Normal, nothing to be concerned about.

I have brown spots on my hydrangea stems, as in the photo, but the flowers are drying up. What is happening? Can anybody help? Thanks!

Two different things are probably happening, lgkohan.

1. Brown spots in the stems are normal on some hydrangea stems.

2. Flowers drying may be because the plant was recently planted and is not used to the summer. Increase the amt of water this time of the year and give it some extra shade. If you are in the South, the blooms may be getting old. The blooms typically turn colors as they age. Sometimes they turn green, etc but always end brown. Your location, type of hydrangea and, if possible, pictures would greatly help. While at it, please start a new post in case Niki7889 does not like her post being reused by others.

Ck www.hydrangeashydrangeas.com for more info. Get a large cup of coffee ready as the website has a lot of good info. ;0)

I have a question that's not related to this post but I thought I would ask, I have a hydrangea that I planted a few years back, the bulbs were getting really big and starting to loose their color, being brave I tried trimming/cleaning it up but after I did the plant never bloomed again. Will this plant ever bloom again? I read that you can see the bulbs travel through the stem right before the plant blooms but it didn't bloom for the past two years now? Please help.

Ashley, I am not sure what you mean by "bulbs". Hydrangeas don't have any bulbs :-) If you mean the old flowerheads, they do fade and lose or change color over time. Many gardeners choose to leave them in place as even dead, they can be attractive over winter but they can be deadheaded or removed if if you prefer. Just snip them off under the blooms and right above the next set of leaves (assuming we are discussing H. macrophylla). Deadheading will not necessarily generate any new flowering.

As to why the plants have not bloomed since, there could be a number of reasons, including where exactly you live and how cold your winters are, how much you prune and how much and with what you fertilize with.

"I read that you can see the bulbs travel through the stem right before the plant blooms"

I have no idea what this means but it does not happen and makes no sense. Sorry :-)
