Why are the lower branches dead?
The most likely cause is a needle cast disease, rhizosphaera, which will continue up the tree. More details are at https://extension.umn.edu/plant-diseases/rhizosphaera-needle-cast. An ISA certified arborist could confirm the diagnosis or samples may be submitted to the Plant Disease Clinic at https://pdc.umn.edu/.
