Our garden is infected with phytophthera I think. I have had sudden death of daphne, golden nugget frangipani, box hedge, velvet and cream magnolia, scleranthes and boronias. The literature explains about how the fungus moves through water and how important drainage is. My garden sits on clay. Are there any companion plants that discourage fungal attacks? I still have surviving plants of each of the plants that were hit, I am spraying with foscheck and sometimes copper.

You’re on the right track with the spraying and improving the soils drainage adding in Gypsum to break down the clay is going to help too. Companions for phytopthera are really only planting Horseradish. Your main solution is to do what you already have in place.
