Q. Azalea Disease on Leaves

I have a number of Azalea plants in pots that I’ve had for about 11 years. I keep them under shade cloth in the summer in an easterly direction and in the winter I put them in a round garden on my front lawn. They love it there and they always flower beautifully. I live in the central wheatbelt of Western Australia and our summers are very hot and winters are cold and frosty. This does not seem to worry them at all, but this year they have what appears to be a white to grey appearance on the outside of the leaf and on the under side little black spotted things. Please can you help, as I said the summer doesn’t worry them as long as they are under the shade cloth, and of course, kept watered and the cold frosty mornings when we have them in winter doesn’t bother them.

The problem could be attributed to the azalea lace bug. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/azalea-lace-bug.htm

Q. Winter Blooming Azalea

I have a potted azalea that is in a bay window and it bloomed in the last few weeks of Dec. and Jan. Could you explain why?

The conditions were right for it to bloom. Plants do not look at a calendar to decide when to bloom, they go by the amount of light they get, the temperature and the amount of water they recieve. For your azalea, you bay window was in mid-spring mode.

Q. Azalea Houseplant Care and Propagation

I need specific information on how to care for my Azalea and how to propagate it (and care for the cuttings) after it is established.

Azaleas can sometimes be difficult to propagatewith semi-hardwood cuttings, so be sure you take several if you go this route.Azaleas root best in winter, but you can still take cuttings now through summerfrom this year's growth. Remove all but the top 3-5 leaves, dip inrooting hormone, and stick in a 50/50 mix of sand and peat. Place the cuttingwhere it will get lots of light, but no direct sun, and keep it moist. In fact,it may help to put a plastic bag (with slit for breathing) over top. By next spring, you can move the rooted cuttingsup to individual pots and then transplant outdoors. They are also easilypropagated through layering. Gently bend a branch to the ground, pin it place,cover with a little soil, and set a rock on it. Check for roots at the end ofsummer, and then sever it from the mother plant, putting it in ground during fall.

Q. What Killed My Azaleas

I have had two evergreen azaleas for 5/6 years, both grown in pots and have previously given me an abundance of flowers every spring. This year the leaves on both turned brown and the whole thing died. I checked the soil and didn’t find any insect or grubs, no powdery mildew on leaves, no galls on plant, no holes of any kind on leaves, so I am completely baffled? Please, could you tell me what you think it could be, as I would like to replace them but need to know what killed them first.

Q. Why are leaves on my potted Azalea turning brown and dropping off?

Most likely, it is a watering issue. Water the pot for several minutes to make sure it is thoroughly soaked. Plants in containers must be watered daily, even twice a day if temperatures rise above 85 F.

Q. Potted Azalea

A friend gave me a potted azalea to “save.” Plant in good condition, although blooms are all wilted and look to be dying. Should I deadhead blooms? If so, how far down the stem?

While not necessary, it will not hurt the plant to remove the spent blooms.

Q. azalea has not flowered

For two years my azalea, which is in a pot, has not flowered. It is not pot bound and has been fed each year. Any idea why no flowers? Also, exactly the same question applies for my hydrangea which is in a pot. I have not pruned this as advised, no need, and it should flower each year.

In general, when containerized plants, either indoors or outdoors, fail to flower, it's because the light is insufficient, or there is too much nitrogen/too little phosphorous in the fertilizer. This article will tell you more about azaleas in pots: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/growing-azalea-houseplants.htm
Pretty much the same advice will apply to your hydrangeas.
