Question
Hi,

Thank you for your answer to my question. Though - shade loving? Really?! The tag says full sun to partial shade (they are hot shot azaleas) I bought 7 of them and the three in the back are in full sun and look awesome - its just my four up front that I am struggling with. I will try some acid fertilizer and see what happens. Do you think I should transplant them?

Thanks again!!!
Nikki

I have 4 Azaleas that are droopy and turning colors (purple/red leaves) I know that they have plenty of water, but they just don't look happy. They are in a good amount of sun and good dirt. Any ideas as to what I can do to save them?!

Thank you

Nikki,
I must admit that the description of purple leaves had thrown me for a loop. Reddish leaves usually indicate a rust disease that attack azaleas and rhododendrons, for this you need to apply a fungicide that is labeled for this disease, this application needs to be done in the spring before the disease has a chance to damage the leaves. Fungicide applied now will help protect any new growth that the plants will put out.
I think that the problem is compounded by the fact that  azaleas are a shade loving plant that a probably planted in full sun (this is a very common mistake made by many homeowners and landscape architects).
You wrote that they are in good soil, but what is the soil like underneath that good soil. Is the drainage in the area that they are planted in adequate or is it poor? If the water is pooling up in the root zone, then the roots may be being drowned out, this would also cause the leaves to droop.
I think that your best bet at this time is to feed them with Muracid (azaleas thrive in acidic soils), and cut back the water to two to three times a week for 30-40 minutes (long soakings are preferable to light sprinklings to establish a deeper stronger root system).  

Answer
Niki,
I stand corrected- the newer cultivars of azaleas are bred for full sun to partial shade, as the tag says.
Transplanting the ones that are struggling could cause their condition to beome worse, especially at this time of the year.
You may also want to check the undersides of the leaves for any insect activity. Lace bug and whiteflies will attack plants under stress before moving to healthy plants.
I would recommend feeding them and adjusting your water for the time being. This should help to bring them back.
