Phytophthora destroys Yew trees in Surrey

/in , /by

Phytophthora destroys Yew trees in Surrey: Arboriculturists and gardeners alike will be familiar with the devastating effects that Phytophthora causes.

There are several hundred organisms of the Phytophthora species of oomycetes, commonly known as water moulds, and after honey fungus, they are the most destructive cause of root rot and stem base decay in trees and shrubs. They don’t stop there. Member species cause enormous problems for crops, bedding plants, pot plants, herbaceous perennials, and all types of woody plants. Above-ground symptoms include wilting and branch dieback, but these are often not apparent until the root decay is well and truly advanced. It may also be there are other factors at work below ground. Examination of roots might show a poor root system, but Phytophthora are microscopic, so there will be no evidence the organisms are the cause. Laboratory examination may be needed to decide if it is Phytophthora root rot or waterlogging, with which it is usually associated. Either way, improving drainage greatly reduces the chances and risk of the disease.

Phytophthora destroys Yew trees in Surrey

Such was the case at an extensive property in Farnham, Surrey. The owner had planted between 150 and 200 new Yew trees only to lose them to Phytophthora. It was decided to replace them, but the spores remain living in the soil. One solution is to destroy affected plants and replace the root run with fresh topsoil. The problem is, the Phytophthora may remain at depth. The solution in the Farnham garden was provided by Terrain Aeration with a combination of their Terralift deep aeration system and the owner’s treatment with a liquid product when rain was imminent. While the product does not kill the Phytophthora, it stops it from spreading. The Terralift uses a probe to reach a one-metre depth where it releases compressed air which fractures and fissures the soil in interlinked stages. The resulting aeration allows water and air to reach the roots and the water to drain, so no waterlogging. If the liquid product was watered over the top of the roots, there would be a lot of wasted run-off. Fracturing down at one-metre depth, creating fissures that allow the liquid to be washed in by the rain, and to reach through the root areas, is an effective combination.

Aspen is the answer says GT Trees

/in , /by

Aspen is the answer says GT Trees: Cleaner, greener and lower maintenance costs. Those were the main reasons Greg Tucker of GT Trees made the switch to Aspen Fuel and, five years on, he’s still shouting about these benefits and many others he’s found using the Alkylate fuel in his independent gardening and landscaping business.

In an era when many professionals may feel the pressure to invest in electric tools, Greg cites how he and his customers value that Aspen improves conditions for people and the planet while reducing the amount of functional equipment resigned to the shed or scrapyard.

Greg has worked within the arb sector for 18 years, recently changing direction towards more artistic projects – hedge work, topiary, shrubs and small tree reduction. For this, he relies on the performance of his fleet of hand tools – mostly powered by Aspen 2-stroke Alkylate petrol. “My journey into using Aspen is pretty common… I’d heard of it, gave it a try and I’ve been using it ever since” he explains. “My maintenance costs have reduced, and from the operator perspective, the headaches, congestion and other health implications typically associated with being in close proximity to petrol-powered equipment has been all-but eliminated.”

“Like most, I have explored electric tools but found they just didn’t cut it – literally! Battery life was not practical and, ultimately, the kit we already have does exactly the job we need it to. Through using Aspen, we can do our bit to be kinder to ourselves and the environment, and not be throwing away serviceable equipment.”

Aspen 2 is a pre-mixed 2-stroke Alkylate petrol, free from ethanol, benzene and many of the other hazardous hydrocarbons typically found in unleaded from the pump. This means that Aspen burns cleaner, reducing harmful emissions and providing reliable engine performance.

“We use roughly 25 litres a month, which we order through our local distributor, and find that the increase in the price is offset by the reduction in expensive repair bills we’ve had.” Greg continues, “You know what you’re going to get – you’re not going to get halfway through a job and run out of juice! Customers also recognise the red Aspen cans and are completely sold as soon as I reel off all of the benefits it has. I can’t recommend it enough!”

ACW Trees tackle rising fuel costs

/in , /by

ACW Trees tackle rising fuel costs: To keep up with new technologies and latest industry developments, family-run ACW Trees in the West Midlands opt to upgrade their woodchipper fleet every three years – their most recent review seeing a GreenMech ArbTrak 200 swapped for TWO machines from the GreenMech EVO series!

Owner Adam Willington and his team now have the versatility of a road-tow EVO 165D and track-based EVO 205DT at their disposal and have found the pair to excel in power, maneuverability and fuel efficiency.

Following time in the Parachute Regiment, Adam moved into a career in forestry before establishing ACW Trees eight years ago – now undertaking a wide variety of jobs with both domestic and commercial clients with the assistance of his team of two. “Technology in the arb market is changing all the time so when it’s time to upgrade, I’ll go out to the market and research all of the options. What’s noticeable, having looked at the main three manufacturers, is how the build quality of GreenMech’s EVO range now supersedes the competition and, performance-wise, is leading the way” says Adam.

The team opted for the EVO 165D, and larger 8” capacity EVO 205DT for optimal flexibility and safe traversal of sloped or uneven ground. Delivering more aggressive torque, bite and throughput, Adam also opted for the optional folding chute on both new machines, delivered in October 2022, which he adds is “ideal for moving the chippers around and safely storing them in the yard or other small, restricted access spaces.”

