Hello -- we have two quite old apple trees that have quite a lot of moss or fungus on them. It is greenish grey in color, and on most of the branches.

Wondered if there is a way to get rid of it with something that is non-toxic to people, birds, other wildlife, the tree, and other plants.

One tree is a Bramley, the other a red eating apple (don't know variety, but when we have more this year, will post a picture to see if anyone knows).

We planted two more eating apple trees, two plums, a pear, and a cherry, too -- we hope the moss doesn't transfer to them!

Thanks for your help.

hi barbj
sounds like moss or litchen i wouldn't worry about it too much ,moss is due to our wonderfull wet climate and litchen will only grow in pure clean air . only if there wasa huge amount would i bother to clear it , you can get a winter wash to spray on it in the winter obviously, that would clear it up but not very organic ! scrubbing brush mabey ?

[michael brenock]

mountainy man is right. the moss and lichen indicates that the air is clear and the rain brings nothing injurious with it like acid rain. Moss and lichens harbour pests such as aphids and red spider but these do minimal damage and the moss does very little harm. Appearance isn't everything but if you want a cure then tar oil winter wash is the solution sprayed on December /January.

Thanks for the information -- We'll put that on the list for winter then. Barbara

Many gardeners are grateful to moss and find it beautiful,---sort of 'established' looking. And it really is an indication of a pollution free environment; guess that's why i especially love it and the look of it.

I agree with Lady Power, barbj, there is something wonderful about lichens...they convey a certain timelessness to anything they choose to cover. And above all they confirm you are breathing clean air.
You may grow to love them when you know they don't harm the trees.
