horsechestnut antifreeze?

took down a horsechestnut lastweek, noticed a blue puddle under the landy, thats strange cos this landy doesn't ever leak.. closer look it was coming from the woodchip, blue staining on water, not oily at all, pieces of stray woodchip on fresh snow were staining the snow blue too, got chipper home and hosed dust off..blue puddle, levels all fine as usual..must be from tree then, lad who climbed tree said afterwards it was on snow on branches up tree too, whats all that then? Ed

We get this all the time, even on ash sawdust leaching out in the rain last week.

I dont know what it is, a combination of the oils on the chains or exudates from the wood. it does seem to be more obvious at this time of year going into sap flow?

Aesculin There's a thread about here somewhere...

Chestnut stain caused by aesculin, of course, why didn't i think of that, thanks Tony, good excuse not to work in the rain..or snow:thumbup1:

Also, when there are a bunch of horse chestnut leaves on the ground in the wet and cars drive over them you get soap bubbles. You can use the leaves as soap... if your really desperate.

I've seen that when the kernals get squished by cars

i have seen the soapy leaf stuff but never the blue stuff, very intertesting thanks for that

It was your climber having a sneeky pee out of the tree whilst you weren't looking, then laughing his head off watching you put your finger in it and smell it, he told me afterwards
