Orange damage on Coryphantha
Posted: Sun Jun 24, 2018 10:05 am
Morning all!
Could anyone give me some insight into what might me going on here please.
These marks are fairly new on this plant (this growing season) and are uniformly all over the plant.
It's one of two I have that are like this, both Corys, in a collection of about 2000 mixed cacti, none of the others are affected. The other plant has been like this for about 2 years.
Plants are treated regularly with DE and occasionally with systemic if I've found a problem.
I can't see any mites on the plants and as I said nothing else is affected. I have seedlings in the greenhouse too so would have thought those would have shown damage if it were mites etc.
Any ideas would be gratefully received.
