I already wrote this a bit ago but I guess it did not get posted... So here it goes again.
Well I have been trying to grow a juniper bonsai for 4 years now with no luck. I am new to this art but I read a lot and love to learn. All my other trees are good and growing, but my procumbens nana junipers will not grow in containers! (The one in the ground do great).
Here is the situ>
They are in full morning sun and shaded in the afternoon. I have my trees planted in a well draining soil 40-50% black lava cinders (2-3mm in diameter) to 50-60 % organic matter sieved to about 2-3mm. They are misted in the early morning before the light hits them. I keep the soil only slightly moist, never letting it dry out completely. I fertilize with a solution of 5-10-5 about every 3 weeks.
Here are the symptoms>
First I notice slow or no growth. Then the trunk base and visible roots start to develop a pale orange crust. Next the bark starts to appear wrinkled like a raisin. And finally the leaves turn pale green, dry and fall off.
I suspect that it is root rot...But I am not sure. I feel that the watering regime is good as well as soil and things so root rot could not be the case....?
If anyone can help I would appreciate it very much!
Thanks.
