I often walk past a small front garden that contains three pot plants. I’m not sure what they are but they’ve been there a few years now. The plants outgrew their pots a long time ago, they desperately need repotting. In the summer they are dry and never seem to get watered by anyone. In the autumn they are full of water that doesn’t drain away, in fact I passed by them today and they were filled to the brim with rain water. In winter, when the temperature drops, they sit in frozen water-logged earth.
