Volunteers and Nine Mile Run staff set out this past Saturday morning to weed and mulch over two dozen trees along the Port Authority’s Busway Linear Park along Edgewood Avenue in Swissvale. Armed with gloves, shovels, and wheelbarrows, the group got right to work improving the tree pits after a brief overview from NMR staff member Jared Manzo.
The weather was chilly and traffic along the road was a bit intimidating but the volunteers were not deterred! Volunteers assiduously removed weeds that compete for soil nutrients, and spread mulch at an even depth making sure to pull a few inches back any mulch from around the trunks of the tree.
By the end of the event, we had tended 24 of the 28 maple trees. NMRWA staff finished the final four trees the following week. Thank you to Veltre’s Pizza in Swissvale and Coffee Tree Roasters in Squirrel Hill for the donated refreshments for volunteers.
NMRWA is extending their effort to benefit these trees by undertaking a tree pit expansion project. One of the greatest challenges for street trees is a lack of adequate soil volume. With Port Authority of Allegheny County’s permission, we are removing a strip of concrete to connect existing tree pits in pairs. Thirteen sites have been identified. Six will be completed in the remainder of 2015 with the other seven completed in 2016. The purpose of the project is to create more area for water infiltration and rooting space. Hopefully, this work will equate to larger, healthier, and longer lived trees.
If you are interested in helping trees in Swissvale, we will be planting trees this coming Saturday, November 14th, 2015 along Columbia Avenue, Delaware Avenue, and the Universal Academy of Pittsburgh. This will be our last tree event of the year so please come out and help us finish strong!
