Red leaves on geranium

Question

I have a geranium which leaves are turning red and yellow. I know that means it’s under stress but I don’t know what’s causing it. I don’t water it often but our area is not very dry. Any ideas what is the best thing to do for it?

Answer 1

It's summer here in NZ so that's not the problem

Answer 2

Cool temperatures are the most common reason for red leaves.
