Hi need your help both Clivia have flowered and have been in the shady side of the garden all summer. I bought them in to repot and noticed all rust type marks on underside of leaves. This is only on one plant. Any idea what’s caused this ? How can I treat it. Thanks

I think it is probably slug/snail damage. It doesn't look like the disease rust. Keep it away from the other one just in case and see if the damage produces a rust brown powder. if it does then that is rust disease. Not sure if a fungicide would work on it but wait and see.
