I know this is not the right time of year but this is a "rescue mission" so I have no choice... I am going to dig up some mature elderberries and choke cherries and transplant them in an adjacent state. They will be dug up, driven about 8 hrs and probably won't go in the ground 'til the following day. Could someone give me tips on increasing their chance of survival? Would soaking in a bucket overnight be beneficial? Some sources I found say soak, others say don't....any tips would be greatly appreciated! Thank-you!
