Q: What common plants in the MD area like wood ashes from my fireplace - pachysandra?
You first need to have your soil tested to see the potassium level and the pH. Soil varies from garden to garden so there is no hard and fast rule. Ashes will raise the pH. Wood ashes were used before fertilizers were available. You can add them to your compost pile but don't overdo. I suggest you Google using wood ashes for more information.
