Perennial

A plant that grows year after year without reseeding.

Permaculture

Founded on the idea that the farm should mimic natural ecosystems, permaculture sees each element as effecting every other element. Design is very important in this model as the changing conditions in one part of the farm will effect the other parts. Effective use of this technique creates a sustainable environment that minimizes outside inputs, depending instead on the strategic use and placement of existing elements.

Pesticides

Pyrethrin

An oily, naturally occurring insecticide found in plants such as the chrysanthemum. Can be used in organic agriculture.
