the leaves on both my dendrobium and phalaenopsis are turning yellow and falling off i am noob and cant figure out what is the matter... also does anyone know of anywhere in toronto where i can buy orchid supplies
Not absolutely positive but both look like normal leaf death...as new growth adds to the top the older stuff goes. Doesn't mean you are doing anything wrong.
Welcome aboard ratz.Your dendro looks ok, but your phal looks like it's not getting enough water. The leaves look kind of wilted. Increase the humidity if you can, and don't let it dry out very much, they like it moist.
