Guide to Invasive Plants

Ask Extension
Is this fungus/mushroom harmful to our maple?
We recently noticed this fungus/mushroom growing on a large silver maple. I believe it appeared or grew to this size sometime in the past few weeks. Is it harmful to our maple? Should it be removed?

Learn About & Improve Your Soil
Healthy soils grow healthy plants with fewer pest and disease problems. University of Maryland Extension web pages can help you with soil improvement, filling raised beds, and selecting fertilizers. A basic soil test will give you the soil pH, nutrient and organic matter levels, and recommendations for fertilizer and lime, if needed.

If you want to learn more about the soils around your home or in your community check out the new Rutgers University factsheet on using the Web Soil Survey, a free resource from USDA-NRCS (Natural Resources Conservation Services).
On the Maryland Grows Blog
Each week on our blog you will find a new article addressing topics such as pollinator conservation, growing native plants or food, or how to solve plant pest and disease problems.
