Garlic Mustard blooms now fading here on May 11, in Baltimore City, in Mt. Washington, in this wooded neighborhood and in nearby local parks such as Lake Roland. Much less Garlic Mustard than I would have expected. Maybe 10% of what I’d expect. I noticed mid-January when I pulled some over-wintering first-year rosettes near my house (after a mild winter), that each single plant with maybe 5 leaves (each leaf then 2 inches across, very green) had 2 or 3 of those leaves gone. Stem ragged, probably due to deer browse. Seems possible that the deer are so numerous, so hungry here, within City limits, that deer are even eating over-wintering Garlic Mustard leaves on the rosettes. Also....
I also notice here another invasive taking over, Lesser Celendine. Carpets of Lesser Celendine. Unbroken patches in many places, 10- 20-30 feet across. Where Garlic Mustard stalks are growing and competing with the Lesser Celendine, it seems the Celendine is less dense. Some brown ground peaks out. Could the Garlic Mustard’s toxicity discourage the Lesser Celendine? Would I rather see/ have Garlic Mustard in the woods or the Mt. Washington Arboretum?
After a decade of diligently pulling Garlic Mustard, I’m thinking I would be wise to leave it standing, to let it compete with the Lesser Celendine. What do you think? Which is more of a negative? And why?
