Natural Catastroph And Recover Operation
Two winters ago, weather was cold. Ten nights was under freezing temperature, I lost four Michelia alba plants. My recover operation was to apply approaching graft methods to produced two new grafted plants last year. I just made ten more approaching grafts this year. Hopefully my M. alba plant shall be not extinct from my backyard.
Approaching graft is a fool proof method by introducing a magnolia plant to tie their branches together( both branches are cut to about 1/3 longitudinally to match them side by side). After a few months, a new grafted M. alba is here. I even have the flowers buds on the small branch.
