Peach Leaf Curl

...

As a by the way…. just because its called peach leaf curl, it doesn’t mean it only affects peach trees. It will affect most Prunus related species.

Anyhow, I don’t like this one at all. It simply looks so ugly…. caused by the fungus Taphrina deformans [the second part of the name says it all…], it is spread by rain and wind where it will hibernate in stem cracks, scars or wounds and there is literally damn all one can do about it.

The leaves become distorted and bubble up like big ugly red blisters. En mass, it is pretty ugly to look at and I kind of feel sorry for the plant…. especially when all of the leaves fall off.

Whilst chemical control via any sort of fungicide will do the job… in my own garden I prefer to let nature do what it must and maybe from a biological control point of way I may get involved…. But the leaves do grow back and hopefully the plant will come good. But isn’t that what gardening is all about…

Autumn Colour…

Can you imagine if every house in Ireland planted just one tree, how beautiful would this country look….

...

I really do love this time of year.

Last week I was walking down Griffith Avenue and being honest it almost brought me back to my childhood days of not that long ago…
I used to love the leaves on the ground and absolutely hated it when people swept them all up and made the place look tidy. When I saw the piles I was one of those ‘little terrors’ who kicked them all over the place and most likely got an ear clipping for it 😆
Sidetracking slightly, Jane Powers who does the Irish Times garden column, this weekend wrote about the beauty of autumn colour. A great read. Bulaidh bós Jane.
You see, landscaping, well more the trends [?] took a turn for the worst in my opinion over the last few years. Trees, if not all then most definitely the larger members of the family were not allowed. They became surplus to requirement. Some, quarantined them in the high maintenance category. So much so that I find it hard to find [for example] a ‘conker tree’ in North County Dublin…. which is why I went to Griffith Avenue 😉 [I also visited my older brother who lives just off and had some home made chocalate pie and real coffee….]
But its not until, maybe, one sees a tree in its finest splendour through a season that one thinks…. well maybe I would like one of those. And with that in mind tree planting season is almost upon us…. Now is the time to decide that you would like.
Can you imagine if every house in Ireland planted just one tree how beautiful this country would look. If you don’t plant one…buy one for somebody you like to brighten their day up… then go and admire their one… or rake some leaves up and allow the kids to kick them all over the place…. 😆
As a by the way…. autumn colour is brought about by a build up in sugars from warm temperatures during the day and then a cold night where the sugars are held in the leaf.

powdery mildew

powdery-mildew

powdery mildew

I noticed this white almost chalk like residue on my corkscew hazel the other day.

It is powdery mildew.

Caused by a variety of fungi  including Oidium, Uncinula & Sphaerotheca; the powdery chalk like residue sits on and clings to the top of the leaf.

It’s sister downey mildew clings to the underside of the leaf and is damp and fluffy to feel… So as not to confuse the 2, remember: powders could not sit on an underside [as simple as that sounds – to the non horticultural C.S.I. diagnostics team it is very important 😉 ].

Back to it…. One must remember that this is a fungal problem. And spores are spread by wind, rain or even plants rubbing together. Powdery mildew likes a dry site and fungi usually grow in areas where it has little chance of being disturbed. So, whilst it can be sprayed/ treated chemically… this will solve the immediate problem but, the chances are the disease will return as the conditions/ environment have not changed. My methodology is to remove all of the diseased material; then wait if possible ’til the off season and move the plant to less enclosed spot.

The reality is, one should also remember that this is not a bacterial disease of the plant so whilst photosynthesis is affected; and therefore fruit/ seed production – the disease is not as such detrimental to the plant.

Chemcal treatment is usually done via the use of a translocated/ systemic insecticide and fungicide mixed as most insects are disease vectors. Make sure [please] you have a seperate applicated sprayer to the one used for herbicide 😉 That said, I prefer working with nature where possible and would always first recommend the biological control first.

While I’m here… if you are spraying it can leave a white residue…. don’t confuse the two 🙂
