For the purposes of this post, I’ve made two key assumptions. You’ll be growing a salad garden, propagating your transplants from seed and using the My Garden Post for your vertical gardening needs. I know there are many gardening enthusiasts in the frost-free states who are setting up their My Garden Post (MGP) for the first time and all are anxious to get started. At risk of offending those who have been gardening for years and know their stuff, I want to make sure you use the best growing mediums for seed propagation and the planters. Today’s post is all about the soil. You’ll need a few quarts of germinating mix and 30 quarts of container mix. Thirty quarts will fill all five planters on My Garden Post. Expect to pay $20 or less for both growing mediums.
About the Soil

The growing medium used in the planters is slightly more coarse and heavier than the germinating mix described above. Most good quality container mixes have these ingredients in common:
If the mycorrhizae, humic acid and worm castings are not already in the germinating mix and growing medium, they can be purchased separately and added to your mixes. A little goes a long way.
