Grapevine Cuttings and Propigation concerns
I am trying to start some grapevines from cuttings and I keep seeing several different how to's but just not sure one says cut-rooting hormone-stick in the ground- keep moist- (fine in cold weather just let them do thier thing) the other says cut-rooting hormone- wrap in napkin- wet- bag in fridge- pull out later- callous and roots should be there done then the next one is put in a jar of water and wait till roots form then the final way cut-rooting hormone- wrap in napkin- wet- put in a warm area (70-90) keep wet and then should root.
now my problem is who do I believe what works best now our current temps outside at night is mid 30's and durring the day its between 50-60's and sunny out side. So what I have done is I took the cuttings trimmed them down to the proper size I did strip a little bit of the bark off the bottom of the cutting (exposing the green cambium (i believe that is what it is called) and put the bottom 2 inches in the water and then dipped them into rooting hormone and I put them in a pot of potting soil then I watered the potting soil then I split up the plants half went outside in a sunny area on a table (at night I cover them with other pots to keep them a little protected at night) and the other half went into an old clod frame greenhouse (it is not in the best of shape a hole in the back where the seam of the vinyl cover split a little bit but they are slightly in a protected area) but I just am not sure if that is ok or not because I hear other people saying keep them protected and in temp's in the 70-90 area clearly they are not in those temps outside in the greenhouse durring the day they get into the low 70's but thats it so I just want others opinions on if they will be ok outside with my temps I got 40 cuttings out there and really dont want to loose them. I keep thinking they should be ok because alot of methods have the cuttings in the cold like the keep in the fridge for storage basically I got them in a natural fridge and as the weather heats up they should grow right i dont know help Oh they are Concord's Catabawa's Crimson's Temperano's
