I have had some crocuses in a pot for 2-3 years but last spring they didn't flower and it doesn't look as though they are going to this year either. Any answers to why or what I can do for next year will be gratefully received. Thanks
A lot of plants don't like living in pots as it isn't their normal habitat (too dry, too warm and too shallow). They were probably forced the first year too.
I would empty the pot into a hole in a shaded part of the garden over the summer, then re-pot into new compost in autumn and see what happens next spring. if they don't flower, throw them out!
