How to Start Seeds Indoors for Beginners

Why buy plants every year when you can easily learn “How to Start Seeds Indoors for Beginners”?!  I just finished up my order form with White Harvest Seeds  for heirloom, non-GMO seeds and I can hardly wait to get planting when they arrive!

You will need:

* A tall sturdy shelf, preferably metal.

* Seed trays (I re-use my trays year after year, until they fall apart) with covers

*Potting soil (I prefer organic)

*Good quality seeds (I buy some but save seeds as well)

*Plastic garden markers or Popsicle sticks

*Permanent marker

seed trays

I like to take my seed starting trays outside and pour the potting soil over the trays, smoothing the soil with my hands.  Make sure if you’re using last years trays, that you wash them well with soap and hot water to kill any lingering bacteria. 

Then take the seed starting trays to your work area.  I brought mine into the kitchen to make my mess!

The most fun part of this process is choosing which seeds to start this year! 

This might be a good time to take a peek at your pantry.  Don’t grow more than you can eat and/or preserve in a year.  So, if in the Spring you still have 50 quarts of green beans left, you probably don’t need to plant many of those this year.

But we won’t be starting green beans seeds inside, that’s not necessary. 

We’ll be starting seeds that have a long growing cycle or that are just too delicate to start outside, plants like tomatoes and peppers.  There are herbs that are too delicate to start outside, chamomile is one that I’m starting inside.

Deciding exactly when to start your seeds indoors is determined by your last frost date, and that can be found here

My last frost date is April 22, but to be honest, I’ve seen it snow many times around that time.  So, I won’t put much of anything out before the week before Mother’s Day.

Whatever date you feel as though it’s safe to plant outside in your area (yes, it’s ok to decide for yourself based on your experiences) then determine the date you want to begin your seedlings indoors by counting backwards.  In other words, when you read the instructions on the back of your tomato seeds, it might say “start indoors 4-6 weeks before last frost date”.  If your last frost date is April 22 like mine is, then you would want to begin your seeds indoors by March 11.

There is no harm in beginning seeds indoors earlier than that, but just understand that your plants may get really big!  I’m totally ok with that.

5 Ways to Avoid Garden Burnout

I love to use this little seed dispenser!  It really helps with those tiny seeds!

Put one or two seeds in each seed pod and then do what the directions instruct.  That might be to press then down 1/4 inch or to leave them on top.  Just be sure to read the pack of your seed packets to have the best chance of germination.

Start as many seeds as you want, keeping within the rows of your seed starting trays

Then you’ll want to label the rows so you can remember what you planted.  I’ve used everything over the years, but I kind of like just using cheap popsicle sticks.  I write the seed name and the date.  Seed starting doesn’t have to cost much!

planting supplies

When seed starting, it’s important to keep your seeds moist, but not wet. 

Having a nice glass spray bottle makes this so much easier!  You’ll want to keep your bottle of water full, so that you can spray your seeds daily.

Your seedlings need a greenhouse effect, which will be accomplished with the plastic lids that come with the trays.  Don’t forget or neglect this step!  They need the cover!

How to Have a Weed-Free Vegetable Garden

Set your seed trays on your shelf and watch them grow! 

I spray my seedlings every morning, don’t let the soil get too dry. 

Spraying water is much better than pouring water, you don’t want to drown the seeds.

Now, let’s address the issue of using grow lights for your seedlings.  To do this, simply go to Lowe’s or Home Depot and buy some shop lights that are the same width as your shelving.  You do not need special bulbs, simple fluorescent will work just fine as grow lights.

You can either hang the grow lights above your seeds trays (best way) or just be super lazy and lay them on top of the shelf above the seeds.  This is why having a metal shelf is so helpful!

seed trays under lights

The optimal way to use lighting for seedlings is to dangle the light just above the plastic cover of the seed tray.  If you are able to do this, wonderful, my father always recommended it and it does keep the plants from getting too tall too fast.

However, having the light lay on the shelf above is fine, I mean, I’m doing it.

Finally, if you really want to get your seeds started faster, you can invest in these seedling heat mats

I have them and I love them.  They trick the seeds into thinking it’s warm outside by heating the soil slightly. 

You will truly see a difference in results with the heat pads and the lights, and I completely recommend them if you don’t have a south-facing window and/or consistent sun to put your plants.  The heat pads will help to germinate the seeds more quickly.
