How to Start Seeds Indoors
You might be itching to get your garden going, but chances are the outdoor sowing season is still a few weeks away. Well no worries, you can start your seeds indoors several weeks before the final frost of the season!
By starting your seeds indoors, you can get a jump on the growing season while saving some money in the process. Here is what you need to know to start seeds indoors.
First, let’s take a look at what you will need:
- Seed starters (you can use anything: yogurt cups, egg carton cups, egg shells, K-cups…etc.)
- Potting soil
- Seeds
- Spray bottle
- Cookie sheets or a tray of some sort
- Wood craft sticks
- Marker
- Clear Plastic Wrap

I’ve linked to some items on Amazon for convenience, but you can gather supplies from anywhere to fit your budget.
A good rule of thumb for when to start your seeds is 4 weeks before the last frost of the season. This will vary depending where you live, so consult The Farmer’s Almanac to find out when the perfect planting time is for you.
DIRECTIONS:
- Begin by placing the seed starter cups on the cookie sheet or tray. This way, the surface under the cups is protected and you can easily move them if you need to. Also, make sure the containers you choose have drainage holes.
- Fill each cup 3/4 of the way full with nutrient rich potting soil. Seedlings need a light, airy soil mix that drains well. You can buy a seed starting mix at a garden center or make your own by mixing equal parts peat moss, vermiculite, and perlite.
- Plant the seeds: Follow the instructions on the seed packet for planting depth and spacing. In general, plant the seeds twice as deep as their diameter.
- Cover the seeds with soil and mist the area with your spray bottle. Misting is easier and cleaner than a watering can, plus it will keep you from over watering.
- Use the wood craft sticks and marker to make plant markers for the seedlings so you know what they are once they start growing.
- Pull a sheet of plastic wrap over the top of the seed starters. This will allow light in but will help the plants retain heat. NOTE: You will need to remove the plastic wrap every few days to mist the soil to keep it moist. Just be sure to return the plastic when you are done.
- Place your seed starters in a window where they will get at least 6 hours of sun per day. If you don’t have an area where this is possible, a sun lamp will work.
- As soon as you see sprouting, remove the plastic wrap. Continue to water every few days and keep the soil moist at all times.
In just a few weeks, your seeds will be seedlings and soon they will be ready to get transplanted outside. Be sure the threat of frost has passed and you follow package directions when transplanting.

I’m new to all of this. My son & I are going to plant tomato seeds, but I am not sure what kind of potting soil we should get. Do you have any suggestions? Thank for the post.
