Ramification (botany)
In botany, ramification is the divergence of the stem and limbs of a plant into smaller ones, i.e., trunk into branches, branches into increasingly smaller branches, and so on. Gardeners stimulate the process of ramification through pruning, thereby making trees, shrubs, and other plants bushier and denser. Short internodes (the section of stem between nodes, i.e., areas where leaves are produced) help increase ramification in those plants that form branches at these nodes. Long internodes (which may be the result of over-watering, the over-use of fertilizer, or a seasonal "growth spurt") decrease a gardener's ability to induce ramification in a plant. A high degree of ramification is essential for the creation of topiary as it enables the topiary artist to carve a bush or hedge into a shape with an even surface. Ramification is also essential to practitioners of the art of bonsai as it helps re-create the form and habit of a full-size tree in a small tree grown in a containe ...

Bonsai
Bonsai (; , ) is the Japanese art of Horticulture, growing and shaping miniature trees in containers, with a long documented history of influences and native Japanese development over a thousand years, and with unique aesthetics, cultural history, and terminology derived from its evolution in Japan. Similar arts exist in other cultures, including Korea's ''bunjae'', the Chinese art of ''penjing'', and the miniature living landscapes of Vietnamese . The loanword ''bonsai'' has become an Hyponymy and hypernymy, umbrella term in English, attached to many forms of diminutive potted plants, and also on occasion to other living and non-living things. According to Stephen Orr in ''The New York Times'', "[i]n the West, the word is used to describe virtually all miniature container trees, whether they are authentically trained bonsai or just small rooted cuttings. Technically, though, the term should be reserved for plants that are grown in shallow containers following the precise tenet ...
