Cranesbill plants really are pretty easy to grow. Planting under such hot conditions is pretty hard on plants. I can't really see what is going on in your photo: are there green leaves that have not dried up? Many plants will drop some leaves under harsh conditions. They may be OK after they settle in. I would water well once per week, and let nature takes its course. If they are in full sun, providing some shade during the hottest part of the day could also help.

For the 1st month after planting they were really nice with many flowers then I started noticing many brown and yellow leaves and no more flowers especially on the bottom picture which is my second bed right aside the top bed. They are in 50/50 sun basically about 4-6 hours of direct sun not full sun. Today I trimmed off all the dead brown and yellow leaves and just tried cleaning up the bottom flower bed.

Potting soil is not intended for amending garden soil and it may not be retaining enough soil moisture under these conditions. How often and how long are you watering? I doubt under these conditions once a week is sufficient - I water newly planted plants of all kinds every few days (slowly and deeply) if no serious rain is expected.

I would cut the plants back hard - hardy geraniums can take this easily - keep the soil and rootball properly hydrated and mulch well to reduce moisture evaporation. And depending on exactly what species/hybrid geranium you are growing, it may very well be done blooming for the season.

The cycle you described is very normal George. When mine get to low flower time I do as suggested above and cut them way back. Hair cut style. They will go through another bloom period.

Potting soil is NOT for filling an outdoor bed. Peat based mixes do very very poorly in outside uncontrolled situations. Geraniums tend to prefer a well drained soil (not a mix), peat holds water too long, and then resists water if allowed to dry completely.
