Choice of hedge trees
The choice of which hedge tree to plant depends very much on the function that this element must have. If the function of the hedge trees is to protect the garden or part of it, thorny and compact shrubs should be planted. Species such as the pyracantha which also produces beautiful colored berries are particularly suitable, even the Japanese quince forms a thick intrigue of branches. Berberis, fuchsias, potentillas, deutzia are good for informal hedges, a variety to cultivate as when they are planted as single shrubs. For formal linear and regular cut hedges, choose any type of conifer. The yew, the tuja and the cypress of Leyland, the hornbeam, the laurel, are very common species, which require only one seasonal pruning, very resistant to the winter climate, they produce a thick and luxuriant crown all year round.
Pruning of trees for hedges
Pruning is an essential operation. The width of the hedges, even if with a luxuriant foliage, must not exceed 60 cm, hedges that are too wide will require excessive maintenance and care work and will take up too much space. In formal hedges the base must always be wider than the top of the tree, to prevent the bottom from being left bare. The luxuriant top will in fact be the shadow of the base and this could create an unpleasant aesthetic effect. In any case, always start from the bottom and sides, proceed in the cut always in the same direction and stop every now and then to check the work. Use hedge trimmers to prune small-leaf species and all conifers, for other shrubs use long-blade hedge shears or short-blade shears; clean and oil the tool blade after each pruning.
