Experimenting with Potting Soil Mixes
One of the things I love about gardening is being able to experiment. I’m always planting different varieties to see the difference between them. While I was at the feed store a few weeks ago, I spotted their Pro-Mix potting mixes. I’m a big fan of the 512 Mix from Johnny’s Seed and have been using that for quite a long time, but I decided to give Pro-Mix a try.
So I made a flat of soil blocks with each of the three mixes. As far as soil blocks are concerned, the Johnny’s Mix and the Pro-Mix Premium seemed to form better blocks. The regular Pro-Mix has a lot more perlite in it, so the blocks don’t seem to form as well or be as strong.
I seeded three different seeds in each type of potting mix to watch germinate and watering rates.
The seeds are just starting to germinate and so far they’re pretty even across the board. The Johnny’s mix definitely retains water much better than the other two varieties. Pro-Mix Premium is in second place and the Pro-Mix is in last place, it’s drying out much more quickly than the other two.
What experiments are you doing this gardening season?

This is my first year with my green house. It is an 8×12 on the south side of my garage. I’m having lots of fun starting things and transplanting. In theory, I should save a ton of money growing my own.
