Chewbacca you have to be patient with them. When you buy them in flower, they’ve been forced & won’t flower again probably for another year, at least. But they will, eventually.
I have an orchid intensive care windowsill in my utility room. It faces west. When the flowers have all fallen off the spike they go there until they’ve gathered their strength sufficiently to produce another flower spike, when they get moved somewhere where I can see them.
They only need a little water & occasionally a small feed with miracle-gro.
Eventually they get too many air roots & look straggly & unattractive & they get consigned to the compost heap.
But most of them flower for years & are much better value than cut flowers.
