Weeds!

I hate this kind of weeds! They grow very fast and once settled, very difficult to get rid of them. They grow so much in my styrofoam box with the 3 kailan!

Decided to get rid of them in this box once and for all!! My method? Haha... Layering 1 layer of newspaper first throughout:

Then layering a layer of soil on top of the newspaper:

Finally I heavily mulch it with sweet potato leaves (I didn't take a picture for this!). I hope the weeds will die off after a week so that I can grow my long bean green in them! Shall update if this is effective!! LOL
