The peanut is not a true nut. It is actually a legume.
In Ontario, it must be planted in early to mid-May in a light, well drained sandy to sandy-loam soil.
Its' preferred growing environment is hot and dry (a minimum of 3000 corn heat units), and requires little, if any, fertilization due to its unique ability to "fix" its' own nitrogen requirements.
The 18" leafy plant produces small yellow flowers. After pollination a small shoot forms at the base of each flower and pushes into the soil. The process is called "pegging" and continues for most of the season. The "peg" develops into a mature peanut pod by season's end.
