Over the past couple of weeks I have been talking to people who question whether a 3 by 3 space can yield them meaningful garden produce.
It is not the square area that you plant in, it is the quality of the soil medium that is used. Big gardens can become overwhelming. You might want to start off with something that is manageable and then expand it. First of all make it enjoyable.
The pictures are of one 3 by 3 Square Foot Garden. Tomatoes, kale, cucumbers and string beans all in one.
