It seems to me that there is this common misconception that peas, peas, peas -- should be planted in cold soil. But notice, peas take 36 days at 41Ã‚Â°F! And realize that peas are planted deeper than lettuce or spinach where the soil takes more days to warm in the early spring. When I see how early some folks sow pea seed I often ask myself why they don't plant later when something like a month wait won't be required.
The link you post has the guy saying that sowing without pre-sprouting pea seed results in 15% germination with the remainder rotting. That must be an entirely different gardening environment to what I am used to .
