Girdling (cincturing) is the removal of a thin ring of bark from the trunk or cane to temporarily stop downward movement of sugars, which can improve berry size and earliness in table grapes. It is usually done around the fruit set to early berry development stage on healthy vigorous vines, using a clean girdling knife to take a narrow ring without cutting too deep into the wood. Done wrong or too wide it can weaken or kill the vine, so it is a skilled operation that should only be done on strong vines and never every year on the same weak vine. It is often combined with judicious thinning and gibberellic acid sprays under expert guidance, with attention to residue limits for export grapes. Confirm the exact ring width, timing, and whether girdling suits your variety with your local KVK or grape research station.

Only our most experienced worker does girdling on the export plot. On thin or stressed vines we skip it completely because the loss is not worth it.

We girdle on the cane just below the bunch zone rather than the main trunk, so if anything goes wrong we lose only that cane and not the whole vine. Keep the knife clean and sharp so the ring is neat and heals over in a few weeks. On Thompson seedless this gave us a clear size bump in good years.
