As usual, I always optimize all empty space on my home garden, especially for gardening.
Look... this medium pot that used for growing pare vine.
The empty space is used to grow wavy green mustard or 'sawi hijau gelombang'.
I think they will grow so well until the productive period is over.
The growth both of them look so well, although they live on a small container.
No serious competition, really 'live in peace'...
