I have heard many people bad mouth "mail order" or bare root plant materials over the years but I believe that they have their place and if properly planted and cared for can actually have some advantages.
The first thing that you will need to know is that now is the time to order the bare root plants. Do not wait until late spring because the nurseries will have already sold their plants and if nothing else varieties will be very limited. Most good nurseries have been around for enough years to make good estimates on the number plants that they will need to sell and this fact means that you need to plan ahead if you want to take advantage of this kind of plant shopping.
The bare root tree, shrub or bramble arrives in a cardboard box wrapped in a plastic bag with some moist paper towels loosely wrapped around the roots. The stock is usually dormant and may have a rubber band securing the bag around the trunk to keep the moisture in the bag. It is best to coordinate with a bare root nursery that specializes in this type of plant material and has a good track record. The timing of the shipment is one of the main keys to success. Your lines of communication with the nursery will need to be open and a clear understanding of the weather in transit and the conditions where you are will be essential for successful plants.
When the nursery ships your material you will need to go out that day and purchase liquid rooting hormone in a large container. You will want a quart for every twenty or so plants you put into the ground. You will also need to go out and place markers for each of the plants exactly where you want to dig the holes. I do not pre-dig the holes because I do not want to dry out the soil in the whole and digging the dirt the day the plants arrive one-by-one seems to work very, very well.
DO NOT BACK FILL THE HOLES WITH SOIL OTHER THAN WHAT CAME OUT OF THE HOLE THIS WILL CAUSE THE ROOTS OF THE PLANT TO BIND WHEN THEY ENCOUNTER THE BOUNDARY BETWEEN THE FANCY PLANTERS MIX THAT YOU PURCHASED AND REALITY!!
When the plants arrive, unpack them immediately and soak the roots in water deep enough to submerge the roots. You will want to soak these plants for about 24 hours. At this point, you will need to grab a sharp spade and one by one dig holes and plant the materials.
Grab the trunk of the tree or shrub so that the graft is just above the top of your fist. Place your elbow on the edge of the hole so that the roots drop into the deepest portion of the hole. If the roots touch or bend at all you need to dig deeper. When the roots no longer touch after adjusting the hole then you will begin immediately pushing the dirt from the tailings into and around the roots gently without compacting. When the hole is full the graft should be one fist (@ 4" above the ground.
Water the plant heavily and mix a one gallon bucket to the specifications listed on the label. Each plant gets one gallon of mixed rooting hormone.
At this point you will need to protect the plant from deer, rabbits and dogs. But if you can do this you will succeed and that is definitely the point of gardening - success!
