I am grafting for the first time, and am one of those ultra paranoid types. I may be overthinking this. I ordered scions and rootstocks from two different sources, and received part of my order today The majority of the scions and half my rootstocks are here. The rootstocks are pushing buds, a couple have tiny leaves popping out at the top… and it’s still below freezing where I am in zone 4. Our daytime temps are mid 30’s but we have been in the teens overnight. The scions look pretty dormant yet.
My question is, can I put the rootstocks in the fridge for a bit or am I committed to grafting now seeing they are budding? The rootstocks are apple, EMLA 111 and Bud 118. I wasn’t expecting them quite this early, so I need to stall until Wednesday at the earliest because my wax, parafilm, etc. won’t be here until Wednesday. Can I hold them in the fridge for a bit or should I graft on Wednesday? Thanks in advance.
