just planted some corms bought from TV gdning channel. Followed instructions ie ensuring hollow side uppermost level with compost surface. Placed them on tray with water. hoping to soak the compost slightly. Should I have watered from the top or not at all? & if I need to water how often ? Have placed them on a window sill facing east with great hope. My second attempt. Last years was a failure.(Placed them in garage). Should I invest on a heated tray? My husband who was a keen gardener had a greenhouse & heated trays. The g/h I left behind when I moved & the heated trays just disappeared. Am really trying to make the best of my gden, which is too big anyway but that is another story. Thank you for your help.

I have just re read your post and it sounds as if your are being rather heavy with the water, they only need to be slightly moist until they get going or you can rot the new roots as they form. I will not be starting mine for 3 or 4 weeks yet.
