Schefflera Leaf Drop: Systematic Diagnosis and Watering Correction

Schefflera drops leaves daily; tips black, leaves black/brown spots, tiny black spots on undersides. Tried alcohol/baking soda, dish soap—nothing works. Worried about spread. Expert Rick:

1. Check undersides for bugs: fine webbing = spider mites (mottled leaves); brown spots = scale.
2. Bag affected leaf, take to local garden center (not chain) for ID and product advice.
3. If bugs: hose off, spray safer soap insecticide.
4. Leaf drop often = moved to lower light. Fertilize weekly–monthly in growing season.
5. Main issue likely improper watering: water by weight. Saucer under pot, water, sit 5–10 min, drain excess, pot should feel heavy. Rewater when considerably lighter. Indoors check every 5–10 days.

Home remedies often do more harm than good.
