Oserian was one of the first flower farms to venture into large scale rose farming

Eco Friendly
Since 1969, we have been guided by the principle that there are almost always environmentally green alternatives to its everyday farming techniques and operating processes.

  • Green Power
    • Well 306 and Well 202
    • Green power is based on a practically clean and limitless resource-natural heat from within the earth and has significant environmental advantages.
  • 3
  • Green Heat & CO2
    • The Oserian Heating Plant at Well 101 creates the heating capacity for production from an environmentally sound renewable source
    • The heating allows for greenhouse climate control which ultimately allows for a reduction in chemical and pesticide usage – green production

  • Green Production

    • Hydroponics – over 80% of the crops
    • IPM – over 50% ha of flower production
    • Heating to reduce Botrytis and Downy Mildew
    • Drip Irrigation – water conservation and management
  • 5
  • Green IPM

Predatory insects are used to biologically control the populations of common agricultural pests such as white flies
Working in conjunction with the REAL IPM Company and Kopper Biological Systems, we run the largest IPM project in the world and continue to be ahead of other rose growers on the implementation of IPM practices
Over 150% of flower production out of its 216 hectare are under IPM

  • Green Recycling
    • On-site recycling plant has generated a host of environmental, financial, and social benefits
    • Old plastics from greenhouses are recycled to make fencing posts, plastic flower support and benches for the schools from the recycling plant
    • Reduce, Reuse and Recycle are the three Rs that guide Oserian activities and process at each stage
  • 7
  • Green Conservation
    • The farm is commited to improving and sustaining the natural habitat
    • 18,000 acres of its estate is dedicated to a wildlife sanctuary and native vegetation
    • 3,000 acre wildlife corridor established across the farm to allow safe, free access, and movement of wildlife between Hell’s Gate National Park, Oserian Game Corridor and Lake     Naivasha
    • Flagship species include the vulnerable White Rhino, the endangered Grevy’s Zebra , Black Rhino and Leopard
    • Over 300 identified bird species, including the largest population of endangered “Grey-crested Helmet shrikes” in the world and 45 different mammals such as Leopards, Lion,     Buffalo, Serval cat, Genet cats and Aardvark
    • The farm introduced non-indigenous species such as the Beisa Oryx, Greater Kudu (trans-located from Northern Kenya), Wildebeest and Topi (from the Trans-Mara region)
    • Excellent working relationships with partners such as Kenya Wildlife Service, World Wildlife Fund for Nature, Moi University Wildlife Department and the Kenya Fisheries in conserving     Lake Naivasha and its surrounding environs
    • From 6 introduced White Rhino in the mid 1996, we now have 12 Rhinos and currently 4 of the females are suspected to be pregnant

  • Green Forestry
    • It is estimated that Kenya needs to plant more than 100 million trees per year to meet its demand and restore its forest cover
    • Trees, shrubs and vines are an integral part of Oserian landscape, providing wildlife habitat, beauty and shade
    • There are currently over 3 million indigenous and exotic trees across the farm
    • A forestry and nursery programme is part of an established Environmental Management Plan
    • To this end, a wide variety of over 17 indigenous tree species have been planted and the project continues to grow each year
    • Oserian won the prestigious Total Eco Challenge award, for its green forestry programme, in the Bronze category in 2006 and a Silver Award in 2007
