Wax jambu ID problem

[gozp]

I had this macopa for a year now.. i noticed that new growth always seem to die back..i was wondering what could be the cause?

Here are a few culprits i have in mind

--Leech climbing to the newly shoot leaves
-- some kind of insect
-- sun damage??

My wax Jambu is doing the same things. 
They slowly died back all the way to the trunk and kill them. 
I had one died last year and the second one almost died to the base and I cut it off and put in the smaller smart pot, the root still have some white roots. 
I hope I can make it survive. 

One more thing is the tip on the leaves always dried too.  May be we have the dry weather in California?

I looked closely at the photos and I didn't see any insect or pest damage. When plants start to decline in growth, I usually go back to the basics (sunlight, water, fertilizer, and soil). I may not be of much help because I have to grow my wax Jambu in pots because I have oak root fungus in the soil. I keep mine in part shade when they are small, because the leaves can sunburn easily at that time. I also keep them very moist from April to Novemer with a good amount of mulch. If you have clay soil, you should use fertilizers with micronutrients. Some of the close up photos look like the leaves are sunburned and could use some extra water and are missing some micronutrients in the soil for good growth.

Looks like you have some soil born fungus problem and the mottled damaged young leaves are probably thrips damages. In So Cal, they look like mosquitos and hang around branches.

My diagnosis is it was dehydrated.

Upon digging it out from the ground, roots in the bottom were dry.

I had potted it & now its thriving.



Not to mention leafhoppers
