How long can snow peas flower when it’s 90 degrees outside? Not very long, indeed.
Snow peas are considered an early season garden plant because they do well in cool weather. They stop flowering when the heat becomes unbearable.
The first planting of snow peas was a bust. There was very little germination of seeds that were 3 years old, so more was planted with newer seed in the hopes that we weren’t too late to get a crop in while the weather was still on the cool side.
