Re: Help diagnose this banana
-I water it about 2 or 3 times a week in the winter - Stop watering so much, let it dry a bit between watering every other week or so.
-I recently fed it for the first time in 3 months - Don't feed during dormant winter months.
-The air humidity is really low so I spray the leaves about once or twice a day. - Get a Humidifier, preferably a warm water steam one. will help to keep it warm too.
-It gets pretty cold at night where I live - BUT how cold in the are where the plant is? Document that with a thermometer, and then keep the area warm at least 60°
This is what I do in the winter in my greenhouses in San Diego.
