Hey Tom, many thanks for you quick reply! I'm heading to the store to buy one of the fungicides you suggested. My plant bloomed this week, so that ought to be just in time for the fungicides... Thanks again!
Hey there, my grapevine is suffering from a disease which i find hard to identify. The leaves get brown spots all over them, but there is no white residue eiher on top or underneath the leaves. Can anyone help me identify and possibly cure this?
