White pines are dying

I have 2 small white columnar pines.  One died over the winter and the second pine does not appear to be doing very well.  While the needles are still green, the tips are tinged with brown.  The top is singed…

Is it dying?

Hi, I notice that this bush (sorry, I don’t know what it actually is) is brown from the bottom. Is it dying? What should I do with it? Many thanks.    …
