You can use each plant on its own or you can mix them together .
I think on the elderberry it is the leaves you use not the berries.
Another herb used to speed up composting is Borage.
My herbs are growing great at the moment in spite of all of our plant winters. We are currently having blackberry winter and tomorrow morning is supposed to be down in the mid 30's with possible snow showers during the day.
My flower garden is doing good but still needs some spring cleanup. I'm slow doing cleanup because I am training my dog Tessa to guide me around the yard and there has been a bit more traffics than usual and she will not move from her tracks as long as a vehicle is in sight.
Discovered that the honey bees are getting something from the lemon balm leaves. Possibly the lemon oil that makes it smell so good. My husband asked me what they were getting last week. I was confused because I knew they work the flowers but they aren't blooming
