Grafting over a Mariana Plum with danger of Frost in the Future:

General Fruit Growing
#1

Hello,

I always get such amazing advice on this forum and it’s helped me tremendously in my orchard. I have a 4 year old overgrown Mariana rootstock that grew into its own tree. I pruned it heavily last summer to get it ready to be grafted over with 10 hybrid plums this season.
I was going to graft tomorrow (Saturday), here’s my forecast:

My question is this, knowing there could be a frost event in 7 days time would I be courting disaster to graft tomorrow? Has anyone grafted plums and had them survive a light frost within a week of grafting?

Thanks everyone!

I decided to go ahead and test how well the grafting might work with some of my hybrid plum varieties. Did 7 on the big Marianna tree:

We’ll see how they do.

I’ll graft another set in two weeks after the weather warms more.

I’m sure they’ll be fine. I grafted Apple, plum and plumcot today. My scions were bigger than the host so I’m not sure how it went…
