How to Plant Seeds Inside


Planting seeds inside is more often done in short growing season locations. By starting seeds indoors, it will give you a jump on vegetable or flower growth. By the time the last frost in your location has passed, you will be planting seedlings, rather than starting with new seeds. Use commercial potting soil when planting seeds inside, as it is assured to be without any plant diseases or stray seeds that could later pop up in your garden.

Step 1

Collect planting containers. You may purchase planting trays or containers from the garden center, but it is not necessary. Use paper cups or pre-used food containers, such as yogurt, cottage cheese or sour cream containers. Just make sure they are washed thoroughly.

Step 2

Fill the containers with potting soil, to ¼ to ½ inch from the top. Moisten the soil with a water bottle sprayer and stir it about. Do not add so much water that it is sopping. You want it to be just moist.

Step 3

Read the manufacturer's suggestion on the back of the seed pack for planting depth suggestions. Each seed variety is different. Plant the seeds. Push soil over the top of the seed hole, gently.

Step 4

Mark each container as to the name of the plant seed in it. It's easy to forget if you are planting more than one type of seed.

Step 5

Place the seed containers in a tray and place them by a sunny window on the east or west side of your house.

Step 6

Mist the seed planted container soil as they begin to dry. Again, only spray enough water to moisten the soil. Soon the seeds will germinate (sprout through the top of the soil).

Step 7

Plant your seedlings outdoors after the weather begins to warm and the last frost for your area has passed.
