what are you mulching with? the caryopteris won't like anything that makes it too wet.
If you mulch now on dry soil, unless you get really heavy prolonged rain, it will be absorbed by the mulch and the soil will stay dry.
Plants that disappear in winter can be mulched over but those that have some leaves in winter won't like it.
Plants that like hot dry conditions won't want to be mulch with manure.
this is my theory-of mulch. Others may do it differently
