Our planting material is personally selected and inspected by Joe Sorrenti before it gets delivered to our job sites. For small to medium backyards, we often use synthetic turf for the remaining lawn area to prevent landscapers and lawnmowers from having to access the backyard. This will keep your backyard clean and private with little to no weekly maintenance. We also offer landscaping design and construction services
