Dwarf conifer losing colour turning brown
Hi all - new to this forum but not to gardening but need some advice! I have 2 identical dwarf conifers Chamaecyparis obtusa Nana so I believe in one particular soil bed along with different conifers some are also dwarf. All of the conifers were only bought shortly before lockdown and both of these two were in a healthy condition - in fact identical. All have survived the exposure to the winds during spring and now the weeks of intense sun and heat except for one of the two I mentioned above by name. The other is fine as shown and only feet away from the dying one. I have brushed with hands some of the browng dead foliagebut it still does not look healthy! Can anyone explain this? Same watering same exposure!
