Currently there are three grapes Vitis vinifera growing in my garden. One of them is Pinot Noir and the other two are Cabernet Sauvignon. Although these varieties are commonly grown as wine grapes, my plants were originally intended to provide shade and these varieties were supposed to have beautiful colors in the fall. However, powdery mildew (Erysiphe necator) has always infected them late at the tail end of summer and therefore prevented them from showing off their autumn beauty. This pathological problem is worth noting nonetheless, they have always provided the shade which is very useful in this area and not only that they also produced enough grapes for making grape jelly that lasts us for more than a year.
