Geraniums Leaves Are Yellowing
Why do my geraniums always seem to turn yellow? Year after year they start out big and bushy and then over time get leggy with few flowers. How do I keep it looking bushy with blooms in the heat and humidity in FL in August?

Most likely it is overwatering. Geraniums like to by dry. Water only when the soil is dry to the touch.
Give it some bone meal to balance the phosphorous back out and that should help bring the blooms back. Cut off about 1/3 to 1/2 of the woody stems on the plant to help get rid of the legginess and encourage new, green growth.
