Grapes from seed

Hello everyone. Has anyone tried growing grapes from seed with any luck? I am trying this over the winter.I know grapes really aren't tropical but I really didn't know where to post about them. I am trying the red globes and blue concord's. I am using the fridge method for early stratifying, to get a jump start on spring planting.

Grape seeds are not, generally speaking, easy to germinate, as they have a very high proportion of dormancy. The only usual reason for growing from seed is following intentional cross pollination to develop a new variety. Gape seeds do not produce true. I don't have actual figures, but I would guess that over 99% of grape propagation is by clonal methods (cuttings, grafting, micropropagation).

Propagators who do grow from seed have chemicals and equipment that you are unlikely to have (gibberellic acid - GA3, and climate control cabinets for daily alternating temperatures for 6 weeks), but some that you can approximate.

Try refrigerating for 90 to 120 days(1-5 deg C), followed by warm stratification at 30 to 36 deg C for 2 days then soak in 0.5M hydrogen peroxide for 24 hours, then germinate at 30 deg C with 12/12 hours light /dark. Well drained, moist potting soil or a home blend of 1:1:1 sand peat perlite will work fine.

As for timing, once they have sprouted you must be able to provide them with Spring weather, either the real thing or a greenhouse/ growing room. Plant them out well after the danger of frost has passed.

Hi frosty - - from experience they need a bit of a chill factor - - the supermarket or greengrocers refrigerator is usually enough before you buy them - - and then to propogate they need warmth and moisture. I have growing "red globe" - an australian supermarket variety - a large red sweet eating grape. It grew in a pot before transplanting into the ground. We have natural warmth and humidity on the Sunshine Coast in Australia so you may have to try and replicate that.
