For many years my crop of concord grapes did well and where ready for home made consumption at this time last year.
This year 2022, we have another good crop, but the grapes are still green and very hard and and not one single one is purple.
What can/must I do to save this beautiful/delicious grape ?
Thank you in advance.

Several factors could be responsible for the uneven ripening of the berries within a cluster. Possible causes are over-cropping (too many grape clusters on the vine), a potassium deficiency, moisture stress, not enough sunlight, or weed control spray sprayed nearby.
Over-cropping is the most common cause for home gardeners. An average grapevine may have 200 to 300 buds which are capable of producing fruit. If grapevines are not pruned properly in late winter, the number of fruit clusters may be excessive. The vine is unable to ripen the large crop properly, resulting in uneven ripening of the berries within the clusters. Since you mention you had them many years, possibly they will need some pruning on the vines and fertilizing.

What is the spacing between concord seedless grapes - between vines and between rows? Can the be planted in the same areas as blueberries and raspberries?
Question by: Tom Wilson on Mar 8, 2023, 9:12 AM
Vine spacing within the row can be 6 to 9 feet apart. A typical spacing might be 8 feet apart to accommodate normal growth. Raspberries like to spread, so be sure there is enough spacing between the raspberries and the grapes if planting in the same area.
