I’m in a similar boat; my jujubes will be coming in a month though. From what I heard, just plant them as soon as you can dig the hole. https://extension.psu.edu/spring-fruit-tree-planting-tips-for-the-home-garden and Planting trees
- Open the package and report damage
- Place the tree somewhere cold and where the roots can remain not dry (i.e., covered in damp soil, sawdust, hay, etc.). They can remain like this for a few days
2a) Soak the roots for a few hours in water before planting - Dig a hole big enough to not need to bend the roots much, and deep enough such that the bud union will be 2-3 inches off the ground after settling. For Jujubes, it’s roughly as big as the root ball and a little wider. You’ll need to go much wider for apples.
- Point the roots in the direction of prevailing winds (but I think branch direction may also matter, someone smarter than me can chime in)
- add 4-6 inches of soil and jiggle the tree up and down to reduce air pockets. For some trees, don’t do this because their roots are sensitive (like a pawpaw).
- Fill the hole and tramp the soil firm
6b) Optional: Stake - Add some water (5 gal). Jujubes are pretty drought tolerant, so this may not be necessary, but also I think it’s generally a good rule of thumb to water most trees after transplanting.
- The extension suggests adding fertilizer, but I’m not sure; I think it’s best to skip fertilizing jujubes when planted. Someone smarter than me can answer that.
- Add a tree guard
- Prune to keep the tree 1:1 with roots for bare-root trees for jujubes
- Mulch (don’t let it touch the trunk)
