"Square foot gardening uses a smaller area to produce more plants, crops, and flowers. If you wish to grow a large number of crops, square foot gardening is the way to go." Tom Ford does a very good job in covering the basics of square foot gardening. In this short book he discusses the history, benefits, advantages and disadvantages to this method of gardening. He covers the layout, location, climate warnings to consider before planting or harvesting.
Although I agree with the book overall, I found him to be very vague about measurements or use of additives. For instance, "You need to water your square foot garden every day so that it isn't affected by the weather conditions in the summer." Most plants do not need to be watered every day in the summer, especially if they have a thick covering of mulch about two or three inches to protect the roots. Nor does he cover how much water to use every day; this is important because overwatering will kill the plants.
He gives sound advice about testing the soil to see if it is acidic or alkaline, but then gives vague direction regarding adding vinegar or baking soda. "For example, if you would like to grow crops that prefer acidic soils, you can add some vinegar to your soil to lower the pH value of the soil. On the other hand, some plants thrive in soils that are more alkaline. If you would like to increase the pH value of the soil you can use baking soda." How much vinegar or baking soda is needed to do this? He never explains.
I also found some erroneous advice regarding seeds: "Seeds- if you are growing plants from scratch you would need seeds to sow them. Be sure to dig them deep into the soil because birds tend to pick the seeds from the soil." Correction some seeds can't be buried deep, in fact, certain seeds barely get covered in soil to grow. It is important to follow the directions found on the seed package itself which will tell the gardener the appropriate depth.
This book was basic in teaching the concept of square foot gardening. I would definitely recommend this to a beginner who is interested in gardening.
