to do with wood ash?
I put wood ash straight from the fireplace and incinerator on my
garden? What plants would it help?
main nutrient wood ash provides is potassium, which it contains
in relatively low amounts compared to compost and most other fertilisers.
You can use it straight from the fireplace but it generally has
a high pH so spread it sparingly around the garden and avoid using
it near acid-loving plants like rhododendrons (right), gardenias
and kalmias. Spreading it can be tricky, as it's very fine and tends
to blow around in the slightest breeze.
The easiest way of putting
wood ash to good use is in the compost heap - spread a layer of
ash with grass clippings or vege scraps. This way, the alkaline
nature of the ash helps the composting process and, when you turn
the compost heap, it mixes in well.
