Couple of culture questions (D. lindleyi, Galeandra magnicoluman)

[jpenguin]

Hi Everyone,

I just have a couple of quick culture questions!

1. My Dendrobium lindleyi bloomed profusely this spring. The flowers have since wilted, so I cut the spikes off after they dried out. I noticed it wasn't putting out new bulbs or leaves. This week, I saw it was growing another spike-should I cut the new spike off to encourage vegetative growth or let it bloom again?

2. I've recently acquired a Galeandra magnicolumna but was struggling to find culture info on it. Should I grow it like a catasetum?

Thank you all!
