hi good morning can I pwood ash from my wood burner on my garden

Provided that you burn wood only, not supplimenting it with coal, then it is OK to put in on the garden in LIMITED quantity. Just a one of sprinkle over the bed is all that is needed. We have a multi-fuel stove that just burns wood most of the time. I save some of the wood ash as a potash element for my potting composts and already have a sack full of it in the shed. Further wood ash production will go in the bin.

I dress my fruit bushes with it in February in moderation. (except raspberries)

Don't sprinkle it around acid-lovers though, if you've got camellias, rhododendrons etc they would not thank you for it (she says after doing it herself).
I've read that it's a good addition to a compost heap.

Never thought of that Teadrinker - will try it.
