I am trying to get information on the proper time to prune my photinia hedges. I am located in Western Oregon where we periodically have freezing temperatures from November through February. Especially in December and January. I have one researched one site that says to prune in the dormant winter months. Another says to prune no later than the end of August if there are freezing temperatures expected. I am currently and have for several years been fighting black sport disease. The plants typically look great through the end of March and are a bright red for a short time. Then the black spot disease appears and my 5 hedges get infected to various degrees. What do you suggest?
Prune after mid august.

Is there a plant in this range that does not produce a white flower, only the new red growth. Many thanks... Susan
If a plant that looks like a photinia does not produce flowers, it is most likely a photinia that is not flowering for one of the following reasons:

hello, I was wondering if you can help me. I would like to buy Photinia x fraseri (red robin / Christmas berry) and I was wondering if the berries are toxic I have two kids so I need my garden safe thank you
Red-tipped Photinia and Christmasberry are 2 different plants. California lists Christmasberry as toxic to humans. Photinia x fraseri is not toxic according to UCanr.edu
Our house is on a street corner. A sidewalk follows a 6 foot block wall that runs along our back yard. The sidewalk grade is higher than our back yard so people walking along the sidewalk can look into our yard. We asked a landscaper to plant some photinias along the wall for privacy and instead of the full bushes we expected he gave us treed plants. He argued that the bushy top would provide privacy that we didn't need below where there are no branches. We expected the tops of the plants would continue to grow up and out but instead the only growth has been along the trunk where branches are starting to form. My wife says that to promote growth on top I should cut off these new branches but I am skeptical. I think that the only way the plants will grow up and out on top is to let the plant become the bush it clearly wants to become and that eventually, once it fills in below, it will grow up and out on top. What do you think?
In this case, if you want them to grow out on top, you will want to cut off all of the growth near the bottom. Take care when doing this though, as you only want to cut off about ten percent at one time... then wait a day or two and do it again.

My Photinia plants are showings signs of fungus! Can you recomend a good fungucide that I may use to curtail or cure the problem before they die altogether?
We don't recommend brands. Check with your local garden center.

Hi. We have purchased some photinia red robin pleached trees. Will the stems /trunks grow taller?
This depends on how tall they are now, and their age. Can you include a photo? This can help me to determine their age, and if they will grow anymore.
When would be the best time to plant a photinia bush as a border? Is the North Carolina beach area (not directly on the beach) a good place to plant them?
I see no issue with planting in this location. You will have the best success in spring time, but they can survive an early fall transplant as well. Make sure to keep them pruned, as they are susceptible to disease if they are left overgrown.
