Haworthia root cutting. (百合修根)
Today, fortunately, I've found two of my haworthia plants have withered roots. During hot summer, Haworthia have a very high chance to get withered roots. In this case, we have to cut those withered ones properly. So, what is the proper way to cut those roots? It's depends, but the general rules are:
1. Keep those strong white roots. (只保留白色粗壯根)

2. Cut anything until you see the pink heart. (Usually it is pink.) This is because the dead tissue will impede the growth of new roots. (清掉其他東西,直到你看到粉紅色的肉,不砍到肉,你的根很難發,也很難茁壯)

3. Sterilize it.(幫他消毒)
4. Wait it dried and go for rooting.  (等他乾燥發根)
