Hi
They will strugle if in doubt place/sit the corms on damp compost and put in the warm airing cupboard in about a week you will see tiny shoots and roots so you will know which way up , normaly the bottom is round and the top has a little dip in the middle
We all had to learn you will soon know which way is which
Hope this helps let us know how you get on
