How to Plant Seed Indoors

Overview

Most gardeners dream of having a greenhouse someday in their backyards. Until that day comes, the next best place to start seeds is in the house. Indoors you can control light and temperature, and you won't have to worry about birds and other critters munching on your seeds. If you plan to eventually move your plants outdoors, start the seeding process three to four weeks prior to the last frost in your area. That way your plants will have a good, healthy head and some strong root growth prior to being moved outdoors.

Step 1

Fill a seeding tray with seed starting mix to within 1/2 inch of the top of the tray.

Step 2

Water the soil well and allow the tray to sit, draining for 30 minutes.

Step 3

Sow your seeds according to the package directions. Generally, larger seeds, unless directed otherwise by the seed distributor, should be planted one half inch deep. Smaller seeds can be planted 1/4 inch into the soil. Space your seeds 1/2 inch apart.

Step 4

Place the seeding tray in a transparent plastic bag and secure the bag with a twist tie or a rubber band. The plastic should remain 1 inch over the surface of the soil.

Step 5

Place the bagged tray in a location that is light, but out of direct sunlight, and where the temperature is 70 to 75 degrees F in the daytime and no cooler than 60 degrees F at night.

Step 6

Check the soil daily to make sure that it isn't drying out. If it appears dry, use a misting bottle to lightly mist the soil. Be careful not to let the soil get soggy or the seeds will rot.

Step 7

Remove the tray from the bag when the seeds begin to sprout.
