Just saying 'Hi' to you all. I am Bart, live in Poland. Regarding my interest in Japanese Gardens it started years ago, I always liked bonsai but never nurse one myself. Been twice in Japan and watched temple gardens instead of 'Pachinko & Slat' ;>
Still not own my piece of land but have balcony and now I am trying to arrange some Japanese style 'ISH' micro garden.
Welcome to the forum, I believe there are some posts on the forum about using the walls for vertical plantings on balconies. Good luck creating your space.
