Your azaleas look like they are struggling and we notice reduced growth. Some reasons include poor soils, poor site conditions, insect issues such as lacebugs, etc.
You did not mention where the azaleas are located and how you care for them. In general, azaleas grow best in morning sun and afternoon shade in an acidic, well drained soil. If they are located in full sun they will require more moisture during dry periods and be susceptible to possible lace bug damage, a sucking insect. Avoid planting these shrubs in poorly drained compacted soils, low areas that collect water runoff, and locations near downspouts. These sites will often cause root rot issues.

You can prune the shrub back in early spring before new growth appears. However there will no blooms possibly for several years. Here is more on renewal pruning. https://extension.umd.edu/resource/pruning-shrubs-and-hedges
Even if you renovated the shrubs, they will continue to struggle if they are located in the sun in poor growing conditions. They will be also be susceptible to lacebugs.
Depending upon your site and growing conditions we recommend replacing the shrubs with other species adapted to the site, sun or shade and mature height and width of the plants.
For example, if you have full sun consider glossy abelia (dwarf cultivars), chamaecyparis, etc.

We are glad to hear that you are interested in landscaping with native plants for pollinators and that one of our MD Extension trained Master Gardeners is helping.
For your azalea situation, morning sun is ideal. Check to make sure that your mulch is no deeper than 2-4 inches and is pulled away from the trunk/stems of the plants. Too much mulch can smother roots of trees, shrubs and other plants.
