| Because I find these unsightly, I always remove same with an old toothbrush. Can anyone tell me, do they harm the tree in any way?, for instance they are using this larch as a host, would the larch loose any strength because of this?

| Kath. There was a discussion about lichen on BH. The conclusion was that bits do no harm but when they begin to cover a lot of bark they can prove fatal. I'll try to find the URL. =Don.

My imaginary friend Givitago takes over when I'm not sure of myself in print. He's not a complete fool - several bits are missing.

| Thanks for the link Don, an interesting thread re for and against removing it. I have taken mine off yet again with the ol' toothbrush. The main reason I asked how it effected larches was because it has appeard in masses on my old berberis 'darwinii' hedge around the front garden and has killed it in places, so bit by bit am replacing it with Pyracantha 'sapphire'. Because the berberis hedge is very old and weak I wondered if that was the reason for such a vicious attack of the lichens. At least we have pollution-free air, that's if we believe all that we are told

| Hi As I said on BH larches often are covered with lichen in the wild. It might be different for a small tree as there would be a greater percentage of cover. I have some on my larch bonsai, not much, but I have not removed it.
Best regards

| Hi Kath, following on from that debate, not only have i removed all the lichen from my larch, i have removed it from all my bonsai trees. i found it much easier to remove it when the lichen in wet. Below are some before and after shots.

Thank you for the photos Roy. They certainly look much better, I was just worried that the small branches might suffocate with all that thick lichen clinging on, and especially as that looks as if what has happened to my berberis hedge.
