Default Troubled Rose Bush

I've been in the same house for 2 years now. I have 6 rose bushes in the
same area. Five of them are great. One of them, a red bush, continually has
thinner branches, and leaves that turn yellow/droop more than the other 5.

I'm in Southern California, the plants get great sun.
Each year I've pruned the bush down and it comes back up the same. The tree
has probably been in the ground for years. When pruned down it looks just as
healthy as my other rose bushes. I don't give my bushes anything other than
water, I have good soil and get great roses on all bushes but this one.

Is there any chemical I can treat it with that might fix any disease it has?
Or would best to replace it since it's that time of year?

Keep in mind that different kinds of roses grow differently, in
appearance and vigor. The thinner branches isn't a big concern really,
because that just might be the growth habit. The "turn yellow/droop"
syndrome is more worrisome. Have you considered that you might be
pruning too low? Most of us tend to prune a little higher than the
usual 6 -12 inches normally recommended in books and web sites. Try
being a little less aggressive and it might help.

It sounds to me that you might have a nitrogen deficiency but don't go
overboard trying to ramp up the nitro.

Try this. In a month or so, when it starts getting going again (after
your last possible frost), take some compost and add to the base of
the plant. Don't mound it up too much because you don't want the root
graft (if it's a grafted rose) to develop rot or fungus (which is a
possibility). Make a ring around the plant almost like a doughnut.
Then, take the following ingredients, sprinkle them liberally, and
work them into the compost - a handful of epson salts, a couple of
handfuls of alfalfa meal, a recommended amount of blood meal *and*
blood meal (look on the boxes), and some garden granular time release
fertilizer of your choice - many use Osmocote, but there is some
concern about its effacy in 90 degree plus heat (I've never worried
about it myself). With the Osmocote, make sure that you sprinkle it at
the recommended rate - there is a photograph of the proper amount
laying on the soil on the side of the package. Then water the plant
well with water and fish emulsion. Continue to water with fish
emulsion every couple of weeks or, if you feel like it, cut the
concentration in half and water with it every time. If you'd like, you
can use a weak Miracle-Gro solution every couple of weeks as well (or
you can use one of the water soluble dedicated rose fertilizers). When
you use the Miracle-Gro, spray the leaves as well, but only do this in
the early morning because you don't want to burn the leaves from the
hot sun. After about 3 months or so, reapply Osmocote. In your
climate, you'll probably also be able to fertilize one more time in
late summer/early fall. However, I wouldn't keep feeding the bush into
October and later, because you'd like to try and get it to rest (which
may be hard in your climate - others in your region can advise you -
we have a few So Cal gardeners here).

Try this fairly simple plan and see if it works. You should also check
the pH of your soil before you start. You might have a soil anomaly
that isn't present in nearby bushes. Your pH should be slightly
acidic. You'll hear anything from 6.0 - 6.8. If it's in that range,
you should be OK.

Hope all of this helps...

It could easily be a variety that simply doesn't perform well in your
climate. If you spot a potential replacement bush that you just
can't resist, consider it a prime opportunity to upgrade.
