Do you know why the bottoms of the trees are painted white? There is a little apple orchard near here where they do that too, but I don’t know why.
I just googled it and got these reasons:
– prevent sun scald
– makes it easier to spot (apple) borer infestation
– prevent bark splitting (from cold)
– prevent rabbits, etc., from nibbling bark
But I’ve also read that it’s not necessary for any of the above.
Also people do it:
– to prevent motorists from crashing into trees
– for tradition – They like the look of it
I think in the case of this park, it is a style thing. It helps emphasize the regular pattern of the trees, especially in night lighting.
I often like the look of painted trunks as a nod to (mostly European) tradition.
