Native Texas Nursery – Weed Elimination, USA

” We were fighting a losing battle against weed seeds and plugged sprinkler heads for years. We purchased and installed two Filtomat filters last fall and in just one spring, they have already paid for themselves (and then some) in labor savings. We freed up manpower for other tasks and have seen our weed issues go from plague status to almost non-existent. This is one of the best investments we have made in our facility. “

Background

Native Texas Nursery is a 40 acre nursery that provides native plants to Texas garden centers,
landscapers, architects, municipalities and other organizations. The water source for their plants is
a pond on their property filled by wells.

The Challenge

The pond providing the water for the nursery became contaminated with weed seeds by natural
infiltration. These seeds were transferred to the pots around the nursery by the irrigation system
(drip, micro spray, impact and shrub heads). The weed seeds grew and thrived in the pots along
with the desired native plants. All the weeds had to be manually removed from the pots to preserve
the quality of the native plants.
During worst case conditions, in the Spring of 2016, the nursery employed six full time staff
members whose sole job was to remove weeds from the pots on the property and to control weed
growth around the pond (to attempt to reduce further weed distribution and growth).
Native Texas Nursery approached Amiad during a local trade show which began the process of
finding a solution for this issue.

The Solution

The nursery has two main irrigation lines, both supplied by VFD pumps to provide a constant
pressure of 70 PSI. One line distributes 300-400 GPM and the second distributes 200-300 GPM.
The Amiad staff recommended 130 micron filtration in order to remove the weed seeds and to
protect the irrigation system from other contaminants from the pond which could clog irrigation
sprayers or heads. A Filtomat M106XLP was supplied for the larger system and a M104XLP for
the smaller system. Both were supplied with an electronic control system. Each Filtomat filter
allows for flow fluctuations and changes in water quality over the seasons.
The filters were installed in February of 2017.

The Result

Since the installation of the two filter systems, Native Texas Nursery has had zero incidences of
weeds growing along with their native plants. A single staff member is still tasked with checking
for weeds for a few hours each week and to control the weed growth around the pond. The reduction in staff alone from the 2016 to 2017 growing season has saved the nursery close to $36,000.
This resulted in an ROI in less than one year.
Emily Brown, the general manager had this to say about the Amiad filters:

and then some – in labor savings in just one spring. We freed up manpower for other tasks and
