  Soils and Water
    Gwen Quail   


Gwen Quail gave this presentation at the NCNH District Business meeting in 2018 and it was excellent. It is a “show and tell” presentation with bottles of soil and water showing the soils diffusion. What are the main components of soil, how is soil formed, the physical properties of soil, how water moves in soil…these are just some of the areas Gwen will be covering. She will also be addressing health hazards when working in soil. Gwen is with the Butte Rose Society and was President of that society. She is a Consulting Rosarian. Her educational background  includes a B.Sc.Agr. from Sydney University.

Rose Rosette 

Joe Truskot


Rose rosette disease, also known as witches’-broom, is caused by a virus  (Emaravirus sp.) that is spread by a very small, eriophyid mite. The disease is limited to plants in the genus Rosa but R. setigera, R. aricularis, R. arkansana, R. blanda, R. palustris, R. carolina and R. spinosissima are believed to be resistant. Its main host is the multiflora rose. Interest in rose rosette has been generated by the threat to garden roses and its possible use as a biocontrol for multiflora rose. Joe will be presenting this complex disease with a PowerPoint and has stated he will let the photos speak along with the new research instead of strict academics. Joe will have copies of his book Central Coast Rose Manual.
