Comparing white cedars with white cedars in Edwards Park

This white cedar (melia azedarach) avenue in Edwards Park is growing strongly through being fed by stormwater run-off from the recent surfacing of Lagoon Lane.
You can see the swale at left, between the fence and the trees, through which the stormwater is drained.
The other melia avenue in the park, planted at the same time, which just relies on whatever rain falls on the surface, is growing less vigorously.
