Peat pots allow you to plant your seeds and then place the whole pot in the outdoor soil. The pots are biodegradable, made from peat and wood fiber, and are easy to use and good for the environment. Many brands also contain soluble fertilizer. By transplanting the vegetable seedling to your garden, without having to remove it from the container, you eliminate much of the stress on the plant.
Fill your peat pots with commercial potting soil to ¼ inch from the top. This potting soil is perfect for starting any type of seed, as it is filtered of any harmful diseases or weed seeds.
Place the peat pots in a plastic or metal tray (about 18 pots to a tray). Pour a quart of water in the bottom of the tray. Let the pots set overnight, absorbing the water.
Make an indentation in the center of the soil in each pot. Drop a seed in each one. The depth of the hole will depend on the size of the seed. Usually the back of the seed packet will tell you how deep it should be planted. A good general rule is to plant a seed three times its height.
Gently cover the seeds with soil. Place the tray of vegetable seed peat pots in a sunny window, indoors. Add a quart of water to the tray, as it becomes dry at the bottom.
Place your seedlings outdoors in a protected location---such as a covered porch or patio---for about three or four days, after all threat of frost has passed in your region. Increase the amount of sun your plants receive each day, by moving them. Move them into the morning sun for an hour, then two hours, and so on. This will acclimate your vegetable seedlings to the new environment. This process is called hardening.
Cut slits down the sides of the peat pot and an "X" at the bottom. This will help the tender roots grow out of the pot. Plant the entire pot into the outside garden soil. Make sure the pot is completely covered with soil. You should have already worked your soil so it is soft and amended, if needed. Water your new garden as needed to keep the soil moist.
