So glad I found this page.. I have been trying to keep my AV alive for about a year. I was watering from the top. The room they are in is always about 70-72 .. and I found that I was having to water them almost every other day as the tops would be dried out. So - i switched to a water mat under the pot the other week and have having some difficulties as well. I will post pics and maybe someone can give me advice. I use AV soil from an AV store (online) and they are on a windowsill with east exposure -- indirect sunlight. One of my faves just died - with black roots and I cut them off.. and repotted the crown. Any suggestions as to what I am doing wrong is greatly appreciated.. I will post pics of the 2 that are doing the worst.
