It’s possible you’ll not intend to prune your bushes your self.

However even in case you make use of a tree surgeon, there are key info you want to learn about tree upkeep.

This can aid you discover a good tree surgeon and get the perfect outcomes.

As a result of pruning bushes isn’t only a query of chopping them all the way down to the scale you need.

You may safely scale back the peak of some bushes, but it surely’s very tough to scale back their width.  And but it’s precisely the alternative with different bushes.

And in case you prune an excessive amount of off many bushes, they’ll usually reply by re-doubling their progress. You might find yourself with far more tree moderately than much less. This could occur in a short time. And the form isn’t more likely to look nearly as good.

Like most gardeners, I’ve a mixture of bushes in my backyard. Many have been planted by my predecessors. There are two evergreens, each of which have grown moderately too giant.

I even have quite a few deciduous bushes of various ages, shapes and elegance. So I engaged tree surgeons About Bushes to test all my bushes and scale back the scale of the bigger ones.

And I requested Wayne Elwell of About Bushes to elucidate what you want to know earlier than you prune your bushes.

(Disclosure: I engaged About Bushes on the regular industrial charge and solely invited Wayne for interview after that had been agreed. I believe it’s value explaining this, as generally there are reductions or free providers concerned when firms are featured on blogs and many others. However not on this case.)

When do you have to prune your bushes?

Autumn and winter are a great time to prune most bushes, as a result of they’re not rising. Some bushes, such because the prunus (cherry) household must be pruned in summer season.

You may lookup the perfect time to prune a selected form of tree on-line.

However most gardeners agree that there’s an ‘very best’ time to do work. After which there’s once you’ve bought time.

Autumn and winter are good times to prune trees.

How do you scale back the peak of a tall tree?

Wayne defined that this relies on the tree and the way it each grows.  Some bushes, equivalent to birches, don’t like being pruned closely in any respect.  ‘Birches don’t get better properly in case you prune into the center wooden,’ says Wayne. ‘So any pruning must be respectful.’

To scale back the peak of a birch, you’d must do some mild pruning throughout the crown.

Merely chopping alongside the highest of a tree to scale back its top isn’t at all times profitable. Many bushes will sprout vigorous new progress across the cuts. You might find yourself with a a lot denser tree which might solid deeper shade. And also you usually destroy its form.

‘A shopper is perhaps happy to see that we’ve pruned a tree again in order that it seems actually small,’ says Wayne. ‘however long run, you’re going to advertise extra progress, a thicker cover, extra leaves and bigger leaves.’

Nevertheless, you possibly can lower throughout the highest of some bushes to scale back the peak. About Bushes decreased the peak of my Lawson cypress and likewise my liquidambar by merely eradicating the highest few metres of progress.

Silver birches need careful pruning - don't cut too much off

Birch bushes want cautious pruning – don’t lower an excessive amount of off. About Bushes shortened some branches and thinned out the cover of the Himalayan birch on the left. They thinned the cover of the youthful Himalayan birch on the fitting. This can enable extra mild by way of each bushes.

One other view of the Himalayan birch, Prunus ‘Snow Goose’ and Liquidambar. They’ve all been thinned with a delicate crown discount to keep away from stimulating an excessive amount of re-growth or spoiling their form.

How do you prune a conifer?

Whilst you can scale back the peak of a conifer, it’s very tough to scale back the width. That is notably true of a conifer that has grown too giant.

Most conifers received’t develop again in case you lower past the dwelling foliage.

So you possibly can trim the edges of a conifer again yearly if you wish to hold it neat. That is how conifer hedges are normally handled.

However in case you don’t trim it, the branches will develop to their full size. And you then’ll be very restricted on how far again you possibly can lower.

When you lower an excessive amount of off, you would find yourself with solely naked brown wooden and no foliage. That received’t re-grow.

So if you wish to hold the scale of a conifer below management, prune it again usually.

‘Lifting the crown’

When you’re making an attempt to scale back the influence of a big, mature evergreen, equivalent to a conifer, you possibly can lower off the decrease branches. This is called ‘lifting the crown’ or ‘lifting the skirt’.

After we first moved in, over twenty years in the past, a good friend steered we take away the decrease branches from our conifer. This created far more mild across the base of the tree.

Wayne’s group took extra branches off and actually lifted the crown. This has made much more distinction and can imply I can develop extra across the tree.

Different evergreen bushes – are you able to topiarise evergreen magnolia?

Now we have an overgrown Magnolia grandiflora. It’s about 25 years previous and we’ve by no means pruned it.

A good friend steered that I topiarise it. In america this tree is usually topiarised and it seems great.

Nevertheless, Wayne instructed me that topiarising must be began younger. It will take a really very long time to get a tree to re-grow right into a form.

However in case you begin trimming and shaping when the tree is just a few years previous, then you possibly can topiarise evergreen magnolia. It’s essential to trim yearly, nevertheless, to maintain the form.

How do you prune a really younger tree?

I planted a younger silver birch within the far nook of my backyard about two years in the past.

Wayne advises me to do ‘formative pruning’. That is appropriate for younger bushes of their first few years.

‘Have a look at a really younger tree and see how the shape goes to translate to a mature tree.’

It is a good time to take off branches you don’t need or branches which might be crossing. Making a fine condition within the first few years may have advantages all through the remainder of the tree’s life.

‘When a tree’s actually younger, you possibly can take away branches you don’t need.  And also you’re solely making small wounds,’ he says. These heal higher and don’t depart marks.

‘Formative pruning is appropriate for any very younger tree.’

What about pruning a mature tree?

The biggest – and doubtless the oldest – tree in my backyard is a large Robinia ‘Frisia’ (False acacia).  It’s round 40-50 years previous.

