As you know when I went to a session that was container gardening. I found that this may the best option for me. Since I work with students that have disabilities, I can use container gardening to differentiate instruction.
To the left is a picture of aplastic container with rocks and pipes with holes in it. You would then add the dirt. The pipe would allow the water to reach the bottom of the plant. gutter. They did mention that the best plants for this container would be plants such as corn, broccoli and fruit trees. As a side not, I will be getting the containers that roll too help me move them as needed.
