Briquette ashes for fertiliser

TheSegal

Is the ash produced by Briquettes (Bord Na Mona specifically) suitable for fertiliser? I cannot find much information online and want to be sure before I use it in conjunction with ashes from timber that I burn.

yes, you can use the ash from briquettes in the garden. be careful not to spread them too thickly, they can get claggy in the rain.
ash from wood is OK too, but not from coal.

Excellent source of potash (clue in the name, lol) - the Potassium (K) of NPK fertilisers

I spread wood ashes around my raspberries and fruit trees. Barbecue charcoal is also wood ash.

The peat ash goes slimy when wet: in the country I spread it in a line along the base of a hedge.

If you have a small garden I wouldn't recommend it as it does form a fairly solid pan if not spread out a lot (pan meaning that water will pond on it). If you can spread it thin it would be ok- in my opinion.

btw, i would say peat as a source of ash is great, but as a source of heat it's probably hard to find worse.
