L.H. Bailey on Pruning

Of all the operations connected with horticulture, pruning, shaping, and training bring the person into closest contact and sympathy with the plant. One directs and cares for the plant tenderly and thoughtfully, working out his ideas as he would in the training and guiding of a child. There are some persons, to be sure, who cannot feel this sympathetic contact with a plant: they are the ones who, if they prune at all, use an axe or machete or a corn-knife. If a person cannot love a plant after he has pruned it, then he has either done a poor job or is devoid of emotion. It is a pleasure to till the soil and to smell the fresh crumbly earth, but the earth does not grow; it is still a clod. The plant responds to every affectionate touch. - L.H. Bailey, The Pruning Manual
