Before and after grafting
There's a lot of information out there about grafting, but not a lot on before and after care.
So, I got my apple rootstock from Raintree and budwood from Nick Botner.
The budwood I understand, keep it cool and don't let it dry out. What do I do with the rootstock? I understand that I want the sap flowing before I graft.
How do I know when it's flowing? When the buds start to swell? Maybe put the rootstock in damp saw dust or a potting mix until I see the appropriate signs?
So I've done my grafting, now what? Back in the sawdust/potting mix while the grafts heal? Put them in a cool place or a warm place? Sun or no sun? For how long?
