I have a small woodland area with lots of clumps of snowdrops. Last year many rotted off. Thinking that is was due to wet leaves I raked them all off this year, but still many are rotting off (but less than last year). The top and the bulbs look fine, but the stem underground 40/50mm has rotted to almost nothing. Some clumps are more affected than others. Any ideas?
