My Niagra grape vine is doing very well this year and has put out

there any merit in what I've been told ?

Where are you that you would be harvesting a North American grape species,
Vitis labrusca, in May?

Not harvesting yet. That'll happen end of July to early August. We live
in the Sandhills of NC. Temps started out high early on but have cooled
off a bit lately bringing much needed rains. Grapes are thriving.

Question aside, the answer is no.

The vine continues to store starches in its roots, made from
photosynthesis, to be used during the following budding season. If you
want to reduce next year's crop, cutting off the vines while they are
still in photosynthesis is an effective measure.

This vine just barely produces 5 gallons of wine. I need each and every
cluster.

If you want larger fruit, give them more water.

Will do so ...

If you want better quality, drop (cut off) a third of the clusters.


How many buds are you leaving when you prune?

I cut each cane back to two buds.

Thanks for the reply