The primary the reason why individuals need to prune a mature tree are to create a lighter cover, to ‘raise the crown’ or to ensure it’s secure.

I requested Wayne to test that it was secure. He determined to trim any useless wooden out of it, however in any other case to scale back the cover very gently by thinning it discreetly.

That is one other tree the place you possibly can’t simply chop the highest branches off and count on it to look good.

He additionally noticed an ‘included union.’ That is the place the treee has two important stems (leaders) rising upwards and so they have fused. ‘This could create a weak spot within the tree,’ he says. ‘However you possibly can take the strain off an included union by eradicating just some branches.’

Methods to prune a really upright or ‘vase-shaped’ tree

You may’t simply lower the highest off a ‘vase-shaped’ tree like my Prunus ‘Snow Goose’. It will stimulate the additional shoots and progress and spoil the form of the tree.

Nevertheless Wayne identified that we are able to skinny out the branches, in order that the tree is narrower and extra ethereal. This includes taking out entire branches, moderately than chopping branches shorter.

It retains the form of the tree intact.

How do you prune birch bushes?

Wayne defined that birch bushes are very delicate and don’t reply properly to heavy pruning. They might begin to over-compensate by rising too many new shoots or the wooden within the centre might rot.

I’ve one silver birch that’s round 15 years previous. It was wanting very dense and the benefit of birch is that it’s mild and ethereal.

At 15, it’s too late for formative pruning, however Wayne suggested a lightweight pruning to make the crown extra ethereal. He additionally identified that there was a climber within the tree, which might be eliminated.

Are climbers unhealthy for bushes?

Arborists don’t like discovering climbers rising by way of bushes. ‘When you’re making an attempt to do work to a tree or assess its well being, then a climber will get in the way in which. And it will possibly cowl up defects,’ says Wayne.

Many individuals assume that ivy, for instance, kills bushes, but it surely doesn’t. ‘Ivy isn’t a parasite, it received’t kill the tree,’ says Wayne. ‘However it will possibly cowl up issues within the tree and get in the way in which of fine pruning.’

Ivy is an excellent habitat for wildlife, particularly in winter, so there’s at all times a stability to think about, says Wayne.

When you stay in america, test whether or not English ivy is invasive in your space.

Are you able to plant 3 (or extra) bushes very shut collectively to realize a multi-stemmed impact?

After we re-vamped the backyard in 2010, there was a vogue for planting three bushes collectively in the identical gap to realize a multi-stemmed impact.

Two of my bushes failed and just one thrived. I’ve recognized a number of different individuals have comparable points, though I do additionally know one or two individuals the place this has been profitable.

Wayne mentioned that tree nurseries now extensively provide multi-stemmed bushes. It’s higher to purchase them multi-stemmed as a result of many individuals do discover that a number of bushes fail in the event that they’re planted in such shut teams.

Considered one of our three bushes died instantly. One other merely did not thrive. So we dug it up and moved it two years in the past.

‘The difficulty is that after they’re planted so shut collectively, it’s tough to dig them up with out chopping the foundation ball an excessive amount of,’ says Wayne. So the tree usually received’t do any higher in its new spot.

And certainly the tree we moved two years in the past has by no means appeared any happier in its new spot.

Wayne steered we take it out. Younger silver birches aren’t costly and we’d in all probability be higher off changing it.

Can you retain a big tree small?

Now we have a younger tree – a Liquidambar – which is round 9-10 years previous. It might develop a lot taller within the subsequent 10 years, however we need to hold it at across the top it’s now.

I requested Wayne how we should always go about this. He mentioned that we must scale back it in top inside the subsequent 5 years, then proceed to prune it again to the identical level each 5 years.

As a result of we’re beginning when the tree is just not but mature, there shouldn’t be an excessive amount of discount every time, so it shouldn’t stimulate too vigorous a re-growth.

Methods to discover a good tree surgeon

We engaged About Bushes as a result of a good friend really helpful them. These mates have a number of stunning mature bushes and I actually preferred what About Bushes had performed with them.

Yow will discover certified tree surgeons and arborists by consulting The Arboricultural Affiliation within the UK and the Worldwide Society of Arboriculturalists worldwide.

Wayne defined that tree surgical procedure is split into two abilities. One is using the gear and security. The opposite is what particular bushes want, how a tree works and the way pruning differs. That’s why merely getting maintain of somebody who can use a chainsaw might be the worst factor you do in your bushes. There’s extra about this in Tree Surgeon, Arborist or Chain-Noticed Man?

How a lot does a tree surgeon price?

I believe it’s essential to recognise that it prices cash to prune your bushes correctly. It’s in all probability the most important funding you’ll make when it comes to backyard upkeep.

I wouldn’t need to let you know that you are able to do this your self ‘simply’. Pruning bushes your self may be very harmful.

Nor do I believe it’s proper to recommend that each one you want is just a few good ideas after which you possibly can have interaction anybody who knocks on the door claiming to be a tree surgeon and providing a reduction ‘as a result of they’re within the space.’

Tree surgeons have costly gear to take care of and a excessive stage of abilities. An affordable tree surgeon received’t know as a lot concerning the bushes and the way they need to look. Good tree surgeons are additionally more likely to be booked up. They don’t knock on doorways providing low-cost providers.

When you have a small backyard with only one or two bushes, take into consideration spending a whole bunch of kilos (or {dollars}) on a great tree surgeon.

In a middle-sized backyard like mine, then you possibly can count on to consider the low hundreds. You in all probability solely should name a tree surgeon in each 5-7 years, or not even that.

You may as well minimise how usually you want a tree surgeon by selecting the best bushes in your backyard. See Jamie Butterworth’s recommendation on selecting bushes for small gardens right here.

And be sure to plant your tree appropriately. It can make an enormous distinction to the way it grows.
