Photinia "Red Robin" - need advice!
Hi
Last summer, I planted four Photinia "Red Robin" shrubs in my front yard because I loved the colour of their leaves and thought they would make an attractive property divide. They have now almost doubled in size but when I took a close look at them recently I noticed that they are absolutely covered in some kind of leaf spot. I am not a knowledgeable gardener, but I have read online that Photinia appear to be prone to leaf spot. I would like to save the plants but am not sure what to do. Any advice would be gratefully received. Many thanks - Debbie Virginia, USA |

It's a virus in the soil and I know of no true treatment. Second, it will certainly not do well if you try to keep it as a hedge. These plants want to be 12 feet tall and wide. You put them into unimaginable stress keeping them in a hedge. In Texas, they are way overused, and over pruned and there is a major decline with that plant, and many, if not all responsible garden centers no longer sell it. I advise you remove them while you still can and put something else there. |

Photinia "Red Robin" - need advice!
Hi - thanks for your reply!
I had a feeling someone would tell me to "bite the bullet", so I'm not exactly surprised by your advice to replace them (I guess I was just holding out hope that there was something I could do, because I love their leaves). Anyway, given the area that I live in (Charlottesville, VA) are there any evergreen shrubs that you could recommend me using as a property divide that would be more disease resistant - I don't want a traditional clipped hedge, I like plants that are allowed to grow in their natural shape and that require only a small amount of clipping to keep them from getting straggly. Something that had some colour/flowers would be nice. Also, do I need to treat the soil with anything before I replant new shrubs where the Photinias have been?

Check out chindo viburnums. We replaced our diseased photinas with them and
have been quite pleased. We're in NC, Zone 7/8. |

Any advice would be gratefully received. Many thanks - Debbie Virginia, USA Since you have to take a close look, yours aren't as bad as mine were and may have a chance. I had to rip mine out because the spot progressed to the point of no return. In my research about the disease I learned a few things. 1. Keep underneath the bush WELL raked. The disease is spread partly by spot-stricken leaves on the ground. The fallen leaves get splashed by water and send the spores upward to contaminate more leaves. Dispose of the leaves, do not compost or burn. 2. Use immunox anti-fungal in a spray once every 7-21 days. I'd suggest an Ortho dial-a-spray that is kept full of the stuff. Spray often. Soak the plants with the stuff when you spray. The Ortho helps you do this quickly. 3. Although more suceptible, new growth is your friend. You basically need to grow to reduce the proportional amount of the disease. Keep spraying and the new leaves will get the disease less. If they make it to green from red without a spot, they will likely stay that way. 4. As such, you need to make your soil friendly to growth. Try texas greensand for iron. I've heard that corn meal helps against the disease (Take a look at www.dirtdoctor.com for the "Sick tree treatment" 5. Don't cut them back to much. Part of the reason mine failed was that they were kept as a short hedge. Photinia want to grow. 6. If all else fails, go to a local "mom and pop" nursury, not to the BORG (Big Orange Retail Giant - Home Depot). Bring pictures of the location. Know where North is and when and how much sun the location gets. Ask them to recommend a suitable replacement. I went with dwarf holly and sage. |

Any advice would be gratefully received. Photinas are a bad choice for a hedge unless you're up to almost constant pruning. Another poster says they grow to 12' -- more like 20 to 25'. As for the leaf-spot, check with your local extension agent to ID the problem. Here's a site with pictures and info on Entomosporium maculatum: http://www.ces.ncsu.edu/depts/pp/not...11/odin011.htm |

There are varieties of nandina that grow lower and more densely than the
standard kind. All have reddish leaves at times of the year, and interesting form, and they don't outgrow their space. However, they are not as dense as some people like hedges to be. I think they might be hardy in Charlottesville. "Debbie" wrote in message ...

Photinia "Red Robin" - need advice!
Debbie,
From what I've been reading about photinias, I get the message to forget them. I moved to Virignia 3 years ago and have about 12 of them outside my fence next to the sidewalk. They were a wonderful source of privacy until last year (2003). They leafed out like normal but then dropped about 80% of the leaves due to leaf spot. I'm getting new growth this year but am taking a wait and see attitude. I agree with you that they are pretty (especially when in flower) but I'm sure there are other alternatives. I'm considering camellias. In any event, I'm not looking forward to removing my old shrubs. They are probably 10+ years old so quite established. Good luck with your shrubs.
