Question
in my green house i have many fruit and vegitables that have encounted mould on the surfaces of the crops such as grapes,spinach and marrows. i have tried triming away the moulded grapes but they continue to come back making the bunches smaller and smaller can you tell me how to prevent this happerning? i have 2 other vines that have been growing  for a few years now and yet they still produce no fruit, could you tell the reason for this accurance? your sencirly nathanael longstaff.

Answer
Hi Nathanel, I hope you have adequate ventilation in your greenhouse, if that is OK then use a good all purpose fungicide as directed and let me know in a week to ten days how they look. your vines that produce no fruit might need pollination,get a soft bristle brush and brush the area where the grapes will form. you must do this every couple of days for a week.
