Linda, you are worrying too much
prune in March or thereabouts when new shoots are forming to remove dead stems. prune off any stems not producing new shoots.
is your plant in a pot? if so you will need to water it well and regularly.
A good thick mulch in autumn will help your plant cope during hot dry weather
this is one of mine, about 10 years old, pruned every spring
