Umbrella Tree). It is much easier to grow than Umbrella Tree and will happily grow as a bush if the growing tip is removed.
Size
Dwarf Umbrella Tree will grow to a height of 4-6 feet when grown indoors which places among the low-light trees for indoor growing.
Varieties
Many varieties of Schefflera arboricola can been selected for their variations in leaf color and pattern which are often variegated with creamy-white to yellow edges or centers.
Varieties of Dwarf Umbrella Tree include Hayata whose leaves are greyish, Geisha Girl with rounded leaf tips and Variegata with yellow-splashed leaves among many others.
Is Schefflera arboricola toxic to pets?
Yes. Schefflera arboricola is toxic to both humans and pets as listed by ASPCA. It contains "sharp" calcium oxalate crystals that are insoluble and damage cells and tissues of animals if ingested. The crystals cause swelling of the exposed tissue and the digestive tract which may be fatal to both animals and humans.

Light Requirements
Where do you put a Dwarf Umbrella Tree?
Dwarf Umbrella Tree grows best in medium to bright indirect light. Put it near a large, brightly-lit window but keep it away from direct sunshine to prevent scorching of the leaves.
The variegated types will require more light than the all-green type. They can be grown under a grow light where the natural light is inadequate.
Rotate the pot regulary to ensure that the plant receives light on all sides for uniform growth to prevent lop-sided growth.
Potting Soil
What is the best soil for Dwarf Umbrella Tree?
The best soil for Dwarf Umbrella Tree is a rich, well-draining soil to prevent it from getting soggy while providing the required nutrients. A blend of potting soil, perlite, and sand to enhance drainage is ideal for the plant.
Watering
How do you water Schefflera arboricola?
Water Schefflera arboricola liberally in spring and summer and allow the top 2-3 inches of soil to dry out between waterings. Maintain the soil moderately moist and avoid overwatering to prevent yellowing and leaf drop.
Decrease watering in fall and winter to keep the soil slightly moist as growth is minimal at this time. Do not allow the soil to dry out completely to avoid drooping and leaf drop.
Use a pot that has a drainage hole and well-draining soil to avoid getting soggy soil as it can result in root-rot and death of the plant.
Temperature and Humidity
Schefflera arboricola thrives in an average warmth of 16-280C. Keep it away from drafts to avoid flactuations in temperature as they can cause stunted growth and leaf drop.
Normal household humidity of 50-55% is perfect for Hawaiian Schefflera. However, too low humidity can result in brown leaf tips. Therefore, to increase humidity, set the pot on a wet pebble tray or use a cool mist humidifier. Do not mist and maintain good air circulation to prevent fungal diseases.
Fertilizer
What kind of fertilizer for Schefflera arboricola?
Feed Schefflera arboricola with a balanced, liquid fertilizer every 4 weeks in spring and summer for a lush growth.
Stop feeding in fall and winter as growth is minimal and feeding at this time may lead to fertilizer burn; brown leaf edges.
Regularly flush out accumulated salts from the soil by running a stream of water through the soil until the water comes out through the drainage hole. Allow it to run for a few minutes and repeat several times.
Repotting
Repot Schefflera arboricola every 2-3 years during the growing season when the plant becomes root-bound. Use a pot 1 size larger than the current one as it prefers to be pot-bound.
Ensure that the pot has a drainage hole as the plant does not like to be in soggy soil and it can lead to root-rot. Take a look at these ceramic pots with drainage holes on Amazon.
Pruning & Maintenance
Can you prune a Dwarf Umbrella Tree?
Yes. Pruning Dwarf Umbrella Tree involves:
- Removal of dead and yellow leaves to maintain the plant neat as well as reduce pests and diseases infestation.
- Regular pinching off the growing tips to encourage a bushy and compact growth, new growth will appear just below the cut.
- Cutting back leggy branches and stems a few inches above the soil level to encourage new growth. Use a sharp, clean pair of pruning scissors to minimize cross-contamination.
To prevent branching, do not pinch the growing tips and provide support for the plant to encourage upright growth.
The foliage emanating from the pruning can be used for taking cuttings to propagate new plants.
Regularly clean the leaves by damp-wiping with a soft cloth to get rid of dust and discourage pest infestation.
