Answer
Sweet peas require regular watering, especially as the temperature increases. They prefer a somewhat rich soil and can be fed monthly with a fertilizer high in potassium, as used for tomatoes. Adding a bit of blood meal to the soil is thought to help keep the stems long and suitable for cutting.

There are few pests or problems associated with sweet peas. They are usually done in by the heat. Ofcourse if the temperature drops below freezing the frost will kill the plant. But since they are usually planted after the last frost the heat in the summer will be their down fall.
