Definitions
There are two types of plants. Perennials and Annuals. This terminology is kind of confusing so here are some simple definitions:
- Perennial: Bloom and return each year (for several years)
- Annuals: Bloom only once.
Benefit of Perennials
Wheat is an annual crop that requires burning or clearing fields at harvest time each year. This can lessen the quality of the soil and require more fertilizer.
Perennial crops last for at least two years and do not require clearing fields. Nutrients can remain in the soil. Watch the following short video on a new initiative to substitute wheat with a perennial crop.
