Growing Herbs in Vermiculite

If the seeds are 3 to 4 years old they could certainly be too old to grow. I have never heard of vermiculite alone being used to grow plants. Usually it is mixed with potting soil or a soiless mix. I don't think vermiculite has enough nutrients to be the sole medium for growing plants.

I "googled" it for you. I will likely take 2-3 weeks for the seeds to germinate. The link below is for basic peppermint, but how different could the mints really be?

Good luck!

Hi Paul,

I have never known just vermiculite. I have mixed my soil using not only vermiculite, but pearlite, canadian spaghnum peat moss and potting soil. I use equal portions of each. That should work. If you are only using vermiculite by itself, I would water it well and put a piece of plastic wrap over the pot. Keep checking it daily to see if any have sprouted. Keep checking the moisture level also.
They still might sprout.
hugs,
Marcia
