Use for wood ashes #351143
Asked August 08, 2016, 9:51 AM EDT
I have just burnt a pile of branches from trees. I have found information that some plants thrive in alkaline soil. If I incorporate these ashes into the soil where these alkaline loving plants grow but next to them are plants that do not do well in alkaline soil, will the minerals from the wood ash be confined to the area in which I apply it or will it also affect the soil of the other plants?
The results of burning has not only produced ash but also wood particles of totally charred wood approximately a quarter in size. Can these particles be used along with the ashes?

Expert Response
A soil scientist's expertise is needed to provide a thorough answer your specific question. However, you will find excellent information about amending soil with wood ashes at this website:

Although this information was prepared for Oregon residents, the principles also apply to Minnesota soils.
Most garden plants tolerate a range of soil conditions including pH, so if you test the soil occasionally and apply the ashes judiciously, negative effects are unlikely.
However, do not apply wood ashes near blueberries, azaleas and rhododendrons.
Bits of charcoal are acceptable but keep them to a minimum and don't exceed the total ash amount limits mentioned in the bulletin.
