Integrated Pest Management: Compost Tea

 

Real Compost

WHY  Many of us now understand that healthy soil is the foundation of a healthy garden.  Beneficial bacteria and fungi in the soil partner with plants to bring them water and nutrients in exchange for exudates–sweet carbs that the plants release from their roots. Micro-organisms may also provides protection for the the plant in the root zone, by out-competing, killing and warding off less beneficial organisms. These very same bacteria and fungi can be brewed up in a tea and used to protect the above ground part of the plant. Spraying compost tea  on the leaves (called foliar feeding) inoculates the plant with beneficial micro-organisms that colonize the leaf pores to protect from  pests and pathogens.  Through this action, these same micro-organisms ensure themselves first dibs at decomposition dinner when the plant dies.  Foliar feeding can be done safely on a regular basis as a preventative, or at the first sign of a problem.

HOW  Put about a gallon of finished  living compost in a 5 gallon bucket.  Add a goodly dollop of molasses. Fill will water that has had the chloramine removed (a product for fish tanks and ponds will work well for this or use rain water). Place an air stone bubbler in the bucket and  run it for 24-48  hours (chloramine remover, airstone and small aquarium pump can be purchased in the fish supply section of any pet store).  When ready it smells fresh like compost. Strain through a fine cloth and spray it onto your plants.You may also use this as a soil drench to inoculate the garden beds or compost pile with beneficial microbes.
