Ayrshire, United Kingdom
3 years ago I planted a green gooseberry bush which has done really nicely, 2 years ago a red gooseberry was sited next to it, did fine too. What happened this year was that someone gave me a blackcurrant (which I do not even like, but thought I might just as well try) and I planted it next to the gooseberries (due to lack of space somewhere else. Now the green gooseberry is covered in American Mildew. (The red one is absolutely fine, it's a resistant variety anyway.) I suspect as blackcurrrant is a carrier of this mildew (googling told me) that that's the reason the gooseberry looks so dreadful. I do organic gardening and do not want to use chemical fungizides, any suggestions what to do? Thanks.
