What he said but underground guying is even better.

Cryptomeria japonica - I think.

To add to what Jules said: Cameraria - stem injections are also now available to treat the issue which may be more practical. As Jules said, spraying large trees is difficult although I think they do it in the USA. Guignardia - Not as serious as the other two issues and can be mitigated by removing leaf litter and burning during the winter. The spores over winter in the fallen leaves. Pseudomonas - This one is a bit more interesting and as Jules said more difficult to treat. Chap called Glynn Percival has had some success in treating the disease with decompaction and Potassium Phosphite fertilizer. The decompaction can be employed proactively I would think as a preventative measure also. The fertilizer approach is said to boost the trees immune system so it can fight the disease itself. Glynn refers to this as a systemic induced response. Cheers

Hi Len It depends on the type of sand, sharp sand should be fine but builders sand has a high sodium content which can be damaging to the trees - i.e. the sodium ion is toxic to trees. Also, raising soil levels over trees by 6 inches is probably a bad idea irrespective of the type of sand as it can limit gaseous diffusion between the soil and atmosphere and cause compaction further limiting gaseous diffusion. Hope this helps

Atomic Jam - blast from the past. Don't forget Sundisential and God's Kitchen - late 90's - early 00's.

Quite the opposite. Never seen a fight at one and the predatory type are generally not welcome.

Not a bad shout, or maybe Katsura?

Tree ferns if you have shade and a large wallet. Always look good in pots.

Its a difficult one for consultants that is. They rely on repeat works from these people. I think money should be made available for TOs to monitor properly. I went to the ICF - TPBE3 conference this week at Birmingham University. There was a Canadian Tree Officer there saying that the Council he works for has a $12m annual tree budget. Its a big area but even so that is a lot of money.

Tree retention conditions usually last for five years after the site is signed off.

The picture is more likely to be a graft union where the root stock is more vigorous than the scion, hence the difference in growth. Not sure about the insurance thing as I have been off the tools for about 12 years. There is an NPTC cert for using stump grinders though, maybe that is what he is talking about. There are folk on here better positioned to answer that though than me.

It should be ok as long as he is not working in the district. It will need to be signed off by the head of service though. I've done it at two different authorities.

Yeah that is correct, that is what I meant. sorry if it was misleading.

If you don't go into the cites affected then it shouldn't be a problem. I do unfortunately. You can still go diesel from what I have read but they have to be EU6 compliant engines. This is anything built and registered after 01.09.2015 I believe. i.e. expensive.

If you are going to be working in or around certain cities then I would wait until the toxin tax is released before buying anything that runs in diesel.

If it is Phytophthora then I would think it is more likely to be P. citricola or P. cactorum. They are documented on lime. You can get exudates from Honey Fungus also, just a thought. Cheers

I would imagine they did but the developers have ignored it. I saw one site where they stored the materials inside the tree protection barriers so it didn't get stolen. That's what the site manager said when I asked, I was there to monitor!!! Its not uncommon.

Out of interest folks, is there much interest in this type of course from tree surgeons. I have a teaching qualification on top of my arb stuff so I have been considering running some training courses. ISA would be a good starting point I think. Not at the moment but in a couple of years, don't have the time at present. Would be good to get a read on it. Any feedback would be appreciated. Cheers

Yeah no probs. Try this: Training I did my tech cert and L6 dip, plus a load of short courses with them and would highly recommend. There are quite a few ex and current tree life students on this site so I'm sure others would recommend also. Its not listed on the website yet as they are only just starting to run it this year. They have a mailing list which is how I got to hear about it. Speak to Keely on 0116 2606939 or [email protected] Cheers and good luck

Not wishing to step on Paul's toes but Tree life are also running the ISA as supported study now. I think its about 6 sessions. Just in case the OP wants to get going sooner rather than later. Cheers

I did it during 2002. I read the book twice and did the little tests at the end of each section. Then sat the exam and passed - it wasn't difficult. To put it into perspective though, I had passed NC arb in 98 so it was just re-capping really. May take you a bit longer but if you have done HNC previously it should be well within your capabilities. The value of the ISA Cert Arb really comes from completing the CEUs once you have passed. In my opinion anyway. Good luck Cheers

I would agree, I would go with Eastern due to the upturned needles.

I would take great pleasure in telling him he is an idiot. I've enforced old TPOs with misidentified trees. I've also had legal departments refuse to enforce TPOs which were spot on for other reasons. When you present these issues to the council legal department they will look at what are called mitigating and aggravating factors. Its what John was referring to when he mentioned using it as a defence, i.e. wrong tree on the schedule, I didn't know, Its not my fault - mitigating factor. But what if the tree officer had sent you an email saying that the tree on the schedule marked as a Norway maple is actually a sycamore and that it was just a minor mistake. That he advised that the tree was still protected and made reference to a site meeting where he advised you of the same. These would be aggravating factors. It would be a good idea to vary but I doubt you would get far with the defence of its not got the correct name on the schedule. Anyway, its not misidentified. Its down as a deciduous tree which it is, and I suspect they will modify on confirmation to include the species. I cant really see a problem with that. Cheers

I always include heads of terms for the AMS at the end of the AIA, the standard specifically says you should. Even if I don't think it needs one, I will make the point that not needed but if the council insists then the following issues shall be addressed.

Yes I agree but if the TO has any sense it will never come to that, they will modify the schedule on confirmation once they have had a chance to look at the tree in leaf. Mind you, its a bit of a shocker of they can't identify a Walnut during the winter!!!