“Like most small businesses, we’re conscious of costs and fuel is a big issue currently. One thing we really liked about the EVO 205DT is the ‘economy mode’ where you set the engine RPM to automatically reduce after a given interval when no timber is being processed which has massively improved our fuel economy.” He continues, “In addition, we’ve found the powerful throw on both machines helps to pack the chips more tightly in the back of the truck meaning we’re making fewer trips to empty, lowering fuel consumption even further.”

Adam certainly hasn’t gone easy on the chippers in the nine months since taking delivery, putting them both thoroughly through their paces on all types of terrain. “We’ve had no trouble in getting the EVO’s exactly where we need them – be that up and down steep slopes, wooded or boggy areas and even tracking the 205DT through little streams! The robustness and reliability they’ve given us has been brilliant, and like always, backed up with excellent service and technical support from the GreenMech team.”

Terrain deep penetration aeration for trees

/in , , /by

Terrain deep penetration aeration for trees: We tend to take trees for granted, in our parks, estates and gardens, as a natural part of the landscape.

All too often they are subjected to stress as a result of a number of factors such as nutrient shortages in the soil, surface compaction due to foot traffic and waterlogging where water drains off hard surface pathways. Armed with a number of solutions, Terrain Aeration have been treating trees in all types of situation for over twenty-five years, from back gardens to large estates right through to Royal Parks.

The Terrain Aeration Terralift machines comprise a probe which reaches one metre depth, deeper than the roots of trees (other than the major tap roots which grow straight down).  Breaking up the soil around the roots, and beyond, means that excess water will drain away from the roots to help stop anaerobic conditions and rotting of the root system.  The probe is then used to inject dried seaweed which helps keep the fissures open and backfilling the probe holes with aggregate provides a semi permanent aeration/ventilation shaft.  Terrain Aeration aerate around the roots using two-metre spacings – on most occasions one-metre inside and one-metre outside the canopy drip line, as this is where the growing roots lie.  Decompacting around the roots and injecting air into the soil increases the percentage of uptake of oxygen into the root system.

In one particular situation it was found there was a magnesium deficiency coupled with low overall soil fertility around trees in a park. This was determined using new technology to measure light transmission through the leaves on the trees to gain a reading of chlorophyll levels. The likely cause of the problem was that leaf litter is always removed and had been for a century, taking with it the natural nutrients from decaying leaves. There was also severe compaction of the surface around the tree. A tree feed mix containing slow release general nutrients and magnesium was injected, using the Terralift’s ability to inject granular material via its seaweed carrier, forcing it upwards into the root zone of the trees. This also avoids losing the nutrients to the grass which would occur with surface treatment. Two Terralift machines were used to carry out the process.

There are some products in the market place which advertise to be of help for trees with Phytophthora. There is a product which is applied around the tree roots via a watering can.  If the tree roots have been aerated by the Terralift machine, the product has a far better chance of reaching affected roots due to the soil being decompacted.  There are machines that will go shallower, but this does not have such an effective treatment as you would still need to get excess water away from laying stagnant around the roots. Terrain Aeration also recommend that root samples from good and affected trees, as well as tip samples be sent for full analysis from the Forestry Commission or any other Arboricultural advisor.  The samples should be labelled as well as being placed in separate plastic bags.  Photos of the location of the trees would also help, just in case there is a huge wall on three sides of the tree or something which could affect its well being. It’s best to give a complete “story” surrounding the tree. For more details on deep penetration aeration treatment for trees, sports pitches, golf courses and gardens:

£2.6m Pledged For Trees And Green Spaces

/in , /by

£2.6m Pledged For Trees And Green Spaces: Trees and green spaces will feature in a number of projects which will receive an investment £2.6 million from Natural Resources Wales (NRW) over the next two years in order to improve Wales’ environment.

The projects were selected under the four themes of reducing the risk from environmental hazards; improving habitat management, biodiversity and connectivity; improving access to the outdoors; and using the environment to support the economy and develop skills.


Among the successful bids are:

  • Roots and Water, a project by Severn Rivers Trust with the Woodland Trust to raise awareness of the importance of tree planting for multiple benefits such improving air quality, reducing flood risk and creating habitats for wildlife in the upper Severn area of mid-Wales. They will work with landowners, volunteers and community groups to plant native hedgerow trees and propagate the black poplar tree.
  • Shared Spaces, a project run by Hay-on-Wye Town Council to create green corridors in and around the town to link wildlife habitats and so tackle the decline in biodiversity, with wooden sculptures and interpretation boards on the route’s wildlife.
  • Nature for Health, a joint venture by Denbighshire Countryside Services and the Denbighshire County Council Housing Department, which will use environmental social prescribing and GP referrals to encourage communities to access and enjoy their local green spaces.
  • Gower Hedgerow Hub, to address the over 800km of hedgerows on the Gower peninsula recorded as in poor condition, by engaging and training landowners and volunteers to create an intact, continuous hedgerow to act as a wildlife corridor.

Chair of NRW’s Strategic Funding Board Rhian Jardine said: “We need to make the most of our resources and we must find new, innovative ways to deliver the best outcomes for the environment, for wildlife and for people.

“Our commissioning approach, where we set out the challenges for specific areas of Wales, generated interest across all sectors, and we have several partners who will receive funding for the first time.”
