In Minnesota, seed starting can begin as early as mid-February and continue to mid-April depending on WHAT you're starting. A really great guide on when to start which seeds comes from the UofMN Extension.
For those of you new to seed starting here are the basic items to get you going:
- Sterile containers: peat pots or those peat pellets are my favorite
- Some type of tray (most options come with a tray of some sort) The idea is to keep the seed containers off direct contact with the heat mat.
- Soil-less seed starting mix (I recommend Dr. Earth, Espoma or BlackGold)
- Light - florescent or LED
- Heat mat - check various sizes
- Fan
- Your favorite seeds
- Vermiculite to cover the seeds when first planted
- Labels
Starting with sterile containers means the odds of bringing some disease to your seed before it even has a chance is significantly reduced.
A soil-less seed starting mix is the best planting media as it's light & fluffy consistency allows those seeds to "wake up & stretch".
Plant your seeds according to the directions on the packet. For small seeds, add a light layer of vermiculite to help retain moisture. (View Audra's first segment on seed starting on Gertens website)
Supplemental light is a game changer. Hang the lights from chains so you can raise them as the seedlings grow. The light should be no more than 4 inches above the top of your plants and even as close as 2 inches. (read the back of your seed packet) Seedlings need 12 to 16 hours of light each day. Natural daylight in winter is not enough. Don't leave it on ALL the time, plants need a dark period too. Amen, we all need some rest!
An easy set-up for small spaces
The heat mat has a dual purpose. It allows for faster germination and, with the heat coming from underneath, helps prevent Damping Off, a fearsome fungus that will kill those sprouts.
The fan is for later when your seeds have become seedlings. A fan lightly blowing across the seedlings for about an hour a day will help strengthen their stems and prepare them for the outdoor elements. Or as Audra says, "rough them up a little".
Plant the seeds, experience the sprouts!
Now for the seeds. Honestly, this is the most difficult part as there are SO many choices. I've been known to stand in the seed packet aisle for, well, let's just say I've been asked to move along. ;-) THE most important thing to remember is to READ the label. I'm serious, there is a wealth of information on the back of those packets to help you succeed.
