Multidetector computed tomography of a saphenous vein.   Bark grafting is a relatively easy and very successful process done only in the spring after the bark begins to slip and the buds are opening.

G rafted seed orchards of Douglas-fir are often subject to tree losses caused by delayed graft incompatibility. When the stock and scion (the grafted branch) are incompatible, the stock and scion wall off the foreign cells with a separation zone of dead, suberized (corky) tissue. To bark graft you will need a grafting knife, grafting compound and either a nail gun with wire nails or electrical tape, either one will do. Bark grafting is best performed in the spring as buds in the orchard are starting to open and the bark of the root stock slips. It can be done successfully up to the 30 days past full bloom.
