The bottle gardens from last spring have mostly all been given away but I still have one. I thought I would update the info. This one I put in moss and peat moss both. The moss alone dried out too quickly alone but the peat moss added makes it work rather well. Out of curiosity I used house plants instead of the normal use of quick veggies.
The plants I tucked in the window-garden were the ones broke off by the cat. Now in the south window in their new home they seem quite happy. I use V-F 11 one a week in a mist to fertilise the plants as the moss itself doesn’t offer much.
