of rain we have had this year? I am pretty sure there is nothing I can do about it now. It was a real shock to look at it last week and see that most of it was brown, not the fall colors.
Oakleaf hydrangeas are drought tolerant and require well draining soil, so if your soil doesn't drain well, the rainy weather could have done it in. Also, oakleaf hydrangeas can develop root rot if exposed to excessive moisture.

In OK, when is the best time to prune an oak leaf hydrangea that has been somewhat disfigured by a bout of black spot?
Oakleaf hydrangeas bloom on old wood, which means the buds formed the season before they bloom. So any pruning should be done in summer after bloom. However, prune out dead or diseased parts as soon as they are noticed. You may have to sacrifice some blooms.

been in the ground about 6 years and been beautiful. now it’s a bit leggy And it’s just filling out from winter but looking leggy and what about all the shoots coming up from the ground. Should I cut them of or leave alone? I started with one bush and now have 2 bushes. Also, Im still confused about pruning. some say leave it alone and others say cut old wood. i’m not sure what is old wood. Love an answer. Thank you.
Don't cut the new shoots - this is how the plant regenerates itself. Remove any older stems smaller than a pencil, but if you remove all the old wood you may not get flowers this year. When a shrub blooms on old wood it just means the flower buds are formed during the previous season. Here's a helpful article:

10 is suitable. However, I saw a local nursery advertising oakleaf hydrangeas so now I wonder if it would survive in my area. Since they were very expensive, I don't want to buy one if it would not do well. Thank you!
Yes, you can grow them in Zone 10. The zone recommendations reflect optimal conditions, but with the proper care you should have success with these. You should have a talk with the garden nursery folks who are selling these in your area. You may need to give your plant a bit of shade and protect it from intense heat.
