Part of proper irrigation is good design. We install drip irrigation as well as sprinkler systems creating irrigation specific to your garden needs.

J. Walter is a licensed irrigation/backflow company.


Good soil preparation is the foundation for a healthy and vibrant garden. We hand til organic amendments enriching soil biota which lowers costs from maintenance, pesticide use and water while at the same time preventing disease.


The majority of the time we use a steel flat bar edging. Often times there are also re-used materials found on site like stones also used for edging.


We prepare each plant individually for planting by using beneficial mychorrizea encouraging healthy roots ensuring quick growth and longevity for your entire garden.

  • Low maintenance plantings
