It has been a cool and moist spring . Can I cut my Photinia down to 12 inches and spray with fungicide? I know that I have to rake up all the surrounding leaves and get rid of any branches and diseased parts. Thank you.
You can cut these down to about 6 inches for restorative pruning. This article will give you more information on how and when to do this:
Sent the pic of this plant in m garden.
It appears that it could be a variegated Photinia!
Here is an article for more information:
Hi. We have a Photinia that is more like a tree than a shrub. It has grown to about 18ft at its highest point with thick bare branches at the bottom. I have included a couple of photos to hopefully help with your advice. Our question is how hard can we prune this 'tree'? Can we be quite ruthless with it as at the moment it is a lovely tree but unmanageable. Many thanks.
Here's an article with all kinds of tips about how to prune -- please read them carefully so that your pruning doesn't introduce problems for the plant.
h red leaves but the 4th does not have a lot of new growth but lots of flower buds. What could cause the lack of new red leafed ne w growth. All have been treated the same way (watering/feed)? I have had to have the nursery replace one tree and that has done very well. The tree in question is not in the same state as the one I replaced. The subject Red Robin is quite close to a beech hedge compared with the others. This last winter 2019 was very wet!
It's possible the photinia is competing for nutrients with the beech hedge, or it is getting more rain runoff than the others. From the photo it looks like it's lower than the others but I can't really tell if there is an incline or not. Photinia doesn't tolerate waterlogged soils so I would check for that. Is it getting more shade than the others? That could cause leaf loss. Also check the leaves for spots (Photinia leaf spot).
Hoping that you maybe able to help. We have an extensive hedge of Photinia Robusta, which is doing well with a lot of vigorous growth. However the hedge is protruding over a footpath and needs to be extensively cut back. To do so we would have to cut 6-9 inches from face of the plant, exposing perhaps branches and no foliage. Question is would the foliage regrow over a period? Would appreciate your advise.
Yes, you can certainly hard-prune photinia, and it does leave a gaping hole. Here's an article that will help you learn how to rejuvenate it after pruning, and another about the pruning:
I bought a little red Robin lollipop tree about 18 months ago,the leaves became pitted, I followed advice sought to reply which I did, it seemed to do the trick, whatever it is it's back again but worse, pitted, dark and blotchy leaves and leaves dropping off. I have been reading up about fungus bit can't say for sure. Can you advise/diagnose please, I need to treat whatever is wrong with it.
It sounds like photinia leaf spot. It can come back each year. You have to diligently pick up and discard the dropped leaves. Here is more:
I have attached a leaf off my tree is it diseased? What can I do regarding my tree?
I can't tell from the photo but here are some common problems with photinia:
