I've been struggling with this plant for over a year. First, new leaves quickly got brown tips and fell off, eventually leaving plant "naked". I was watering every two weeks according to instructions I got from some expert online. Then I read this plant requires more frequent watering and a certain type of soil. I removed it from the pot and examined the roots: no root rot. I replanted in easily drained soil with pebbles at the bottom (water moves out easily) and have recently been watering it every five days (or when the soil seems dry to the finger test). It now has leaves but one did turn brown at the tip. I read that the plant requires daily watering in summer (it's out on my terrace but not in full sun) but today the soil is still moist. I also read that in fall and winter it goes dormant and shouldn't be watered at ALL. I am without a clue here. What am I doing wrong?
