I never knew that dendrobiums needed a resting spell. I've always watered mine and it blooms every year. It looks kinda stressed now. I fertilized it about a month ago with Osmocote. It's a purple one. How can I find out what kind it is?
Look at where the flowers come from, if they appear at the sides of the pseudobulb (cane) in groups of two or three it is a soft-cane or nobile type.
If the flowers grow on a long stem coming near the top of the pseudobulb it is probably a warm growing type that doesn't need a rest.
Does the plant have a name tag?
It didn't have a tag when I got it. It has the long stem at the top of the plant. Thanks. I'll have to look and see if I can find the other kind. Do you think most stores carry what I have instead of the other one?
The type you have is more common in the south. The nobile types prefer a cool climate and need a rest. I hardly ever see them for sale where I am.
Yours may be a phalenopsis type. look it up and see if the blooms look similar. If so, it can get pretty large, unless it's a miniature one.
