Philodendron Selloum (Tree Philodendron) problems — and how to fix them
Philodendron Selloum (Tree Philodendron) (Philodendron bipinnatifidum (syn. Thaumatophyllum bipinnatifidum, P. selloum)) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Yellowing lower leaves
Usually a watering issue. Soft, drooping yellow leaves with damp, sour-smelling compost point to overwatering and incipient root rot; let the soil dry further and check drainage. Widespread yellowing can also signal a nitrogen, potassium or iron shortfall during the growing season.
Brown, crispy leaf edges
Typically caused by underwatering, low humidity or scorch from direct sun. Keep the compost lightly moist, raise humidity with a pebble tray or grouping, and move the plant out of harsh midday rays. Cold draughts can also brown the foliage.
Leggy, small or less-divided leaves
A sign of insufficient light. New leaves staying entire rather than deeply lobed, and long bare stalks reaching toward a window, mean it needs a brighter, filtered position. Rotate the pot regularly so growth stays even.
Sap-sucking pests
Spider mites, mealybugs, aphids and scale can colonise the large leaves, especially in dry indoor air. Inspect leaf undersides and stalk joints, wipe foliage regularly, and treat early with insecticidal soap or neem; raising humidity discourages spider mites.
