|Could someone tell me if my azaleas will be able to tolerate the location I have recently moved them into. They are in on the south side of my front lawn where they get full sun from in the morning until late afternoon when some maples (when in leaf) start to shade them. The azaleas are Crimon Red, Rosebud and a variety of Kurume azaleas (all are evergree). My zone is 7a (most winters see a minimum temp of 10. F and summer maximum is around 98F..), with a fair number of humid and cloudy days. Thanks.|
|If you mean Hino-Crimson, it is noted for sun tolerance and red winter foliage. |
Rosebud should be OK as would be most Kurumes.
More sun stimulates flowering and but may trigger lace bug infestations. Whitish specks on the upper surface of leaves and dark spots varnish-like on the bottom are symptoms of Rhododendron Lace Bugs, Stephanitis rhododendri, and Azalea Lace Bugs, Stephanitis pyrioides, small insects with transparent wings on under-surface of leaves. This insect hatches early in spring as the new foliage begins to mature and its numbers may build to damaging levels with successive generations.
Lace bugs reach their peak in late summer and do their worst in sunny, exposed sites. Spiders are important predators of lace bugs and since they shy away from sunny, hot places, plant your azaleas where there is some shade. Insecticidal soap, horticultural oil, or a systemic insecticide may spare your azaleas the damage if applied in spring when the first hatchlings are noticed. Care must be taken to spray the lower surfaces of the leaves where the lace bugs live.
Moving a plant to an area with more shade may alleviate the problem. Lace bugs are more prevalent on certain varieties.
The following azalea cultivars have resistance to azalea lace bug: ´Dawn,´ ´Pink Star,´ ´Ereka,´ ´Cavalier,´ ´Pink Fancy,´ ´Dram,´ ´Seigei,´ ´Macrantha,´ ´Salmon Pink,´ ´Elsie Lee,´ ´Red Wing,´ Sunglow´ and ´Marilee.´
