about 6 months ago we mulched a huge cyprus theodora tree. its been composting and when i turn it over it has a load of white fungi in it could i use it as a path in my polytunnel or is it still too fresh and  could it csomehow damage the soil(besides taking nitrogen from it)

I think i'm right in saying that it will have a high acid reading.

i have a huge bag of builders lime and my soil is naturally limey. what do you think the chippings to lime ratio should be? getting a bit complicated now sorry

[Pompey Spud]

Don't know and yes...too complicated.

But after reading your post again..fine to use as chippings for a path over some fabric.

If using only as a path then no need to lime.

If you end up wanting to cultivate the area under the chippings then I'd let them rot down for a couple of years or more, dig into the soil, allow to consolidate, measure pH, and at that point adjust the pH to what you want it to be. Faffing around with lime now strikes me as though you're just going to be making work for yourself.
