Turns out that in this moderate weather at least, it is possible to grow a garden in pots on a small balcony. I'm watering it only with water saved with a bucket in the shower while the water is heating, and saving more than I can use at the moment! So hopefully I won't have to go shopping for lettuce, tomatoes, capsicum or various herbs anymore; and that if they all work out, I'll add more plants to the collection. (By the way, the pots I'm using are either old ones that are in re-use despite looking worse for wear, or new pots that are recyclable.)
I'm trying to leave no trace on the world, by doing little things every day. Maybe you can join me?
