If you like discovering new and exciting plants, East Timor and the rich flora of Malesiana is just a short flight from Darwin. You can join me on my tour of East Timor, 15-25th June 2020.
Malesia is a biogeographical region consisting of East Timor, Indonesia, Malaysia, Singapore, Brunei, New Guinea and the Philippines. Its tropical flora is even more diverse than Australia’s. Earlier this year, I found this beautiful but obscure Malesian plant while escorting a gardening tour of Vietnam. How can it be identified?
“Dear Jerry, my cocoa plants are infected with black pod disease. They are cropping OK, but can I do anything to improve their health?”, asks Peter in Townsville, Australia.
Hi Peter, Phytophthora is primarily a root rot disease and it can spread throughout a plant using the vascular system. Some plants are more susceptible than others and there may be multiple host plant species in your garden.
