Lukas, our Head Agriculturist, obtained his M.Sc. Agric in Horticulture from the University of the Free State in Bloemfontein. He joined the Rotondo team in 2004, where he has been dedicated himself to becoming Africa’s premier walnut specialist. His scope of interest includes Irrigation Scheduling, Integrated Pest Management, Pruning, Fertilisation and is leading our move towards Regenerative Farming Techniques. Lukas likely loves walnut trees more than anyone in the world.

Howard

Howard is another walnut variety cultivated in California in the late 20th century. We harvest our Howards during the middle of the season. They produce a large, round smooth nut with a good seal. Tree size is small to medium and semi-upright with moderate vigour, which makes it a good candidate for high-density plantings.

Serr

Our Serr trees are harvested early during the season. They produce large nuts, with a good shell seal and a high kernel to shell ratio. Serrs manage well in shallower, heavier soil. They require less fertiliser and can survive hot climates, but should not be planted in areas where there is a risk of late frost. They are fast growing large trees that require good spacing to thrive.

Chandler

The Chandler cultivar was developed in California in the late 1970’s. Our Chandler is a highly fruitful vigorous tree with fewer pest problems than other cultivars.  Their walnut is large, smooth, and oval shaped with a good shell seal. Chandlers are well known around the world and are highly prized by buyers for their extra light colour and high quality kernels. Harvested mid to late season, Chandlers provide one of the highest kernel yields of any other tree. Worldwide, the Chandler walnut is the most prolifically planted walnut worldwide.
