arbutus problem

arbutus problem

I have I think a variety of Arbutus. it seems to be suffering in some way. im wondering if you can have a look at the pictures and see what you think, and if i can treat it. 081020111, newtown, Co Tipperary Posted: 20/05/2014


The tree or large bush is Crinodendron, or Chinese lantern tree, not arbutus. It has red lantern-type flowers.

It looks to be suffering from wind damage, leaves withering. This probably occurred during the February storms and it likes reasonable shelter.

There is not much to do. The grass in a 2-metre diameter might be controlled with weed fabric and mulch placed on top to depth of 8cms to give the roots a boost.



Black spot on leaves of Photinia Red Robin

My son in law has a Red Robin tree in the garden of his recently bought house in Swords, so we can't tell how old it is. It is about 8 ft tall. He asked me about it today as it has black spot on the green leaves and the new red leaves are shrivelled and crispy, but not falling off. The spots are black and not red which makes me think it is not the disease that this tree can get. Could it be from the recent cold winds or frost? Would appreciate your advise.

Photinia 'Red Robin' can suffer foliage damage in an exposed spot on both young and older leaves. Also there has been some damage done in recent years by leaf spot disease, about which not much can be done.

Give it a feed of tree and shrub fertiliser and see if it comes on. If not, it might need to be removed as it is not happy in the location. 



Sick Magnolia wilsonii

My Magnolia wilsonii is sick, few leaves, dying branches, damaged buds, possibly due to cold weather after early good weather. What should I do to try to rescue this favourite of mine? Noelfitz, Blackrock, Co Dublin Posted: 25/04/2012


This is very likely to be due to harsh winds in recent days. Magnolia foliage is very easily damaged by wind, usually due to branches hitting each other as they move in the wind.

Although it looks bad when it happens, the expansion of leaves will largely hide it in a while.

  old hedge needs replacing

old hedge needs replacing

i have just cut down a very old ditch that has been there for i'm sure 30 odd years, i want to put in a hedge/ shelter belt as i'm putting up a polytunnel 48 foot long and 20 foot widethe garden is south facing and gets sun all day but i get severe frost and up to 90 plus mile an hour winds whats the best hedge to put in i'm thinking of laural and evergreen holly what do you suggest ? milliemouse1234, templemore, Co Tipperary Posted: 15/01/2012


The great thing about an old traditional hedge/ditch is that it is mostly composed of species that will re-sprout and re-establish, such as ash, hawthorn, furze, blackthon and holly.

You should allow these established plants to re-grow, which they will do at several times the rate of growth of young plants, and simply plant any gaps with hawthorn and holly.

Young plants will find it very difficult to compete with the large roots of the old trees and will need watering.


Deciduous trees withering early

My question is a very general one and I would imagine a lot of perople have noticed this and that is that the leaves of many deciduous trees are almost gone and we're still in July. Sycamores and horsechestnuts for example are all looking the worst for wear. Some have observed that the west side of many trees are faring the worst. Do you have any ideas/suggestions as to why we are seeing this? Dig_It_Man, Athenry, Co Galway Posted: 26/07/2011


This is purely weather-related.

In May there was a severe gale especially in the west ... an gaoth rua, the old people called it ... the red wind. It can from the west/ southwest. Leaves damaged then have been shed in some cases.

Also it was very dry in April and a soil moisture deficict at depth has not been replenished ... same reason the reservoirs are low. And trees react by reducing their leaf load.

Fatsia- large holes in leaves

I have a fatsia for several years but find that something always eats the leaves. I dont think it is slugs or snails. Have you any suggestions, Please Myrtle, Dublin , Co Dublin Posted: 06/07/2011


The photograph shows physical damage caused by wind, or some other agent.
