when do you plant sweet peas
1 Early sowing is one of the secrets of sweet peas. 2  In Zone 7 or colder, plant them in very late winter or early spring as soon as the soil is dry enough to work. ( 3 Do not wait until frost.) In the coldest parts of the country, get a jump on the season by starting sweet peas indoors in six-packs or Jiffy pots.
