A large variety of peas are grown in the United States--from snow peas to English peas. They are a popular food source with a high quantity of various nutrients required for human development and a distinct flavor. They have an annual life cycle and are relatively easy to grow and maintain.
Pea plants require soil that is warmer than 40 degrees Fahrenheit and offers good drainage. Colder soils make it harder for plants to grow and slow down the germination rate of pea seeds.
Pea plants grow best in areas that receive direct sunlight. These areas are usually the parts of the garden that thaw first in spring. Peas grown in full sunlight will develop fruits with lower sugar content.
Peas are cool-weather plants that can survive during slight frost temperatures of no less than 40 degrees. They begin to grow during the cooler parts of early March, but prefer temperatures of 75 degrees Fahrenheit.
Too much moisture will cause wilting within a plant and promote the growth of mildew and fungi. Fungal diseases are likely to attack plant overexposed to moisture and cause the plant to suffer root rot and leaf decay. These diseases are potentially lethal to plants if left untreated.
Peas were one of the first plants to be harvested by humans, according to the National Garden Association, and were originally found in Asia and Easter Europe. Dried pea seeds have been discovered from as far back as the Stone Age.
