Bridgnorth Oak tree in need of special care

RAW Tree Care were chosen from a number of local contractors to work upon an oak tree in Bridgnorth which needed a bit of TLC. During recent construction work the ground around the tree had be heavily disturbed and roots would have been severed. There is an extensive cavity in one limb which has continued to withstand high winds and another limb had been lost some time ago. The branch tips were also showing signs of dieback and there was strong epicormic growth (new branches sprouting) in the lower canopy.

Before and after a 30% reduction badly needed to reduce weight whilst maintaining strong growth.

Because of the ground disturbance and the cavity it was decided to remove 30% of the canopy to reduce both weight and wind loading across the whole tree. Even though the cavity is structurally sound at present, by lowering the stresses upon it we are able to help prevent premature limb loss in the future.

The reduction was conducted carefully, cutting out the weaker limbs whilst maintaing the stronger growth and taking care not to damage the lower epicormic growth. The tree should now go on to live long past any of us alive today.

The Soul of Trees

Have you ever seen a knot in a plank of wood and wondered where it came from and how it fitted in the tree when it was alive? Ok, well maybe it was just me as a child, wondering what a knot was and how it ended up in the peice of wood i was holding.

Know i know that a branch goes deep into the parent branch/trunk creating a strong a branch root to support the weight of the branch.

As a child i would wonder what it would be like to carve away the outer layers of a tree to leave the branch root intact, tracing the (often annoying knot) back as far as i could. Luckily Italian artist Giuseppe Penone has gone to the trouble for me.

Giuseppe Penone’s work, The Hidden Life Within, reveals the sapplings hidden within the older trees they had become. Some of the peice look very intricate to carve while others (such as the tree of 12 meters) look just like trees which have had their bark removed, that is untill you notice the base.

Conifer Hedge Trimming in Wolverhampton

Remember the hot weather a month or so ago? Well it was durning that time we were contacted about a large conifer hedge at a Wolverhampton home near Tetenhall, Newbridge to be precise.

Most of the garden under the trees was taken up by a large fish pond and extracting the waste up the steps and through the garage would have been hard slow work. Luckily to the right of the garden there was an industrial unit – Wolves Hire . They were happy for us to use the area in front of the unit as a drop zone for the branches we were removing.

All of the branches had to be passed over to the right

The ones on the left were easy to work on and one climber worked to make enough room to pass the ones further away through the gap made. When we were to far to pass the branches safely to the ground a second climber was used to pass the branches along the hedge  before passing them to the waiting ground staff.

We worked from right to left, passing the removed branches over to the right hand side of the picture

The job went smoothly and the customer was left with more light but without loosing any privacy and, despite the threatening skys, we did not get wet.

If you have a tree which needs attention please do get in touch

 

How not to be a tree surgeon (and how not to prune a tree)

As a tree surgeon, driving around anywhere can be an annoying thing. We tend to look at the trees and notice recent work and bad work stands out like a sore thumb. It equally annoying to see people offering a whole range of services including tree work. Trees are complex biomechanical structures and anyone who has spent years on the job or thousands of pounds going to college is not going to suddenly offer fencing or landscaping service. Trees are a specialist field and I would not recommend using any fencing/building/landscaping contractor who claims to offer tree surgery. Sorry, rant over.

Below are a few pictures from one site in the West Midlands who decided to get a landscaper in to do some tree work. I am sure there are some good landscapers out there who are capable of tree surgery, but i would only recommend using a landscaping company with a dedicated arboriculture division

The first two pictures, of the same tree, look pretty bad. The most obvious problem is the large tears all over the tree. These look unsightly and will induce rot and decay into the tree as the would is much larger than it should be. Pruning cuts should be flat (i.e. 90 degrees to angle of the branch) to minimise the surface area of the wound and try to prevent decay, parasites etc getting into the wound. The tree is able to callus over a correctly finished cut but will never be able to recover from these wounds.

But the pegs (the bit of branch which has been left behind) are just as bad. When cut correctly the tree is able to seal the wound, limiting decay. When a peg is left the tree is unable to seal the wound.The peg remains and rots away bringing parasites, pests and disease to the wound. A flush cut (not shown here) is just as bad as it creates a large wound and severs the vascular tissue of the parent branch, again inducing decay and preventing the tree from forming a callus to seal the wound.

The second tree has the same bad cuts as the tree above but has been left in a dangerous state. Trees should balance, they can adapt over a long period of time to support a crown which is weighted heavily in one direction, but if part of a tree is removed the tree can be come unbalanced and unstable. The centre of this tree has been removed leaving it heavily weighted towards the fence and the neighbouring house. It is heavily unbalanced, the wounds will decay and if the tree fails it is only going one way. Also because the centre has been removed any future tree surgery is made more difficult as the natural anchor points, for a tree surgeons rope, have been removed.

This is why it is important to ask for proof of insurance. Sure the landscaper didn’t break any fence panels on the day but what happens if the tree fails, because of his bad work, and falls on a house after he has left?

Work like this is truly shocking and I have spoken to the owner of the property who is trying to get the work rectified.
