Did I get the wrong Encore azalea?
Comments (5)There is certainly an advantage to the suggestion of buying plants only when they are blooming. I am glad that HD made you an acceptable offer and am glad that the plant is a rebloomer. I once bought a rose that blooms only once a year (so it is not a rebloomer) and I purchased it while it was not blooming. Weeeell, I had the same issue as you did but the nursery did nothing because I did not contact them "early enough" (I had to wait until Spring of the next year to see that the blooms were the wrong color). Not even a discount on future purchases. Oh well. Live and learn... I learned to be more cautious with shrubs that bloom only once a year or that are not blooming until after the plant nursery's warranty expires. Enjoy your Rouges and Sunsets. I have an Autumn Royalty. I considered some of the orange-y ones but had a hard time finding a good spot for the orange blooms, which is how I ended with AR instead....See MoreEvergreen, reblooming substitute for Encore Azaleas?
Comments (2)If you do come to accept a deciduous nature for this project then there is shrubby potentilla, shrub roses and the new Sonic Bloom weigela varieties. The departure from promised expectation with the azaleas depends on what the specific basis was for claiming USDA 6. With it rather often seeming that plants are listed as being hardy "to" a zone that is really outside of their tolerance range. With this assertion being based on what the top end of the average annual minimum temperature for that zone has been said to be. So for instance maybe the azaleas you bought have been seen to burn up at 0 degrees F. and that became translated into them being "hardy to Zone 6" (average annual minimums 0 to -10 degrees F.) Just how cold it got at your place last winter would of course be relevant....See MoreEncore Azalea Advice: Too much sun?
Comments (2)I suspect its root system was not quite ready for the outside world and may perform better if the soil is deeply watered and always kept evenly moist at all times. That means not dry but not wet. Reviewing your temperatures, they were not terrible and the brief spikes to 95°F were brief. If you tend to water based on a schedule (certain days or every 'x' days), that will not work at first. You may need to test the soil moisture daily in the mornings at a depth of 4" (use a finger) during the summer months in order to determine when to water or when to skip watering so the soil is always kept evenly damp/moist. Use enough water to reach down to a depth of 8" (water the soil, wait for the water to percolate and then test the soil). I have Amethyst Azaleas here in Texas, z8a, and once established (that is a fuzzy term that means anywhere from 1-3 years), it has not had issues and survived extreme damage from February 2020 with flying colors. The plant broke dormancy early and started blooming just as temperatures crashed to -2°F. After pruning areas subjected to bark split, it was blooming again by late summer. My summer temperatures are hostile, over 100°F daily from June through September so I provided some afternoon shade. Another neighbor has another variety that gets only noon, afternoon and evening sun until 9pm. Neither has shown leaf symptoms of too much sun. I consulted their website (provide your zip code; click on 'look up zone'; click on 'Autumn Carnation') and it indicated that for Brooklyn, it can be in full sun. I would not plant near the azaleas as they have very shallow, fibrous roots, about as deep as 4" at first. I would keep the dahlias away from them even though their tuberous roots will not present a problem if properly spaced away. The literature for Carnation says its spread is 4 feet. I am not quite sure if a lack of evenly moist soil and/or a lack of deep enough watering may have caused a watering issue that caused leaf loss but be aware that when this happens to me here, they get new foliage by spring without pruning. The plants simply go semi-dormant and do not produce new leaves if temperatures are too warm. Finally, review the area where the pants are located too and see if there is sunlight that might bounce of cemented/bright surfaces and help cause "too much sun". https://encoreazalea.com/the-collection/resources-find-your-zone/...See MoreWhat is wrong with my Encore azaleas?
Comments (9)Zone 6a is the minimum Encore azaleas will tolerate and not all varieties are equally hardy. A hard winter freeze or late spring cold snap could certainly impact flower production. As will a failure to water adequately in late summer or early fall when latent flower buds are set. And take the "reblooming" concept with a grain of salt :-) The primary bloom season is spring and IME, you will get only mild flushes of rebloom periodically during summer or fall. And that is under the best of circumstances, including a proper soil pH and sufficient sunlight. Just a note of clarification -- while rhododendrons and azaleas are closely related, there are differences. The PJM group are rhodies, not azaleas, and one of a handful of broadleaved evergreen shrubs hardy in zone 5....See MoreBumblebeez SC Zone 7
