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 can be grown as a spring or fall crop in most zones warmer than zone 2, and can be grown as a winter crop in frost-free climates. Fall plantings should be done 10 to 12 weeks before first fall frost. Peas require 55 to 80 days for maturity and fall crops will not mature after frost. Harvest shelling peas when pods are plump and full, and peas tender. Harvest snow peas while pods are flat, with only a hint of the pea within.
