I know that nothing beats hands-on experience on Plant Propagation but a good reference material is handy for those who want to learn more.
One of the most exciting projects that a gardener can undertake is to propagate his own plants. Few experiences can match the thrill and awe felt by a gardener who has successfully germinated an even crop of bedding plant seedlings or a particularly difficult woody plant seed, or who has managed to root a cutting or unite two grafted parts of a plant.

Plant propagation has been practiced ever since early man abandoned his itinerant life and settled down on the land, where he started to grow his own food. The techniques of vegetative propagation developed in such ancient civilizations as those of the Babylonians and the Chinese are still relevant and in use in the twentieth century.
