Q:

Is it too late to prune my grapes being it is mid March? I didn't have a chance and it is huge - about 7 years mature and I live in Grants Pass.

- Josephine County, Oregon
A:

Grapes can be pruned any time of the year. The later you prune, the greater the chances of delaying budbreak. This may not be ideal in regions (e.g. Southern Oregon) that have a relatively short growing season, especially for late-maturing cultivars. After budbreak, care has to be taken when tying the canes (if cane pruning) since buds can be knocked off.
