Hi Sanjo, where in Essex are you?

I have tomatoes in sacks and yes I got blight! friend had potatoes in sacks in garden- no blight!

I have used the same sack outers this year, but changed the compost as chance I have to take!

Blight seems to be air borne, not sure if it stays in the soil/sacks, this is why I am testing it out this year with re-using the same sacks, just to see what happens.
