When you harvest water spinach / morning glory late about 30 days, the bottom of the stem will get hard, so the ideal time is 20 days, so we do need to cut / remove their stem to much. I heard on my country, water spinach is illegal to grow. How's your living country rules for now about growing water spinach?

For the stickers, I use for cucumbers to make cucumbers looks great, dominant to hang on the their stems, to complete my Youtube video visual.

For the mustard greens, the stickers will help the stems not easily be broken when big rain and wind comes :)

For now, I gave my harvest for free for surrounding people here :)
