I have never had a problem in the past with geraniums. In fact I love them because they tolerate dry conditions and bllom like crazy. I have both regular geraniums and huge baskets of ivy geraniums (my favorites).

It's been above 90m degrees for at least 10 days now (plus very humid). They don't seem to have many blooms coming along, even though I fertilize them lightly with every watering.

Has anyone else had a problem with geraniums and extreme heat?

TIA.

Mine are in full sun and they've had their share of heat.  I don't fertilize them and water them once or twice a week.  They are thriving.  Maybe cut back on what you're doing.

@terrier3  I have both types, some in filtered sun and some in direct sun, both are fine, but I think most plants like some relief from the blazing sun.  I don't feed mine, never thought to feed geranums, but they would probably appreciate it.

@terrier3, do these apply?  I am usually careful about fertilizing plants in the high heat, especially if there has been little rain.  Just a thought.  LM

A. The two most common reasons for geraniums not blooming prolifically are too little light or too much fertilizer.
Geraniums are a sun loving plant that need 4-6 hours of full sun a day, or perhaps longer in somewhat filtered light. South and west exposures are usually best. In too little sun, the plant will often grow, but will tend to grow a little bit taller or leggier, as it reaches for the light and it definitely will not bloom as much. The number of flowers is very much related to the amount of sun that the plant gets. As far as fertilizing goes, if geraniums, like most annuals, get too much, you will get large, lush green plants and not as many blooms because the plant will be in more of a vegetative mode. In containers, if you feed your geraniums, every 3 to 5 weeks, you will be just fine. Use any of the water soluble fertilizers available, and just get a balanced solution (10-10-10 or 20-20-20). In the ground, your geraniums will need to be fed even less frequently; every 4 to 6 weeks should be sufficient. If you are going to make a mistake fertilizing, you are much better off to under feed than over feed.

Thanks for the advice, everyone!

In TX its hot from April till October. I have many ivy geraniums that I've had for years. Every spring I put three Jobes fertilizer spikes for flowering plants in every pot. They are full of blooms until August, they slow down, then once it cools off they start blooming again. Last winter was very mild, every plant was covered with blooms all winter long.

Geraniums are an annual for me.  I put Osmocote in the soil when I plant them and then just water.

My geraniums are filled with blooms but in the last 3 weeks the leaves have started to fade.  Lots of blooms but it looks like the sun has drained the color from the folage.

The tomato's suddenly croaked too.
