Author Topic: Wood Ash Effect (Read 2662 times)

This year we laid a hedge which was shading our garden area ( part of a field) in the morning. There was a lot of stuff to burn which was heaped up in the centre of the garden and burn't there. The result was a lot of ash and charcoal residue which was ploughed in and rotovated.
As it happens two rows of broad beans now pass through what was the bonfire area.
The interesting thing is that you can see the effect on the growth of the plants. Uniform size along the rows then much bigger on the periphery of the fire returning to normal size again.
Can anybody shed a light on the nutrient effect ?

Hi Welshboy, wood ash contains potassium and smaller amounts of phosphate which explains the difference in plant sizes.

This is good news because I just dumped all the ash from my garden wood burner thingy on the compost heap! What with that and the chicken poo it will be FAB!

It is good I put mine as a mulch around trees as mine has nails in.If you put ash on the compost mix it in well as it goes mouldy and slimey.

Its not a good idea to put your valuable potash in the composter.Spread it where you want it and rake it in

Ni mind eh! You can always have another fire.Hawthorn fire ash was much prized in yester year when the bonfire had gone out ti was shoveled up and sacked up and shared out preferably before it got wet.

Interesting. George.
No doubt we will have a few more fires before the summer is out!
So its best just to use as mulch? Any particular plants that appreciate it??

Hello agen Vair.Most flowers like it although I think there is only one good flower in my mind and thats a cauliflower and its not much wi out a goodly coverin of cheese sauce Things like tomato's like it These expensive sprays (Phostogen and Miracle gro ) are rich in potash Potash is a name which was given to burning of wood in large iron pots and the white residue scraped off and bagged and sold hence the name potash although it should be used sparingly if you mulch with it.Does this help Vair?
