grape cuttings grew buds but then stopped??

So trying my luck with growing some grape cuttings from my bosses vineyard.
The cuttings were all cut back to 3-4 nodes and either planted small pots or kept in water to root. All kept inside on a sunny windowsill around 20degrees.

All of them produced buds on the nodes, however now after nearly 2 months nothing has happened.

Thinking maybe i should wrap them in a damp towel and refrigerate for a week or so to force hibernation and then try again? or cut back a further node and see if that encourages growth?
Any suggestions would be appreciated!

 

The only time I got my grape cuttings to root I hadn't intended to!  I'd heard that you could keep grape bunches fresh by cutting a bit of branch with them and standing it in water in a cool place.  I therefore had a load of bunches in a couple of pint glasses on my window sill over winter, and two months later several of them were rooting.  It didn't work this winter, I don't know what the difference might be.  I'm quite keen in propagating my other grape variety.  For information our house is pretty cool, so the window sills probably get down to 5 degrees C or so overnight and maybe 12 degrees C during the day.  I'm not sure what temperature scale you're using? If Celsius then they may have been too warm, so refrigeration may help.  Do they still look alive?

I wouldn't worry about the delay, my cuttings do the same thing. They seem to be slower to open than the established vines, and may already be putting their energy into forming some roots. If they are moved, it could disturb the root formation.

It looks like the bud that I can see in the picture is starting to slightly swell, which is a good sign, with that reddish bronze color.

Good luck and hope your cuttings root for you!

Thanks for the quick reply, I thought that but I'm a bit worried as they have had no changes in the buds that have grown for I would say over a month now...I had 2 other Cuttings that I planted much later and leafed wlthin a week or two...I will keep waiting and cross my fingers 🤞🤞

Maybe you can help with another question... I had 2 other Cuttings that I rooted and they leafed reallx quickly, however they were a spur of the moment idea (found them walking through my bosses vineyard and thought why not) but I put them in a pot together and then when they leafed the leaves grew in to each other. I decided to report in to their own pots to allow room for growth however within 2 days all leaves were dead and fell off... The had 1 or 2 really thick roots still but appear dead.  Is there any chance of these resprouting with time, or do I need to cut back and re plant or are they likely just dead? Again any advice would be appreciated.

I'm using Celcius, some where kept outside over the winter (in a small homemade glasshouse, getting down to -5c. Some were kept inside on the windowsill always around 15-20c, so there was a mix of cold and warm (there are about 12 cuttings in total). If I get nothing in a few weeks I will try refrigeration 😁

Since it sounds like they have a good root or two on them, I think there's a good chance they'll bounce back. I'd put them on the north side of a building where they won't get any direct sunlight and water them but not too much, as grapes don't seem to care for a lot of water.

Hope they bounce back for you Tim!
