From experience, one thing I have learned about houseplants is to keep them pot-bound. They seem to put out more flowers that way. If I give them a bigger container, they seem to spend all their time growing roots. My plants dry out between watering and I fertilize only once a month.
Thanks chelsea That works for the nite blooming cereus, af violets, and snake plant , silver quill. All the above worked for me. Also amaryliss
