|i have 2 poducarpus bushes on either side of my shed doors and they've been there for at least 15 years and i keep them pruned to about 6 feet tall. within a week, one of them has turned completely brown. any ideas why and what i can do? thank you.
|Podocarpus (southern yew) is susceptible to root rot caused by Fusarium, a
soilborne pathogen that invades feeder roots), and to Phomopsis, which is a foliar fungal disease. Root rot will cause sudden dieback; a fungal disease usually works more slowly but left untreated can kill a podocarpus. You'll find fungal spores on the leaves and stems of the plant if Phomopsis is the cause. There's nothing you can do for the dead shrub but you'll want to remove it from the area to protect your other podocarpus from splashing or windborne spores. Good luck with your plant!
