During the past few days some bedding plants, which were still in
shallow seed trays in the greenhouse, suddenly withered and died. On
inspection of their roots I found a white maggot type creature in the
compost. In another tray I found many chestnut brown cocoons/pupa
amongst the compost. This was compost I purchased from a garden centre
(Arthur Bowers) Does anyone know what these pests are and where they
probably came from?
Thanks
