芦荟要如何修剪？
Aloe vera does not require pruning in the general sense; you need only remove spent flower stalks or dead leaves. Leaves that have turned orange or brown should be trimmed to deliver more nutrients to green plant parts, keeping the plant healthy. Smaller and medium-sized plants can be pruned with a knife, while larger plants require pruning shears. Remove any spent flower stalks or plant material, as well as parts of leaves that have changed their color or started drying.
