Are you referring to taking cuttings? I'm not sure that the picture shows what you are referring to. I think the wrong photo may have been uploaded. I see a spider.
If you are referring to taking cuttings, then you will just want to watch them. They may not need any water until it roots. The soil must be almost completely dry before watering again. Leaving them too moist will cause rot.
