I am seeking help A number of my Leptospermum scorpariums ( Manuka ) 70 in total and most are approximately 6ft in height that my bees feasted on The trees are slowly dying it is very hearbreaking to watch after nurturing them from seed in cell like trays . Initially I thought that the drastic weather changes and conditions may have affected them, however they are a hardy frost and drought resistant plant ,but slow growing I started to notice during the summer that the tiny spiky leaves were losing their color . Upon closer inspection the leaves were brittle stems were brown and this quickly spread to the rest of the tree After dissection I have found that the stems were hollow and brittle . The plants promptly died . Approximately half have died I have many manukas in various stages of growth a , now I am concerned I might lose them too if I plant them .
It could be Armillaria root rot. The only recourse is to remove the stricken trees to prevent its spread. We suggest consulting with a nurseryman or arborist for a definitive diagnosis.

Hi, I have a mature Leptospermum madidum - weeping tea-tree and would like to relocate it from the backyard to our front yard garden bed. Will it survive okay if we digup large root base. Thanks
There are several steps to moving a large tree. It takes time and planning.

out. What can I do to save the plant? The plant is exposed to the sun all day every day. I live in southern California, inland where it is very dry. At first I thought maybe this issue was a result of freezing but as time has gone on, It appears that the issue is more systemic as the center and all its branches are effected. There are two lateral branches that are healthy still. The tree was planted in June 2012. Is on a drip system watering 3 times a week. For a year I deep watered it once a month hoping that would help. No difference I could detect. I also applied organic fertilizer which made no visual difference. It hasn't had flowers for years now.
You may want to do a soil test to be sure that your soil is acidic enough for this plant. Your soil also needs to be well-draining and fertile. This plant should be fed monthly with a balanced fertilizer, like 15-15-15. Your garden nursery folks will advise you about which granular fertilizer to use.
