Beautiful sweet peas add color to your garden and fill in bare areas along walls and fences. Planted in the spring, sweet pea seeds can go right into the ground or you can soak them ahead of time. Soaking helps aid in germination and shortens germination time.
Rub each seed between two pieces of medium-grade sandpaper for a few seconds to scrape, or scarify, the seed coat to allow moisture to enter the seed.
Wet two paper towels thoroughly to dampen them throughout and spread the paper towels out flat one on top of the other.
Set your scarified seeds on one half of the paper towel. Try not to let the seeds touch but get them close enough that they all fit. Fold the paper towel over the seeds.
Slip the paper towel into a plastic bag, being careful not to dump out seeds. Seal the bag and set it in a cabinet overnight where it won't be disturbed.
Remove the seeds and plant them into soil outside. Sweet peas prefer being planted 1 inch deep and 3 inches apart.
