What’s Chimney Soot good for?
‘Did you know, chimney soot is actually a great nutrient for your garden as it is high in nitrates’?
Chimney Soot is high in Potash, a major nutrient that is essential for good fruiting and flowering and it also helps the plants get through the winter. It can also be a useful additive to the compost heap or can be applied directly to fallow ground and dug in. It also has a liming effect, so wood ash can remedy excessively acidic soils.
Chimney Soot is not the same as ash, soot is more like charcoal – pure carbon with some volatile compounds. That’s why it’s good to let the soot weather before using it – the volatile compounds evaporate and what’s left is like fine charcoal.
