Bad Grapes Gone Wild

Last night Stefania and I were back in Morgan Hill for a dinner meeting at a local pub down there. As we parked Stefania spotted these growing on the fence that divides the property lines. Unlike the bright healthy plants from our bike ride, these were withered and browning from powdery mildew.

This is an advanced stage of the disease. The white powder of the early stages has turned brown and dirty. The leafs have started to curl and die. Growth is stunting the plant and the mildew has spread to the grapes.

The berries are underdeveloped and will not get ripe. You can see the leafs starting to curl here, the first step in their death. The plant will survive through next year and onwards after that, but it will not produce any ripe fruit. The berries you see here will turn brown in a few months and fall off.

We had started the evening though with a more hopeful sight. We visited the Sesson vineyard in Coyote Valley. Jerry had spent the day tieing down new cordons and we were checking on his progress. The vineyard needs another mowing, but it seems to be fully recovered from the training mishap of last year and should produce some fruit next year.
