The leaves of the beech are scarce, I am worried that the tree will die
The leaves of the beech are scarce, and the leaves are reddish and yellowish. The whole tree has no vitality and feels very weak. I am worried that the tree will die. Three trees were planted together. This one is very different from the other two trees. I don’t know how to improve the condition of this tree.

Blueberry plant with shade in fall/winter/spring, but sunlight in summer
I understand that blueberry plants need full (or mostly full) sun, but what about a location right next to an (opaque) fence on the southern side such that during the summer -- when the sun is more directly overhead -- there is full sun, but in the fall/winter/spring -- when the sun is lower in the sky -- there is shade?

Waxy substance on ficus leaves
I have a waxy substance on the undersides of a 25-year-old ficus tree. It has been in the same window for seven years. Have never had a problem. It does not go outdoors in the summer. I would hate to lose it. I’ve tried an organic insecticidal soap. I have read online where someone else tried neem oil with no results. Any suggestions?
