In the topic “Dark brown foliage on Itoigawa Juniper” I described how my juniper lost 70% of its foliage due to a fungus.
After a treatment in the end of may the fungus receded completely, the tree lost its foliage (=years of work) and new juvanile foliage came out.
3 Months at 82F-89F (28C-31C) without a problem.
Now the juvanile foliage is turning yellow and honestly don’t have a clue on what it is going on:
- is this color normal for juvanile foliage?
- is the tree discarding the interior needles even if the foliage is scarse (see picture) or the color looks like a problem (fungus) going on?
The picture shows needles turning yellow while the mature tips look intact.
- do you suggest to cut the long shoots to allocate energy to the rest of the foliage, promoting more mature foliage or cutting the arrows away would harm such a delicate tree?
