Ash

[muddled]

Can I use the ash from my new chimnea on my plants?

It's 90% wood ash but we did bung some BBQ coals in to keep it going...only a few.
Can I call it potash and dress my tomatoes with it?

When you say BBQ coals do you mean briquettes? They must be charcoal right? Can't imagine BBQing over actual coal but worth checking. If it's charcoal it's wood based and therefore I'd expect it's fine. I put my BBQ remnants in the compost

[muddled]

yes, BBQ charcoal

Thanks Chippy

What about ash from soft woods such as scots pine etc...

Is that any good to spread on the garden or tomatoes?

[Scoot]

Does anybody know?

[Marcusp]

Yes mate all wood ash is a good source of potash

[Scoot]

Thanks. I shall use some on my tomatoes. Only problem is, I don't think i'll be having my log burner on again until October as it has warmed up a lot lately. Never mind haha!

Wood ash from young wood such as hedge cuttings and pruning’s would be high in potash, but from older wood there isn’t much in it.
The ash is still good to use because it has a slight liming effect on the soil. So it’s good for things like brassicas, but best to avoid putting it around any acid loving plants.
