To keep Baltimore's trees, kill the ivy

March 06, 2012

Thanks to Timothy Wheeler for his recent article about Baltimore's tree loss, some reasons for it and the importance of canopy within cities ("Study finds Baltimore, other cities losing trees," Feb. 28).

I appreciate city forester Erik Dihle's description of Baltimore's plan for doubling the city's tree canopy by 2037.

What was not mentioned as a threat to the longevity of older trees is English ivy. Like a boa constrictor, it can squeeze the life out of a tree.

Northern Baltimore, where I live, is rampant with it. My hope is that home owners will recognize this threat and cut the life out of the ivy near the base of their trees before the life in their trees is cut short.
