can anyone advise me please. Can I dig into my green house earth ash from my fire once it is cold?
It depends what you burn on your fire ...
Only wood ash, not coal.
I wouldn't put it into the greenhouse earth - don't ask me why as I don't know - but I would just scatter it on beds and borders.
Mine goes in the compost bin.
When we had a wood burner we used wood ash in the compost heap or to spread around fruit bushes and orchard trees. However we only burned logs, never any painted or treated wood or any fire lighters or coke/coal etc. as these would be harmful to the garden.
eek! I use firelighters , but I still stick the ash in the compost bins.
Been watching the ornamental Kitchen Garden DVD while sewing and a lovely old chap uses his ash to sprinkle on potatoes after planting and before covering +up with earth. Says it keeps the slugs off the tubers.
Two opinions about ash containing firelighters
I guess the residues form such a tiny proportion of the overall mix it can't do much harm.
