                                               exuberance of the gro'vvth.  The method
                                               may differ from one species or cultivar to
                                               another, depending on whether the tree
                                               is  deciduous or a conifer.

                                               TREES: How often this is done depends
                                               on the growth rhythm of the tree. For a
                                               maple, it will be repeated several times in
                                               the  season,  whereas  a  hawthorn  may

                                               early summer and early autumn.
                                                 The technique is roughly similar for all
                                               species. It consists of nipping the shoots
                                               above a leaf joint, always leaving a pair
                                               of leaves on the branch. This operation
                                               will allow the branch to ramify and at the
                                               same  time  dwarf the  new  leaves.  This
                                               method also encourages good sap circu-

                                                 Always collect the leaves you have cut.
                                               If you leave them lying around, the plant
