Why do my cone flowers seem to only flower every other year? They are planted on the southside of our brick house. My Bee Balms seems to do the same thing? Do I need to replant more of each?

Echinacea and monarda bloom every year here....
Matter of fact, echinacea bloom repeatedly all growing season for me.

Wonder whether moving some of them to the other sides of the house would have any effect.

Did you save any seed?
Echinacea comes up easily from cold stratified seed... Most monarda spreads aggressively from the roots, should be plenty to divide.

Odd these are 2 of the more reliable plants to flower every year, and like stone said Echinacea flower repeatedly over the season. Do they need dividing? Echinacea do not like much food , overfeeding can cause larger plants with low flowering.

I might get 1 or 2 plants to come up and bloom but then the next season they are abundant? Do you think it has to do with rain or not much rain? We are on well so I cannot afford to water daily or even twice a week when it is very dry. Could this be the problem with both? Our soil is very hard as well.

At my house in the arid Sandhills, these bloom without supplemental water.

So... I don't think watering would help.
Digging the beds and adding organic amendments might.

I picked these plants due to them being drought resistant so I am happy to hear that info.
Maybe they are just tired? I planted them all some 10 maybe more years back.
Thank You for your advice on this matter.

I do not think water is a factor with your Monarda and Echinacea blooming every other year. They thrive in drought conditions.

You may want to check the pH of the soil in this area, most cone flowers prefer a neutral soil pH of about 6.5 to 7.0.

Do you mulch your plants? A mulch of compost in the spring might give the plants micro-nutrients that could give them an extra push into bloom???

You certainly don't want to water too much. An unusually spring caused some exotic hybrid echinaceas to bloom and then die of some fungal disease. The common echinacea plants finished the season strong and healthy as usual. Several friends had similar problems.

Thank You for all the helpful tips.
