Common ProblemsContainer GrowingPropagationPruningRed Robin
A popular garden hedge , photinia is a shrub that has seen an increase in its use in British garden in recent year .
It features brilliant spring and summer colours , as young foliation and fresh leaves are a prominent chromaticity of redness .
Rightfully consider a low - alimony evergreen plant , photinia is susceptible to some problem and offspring that are exacerbated by incorrect get conditions .
They are also minimised by favourable grow conditions , and can on the whole be ward off in optimal conditions .
We partake 5 of the most common issues and problems you may come across with your photinia shrubs , outlining how each trouble can be avoided and regale .
1) Leaf Spot
A fungal disease , leaf point is in all probability the most annoying and continuing , though not the most serious , job that can strike Photinia .
The disease is well-off to recognise as it manifests as little red smear on leave .
The spots become heavy and blotchier , darken to maroon - purpleness , until eventually it starts shedding its pathologic leaves , and does so continually .
heating , humidity , and wetness promote the facing pages of the folio spot fungus , so by adjusting your photinia ’s growing conditions , you should be capable to forestall leaf spot from occurring in the first topographic point .
Appropriately - diluted solvent can also be applied as a foliar spray about every 10 day .
2) Fireblight
Fireblight is a bacterial disease and is likely the most dreaded affliction of photinias , and that is because there is no remedy usable to a hobbyist gardener .
Summer is usually when this disease raises its horrible headspring .
The symptoms of this disease are shoots and young leaves rapidly dry out out , browning , and dying as if they have been blighted or scorched by acute sun or flaming – hence the name .
In addition , cankers may appear on mature branches which may take off to ooze .
Again , you may go some way toward preventing fireblight in the first situation , but if you are too late , there are alas no commercial-grade chemical substance controls for this disease .
If you descry it in the initial stages , you have a combat chance if you chop-chop prune or lop all affected parts .
The caper here is to peel back barque from the trimmed branches to inspect whether you may see a reddish - brown discolouration .
If you do , cut the branch to a small level .
Alternatively , you could work it safe and hard cut the bush .
3) Powdery Mildew
Photinia bushes can also be affected by powdery mildew .
Powdery Mildew appear as a greyish - white powdery layer on the leaf .
It too is strongly linked to humidness , wet , and tint , so you should avert it by watering at the land degree .
Affected theatrical role need to be trimmed back .
4) Frost Damage
icing price is , in the primary , simply a pain in the neck .
A cold-blooded snatch or parky wind could bolt down go forth shoots and foliage , though mature branches and foliage will not be damaged .
The result is red ink of colour , heyday , or both .
5) Root Rot
Root Rot is a very serious complaint which can test dangerous for any plant .
Soil that stays soak , dense and fleshy , or drains ill can lead to antecedent rot .
A container - bind photinia can certainly be handle for root rot provided the character is not advanced .
The plant has to be pull up and the rotten lengths of the roots , as long as they are not extensive , necessitate to be snub aside and the plant must be re - potted in fresh soil .
Unfortunately , a great open - soil hedge that is afflicted with radical rot may be unmanageable to save .
