Nature
City gardening: do you like to get your hands in the soil?
Humans were not meant to be so remote from Mother Nature as perhaps many of us are who live in towns and cities. In the UK, councils have started to set-up allotments on spare pieces of land perhaps besides a railway or between roads. Some councils have chosen to allow residents to grow vegetables where formerly municipal flowers were planted.
In London where I live, I have managed to get an allotment allocated to our family. To help children learn where their food comes from, the allotment only allows 20% of your patch to be given over to flowers. The council gardeners encourage you to grow flowers that attract bees such as sun flowers or nasterchiums whose flowers you can eat in a salad.
