For the purposes of this post, I’ve made two key assumptions. #1, you’ll be growing your garden on a My Garden Post and #2, you’ll be starting your plants from seed. The growing medium (soil) you use is critically important to your success in germinating the seeds and growing the transplants to harvest. I encourage you to visit Gardener’s Supply Company online to source a germinating mix and potting mix that meets the criteria listed in the following paragraphs. The 9 quart bag of Germinating Mix will be all most folks need. The 20 quart bag of Potting Mix just happens to fill all 5 planters on My Garden Post.
Read the labels carefully. Here are the characteristics you want in your germinating mix.
The potting mix used in the planters is slightly coarser and a little heavier than the germinating mix described. Most good quality container mixes have these ingredients in common, insist on them.
The mycorrhizae, humic acid and worm castings can be purchased separately and added to your growing mediums. A little goes a long way.
The GSC soils are my favorites for a few more reasons that I haven’t yet mentioned.
My Garden Post, the vertical gardening system for balconies, decks and patios, and
Gardener’s Supply Company’s potting mix make a great pair for growing vegetables, flowers, herbs and fruit.
