Definition - What does Tiller mean?
A tiller is a botanical term that may refer to a stalk or sprout of a plant that emerges below the main stem, often near the plant’s base. It's predominantly used in reference to monocotyledons such as grasses or grains. The tiller is one of three different types of branches of grasses in addition to the main stem, along with stolons and rhizomes. Each tiller has its own root system and is capable of surviving if pulled away from the parent plant.
The term “crown” as it relates to monocots, is the point at which the roots of the plant meet the tillers.

Tiller may also refer to a device used in the cultivation of the soil, such as in “roto-tiller”. When in reference to a garden or farm implement, a tiller may be a handheld tool, a self-propelled device on wheels that the operator walks behind or an attachment pulled by means of an animal or machine such as a tractor. Tilling generally turns over the top several inches of soil and is often used to incorporate amendments into the soil.
It may also be performed as a non-chemical strategy of weed control. Plowing by contrast, is generally a turning or moving of the soil deeper than tilling.
