This hospital that we maintain planted 100 trees that were donated to them in memory of loved ones. Notice the plaques at the base of the trees. The nursery that planted them brought in soil to form the mounds around the trees that had wire grass(quackgrass) seed in it and they became infested. There is clover in the grass in this part of the facility, but until now there was no wiregrass. I had to spray them all and re-mulch them to get them to look presentable. Currently, a lot of the dogwoods are dying because they were planted in direct sun and sandy soil and there is no irrigation.
