Can photinia and palms be planted at this time in Tucson or should I wait until the fall? We are starting to get our 100+ degree days.
If you can, I would wait. That kind of heat stress is sure to put them into transplant shock.
If you have to plant now, water, water, water and try to give them some shade. Setting up a temporary canopy over them or some other cover will be helpful.
Is the photinia bush deer resistant? I live in the foothills and deer are always in my yard. If they are not deer resistant, can you recommend another bush? I have considered oleander, but I am not too fond of them.
Unfortunately, these are not deer resistant. However, you could try placing deer-resistant plants around the perimeter of your home or even protect the shrub with a cage. Deer usually steer clear of any plant that is fuzzy or prickly, extremely aromatic, or excessively tall or short.

I have a row of several photinias, three that are over 10 feet tall. One of them seems to be dying, as it looks droopy and is dropping all of its leaves. What could be the problem? I live in Monterey County, Calif.
Photinia is very susceptible to the fungus leaf spot, called Entomosporium, that can defoliate photinia plants. Plant photiniain full sun and provide good air circulation. Remove and destroy fallen leaves, prune off diseased twigs. Avoid overhead irrigation. Fungicide sprays (copper-based products) are also generally necessary for this disease, beginning from bud break and applied every ten to fourteen days until all foliage has matured. Mature foliage is no longer susceptible to infection. Not sure if this is the problem (wouldn't be water issue as the others are seemingly ok), but treating with fungicide wouldn't hurt. It may actually help prevent it from spreading to the other shrubs if it is in fact a fungal issue.
I have a hedge of photinia. We have had 20+ days of rain here in NJ. About a month ago, the photinia developed the fungus your website describes. How do I treat the fungus? Please advise as I am desparate.
Treat the plant with neem oil. It is both a fungicide and a pesticide. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
Two of my Photinia bushes are turning brown and look like they may not make it. Do you have any suggestions?
What is the pattern to the plant turning brown (i.e. bottom up, all over, etc) and how old are the plants? This will help us determine what this issue might be.
I have 2 red-tipped photinias about seven feet tall that are growing close to a concrete wall on one side. They get sun at least 8 hrs. per day. They do not have leaf spots but some of the leaves are without color - some maybe 1/2 green and 1/2 white - like the color is literally being drained out of them. Is this a disease or could it be a watering problem? I don't see any bugs on the plants, and they otherwise look healthy. We recently had 2 weeks of wet weather, which is the opposite of our normal weather pattern - hot and dry (southwest Oklahoma)! Any help would greatly be appreciated because I don't want to lose them.
Is your soil alkaline? That's a common cause of chlorosis in photinia. Try adding some sulfur to the soil.
I want to root photinia cuttings. Should I use new growth cuttings? What do you consider the best method to get them to root? What root stimulator (if any) should I use? Any other advice?
