Dust on Plants

[aclum]

Our gardeners did a big yard clean-up in our raised bed garden area yesterday. It's been bone dry around here and between ripping up the old, torn landscape fabric, using the weed eater in places, and raking up around the beds they stirred up a huge amount of dirt and dust. All of the plants seem to have a fairly heavy coating of dust now and I'm a bit concerned how this might affect pollination of the flowers and, perhaps more importantly, how it might encourage spider mites. I recall reading that spider mites thrive in hot, dry, and dusty conditions. I'll probably put down new landscape fabric to help with the dust, but in the meantime I'm wondering how I can get rid of the dust on the plants.

Do you all think it would be OK to just spray the dust off with a gentle shower spray from the hose done in somewhat shady but warm conditions? Not sure what else to do, it hasn't really been windy enough here to have that blow off the dust.

Thanks!
