I have some of that rough stuff in their pots for them to grow on.
Probably what I have...sorta looks like bark chips.
I got my skewers at Wal-Mart...100 in a pack for less than 2 bucks. They also have them at most of the "Everything Costs A Dollar" stores, and even the grocery store.
The one that is growing
best has two little nodes growing
right above where it comes out of the bark. is that some more of it's roots? Or is it trying to create more stems?
Hmmm...hard to say without seeing it, but you will be able to tell pretty soon. When a new stem pops out it doesn't take long to shoot right up there!
