Giardia lamblia is a protozoan (parasite) that is implicated to be the most common non-bacterial causative of diarrhea in North America. Giardia is implicated in 1/4th of all diarrheal diseases in adults in North America.
Peas will sprout in 21 to 30 days if the soil temperature is 38 degrees Fahrenheit and the germination rate, or number of seeds that do sprout, will be low. At temperatures of 65 to 70 F the seeds will sprout within 7 to 14 days and the germination percentage will be in the high 90s for fresh seed.
Peas are categorized by the time they are planted. Cool-weather varieties can be planted in all areas in early spring and in some areas in late summer. They grow best when the temperature stays below 70 degrees. Peas will stop producing pods when they get too hot, but will start producing again when it cools down. That's why peas are considered a cool-weather crop.
