    Ficus Microcarpa help

    I currently have two ficus microcarpa. The first is tiny and I've had it since the fall. It seems to love my apartment conditions so I made a much larger investment on a second one. The new one is about 25" tall out of the pot, so something fairly large that I desperately want to keep alive...

    Fretting about overwatering - a myth nowadays

    If one doesn't use those "humidity trays" to keep the bottom of the pot underwater full time, if one has the drainage holes unclogged, if one uses a good modern fast draining mix as a substrate... Then there are no such things as overwatering and root rot. In my modest experience, even using...

    Roots Through Drainage Holes

    Hey everybody, I've had my bonsais a bit under a year (started from seeds) and am seeing my Ficus and Jacaranda growing roots through their drainage holes. Originally, I was under the impression that water that drains should be left in these trays to help with humidity, especially since they...
