Geranium leaf problem - help needed please

Mine do this all the time. I think it is just the plants shedding old leaves. Just tidy them up and sometimes give them a feed. Baby bio or those little round balls in a jar (Miraclegro?). I cut them back in the winter and store them in the garage. They are just as good next year.

My geraniums are now looking really good again - thank you all

Thanks merlot - have removed all the sickly leaves ( now plants look much better) and will buy the liquid feed recommended in the article

I would remove the sickly leaves and give all the plants in the trough a liquid feed.

They should soon pick up.

They all seem to do it in drought or such. And go in growing although they look very poorly.

Most gerainums are really tough.

Thank you - hope I can solve the problem
