Belladonna's are tough critters and will they will grow in very dry conditions they also respond to an occasional drink.
Planting with the tops of the bulbs exposed is the correct way of planting them.
As to the non flowering, be patient, Bellas are one of a group of bulbs that do not appreciate being moved and usually sulk for several years before forgiving you and deciding to flower again
Brunsvigia is another one and has been known to either flower within 2 years or punish you for 10

Thanks Bob, for your response. My Belladonnas are still luxuriantly green but once they lose their leaves I will remember not to totally neglect them water-wise as I have done previously!
