How can I create a sustainable herb garden with limited space?
I'm currently living in a small apartment in Tokyo with a limited balcony space, and I've been dreaming of starting an herb garden. I have experience with bonsai, so I'm accustomed to nurturing plants, but I'm unsure how to optimize the space effectively. I've tried growing basil and mint in small pots, but they seem to struggle due to the heat and limited sunlight. My garden setup consists of a few containers, some vertical planters, and a small railing box. I want to know how I can maximize my yield while ensuring sustainability. Are there specific herbs that thrive better in such conditions? Any tips on soil mix or watering techniques would be greatly appreciated!
