I live in Reading and have white seeded grape vines. When is the right time
to harvest please? Shall I leave them when the colour changes yellow?

Hello Rajinder,

Glad that the cuttings I gave you are now producing.

My grapes are not yet ripe apart from those I am growing against the
house. I shall probably need to pick them by the last week in September
to take them over to France to process into wine with my grapes over
there.

Were your vines affected by the late frosts? If so they will have been
knocked back a couple of weeks. Anyway, the best way is to taste one.
Every day that you can leave them on the vine will see an improvement.
