Temporary storage of a bare root tree
I was expecting to get a bare root peach tree today or tommorow (fri or sat) with the intention of planting it this weekend. Unfortunately, it looks like it won't arrive until Monday, which means it will have spent 7 days in a box in transit.
My problem is that my house and my orchard are about 90 minutes apart and it's unlikely that I will be able to plant the tree until the following weekend or about 13 days from when it was packaged and shippped.
My question is how should I best store the tree at my home from Monday until Friday/Saturday when I take it to the orchard location?
I got somewhat contradictory advice from the nursery. They said to remove it from the box and hill it in until I was ready to plant, but they also said to try to keep it from breaking dormancy. I'm worried that if I hill it in, it will be exposed to the sun and semi-warm temperatures (50s during the day, 30s at night) and it will break dormancy. So to combat that, I was thinking of keeping it in the box, in my garage when the temperature will be more constant and will stay cooler.
What should I do if I can't get it in the ground for a week?
