Starting seeds is a cost-effective and simple way for gardeners to grow a variety of plants and vegetables in containers, in outdoor gardens or indoor spaces, or to continue as potted plants. By starting with seeds, gardeners can save money compared to buying pre-grown plants from nurseries or garden centers.
Starting your plants from seeds in a good growing medium also offers greater control over the growing process and allows for customization of the garden according to personal preferences.
With a few basic tools and materials, such as seed trays, soil, and light sources, anyone can easily start seeds and grow their own plants. Whether you have a large outdoor garden or a small indoor space, starting seeds is a great way to save money.
You will also enjoy the rewards of growing your own plants from store bought seeds or your own seed that you harvested the previous growing season!
We're going to look at the best tools for starting seeds indoors, specifically, the best seed starting mixes.
Best Soil For Seed Starting
Before we give you the best brands and listings for where to buy your seed starting mix, here are some of the things you want to look for:
The best soil for planting seeds is going to be a fine-textured, well-draining potting mix that is specifically formulated for seed starting. Seed starting mixes are designed to be lightweight and porous, allowing for optimal air and water circulation around the delicate roots of seedlings when they start to form.
Seed Starting Mixes
These mixes also typically contain a balanced blend of nutrients that should be readily available to young plants so they can grow into healthy plants!
Seed starting mixes are often made from a combination of materials such as peat moss, vermiculite, perlite, and compost.
Peat moss (think sphagnum peat moss) and vermiculite help to retain moisture and provide aeration, while perlite helps with drainage.
Compost adds nutrients to the mix and supports healthy growth in a potting mix recipe. You can go ahead and compile all of those yourself, and mix them together in a large container an distribute evenly among your trays (yes, you can totally do this, you will save money, but not time.)
DIY Seed Starting Mix Resources
Here are our recommended resources for purchasing those materials to make a homemade potting mix for growing seedlings:
Check price of compost here (or you can use your own compost!)
*If you don't have a backyard composter, you can always use a countertop composter. You put your table scraps in every day, and before you go to bed, press the button and it composts overnight to a dry, grainy compost that you can save.
It's important to note that garden soil is not recommended for seed starting because it may contain pathogens and other harmful organisms that can damage or kill seedlings.
Additionally, garden soil can become compacted and heavy, making it difficult for young roots to grow and develop.
Here is a DIY seed starting mix recipe if you decide to go ahead and make your own. If you are ordering the recommended materials online, feel free to bookmark this page to come back for the recipe!
Homemade Seed Starting Mix Recipe
Homemade Seed Starting Mix Ingredients:
- 2 parts peat moss
- 1 part perlite
- 1 part vermiculite
- 1 part compost
Homemade Seed Starting Mix Directions:
- In a large container or bucket, mix together the peat moss, perlite, and vermiculite until well-combined.
Pro tip: if you are doing this outdoors, a wheelbarrow comes in handy!
- Add the compost to the mix, and continue to stir until it is evenly distributed throughout the mixture.
- Moisten the mixture with water until it is evenly damp but not soaked.
- Fill your seed trays or containers with the seed starting mix and sow your seeds according to their planting depth and spacing requirements.
- Cover the seeds with a thin layer of the seed starting mix, and mist lightly with water to settle the soil around the seeds.
- Place the seed trays in a warm, bright location, and keep the soil evenly moist but not waterlogged until the seeds germinate.
Note: If you prefer a more sustainable alternative to peat moss, you can substitute it with coconut coir.
Coconut coir is a renewable resource that is becoming increasingly popular as a seed starting mix ingredient.
