Root rot in grevillias

Started by Barrie - 2772 Saturday, 21 November 2015

What treatment if any is available for Grevillia root rot? Plant has been growing and flowering well for 2 years and now appears to have some die back at the end of branches.

If it root rot you may have some success with phosphorous acid commonly sold as phosacid under various trade names. See this article.... http://www.burkesbackyard.com.au/fact-sheets/in-the-garden/weeds-and-garden-pests/root-rot-2/.V3CdyKKGOJo
