Q.White Stuff In Garden Soil/raised Garden

Zone Zone 7 | Robinspear added on March 3, 2024 | Answered

For the last two years, one section of my raised garden has troubles with white mold, mites or something growing on my herbs. While cleaning the beds today, I noticed white growth on the timber. Can anyone identify problem? Do I need to remove all soil and start over?

Unfortunately, fungi such as this one, are very difficult to identify without a microscope. What we can say for certain is that the fungus prefers woody, lignin rich substrate. Depending on what species, it can sometimes try and eat your plants.

The best way to get rid of the issue is to treat with fungicides. Removing soil will not ensure that it has not crept outside of the area. It will infect the new soil, as well.
