Never mind - I think I found it: Elaeagnus umbellata

Plants well established in the ground - like yours - seldom ever need fertilizing. They get what they need from the soil. Only if you see some obvious signs of nutrient deficiency - off color or yellowed foliage, very slow or stunted growth - would you need to fertilize and then only after a soil test would tell you what was missing. IF you need to fertilize, fall is not the time to do so - early spring as the plants are pushing new growth is a much better time. Late season fertilizing can produce lush growth that is unable to harden off properly before winter, leading to cold damage. It is not possible to tell you when or how long to water. The need to provide irrigation is dependent on too many variables to be specific. The recommendation is long and slow watering infrequently, but you will need to test soil conditions and pay attention to the weather to determine when that might be appropriate. I live in a recurring summer drought area and few established landscape plants here will require supplemental watering even during our dry summers.......it just depends on the plant and the soil conditions. Newly planted trees and shrubs are a different set of circumstances. And IME, once the Alberta spruce has started to decline, they are difficult to recover a dense and lush growth. Lack of needle growth in specific areas generally signals some branch dieback, perhaps from insects (the mites) or merely from excessive shading or lack of air circulation. Dead stems will not regenerate healthy foliage.

With the red tints to the stem, you may be able to narrow the possibilities of which cultivar. For instance, it is unlikely to be Limelight. Hydrangea paniculata are one of my favorite plants for their unfussy care and long bloom season (3-4 months). Some cultivars can get quite large, so plan for that in figuring out where to resite them. They start blooming white, and they age to pink.

It'll flower in very early spring where you are. Maybe even blooming by Christmas.
