Arum Lily Problems
I am a keen but new owner of a big garden. One area is very shaded by 7 medium sized trees and bushes and a big monkey puzzle. About six weeks ago, in among lily of the valley shoots and bluebells most of the area seemed to be shooting arum lillies as well. The previous owner said that they had never been there before. They grew to about 1' and flower buds formed. However as they were monopolising the whole area and other flowers could not be seen I pulled about 2/3 of them up. Now the flower buds on all the ones left appeared to have rotted. Any suggestions gratefully received.
