 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 recreate the form and habit of a full-size tree in a small tree grown in a container.
