My Geraniums leaves have got white splashs on them looks like someone had flicked paint over them. I have checked the leaves under side as well cant see any bugs and no damage to the leaves.
Have they been outside? It could just be birds.
Or have you watered them when it was sunny? Any water droplets on the leaves could cause marking.
Hi Alina yes they are outside it maybe water droplets as last week we had rain then strong sunshine right after it i will keep watching thanks.
Could they have been frosted? It's still a little early to put them out, if they are pelargoniums.
