Does anyone know of a fungus-resistant olive tree?
Olive trees are susceptible to verticillium wilt. ‘Swan Hill’ fruitless olive is grown on a verticillium wilt-resistant rootstock, called ‘Oblonga’. It’s available from Swan Hill Nurseries (a wholesale nursery in Arizona). You can go to their website (www.swanhill.com) and scroll down on “wholesale-retail outlets” to find a retail nursery in your area that sells ‘Swan Hill’.
