Well now is the season for pups on your aeoniums. And with the pupping season theres also the culling season. Lots off plants having a pupping frenzy!
For aeoniums with pup that have a large difference in size, in this case Arboreum ssp holochrysum, I remove all the smaller and weaker pups.
If the pups are all pretty evenly sized, no treatment is needed, just enjoy them growing!
