The Magic of Seed-Starting
Coaxing new life out of a seed is one of the highlights of the year for gardeners – right up there with harvesting perfectly ripe vegetables, at least in my opinion. I’ll never tire of watching delicate seedlings break through the soil and stretch towards the light, hopefully not having to stretch too far. And I love the feeling of productivity that starting seeds indoors gives me as winter seems to drag on and on. It’s like a little bit of the life and hope of spring, inside my home.
Starting seeds indoors gives your vegetables, herbs, and flowers a head start so they can grow larger and have better and longer harvests or flowering periods. With a few basic supplies and a little patience, it’s easy and fun to start seeds indoors. As everyone knows, a little tending is good for the soul.
Why Start Seeds Indoors?
There are countless reasons to grow from seed. First, starting vegetables, herbs, or flowers from seed is more cost-effective compared to buying young seedlings. The yield is also higher when starting seeds indoors. As Carrie Spoonemore, co-creator of the Park Seeds From Seed to Spoon app, says, “A package of seeds can provide so many more plants than you could purchase for the same amount.”
Beyond getting more bang for your buck, growing seeds indoors gives you control over your growing conditions. If you live in a region with oppressive winters, seed starting indoors can help you get a jump start on the gardening season, giving your green thumb an outlet during darker days. As Martha Stewart’s experts explain, “Starting from seed also allows you to choose from far more variety than what’s in stock at the local nursery. Paging through seed catalogs and ogling rare varieties might just become your new favorite pastime.”
Timing is Everything
Timing to start seeds indoors depends on what you’re growing and what growing zone you live in. Your zone will give you the approximate date to plant outdoors in your area. Once you know your growing zone, look at the back of your seed packet to see how many days to germination. Now count backwards from the date of planting to determine when to plant.
As Carrie Spoonemore explains, “Most plants need at least six weeks from planting to moving outdoors. Some need to be planted as early as January, so check the seed pack to be sure.”
Choosing the Right Containers
The container you choose influences factors like moisture drainage and root development, which directly impact the growth and health of the seedling. There are fantastic pre-made seed starting trays that are especially great if you’re new to growing plants from seed. As Ryan McEnaney, garden designer and author, says, “They allow for drainage, the right amount of soil mix, and it’s more obvious how many seeds there are per cell.”
There are also biodegradable options like peat pots, expandable peat or coir pellets, or pots made from composted cow manure. Carrie Spoonemore notes, “You can use individual pots you already have on hand, but many gardeners find it difficult to keep so many larger pots covered under light and warm when the seedlings are small.”
Gathering Your Supplies
In addition to your seed starting containers, you’ll need a few other essential items:
- Seed-starting mix: An organic, soilless mix is best, as regular garden soil is too dense for delicate seedling roots.
- Grow lights: Fluorescent, T5 high-output fluorescent, or LED grow lights are required to provide the 12-16 hours of light per day that seedlings need.
- Heat mat: A heating mat helps speed up germination, especially for warm-weather crops like tomatoes and peppers.
- Spray bottle: For gently misting the soil to keep it evenly moist.
- Watering can with a gentle “rain” nozzle: For watering larger seedlings.
- Plant labels: To keep track of what’s growing where.
How to Start Seeds Indoors in 4 Easy Steps
Alright, let’s get your seeds started! Here’s the step-by-step process:
1. Prepare the Seed-Starting Mix
Fill a large bowl with your seed-starting mix and mix in a little water to evenly moisten the soil. You might want to wear a face mask for this step, as the fine soil can irritate your airways.
2. Fill Your Containers
Place your seed tray or individual containers inside a drip tray, and fill each cell to just below the top with the moistened seed-starting mix.
3. Sow the Seeds
Sow your seeds according to the instructions on the packet. For tiny seeds, just sprinkle a few over the soil. For larger seeds, gently press 1-2 into the mix and cover lightly with more soil. A good rule of thumb is to plant the seed to a depth about twice its thickness.
4. Provide the Right Conditions
Cover the tray and place it under your grow lights, positioned 2-3 inches above the soil. If you’re using a heat mat, place the tray on top of it. Keep the soil surface lightly moist, but not waterlogged, until the seeds germinate.
Once your seedlings have sprouted, remove the cover and continue to monitor the moisture levels, misting or watering as needed. When the first true leaves appear, you can start fertilizing with a diluted liquid fertilizer every two weeks.
Hardening Off and Transplanting
As your seedlings grow strong and develop a few sets of true leaves, it’s time to start the hardening off process. This gradual acclimation to outdoor conditions helps prevent transplant shock when you move your plants to their permanent home.
Start by placing your seedlings outside in a sheltered, shady spot for a few hours a day, gradually increasing their sun exposure over the course of a week. This hardens off the tender foliage and strengthens the stems, roots, and overall plant structure.
Once your seedlings are hardened off, you can transplant them into the garden or larger containers. Remember to plant tomatoes and other vining crops a bit deeper to encourage additional root growth. Water your new transplants well and keep a regular watering schedule, as their small root systems can dry out quickly.
With a little planning and attention, starting seeds indoors can be an incredibly rewarding part of your gardening journey. Not only will you save money and have more control over your growing conditions, but you’ll also experience the pure magic of watching new life emerge from those tiny packages of potential.
So what are you waiting for? It’s time to get those seeds started and set the stage for a bountiful spring harvest. Happy gardening, my friends! And don’t forget to check out Today’s Gardens for more tips and inspiration.
