This is my second season with this concord grape vine. Last year the vine was healthy and developed lots of grape bunches but the birds got them before i did! This year it has tonnes of bunches but I noticed over the last week or so many of the grapes are starting to turn a purple then brown and then they shrivel up! Can I help them..have I done something wrong? Thanks
Has anyone seen this before? With all the reading I've been doing it appears to match the description of Botrytis Bunch Rot of Grape (Botrytis cinerea) the closest..except they don't appear to be moldy in anyway...they have just shrivelled. Thanks, E.
i might think it is rotting...have you ever opened a bage of grapes from the store and noticed that there are brown mushy grapes? that means it it rotting and i has not been picked on time......
