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.
The pea plant can tolerate an occasional frost, although new flowers or pods may be damaged. Soil temperatures must also be considered. Studies have shown that peas may take as long as 36 days to germinate when sown in cold soil (below 40 degrees F.). Germination takes about 9 days at a soil temperature of 50 degrees F. At 68 degrees F., germination takes 7 days.
