We don't grow peas anymore. We used to, but you need to be very careful and harvest exactly when it's time. We could not always help my dad in harvesting and it became difficult. The other thing that has contributed to stopping growing them is the type of peas. You buy seeds, they promise you the best quality, then when it's harvest time you see it's not what you wanted. So it's not worth it, rather buy it frozen.
