I've been a small time gardener & veg grower for a number of years but had never suffered the dreaded blight! It got my potatoes & tomatoes last years. For once I grew the greenhouse tomatoes in grow bags and due to new veg plot being put together my spuds were also in bags. Outdoor tomatoes straight into soil. However, NOTHING WAS SPARED!! Normally I’d tip the compost from bags back into garden & dig in, but I couldn’t make up my mind up whether this was a good idea or not & so the bags still sit there..... Is it safe & if not what to do with it??? Can somebody help me with this blight plight??
