    Much as I am putting the job off, I am going to have to hack my fallen buddleia tree up at some point soon, and the best means for disposal for me is going to be to burn it. Thing is, I will need to burn it straight away which means that it will still be 'green' if you know what I mean. Will it burn fully (if a little smoky)?

    I will be burning it in a burner (when I get one), with the intention of using the ash once cold to spread on the borders - should I dig it in really deep or just dig it through as I go planting stuff as the year goes on?

    If you burn it with other stuff it'll go, don't think it'll burn on its own though.

    Sprinkle the ash as and where needed, it'll soak in :)

      I've got some ash to spread after burning some conifers last week. My understanding is that don't use it on acid plants and it's fine to just rake it in the top soil.

          Plan is to get a fire going with paper/card and some firelighters, get the smaller twigs going, and then hopefully the heat of the fire will dry the rest out as it burns? Either that, or I might cut it up into logs to dry for a while - I'd rather not have to store it though.

          There is calcium present in it, which is alkaline, so using it a lot might cause a problem, but I'd expect if its very occassional, the amount involved will barely dent the pH.

            Or, if you use coal to get the fire moving, the resulting ash will be slightly acid, by virtue of the sulphur in the coal.

            When I was a kid, in my grandad's back yard was the 'ash mountain'. Every time he cleaned out his coal fire, he put the ash on this ever growing pile. At its peak it was quite sizeable, and in it grew a well established hydrangea and a very productive red currant bush:)

            Veg always seems to grow well in the spot where you have had a bonfire.
            I'm not sure about the alkaline effect, I dont think its enough to bother most things, plus just how big was this Buddleia? Are you likely to get much ash from it really?

            I usually get a good fire going with off cuts from work if I want to burn green wood, its not easy to get going in these damp times.
            If you could get a couple of old pallets to get it started it might help.

              It was about 15 to 18 foot tall at a guess

                  I always thought that the ashes from coal are a no-no for the garden? I can pick sea coal from my beach all day but haven't as everything from my stove goes on the compost heap. What do you guys suggest?

                  Coal could contain traces of metals, so the industry says not to use them on gardens, but that is mainly to cover their own backs.

                  Plants need certain metals in trace amounts anyway, so unless you're emptying the contents of a blast furnace, a small amount shouldn't make much difference.

                    When I had a charcoal BBQ, I would spread the ash on my garden . Didn't seem to do any harm , maybe it didn't do any good though :scratch:
                    Wasn't coal soot used on gardens , in times gone by ?
