Environmental Impact

Plant Production
      Mercer Botanicals grows and supplies high quality air purifying machines. Some of the products we grow were tested and promoted by NASA to help reduce toxins like formaldehyde, benzine, and ammonia. Apart from cleaning your air in a home or office other studies have shown an increase in memory and concentration. 
 
 
Water and Fertilizer
       Mercer Botanicals over the years has made a mission to become more water conservative. All houses built after 2000 have been put in with low volume overhead irrigation emitters and low volume dripper tubes for hanging material. A professional study was done to find out the output and accuracy of our new and old irrigation systems. From the information gathered we are working to replace the old irrigation systems and improve our accuracy to over 90% in all greenhouses. With doing all of this work Mercer Botanicals has drastically reduced the amount of water use per year while increasing the accuracy of liquid fertilizer applications, eliminating runoff. In an additional effort to reduce the amount of liquid fertilizer Mercer Botanicals incorporates or top dresses a 180 or 360 day slow release fertilizer into all soil mixes.       
 
 
Biologicals
     Mercer Botanicals controls its pests with Biological Predators or Biological insecticides on over 60% of its crops. We are working every day to increase that number.  
      Mercer Botanicals has been experimenting, and actively using biological predators for over 15 years. The predator Mercer Botanicals has had the greatest success with is the Phytoseiulus persimilis. It is the most aggressive biological predator against the Two-Spotted Spider Mite, which is Mercer Botanicals biggest pest problem. Crops like Calathea, Cordyline, Maranta, Neanthe Bella Palm are all grown using P. persimilis which covers 50% of all crops grown that have constant T.S spider mite issue. 
      Crotons and Dieffenbachia have proven to problematic to have a good P. Persimilis program due to other pests feeding on these crops. We are constantly trialing new methods and working with consultants and beneficial suppliers to create a solution. Currently 60% of our Croton production is being treated with a predator/chemical hybrid program. We also are successful at using predators on 60% of our Dieffenbachia production.
