    Zone 5 is normally the coldest end of their winter hardiness. Many azaleas grown in Zone 5 may not be evergreen; they may lose foliage and-or branches above the ground unless you grow them in containers and bring the containers into a protected location during winter (basically a location where temperatures do not drop much below 20°F). If you're in Zone 4 and just have to try an azalea, Wilson Bros. Gardens recommends to plant in a site that provides at least 6 hours of direct sunlight per day during the winter and insulate the roots in late fall with a 4” layer of mulch past the drip line that is removed when temperatures warm in early spring.

    You may want to consider the Stanton Hybrids, a.k.a. the Great Lakes Series. They were developed in Grosse Ile, Michigan. My contacts at the Azalea Society Of America indicate that, for a source for these azaleas, you might try Mr. John Migas, a nurseryman in Saugatuck, MI. He also would be an excellent source for other evergreen azaleas that you might want to try. He has an extensive selection. His E-mail address is azaleajohn@yahoo.com.

    Another possibility is to consider azalea cousins called rhododendrons. Some good choices for z5 are the rhododendrons that belong to the Northern Lights Series. These plants were developed and released by the University of Minnesota Landscape Arboretum. Northern Lights rhododendrons are not just borderline zone 5 rhododendrons. They are hardy in regions where temperatures drop to -30 degrees to -45 degrees Fahrenheit. If you want pink flowers, consider “Pink Lights” for pale pink; or “Rosy Lights” for deeper pink; or “White Lights” for pink buds that open to white flowers; or “Spicy Lights” for unusual salmon colored flowers; or “Orchid Lights” for ivory colored flowers.

    It looks like a reblooming azalea. The plants look kind of leggy. They might do with a pruning. Here is how:

    Planting shrubs in fall is typically fine if you have about six weeks left before winter frosts. That gives the roots time to get established. If you are about to hit winter, I would hold them over in the garage till spring, just watering lightly about once a month. If you go ahead and plant be sure to mulch well. Also, azaleas need a site with acidic soil. Here is more:

    I used a systemic insecticide for azalea lace bugs when my problem occurred. The mottled look of the foliage will persist until the leaves are shed by the plant at a time of its choosing. You can fertilize the azalea during the growing season as usual: start fertilizing after your average date of last frost and stop fertilizing with a slow release fertilizer three months before your average date of first frost. Please repost with many pictures of the two problems that your ornamental apple tree has (the white fluffy stuff and the dead wood) as much more details of both problems.

    f they are blooming well and you have no need to control the size, I suggest leaving them. If they are leggy or you want them shorter, here is a good article on pruning, but you sure have your work cut out for you if they are all around the property. Maybe only do a third of them each year for three years. Also, be sure to wait till after this year's bloom to prune, or you will cut off all the buds.

    We don't recommend products or vendors, but I did a search and found out it is part of the Northern Lights series, bred by the University of Minnesota Landscape Arboretum. It is one of the hardier varieties which I suspect is why you want it. Have you asked at local nurseries if they can get it for you?

    You could do some cleanup like removing broken, dead, or crossing branches. That should help. You could be a little more daring on the encores, but It would be best to wait on the Gumpos. The best time to trim Encores is right after the first spring bloom.
