Why Are The Buds On My Large Outdoor Geranium Suddenly Not Flowering?

My geranium leaves are green and look very healthy. The usual buds came out a month or so ago. However, they come out browning, and most have not flowered. A few did, but not fully. Please suggest a remedy. Thank you.

It looks like some of them have spent petals on the ground. some flowering is a good sign. I don't suspect infection, but I may suspect nutrient deficiency or pH swings.

You can test your soil for both, fortunately:

I suspect that the pH is too low, there is not enough phosphorus and potassium in the soil, or there is too much nitrogen in the soil. These will be your most common issues. It could be a combination of those, as well.

Here is an article that will help you with the, general, care of the flower:
