Oh gosh Pam, a week later.....I do hope you have done nothing but what you have described and your plants are indeed safe.......and in the bag.

No pun intended there.....but cutting them back now as you did, did not endanger the plant in any way....as long as they can go now into a cool environment where neither light or water or fluctuating temperatures might cause the plants to re-invigorate themselves before we want them to.

Its always hard at the end of season to decide...."I must take the plants in".....and yet see new growth, new budding and lots of bloom. Geranium is noted for being able to stand up to temperatures below the freezing mark...even as low as 25 degrees fahrenheit. But, why risk frost going to the point that damage could ensue.
So before the 25 is reached, we cut back the bloom, we cut off the buds, and otherwise remove any and all that might pose a problem...such as leggy growth, damaged or weak stems and broken roots.

As long as your plant is not pushed to create new growth at this time, it will survive nicely.

Next February, you will still need to look over the plant for any sign of damaged stems and branches, remova any old leaves and inspect the roots. Then, into new potting soil, watered till drainage is seen, into a bright window and ...its a whole new world out there for your geranium.

Don't forget to turn your plant 1/4 turn every day or so so it receives equal light all round.
