用大花盆 中間種豆 或 秋葵 或 玉米 or flower then surrounding plant vegi.
小白菜 清江菜 油菜 芥蘭菜 只在winter 種 otherwise you will get a lot of bugs. 空心菜, 地瓜葉, 韭菜(when harvest just cut the plant a little bit above the ground 1mm), green onion and leek (just slid the garlic into the soil.) When you wash the vegi, fish and meat all those water pour into the plants then you will get enough feterlise. Of course milk waste and fruits skin will do good too.
