Coffee Houseplant Trouble
I have a coffee tree that I am growing as a houseplant. During the summer months, it it's leaves started turning brown and falling off. Also, there are white puffs on the nodules of the branches. It is in a room with bright light and average humidity. I was watering it once a week in the summer (drenched it). I tried a 50/50 mixture of rubbing alcohol and water and hasn't helped at all. I have also increased watering to everyday and that doesn't seem to affect it. I may have tried a 50/50 mixture with some ivory soap when I first had the problem. However, it came back. Maybe I should try the soap again? What do you think is going on. Thanks in advance.
