how to grow seeds in a pot

Seed-starting containers should be clean, measure at least 2-3 inches deep and have drainage holes. They can be plastic pots, cell packs, peat pots, plastic flats, yogurt cups, even eggshells. As long as they are clean (soak in a 9 parts water to one part household bleach for 10 minutes), the options are endless. You can also buy seed-starting kits, but don’t invest a lot of money until you’re sure you’ll be starting seeds every year. If you start seeds in very small containers or plastic flats, you’ll need to transplant seedlings into slightly larger pots once they have their first set of true leaves. Keep in mind that flats and pots take up room, so make sure you have enough sunny space for all the seedlings you start.

3. Plant at the proper depth.
You’ll find the proper planting depth on the seed packet. The general rule of thumb is to cover seeds with soil equal to three times their thickness – but be sure to read the seed packet planting instructions carefully. Some seeds, including certain lettuces and snapdragons, need light to germinate and should rest on the soil surface but still be in good contact with moist soil. Gentle tamping after sowing will help. After planting your seeds, use a spray bottle to wet the soil again.

Planting a seed in a pot is a great way to start both indoor and outdoor plants. To get started, you’ll need a seed starting tray or a large pot with drainage holes. Fill your starting tray or pot with a soil designed for starting seeds, dampen the soil, and plant your seeds in it. Follow the instructions on your seed packet for how deep and far apart your seeds should be. After you plant your seeds, keep them somewhere warm where they’ll receive plenty of sunlight. Water the soil whenever it starts to dry and turn the tray or pot 90 degrees every day to help your seeds grow.

Cardboard egg cartons work well, but you can also repurpose cut-down milk jugs, yogurt cups, and disposable pans. You can also make your own seed starter pots from materials like newspaper and paper mache.

If it's your first time starting seeds indoors in winter, it's best to go small. Pick just one or two types that are easy to grow from seed like these favorite annuals:
