David, no disrespect to you but that looks like a pretty poor potfull of bulbs. As an experienced gardener but a novice at Crocus I would guess that you went to the local garden centre and bought a bag of their stock. I have never known such a bag only contain five corms and looking at the gaps in the pot I suspect that some have not come up. Also, with first year growth of newly purchased corm I would expect them to flower pretty evenly. Given good stock to start with it is difficult not to get a display in the first year so I doubt that the problem is with you. It looks to me as if you have been sold a bag of crocus that have not been properly looked after.
David, your conditions are 'harder' than mine! I would put the crocuses on top though.
