If you are looking for books on propagation, many national horticultural societies have their thorough books on the topic. In the USA, ours would be the "American Horticultural Society Plant Propagation"; in England, their book would be the "Royal Horticultural Society Plant Propagation". Just insert your national horticultural society's name in "_________ Plant Propagation" and something might appear online.

Arizona's MG Manual is online for the public to use. Then, Organic Gardening's website has information on

Iken Edu's YouTube channel has this cool video explaining artificial plant reproduction:
