Aeonium arboreum problem

Hello,
I've noticed recently some black spots on my aeonium. Small black spots are on bottom leaves like on the photos below. Do you know what it could be? I'll be thankful for advise :smile:

    I know @Hostafan1 grows lots of these ... hopefully he'll see this when he gets in and will be able to offer advice ...

    It could just be sunscreen pigments. How long have you had it and are you careful not to over-water? They shed the lower leaves at a fairly rapid rate as they grow so as long as the top leaves and roots are healthy then this should disappear soon. Clear away any spent leaves just in case it's a fungal issue anyway. That soil looks a bit rough so maybe remove any loose material from the top, add a top-dress of fresh John Innes No2 to cover any bare roots, and then a layer of decorative grit over the top.
    If you can keep your head, while those around you are losing theirs, you may not have grasped the seriousness of the situation.

    The majority of the plant looks very healthy to me. I think it is as @wild edges says, just the lower leaves naturally dying off (excessive harsh sunlight, lack of water/nutrients can hasten this).

    You have a couple of side shoots which are crying out for propagation, which would give you some backup plants. Just cut off the side shoots where they join the main stem. Leave them in a bright but shaded place for 48 hours, and then push them into a pot with gritty, well drained soil. Water very well and don't water again for several weeks. Keep them in a bright place during this time, but not full sunlight.

    They should have developed some roots by this point, and you can gradually introduce them to a more sunny spot. 
  • @wild edges I've cleared all spent leaves and that's how they look like. The black spots are on both sides and I'm not sure if it's a fungal issue or not...




    @KeenOnGreen before propagation should I get rid off the fungus (If it's really a fungal issue)?

    @niemaciek91 I always removed any dead/diseased leaves when I cut off any side shoots for propagation (and that's the case with any plants that I'm propagating).

    As long as you leave the shoots aside for 48 hours or so, so that the end callouses over, and you don't put the new cuttings in direct sunlight for a few weeks, then the success rate is high in my experience.

    Aeoniums often die off, or look dreadful, after Winter (even if kept in a greenhouse/porch), so I find it's good to propagate, so you have some spare plants.
