Starting garden vegetables indoors before they would normally be planted outside in the garden gives them a chance to grow healthy and strong in controlled conditions. Peas are usually a vegetable that isn't started indoors, as it can be planted in early spring when the weather outside is still quite cool. If the soil is overly wet from rain or excessive snow melt, the pea seeds may rot in the ground. In this case, you may have more success if your peas are started inside instead.
Fill a bowl with room-temperature water. Place the pea seeds in the water and allow them to soak overnight.
Fill individual peat pots with a quality potting mix. Peat pots are made of compressed peat, allowing them to be direct planted in the garden bed without disturbing the pea plant's roots. Place the filled pots in a drip tray after filling them with soil.
Dust the seeds with an inoculate, available from garden centers and other seed providers. Inoculate helps the roots to produce nitrogen. Place the inoculate in a small bowl and roll each seed in it so the surface is dusted in the inoculate powder.
Sow two seeds per pot. Sow them ¼-inch deep and cover them loosely with soil.
Pour water into the tray so it is absorbed up through the bottom of the peat pots. Set them in a 75 F room to germinate, which takes approximately seven days.
Move the pots to a 65 F location once sprouts appear. Place them in a sunny window or under grow lights for 12 hours a day.
Thin the seedlings to one per pot once they are a week old. Pluck out the weaker seedling, leaving only the stronger one in each pot.
Transplant outside once the ground has begun to dry and is no longer soggy, preferably within two to three weeks of starting the seeds. Alternately, place two to three pea plants into a container with a stake in it and place it outside to grow on a patio or balcony.
