T R O U B L E S H O O T I N G
Pale and “leggy” (reaching, leaves spaced far apart on stem): plant is not receiving enough sun.
Yellowing leaves, dropping: too much water.
Yellowing leaves, not dropping (not easy to pull off): too little water.
Browning leaves/tips: too little water or root rot, which is from a long period of over-watering. Rotted roots can no longer absorb water and actually cause the plant to die of thirst.
Mealy Bug Infestation: look for white, cottony-looking bugs and treat with rubbing alcohol on a Q-tip.
Aphid Infestation: black or yellow-orange bugs. Treat with a Q-tip soaked in dish soap diluted with water.
Scale Infestation: grey/brown dots that are actually hard shells with bugs underneath (eww). Scrape with rubbing alcohol on a Q-tip.
