Some times we carry out work along the river, working off boats and using barges to remove the arisings.

I've sent them an email and I'm awaiting reply

I bet you would be

Most of our work occurs in and around Norwich. You will predominately be working in a team of two. However, larger contracts are tackled using two qualified grounds men from our landscaping/grounds maintenance division. The ideal candidate will have CS 30, 31 and 38, and a good work ethic as a minimum. CS 39, MEWP, first aid, and experience of water crafts would be an added bonus but is not essential. Work would commence on the 14th of March with a months probation. Salary will be dependent on age, experience and qualifications. If your interested please PM me your details along with your CV.

I'm thinking of selling our 140mm PTO Pezzolato as it just doesn't get used enough. It was built in November 1999 but has only done 237 hours. I just wanted guidance on the price I should be selling it for as it's not a well known make in the UK. I was thinking £2,500 to £3,000. Is this a fair price?

We use a 140mm PTO Pezzolato on our 33Hp John Deer 995. However we have also run it off our 22Hp John Deer 455. The stress control just kicks in more often. It's always useful to have a grab bucket for shifting timber and chip in the woods.

Loved the second vid. What was the music?

I find a long-reach hedge cutter works best

An extract from my dissertation: Although A. hippocastanum is the principal host of C. ohridella in Europe, many other Aesculus species are also susceptible. A. turbinata (Japanese Horse chestnut) is highly susceptible, and species from North America, such as A. californica (California Buckeye), A. flava, A. glabra (Ohio Buckeye), A. parviflora, A. pavia (Red Buckeye), and A. sylvatica (Painted Buckeye) are moderately susceptible (Freies et al., 2004). In contrast, other species from Asia, such as A. assamica (East Himalayan Horse chestnut), A. chinensis (Chinese Horse chestnut) and A. indica, are generally resistant (Straw and Tilbury, 2006). A. x carnea is highly resistant to C. ohridella, killing the larvae in the first or second instar (Freies et al., 2004). The majority of other Aesculus hybrids are derived from crosses between A. flava, A. glabra, A. pavia and A. sylvatica (Bean, 1970; Daniels, 1984; Huxley, 1999). Susceptibility to C. ohridella varies from moderately susceptible in A. x bushii to highly resistant in A. x neglecta (Straw and Tilbury, 2006). C. ohridella has also been reported to damage Acer platanoides (Norway maple) and Acer pseudoplatanus (Sycamore) (Gregor et al., 1998; Straw and Tilbury, 2006). This host range expansion is expected to increase further, threatening many other trees (CONROCAM, 2004).

No, I've just done my dissertation on it.

Fallen leaves can be removed and destroyed to prevent the pupae over-wintering. And a variety of chemical insecticides, including diflubenzuron, imidacloprid and abamectin, are effective in controlling the leaf miner and preventing leaf damage. Systemic insecticides are best applied as root drenches or injected into the stem cambium or soil. Alternatively, Allicin/Conquer injected into the stem cambium like a systemic insecticide is also proving to be successful.

Yes, the particularly weak horse chestnut branches become even more brittle and susceptible to sudden fracture and drop as the infected dead wood dries out.

There are no proven ways of treating the bacterium. However, ensuring the tree is healthy and vigorous will reduce susceptibility to the infection and facilitate recovery. As more than 80% of urban tree disorders are caused by problems below ground it's paramount to create a healthy environment for the tree's roots to thrive. The most common problems include nutrient deficiencies, drought and soil compaction. So anything to remedy these problems (decompaction/aeration of the rhizosphere, nutrient and mycorrhizae spore injection, aplication of organic mulch and restricting public access to the RPA) will improve the tree's chance of survival. Leaf miner infestation will also reduce the tree's photosynthetic performance, depleting starch reserves and reducing the tree's productivity and vigour. Thus also needs to be controlled. It's also worth looking into Allicin/Conquer if the budget allows.

The dead tissue on your leaf are the mines of the horse chestnut leaf miner larvae, while the shedding limbs in your local wood are most likely caused by horse chestnut bleeding canker.

No worries scottie

Beat me to it

The target area is high with many vehicles passing and parking beneath it on a daily occurrence

Sadly thats what I thought. But as it has a TPO wont I have to provide evidence that the decay is advanced enough to cause root failure?

Yeah, sounds about right, I think it started in the mid 80's. Before I was borne anyway. The interior side is where I started but soon progressed to the exterior side.

To those of you that helped me with my dissertation and others who are interested, please find attached a copy of my dissertation on the extent and severity of horse chestnut leaf miner and bleeding canker, and the success of management techniques used to mitigate these problems. The dissertation achieved a first class honours thanks to many peoples help. I hope you find it informative. If you have any questions please do not hesitate to contact me. Dissertation Final.pdf

What action would you take considering this healthy oaks location? I'm thinking of proposing a root investigation to establish the extent of the decay. Would you also suggest a picus scan? Thanks

Thanks Tony and Chris, thats what I thought. Chris it's the Hornbeam of fertility at Hatfield Forest in Essex.

Anyone?

This weeping lime I had a look at today has reverted. Should the top be cut out to encourage weeping re-growth, or will this just result in vigorous non-weeping re-growth and cause problems in future with decay and weakly attached branches?
