Here is an update to my garden in a bag. 1 month later the maters are growing very well!

The reason why I did this was 1) it is an experiment and 2) I did not want to dig out and weed a new bed. If you Google “growing tomatoes in bags” you will see both pro and con arguments, but I have to say that so far, even with Florida’s lack of rain, my plants have been doing very well and I water them maybe only every other day. The reason why I went with the Sta-Green product was the $7 / 40lb bag price at Lowes. Although the bags had fertilizer already added (I did not realize that when I bought them so they won’t qualify as “organic”) I have been supplementing with organic water fed fertilizer once a week (powdered Seabird Guano, Maxicrop, Azomite Rock Powder and Superthrive plant vitamins. The first three items I sold to myself from my garden store). I used to have a raised bed garden (see http://www.floridagardener.com/vgarden/raised.htm), but the weeds (torpedo grass!!!) invaded it in the first year, eventually the wood rotted so I just returned that spot back to the lawn.
So far, I have not had any weeds get into my bag experiment, but I am keeping an eye out for hornworms. I made a mix of Thuricide (a natural Bt product) and wet the plants down with it today. We had some rain here in South Florida the last couple of day so they should be happy regarding water until next week!
