Hi everyone, my name is Andy and I live in Hong Kong. It is unfortunate that my first topic has to be about an unhealthy bonsai.
I bought a Ginkgo bonsai a few months back (at a bargain price), so I am not sure the plant would be the best possible specimen already. The plant seemed to survive for quite awhile in its original soil, which was this more organic soil as opposed to bonsai soil and it seemed like the store had recently repotted it and trimmed some of the roots.
Well fast forward a couple of months and it was doing fine until a recent hot weather wave in Hong Kong.
Now I've read some conflicting information regarding the watering for the plant with some sources recommending lots of watering during the growth period and others recommending it be more dry. I initially kept it moist though not as wet as I do for some of my other plants and do let some water dry out.
It started to have some dryer yellow leaves and I've been trying to help it recover since.
Some of the top leaves are still healthy and green, though some appear to have begun to get some yellow blotches (almost like polka dots of yellow) on their leaves.
I've attached some pictures. Could someone please help me diagnose the problem? Some of the browned leaves were already that way when I got the plant and the leaves were still green.
Is it a watering problem? Too much fertilizer? Not enough sun? Disease?
I'm just hoping it can make it to winter and then recover through its dormancy.
Thanks again for your help.
