Hi all, I recently moved into a new house where I'm lucky enough to have many established fruit and vegetables. Problem is, Ive never grown grapes before and clearly one of my vines having issues. The trunk is quite thick so it is an older plant, it is a red grape of some sort but unsure of exact variety. Fruit growth is stunted - only one bunch of grapes which are all very small. Leaves are very discoloured and have been for much of the growing season - red blotches, some leaves are yellow, some also have brown spots. Lots have died and dropped off the vine. PH at about 250mm deep is about 6.5. Anyone know what's going on?
