why did the snowdrops that i planted last year in the green not come up in my garden this year

is it possible the squirrels or mice ate the bulbs?

It is possible but my neighbour has a wonderful display, over the years I must have planted 5,000 snowdrops in the green in both my front and back garden.

Perhaps they will flower next year,as you planted them in the green they should be O.K.

oh, I didn't realise you still had the greenery - so yes, maybe they'll come into flower next year
