New to orcids need basic advice

[cabnc]

Assume your two new plants have no tags. Since you have a Phal Sogo, assume your new plants are not phals. The one with 'leaves', do the leaves sprout from 'pseudobulbs' ? Reed like stems, ie canes, sounds like it may be a dendrobium, do not remove the canes. A picture would be really helpful.
Most orchids like pinched feet. But after a few years the potting mix breaks down and holds too much moisture for too long leading to root rot. And they need to be repotted more to replace the mix than to increase the pot size.
Potting mix - everyone has their favorite based on type of orchid, growing conditions, etc. As a novice I use clear plastic pots (to see inside to know when to water); packing peanuts in bottom third for air flow; and store bought bagged mix of fir bark, charcoal & pearlite. This allows me to water (perhaps too often as now, plants are outside with days of rain) but the roots are damp but not sitting in water.

As you said, enough for one post :0
