As promised, a picture of a bathtub garden actually growing stuff.
This one contains a yacon, also known as a peruvian ground apple, sweet fruit root or jicama (but not to be confused with the yam bean jicama-these foreign crops get so confusing!) Also, it contains five garlics, two Darwin lettuces and a pak choi. All are growing well with complete ignorance from me-thinking of that, i’ll give it a dose of worm wee tomorrow.
The watering pipes are also proving to be excellent habitat for frogs, we have tree frogs living in each one. We’ve also discovered another bonus-the winter sun on the metal in the early morning ensures the soil is always significantly warmer than the ground. Currently they’re growing much better than the ground beds, probably also related to the fact that our backyard is somewhat boggy and the wetter than usual autumn means it’s just not drying out.
