I planted two earlier this spring. One doing okay, flowered a little, other turning yellow... I did not water too much. It has rained more than normal here. It is strange that one plant doing okay and one doing bad... help! Kelly
It is likely that the rain has caused it to be overwatered, leading to root rot.
You will have to use a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
Since there is quite a lot of genetic variability in plants, it is not uncommon for one to be immune, or a little better suited to handle certain diseases than another. This would explain why one is having issues and one is not.

I don’t know how much to water it to keep in the sun or not. I think I might have killed it and the leaves have become crisp dry...
It appears to be a type of Cranesbill Geranium, but it is very difficult to tell which one in this condition.

Thank you so much for your reply!!
I looked at the article you referred to, my flowers are much smaller though and growing in bunches of sorts... I don’t know if there are varieties in cranesbill geranium where this is found too...
Thanks so much again!
in sunny windiow. Will the geranium actually re bloom during the winter or just stay green and grow new shoots? Any other tips you can provide would be appreciated! Thanks in advance
I reviewed several sources and none said they would bloom. You are just trying to maintain them till you can get them back outside in the spring and ready to bloom again.

I like to know what can I do to remedy my dry geraniums. I have them planted in different sections of my patio that don't get six hours of full sun. Is this the wrong choice of plant for this area or what can I do to amend the soil?
They look like they need to be divided. They could use some more sun, though. That would, certainly, help out.

I have got a greenhouse and conservatory.
The best information I found is from the state of Iowa, USA. The frost free date there is likely mid to late May so adapt the timing to your location. https://www.extension.iastate.edu/news/2008/jan/072501.htm
We plan to make geraniums dormant. Should we cut off the flowers to start? We know the leaves will fall off.
I would remove the flowers. Once the plant is dormant, they won't look good and you'll end up removing them once winter is over if they haven't fallen. It's better that the plant not put energy into making seed while entering dormancy. You want the roots to be as loaded with nutrients as possible.
I have two potted geraniums that I have heard referred to as anti-mosquito or aromatic geraniums. We live in Minneapolis and have been having some late fall temperatures in the mid to upper twenties, so I have moved the potted plants into the attached garage. Other than giving them needed water, is there anything else I should do to protect them?
You will need to keep these fairly warm. They can start to show stress around 50 degrees or so. They will also need extra light. They do not go dormant, so they will die without proper growing conditions. If you can provide a brightly lit room or window, this will help.
