I cut it back and trimmed it. Gave it a shot of iron?
I would check for water. Make sure that it is not too wet with no drainage and also check to see if water is penetrating the root ball. Sometimes soil can start to repel water if allowed to be dry too long.
As a precaution, also treat the plant with a fungicide as this could also cause yellowing leaves.
My geraniums are only maturing about 1/4 of the way before they die off. I have planted them in the same planter boxes for years but this year they can't seem to manufacture full blooms. The plants keep producing new blooms, but the same thing happens. . . just a partial flower and then they die. Am I missing something in the soil?
Have you replaced the soil every year? It is wise to replace it every year to help prevent soil burnout and diseases that can remain in the soil. If you have been using the same soil, then likely there is a nutrient deficiency, particularly if you have not been fertilizing. Fertilizer should help.
If you do not see improvement after fertilizing or if you have been fertilizing, it is likely that the soil contains a disease that is affecting the plants. It would be best to discard the soil, wash the container with bleach and start over.
I, m going to pull my geranium up and hang over the winter. Should I prune or cut back before wintering or in the spring?
Yes, pruning them back usually helps reduce shock from bringing it indoors. This article will provide additional information for overwintering these plants: https://www.gardeningknowhow.com/ornamental/flowers/geranium/how-to-save-geraniums-over-the-winter.htm
I have your information on saving geraniums over the winter by making them go dormant. My question is, do you dig up the geraniums while the leaves are still green and flowers pretty before a freeze or after a freeze when the leaves are wilted? I live in Greeley, CO - Zone 5 and we are in mountain time zone.
I want to save my geraniums over the winter with the dormant hanging upside down method in my crawl space. (Michigan winters) My geraniums are huge. They are three foot around and about 18 inches high, first year plants. Do I cut them back now or wait till spring to trim them?
They are generally pruned back by a third prior to bringing them indoors.
I've always felt that hanging a geranium upside down in the basement sounded like "cruel and unusual punishment". I would suggest that if the plant is in the ground, transplant it into a container that barely holds the roots, get it somewhat established, then give it a good pruning. If the plant is already in a container, go ahead with the pruning. Set the plant in a cool place that is sunny, and keep it rather dry through the winter months. We hold our geraniums over this way, and they respond beautifully. Since their root system does not have to revive itself, the plant looks a lot nicer more quickly when spring finally comes.
I have had what I think is a Geranium for a couple of years. It hasn't flowered in at least two. I trim it back every fall and new leaves generally shoot up. This year there are a couple of new leaves, but not much. Is it mean to throw it out and start fresh? I can't help but thinking of it as a living thing.
Are you fertilizing according to package directions? Does it get enough light to bloom? Yes, it is a living thing, but sometimes it's best to end life if there is no hope and you've done everything possible to make it well. (My grandmother used to say, "Hit me a sure lick, don't let me suffer.") Geraniums can be prone to rusts and root damage. All plants have an expected life span. Maybe the time has come. However, if all the needs of the plant aren't being met, try giving it what it wants.

Last year we stored our geraniums in our cellar. What is the best way to bring them back to life this spring?
You should be able to simply plant them back in soil and start watering them. If they survived their dormancy, they will spring back to life after getting some water and sun.
