Is it Normal for Schefflera Leaves Turning Yellow?
Nope, it is not normal for an evergreen houseplant like Schefflera to experience yellowing leaves.
Natural yellowing should not worry you until there are only 2-3 yellowing leaves every month.
However, anything exceeding a few leaves may suggest other grave problems with your plant.
Yellowing leaves are the signs of a stressed plant, and it is frustrating to see your beloved plant under stress despite providing enough maintenance.
What Causes Schefflera Leaves Turning Yellow?
Schefflera leaves turn yellow for many different reasons. The causes of yellowing leaves and their appropriate solutions and preventions are mentioned below.
1. Overwatering Issues
Overwatering is a significant concern for houseplants like Schefflera, which react to waterlogging quickly with yellowing or spotted leaves.
Normally, Schefflera needs water every 5-10 days in spring and summer.
Too much water in the soil causes the roots to get less oxygen and causes root rots.
On the other hand, underwatering will dry the soil and wither the roots.
In any case, yellowing leaves are the first sign of uneven watering.
- Cut back on watering and misting the plant immediately and wait until the problem subsides.
- Throw away any drained water collected on the saucer.
- Check the top half inch of soil for dryness before watering again.
- Inspect the surface for dark brown soil as opposed to light-grey color.
- Gradually increase water intake to 1.5 liters without overwatering the plant.
- Cut back on watering to once every fortnight in fall and winter and limit the water to 1 liter.
- Avoid using too hold or cold water when watering. Schefflera plant prefers room temperature water (68°F).
2. Low Humidity
Schefflera is a humidity-loving houseplant.
High indoor humidity keeps the plant parts and soil moist. Thus, a lack of moisture in the air may cause yellowing leaves.
Schefflera plants demand 60-80% ambient humidity.
The plant can withstand slightly high humidity, but the leaves become yellow in low humidity.
It is more common during winter when a heating unit is on, and ventilations are shut down.
- Install a humidifier or group your moisture-deprived plant with other houseplants in the room to spike up the humidity.
- Mist the plant a few times a week until the yellowing subsides.
- Keep the plant away from air conditioning or heating vents.
- Place the potted plant on a pebble tray with water to raise humidity levels.
3. Direct Sunlight
Sunburn is the primary concern for sensitive houseplants like Schefflera, where the direct sunlight on the leaves can scorch them.
Provide your Schefflera plant with 3-4 hours of indirect sunlight daily.
Although the plant enjoys filtered sunlight, placing it close to the light source can cause sunburn too.
- Place the plant near an east-facing window or keep them 3-5 feet away from a south-facing window.
- Do not place the plant under the sun to compensate for low lighting.
- Trim away the affected leaves with disinfected pruning shears to clear the sunlight for the inner leaves.
- Rotate the plant once a month for even light distribution throughout the foliage.
4. Pest Problem
Although pest infestation is uncommon with the in-house Schefflera plant, you should know about pests that can cause yellow leaves.
Additionally, pest infestation may cause wilted or springy leaves, black spots, and tiny holes.
- Isolated the infected plant from the other healthy houseplants to prevent the spread of infection.
- Use warm soapy water to wipe pests from the plant parts.
- Snip off all the infected leaves from the plant and burn the plants down.
- Never keep leaves, fresh cuts, and garden plants close to the Schefflera plant.
- Keep the room clean and well-ventilated, allowing air to pass through the plant leaves.
5. Low Temperature
Leaving Schefflera plants outside in winter can invite cold drafts that will contribute to the yellowing of the leaves.
Schefflera plant ideally enjoys a warm temperature ranging between 65°F and 90°F.
Although Schefflera survives below 65°F, anything below 60°F will stall the plant’s growth.
- Remove them from the room that has an air conditioner installed.
- Keep the plant in direct sunlight for a few hours during winter mornings.
- Place the repotted plant in the exact location to maintain the optimal temperature.
- Cover the plants with frost blankets during winter nights.
- Situate small potted Schefflera plants inside greenhouses or indoor terrariums to offer them a steady ambient temperature.
6. High Fertilizer
Overfertilization proves to be a curse to Scheffleras, that may only enjoy occasional feeding.
Generally, Schefflera needs a well-balanced liquid fertilizer every 1-2 months in spring and summer. Cut back fertilizer application in fall and winter when the plant is dormant.
Too much plant feed or a higher ratio of NPK in the fertilizer (during dormant times) will burn the roots and affect water and nutrient uptake.
- Flush out fertilizer salts by running the potted plant under distilled water 4-5 times.
- Remove the yellow leaves to cope with the nutrient uptake from the soil.
- Resume fertilizing only after the problem subsides and feed the plant once every month during the growing season.
- Dilute the fertilizer to 1/2 or 1/4th strength and apply after watering the plant.
- Do not fertilize until 6-8 weeks after repotting Schefflera.
Should I Remove the Yellow leaves?
Once the Schefflera plant leaves turn wholly or partially yellow, you are less likely to overturn them.
Thus, pulling away yellowing or dead leaves will ensure your plant keeps looking its best and make way for new growth.
- Pull away the old leaves using your fingers.
- Pluck as close to the stem as possible and dispose of them immediately.
- Alternatively, use disinfected shears to cut the leaves with the least hassle.
FAQs About Schefflera Leaves Turning Yellow
What kind of soil can prevent Schefflera leaves from turning yellow?
Schefflera plants need porous, rich, and loamy soil with a pH adjusted between 5.5 and 6.5.
This kind of soil can drain the soil water well and prevent soggy soil conditions.
How to water Schefflera plants to prevent yellow leaves?
Water the plant thoroughly on the topsoil until it drains from the bottom drain holes, and wipe water drops festering on the bottom leaves.
You can also try the approach of bottom watering by placing the plant on a watering tray for 15-20 minutes to saturate the soil.

Keep the Gardening Tools Clean!
Dirty gardening tools can carry pathogenic spores, making their way to the leaves, stems, and soil during repotting, propagating, and pruning. Always remember to disinfect them before and after the job is done!
