Common problems
Yellow leaves
Reason: Overwatering, low light, or older lower leaves aging naturally.
Solution: Let the potting mix dry appropriately, improve light gradually, and remove only fully spent leaves.
Leaf drop
Reason: Sudden stress from drought, overwatering, relocation, or strong afternoon sun.
Solution: Stabilize care, avoid frequent shifts, and return to a steady watering and light routine.
Soft stem
Reason: Stem or crown rot caused by excess moisture and poor drainage.
Solution: Remove damaged sections, repot into a fast-draining mix, and water less often.
Wrinkled leaves
Reason: The plant is drawing on stored moisture after staying dry too long.
Solution: Water deeply, then allow the mix to dry to the right level before watering again.
Leggy growth
Reason: Insufficient light causes stretched stems and wider gaps between leaves.
Solution: Move the plant to brighter light slowly and trim or propagate stretched parts if needed.
Sunburn
Reason: Harsh direct sun after shade-grown conditions or strong summer afternoon exposure.
Solution: Shift to bright filtered light or gentler morning sun and acclimate the plant gradually.
Pests
Reason: Mealybugs, aphids, spider mites, or scale may appear when airflow and plant vigor are poor.
Solution: Isolate the plant, wipe pests away, and repeat neem oil or insecticidal soap treatments as needed.
Root rot
Reason: Roots stay wet too long in compact soil or a pot without drainage.
Solution: Trim damaged roots, repot into airy mix, and never let water stand around the root zone.
Recovery tips
- Recovery tips
- Trim dead growth, improve drainage and light, and resume care slowly rather than overcorrecting all at once.
