contact cropEstablished in 2010, Davley Organics grew by the hard work and dedication of brothers and business partners David and Nicholas Ings.

With numerous projects over the years, Optigrow comes about to include its two main divisions, organic soil heath and the production of worm castings and its macadamia tree nursery.

Launching in 2017 and with an ongoing interest in optimising the way we farm and grow sustainably, Optigrow looks to the future, a planting partner to our farmers and customers and a support were we can be to our communities in need.

Vermiculture is the conversion of organic matter into an extremely fertile fertiliser and soil conditioner with the use of Tiger Earth Worms, commonly known as Red Wigglers (Eisenia Fetidia).

The process involves the digestion of organic matter by the wriggly workforce and the resultant production of two fertlisers.
worm castings, the solid fertiliser, and Vermileacheate, the liquid extract commonly known as “worm tea”.

As a bulk suppler, Davley caters for the organic fertilisation and soil restoration needs of a variety of commercial concerns in Mpumalanga and further afield. These include, fruit, nut and veg production, landscaping and the retail garden market.

OptiGrow strives to meet the needs of all our clients.
worm castings are supplied by the cubic meter with retail orders for supply available in an option of 20 or 40 dm bags and commercial orders in 40dm bags. Vermileachate (Worm Tea) is available per 200l barrel.

The long term benefits of castings added to poor soils are that they will not only be rehabilitated to produce better crops but it will also bind the soil and improve its water retention properties which in turn will reduce soil erosion, a major issue in Africa.

Earthworms have an amazing ability to detoxify environments and rejuvenate naturally what would be near impossible to achieve by man alone.

OptiGrow and Davley Organics are growing from strength to strength and with dedicated focus on producing a premium product for our clients.
