There are a few things that I have learned in gardening and the one major lesson is that not all soil is created equal and that the more you put into improving your soil the better off you will be all the way around. I'm going to tell you that this is going to probably be the most expensive part of gardening, it certainly was for me, however you will reep the rewards in by vegetables that are big and beautiful, without all the added checmicles and fertilizers needed for poor soil.
I chose to use the raised bed gardening method because of the sandy nutrient poor Florida soil. For me it made more sense to start with new soil Right from the very beginning instead of giving myself a migraine with amending the soil and then just ripping it out in the end anyway as I've been known to do. To fight the rocks shale and attempting to amend what I already had.
I have read the book "All New Square Foot Gardening" by Mel Bartholomew, and have taken his suggestions for his soil "recipe" and made some adjustments and additions of my own, based upon local availablity of some of the components required for the compost, along wtih the addition of the two types of peat moss. I would recommend anyone getting into vegetable gardening to read this book, it's a must have and offers so many insightful tips and information.
Here is a list of the componets of the soil in my raised beds. I had some local purchases, and some I had to drive to Arcadia, FL to get. If you find any of these closer, or cheaper, please feel free to leave me a message or post. I would LOVE to share and collaborate on any ideas you may have.
Math 101 to calculate how much soil you will need:
Multiply the widths of your box, and divide it by 2 to figure out how much volume your 6" deep box will hold:
(4 X 4) / 2 = 8 cubic feet
(4 X 8) / 2 = 16 cubic feet
(4 X 12) / 2 = 24 cubic feet
(4 X 16) / 2 = 32 cubic feet
Do not go by weight!!!!
