By now, if you’ve started some seeds inside, your seedlings have popped up and are growing every day. It won’t be long until you’ll need to provide them with some extra nutrients to stay healthy and thriving.
If you used a commercial
seed-starting mix to start your seeds, that soil-less mix creates ideal germinating
and growing conditions for seedlings by keeping them moist and preventing the
soil from compacting. However, those mixes generally contain no nutrients. They
don’t need to. Each seed contains all the nutrients it needs to
germinate, grow, and produce its first set of leaves.
When the tiny plant sprouts its second set of leaves — called “true leaves” — then it’s time to start providing some nutrients.
Treat them tenderly
Your seedlings are tender, so you don’t want to feed them with a full-strength fertilizer, which will burn their tiny roots. Instead, dilute a liquid, water-soluble fertilizer to half strength and water with that once a week to give them the nutrients they need to continue to grow. Continue this for a month or so, and then feed them every 10 days or so with fertilizer at regular strength.
Each spring finds me in my greenhouse, planting
the seeds that eventually will fill my garden and produce the varieties of
tomatoes, peppers, corn, squash and more that I like the most. For some,
researching and ordering specific seeds, making a batch of seed-starting soil,
planting, and raising seedlings is a bit labor-intensive, particularly when
they could buy plant and easily stick them in the ground.
I get that.
But there’s much to be said for starting your own seeds. Here’s why I do:
Tending the seed
First, it’s a huge sense of accomplishment — to
me, anyway — to nurture a plant from its tiny seed all the way through harvest.
From planting, watering, setting on heat mats, fussing with lighting, transplanting,
hardening off, and finally placing in the ground, each and every plant has been
lovingly grown and tended from the very beginning.
I learned a long time ago from a greenhouse grower that healthy roots are the foundation of a healthy plant, and by raising them yourself, from seed, you’ll know that each plant is strong and healthy.
Discovering new varieties
Second, I prefer the diversity offered by growing from seed. Yes, shopping commercial greenhouses is a joy, with the explosion of colors and all the plants and possibilities; however, they generally tend to carry a very limited variety of flowers and vegetables. And you see the same ones year after year.
How would I ever know that the Riesentraube is one of the most prolific, and flavorsome, variety of cherry tomato? Or that the Corno di Toro Giallo Italian pepper is sweet and spicy? Each new variety is like an exciting discovery.
Customize your garden
Third, you can grow exactly the kind of garden you want. A monochromatic flower garden filled with nothing but white bellflowers, ranunculus, gladiolas, polar bear zinnias, candy tuft, dahlias, vinca, and begonia is breathtaking. Same with blue, using indigo-colored flowers such as columbine, flax, lupine, cornflower, bluebells, allium, and delphinium. The seeds for all these are easy to find.
My gardens contain primarily heirloom plants, because I’m partial to the old varieties and the history behind them. Heirloom plants are not easy to find at most garden shops, so starting seeds is usually my only option.
Finally, growing seeds is much more economical than buying plants. With
just a few packs of seeds, you can start enough plants to fill up a good-sized
garden plot. Filling that same-sized garden plot with purchased plants is costly.
And if you’re lucky enough to
find heirloom plants for sale, expect to pay more than you do for the more common
Besides, I have a very hard time paying what I think is too much for a plant I could easily grow myself.
