This task is best done in the Autumn rather than Spring as having done so their trunks up to eye level (at least) will really light up your garden on dismal winter days with an arresting visual flash of brightness, especially if they there is a dark or evergreen backdrop acting as a foil. ##
The job is easily done with a bucket of warm, mildly soapy water and a stiff bristle dustpan brush. and a final rinse of clean water to lose the suds and dirt.
Yes I know it sounds weird or bonkers but you’ll marvel at your handy work on a dark winter’s day! If you remember me for nothing else, I’d love it to be for this spot of garden magic!
Maybe experiment with one tree this year so you can see the difference.
