How to Start Seeds Successfully Indoors

Show Notes
If you aren’t starting seeds, you’re limited to whatever you can plant directly into the garden and whatever starts you can pick up from your local garden center. Starting your own seeds opens up possibilities for growing new crops you couldn’t grow otherwise, better varieties for your garden and tastes, and earlier and better harvests to make it all worth it. In this episode of Granite State Gardening, UNH Extension’s Emma Erler and Nate Bernitz share proven tips and solutions for successfully starting your seeds indoors, from set up and germination to transplanting. Come for the accessible science, stay for the demystifying banter. Once you learn how to start seeds indoors, you can take your gardening to the next level.

Greetings Granite State gardeners I'm Nate Bernitz, co host with Emma Erler of the Granite State gardening podcast, a production of UNH extension. Today we're talking about seed starting a practice that opens so many possibilities for gardeners, especially somewhere with a relatively short growing season like New Hampshire. By starting seeds. You won't rely on just whatever seedlings you can get your hands on from local garden centers and plant sales. And you won't be limited to what can be so directly in the garden. You'll have your choice of crops, flowers, and varieties galore to choose from all because you'll be able to provide ideal germination conditions indoors. Once you learn the science and know how of seed starting, you'll be at a whole other level of gardening and won't believe how limited you once were, with spring rapidly and mercifully approaching despite what Punxsutawney Phil says there's no time to waste. So let's get started. Emma, when it comes to seed starting, I want to first know the science, we always want to know the science first. So what are those ideal conditions for germinating seeds?

Well, a seed is is basically a shell or husk that's holding an an embryo on the inside. And in order for a seed to germinate, you need to have some specific conditions, you need to have moisture in you need to have light, and you need to have oxygen. And if you don't have those things, then the seeds not going to germinate. When we're talking about germinating seeds at home, we are providing that at least the moisture, at least moisture and oxygen in our seed starting mix that we're using. So that's that potting media that we've chosen to start our seeds in. And then light that's either going to be coming from a really bright window, or ideally actually from some sort of some sort of supplemental lighting system that you have inside your home.

Okay, so moisture, oxygen and light, not nutrients because these seeds already have the nutrients they need to at least get started, so to speak. So ideally, we're recreating these really ideal germination conditions indoors. We know the science, it's been researched, it's been determined, this is w...
