1. Engage children from local Boys and Girls club, or other clubs that focus on the next generation to beautify an area they live or go to school in.
2. Planting food plants in such area is not practical, growing pickable flowers can cause other issues. So what can be a good suitable use of that small plot of soil? (Social Studies). Make one block a high school project on learning the history of the area (going back at least 100 years), test the soil for what it needs and what dangerous chemicals might also be presented (Science), Calculate cost of sharing, geography for plants, and for you math wiz out there, apply algebra and other advance math to this. Etc. Etc.
3. Get some seniors out of the homes and into the communities again. Have some speak of what used to grow naturally along these areas, maybe they can take trips to the local garden center or botanical area with volunteers to make some choices.
4. Dealing with the inevitable ripped out, poisoned, pee-ed on, destruction of hard work. Instead of seeing it as a total defeat, work with the group to use it as a social barometer of what could be wrong in the area that needs engaging? Is it one person on a bent of destruction? Does this person need some social services or are they undeserved? It is the behavior of a group of bored teens? What social justice can be done to help that issue?
Basically the small little plot can be a jumping off issue as well as a ‘therometor’ for what else can be going on that needs to be addressed.
