Lovely shrub Photinia frasseri x "Red Robin" ! Notoriously difficult to propagate here - but in natural form grows like Billio in Australasia. This, in my opinion is an extremely valuable plant in many ways. Turning it into a "standard" - in my opinion is a bit daft. If it is planted as an ordinary bushy shrub, and pruned regularly - as soon as the new red shoots go """all green and ordinary"""" give it a haircut. This winter I`ve cut my photinia hedge really hard. I grew it from my own hardwood cuttings, and decided that it should be kept at a height that could be appreciated from an eye view.
Red Dahlia....your dad had the right idea ! Gardening is usually more about - what you take out - rather than what you put in.
We so often forget that nature takes her course ! What appears to be a problem when the weather is adverse is just our lovely living plants taking care of themselves.
When we have `orrid weather - chill out and wait. Most probs get sorted as soon as Spring gets going.
Photinia is prone to its own version of Rose Black Spot, and should be treated in the same way. Remove affected leaves ( it may look very bare for a while but will recover) and pick up any fallen leaves. Spray new growth with a fungicide like Systhane.
It spreads through a photinia by means of raindrops landing on an affected leaf and splashing onto other leaves.
My photinia recently has lost lots of leaves - post sever winds and salt from sea spray. Some new leaves curly after a short time. Should i prune back to healthy shoots.? New growth seem ok? Confused.. Had a beautiful bushy hedge.. Can i rescue it?
Now its sparce and needs something.. Help please.
I know this thread is a bit old now, but was interested by what Verdun was saying about photinias being fussy and disease-prone.
I have a still very young and small (1.5ft, plants last year) Pink Marble, which was literally massacred by a pest in Spring - most of the lovely, tender pink leaves were eaten in a matter of days, in spite of attempts on my part to protect it. I tried using garlic spray to deter pests, as I don't like using chemicals, and although this works brilliantly on aphids etc, I suspect pests like caterpillars etc don't mind it.
Has anyone had the same experience or know what could have eaten it so?
I never saw what it was doing the damage, but am determined not to let the little b****rs do the same thing again this year - it really decimated the poor plant...
I grow,this variety too.
I wonder if vine weevils were the culprit.
I am determined to keep my Pink Marble compact so I pruned back quite hard in its first,year and since.
Just re read,your post and now think caterpillars or snails were the nibblers. Weevils tend to eat notches and dont "decimate" leaves like that.....in my experience anyway. tiny snails in late summer can wreak havoc but caterpillars were a maor menace last year on a wide range of plants.
I would use nematodes Jess in the spring assuming snail damage
Yes, I'd initially thought vine weevils too 9we've been plagued the past 2 years and I've used nematodes), but as you said, the leaves were completely stripped bare, rather than having notches nibbled out of them.
I had slug pellets down for snails and used nematodes for slugs.
So by process of elimination, could it be caterpillars?
Wonder if there are nematodes for them too...my garden will be awash with about 3 different kinds by Spring, at this rate!
Hello Jess, yes there are nematodes for caterpillars.
Just be vigilant from,the start this year. Torchlight visits in the spring will confirm snails. Better than pellets.
You're right - just don't always have much time! But I try to use them only around a few more sensitive plants. Also have some resident frogs though, so would like to try eliminating all poisons, as I'm worried they could be harmed by pellets.
Nematodes for caterpillars it is then! Do you happen to know when they would be at their most active Verdun? It certainly looked like caterpillars could be the culprits, rather than snails, just because of the speed at which the leaf-stripping happened.
Spring would be best I think. Most other nematodes are used when it's warmer.
Good luck jess
Thanks Verdun you're a font of knowledge, as ever.
