As Ella Mills and Ava Siemering of George Washington Carver High School shared an interest in horticulture, they knew they wanted to grow plants as part of their Caring for Our Watersheds project.
After doing some research, they learned about vertical gardens and how they can allow people to utilize the space available in urban environments more efficiently and economically. In addition, they can help improve air quality in congested areas, as well as provide food, aesthetic value, and energy savings. They decided that they wanted to experiment with different designs for these gardens using recycled, or reclaimed materials and create one as a demonstration for their garden class at school.
This process led them to create a small vertical garden which demonstrated how to place plants with higher water requirements on top and plants that need less water below. The lower plants can survive on what drips out of the holes from the ones watered on top. They presented their hands-on experiment in water conservation and horticulture to the students in the garden club and talked about the benefits of vertical gardening.
