I have a front garden border with tulips which were planted in the winter. They came up a few weeks ago and were a loverly display. Earlier this week two of them had there flowers 'snipped' off about 2 inches below the petals. Now there are 4 that have suffered the same fate. I dont know that if the fact that the one affected are all yellow in colour has any baring on it but none of the other coloured tulips have been touched. Also the heads are just lying by the plant and haven't been eaten or collected.
Does anyone know what could be the reason for this? I live in a Glagow city suburbs with very few wildlife issues to worry about.
