Parks is recommending mulched beds between trees. Mulch provides a more hospitable environment for trees to grow and is easily maintained, prevents damage from mowers to the tree trunks and roots. Additionally, the breakdown of this organic debris will introduce further nutrients into the soil and reduce compaction. If the public has interest, Parks is open to investigating other landscape options to fill in open areas between trees near the middle of the block. However, these options must be low or no cost to maintain.
