If you've had trouble getting pea seeds to germinate and grow in your garden, try soaking the seeds in a solution of vitamin C or folic acid before planting. Researchers at the University of Massachusetts, found that pea seeds soaked in a solution of either vitamin C or folic acid prior to planting germinated better than pea seeds soaked in plain water, and after 10 days of growth the seedlings were 40 percent taller and their roots were 20 percent longer.
The experiment was terminated after 10 days, so it's not clear if the results would last throughout the pea's growth cycle and if there would be any benefit from applying vitamin C or folic acid once the peas germinate. However, these supplements will get your peas off to a quick start. Vitamin C and folic acid are commonly found as dietary supplements in health food stores.
