To protect the branches from damage, and make handling the shrub easier, use soft garden string to tie them together. Rake any mulch away from the base and save it for later.
Dig out a spade's width trench around the shrub, to give you room to cut under the rootball, using your spade, to sever any deep anchorage roots. These can be safely cut without harm.
Prepare the new site where you're going to plant the shrub. Dig a planting hole, larger than the rootball, and mix compost and bonemeal fertiliser with the soil at the bottom of the hole.
Some species, such as roses, magnolia, cytisus and daphne particularly resent root disturbance, so try to avoid transplanting those.
Position your shrub in the hole at the same depth as it was planted before, filling around the roots with soil mixed with compost and bonemeal. Firm the soil, add mulch and untie the branches.
