Chip the Seed
Sweet pea seeds have a hard shell, and unless water can penetrate it, the seeds won't germinate. To ensure the seed absorbs water, use a sharp knife or nail clippers to carefully nick it opposite the "eye" (small, round scar) and remove a small piece of the seed coat.
In fall in warm climates, fill trays or pots with seed soil and sow the seeds 1/2 inch deep. Keep the seedlings in a cool greenhouse or cold frame until the following spring, only providing extra heat during severe frosts. In mid-spring, remove the tip of the main shoot from each seedling.
If you sow sweet peas in early spring, grow the seedlings indoors, or in a warm greenhouse, at 58–62 degrees F. When they reach 4-6 inches high, remove the tips down to the first set of leaves. Pinching out the tips like this encourages side shoots to form.
