Hello,

About 2 1/2 weeks ago I bought two on the sale rack at lowes.

One was 5$ and it has A big cane and 3 smaller ones. The big one had a spike but browned and i cut it down.
I first had them planted it sprgm moss but this week felt it was too wet so I put them in mix of fir bark, hardwood charcoal, and coarse perlite. (also had a tag that said dendrobium 44-08/#67 world cup no2)

The other was 3.50$ and has one big spike and one smaller one. The big one had a spike but also browned and I cut it off.

So could someone help me with them thank you very much
