The best way you plant a tree makes an enormous distinction as to whether it is going to survive.
A badly planted tree received’t essentially fail within the first yr, in accordance with award successful backyard designer Jamie Butterworth, MD of Type Vegetation tree and shrub nursery. However it is going to fail sooner or later.
And a tree will be fairly an funding within the backyard. We’re all being urged to plant timber as a part of bettering air high quality and re-foresting our surroundings. But when the timber aren’t planted correctly, that point, effort and cash will likely be wasted.
Type Vegetation sells specimen and specifically formed timber and architectural vegetation to backyard designers, and likewise to most people.
So I requested Jamie how you can plant a tree correctly. His recommendation additionally made me look once more at a few of the timber, I’ve planted in my very own backyard. Then I realised that some have been planted fairly badly. There are three widespread issues, so I’ll clarify how we sorted every one out.
How you can plant a tree correctly
Jamie says that an important factor is to plant your tree on the proper depth. The purpose at which the roots be part of the trunk must be degree with the bottom. If the roots are planted too deeply, the tree will fail.
Some folks will advise you to dig a spherical gap. Others say it should be sq.. Jamie says that he has investigated analysis on each strategies rigorously and it doesn’t appear to make a lot distinction.
There’s some debate as to how large the opening ought to be. If you happen to apply no dig/no until gardening, you solely dig the opening as large as the present tree roots. Go away the soil across the gap undisturbed.
If you happen to backyard historically, you’ll be informed to dig a gap two or thrice as large because the tree roots. And loosen the soil across the gap.
Both method, fill the opening with water and let it drain.
We positioned the tree within the gap and laid a stick throughout it to verify the extent was proper.
Be sparing with compost however add mulch on prime of the soil
As soon as the tree is positioned within the gap, Jamie suggests that you simply use the soil you may have dug out of that gap to backfill it. ‘You could possibly add some compost, however don’t add an excessive amount of,’ he says. However add one other layer of mulch on prime of the soil across the tree, as that may feed the soil close to the tree and encourage the roots to unfold.
How you can plant a tree accurately. Use a smooth, versatile tie and a pure wooden stake. Take away each after a yr or so.
Utilizing tree stakes and ties
A younger tree wants staking for the primary yr or two. Jamie says you must use a pure wooden stake, not one which has been handled. ‘Individuals usually neglect to take the help away, or they transfer home,’ he says. ‘However a tree shouldn’t be supported for too lengthy. A pure wooden stake will biodegrade over time. He suggests utilizing biodegradable ties for a similar cause.
Tree ties ought to versatile, too, in order that they don’t reduce into the tree when it blows within the wind or grows. I’ve used BioStretch smooth backyard twine and BioStretch Tree Ties. Each biodegrade and fall off in round 2 years.

How deep must you plant a tree?
A tree ought to be planted as deeply as its root ball, says Jamie. The place the place the trunk flares to satisfy the foundation ball ought to be degree with the bottom. If the tree is buried too deeply, the trunk will stick straight out of the bottom like a pencil. You received’t be capable to see the flare because the trunk joins the roots. The trunk is more likely to rot, and, sooner or later, the tree is more likely to fail.
Jamie Butterworth says that the primary mistake when planting timber is planting them too deep. The foundation junction with the trunk must be degree with the bottom so as to simply see the flare because it widens out. In case your tree goes into the bottom as if it have been a pencil, the roots are too deep.
‘Don’t depend on the tree being planted on the proper depth within the pot,’ he says. ‘You might have to clear away some mulch or compost to establish the foundation junction.’
When is the very best time of yr to plant a tree?
The most effective instances of yr to plant a tree are autumn and spring. Don’t plant in winter, if the bottom is frozen. However you probably have gentle winters, you too can plant then. If you happen to plant your tree in summer season, the climate could also be too scorching and dry, so the tree will wrestle to get established. Nonetheless, common watering will assist the tree survive.
How you can take care of newly planted timber
Newly planted timber want some care or they could die. An important factor is to ensure they’re watered recurrently in dry climate. If you happen to’re planting neighborhood timber, ensure there’s a rota or that somebody is accountable.
You don’t must fertilise timber, however add a layer of mulch or compost on prime of the soil across the tree. Be sure to don’t cowl up the trunk, although. Jamie makes use of peat free Dalefoot Wool compost.
Don’t enable weeds, grass or different vegetation to develop too near the bottom of the tree.
Take away stakes and tree ties after 1-2 years.
What to do in case your tree has been planted mistaken
So after our go to to Type Vegetation I checked out a few of the timber at dwelling. A number of had been planted badly, primarily by me.
Let’s begin with planting a tree too deep. I just lately wrote about what to do with a troublesome shady nook the place a pergola had collapsed. I made a decision so as to add one other silver birch tree to the backyard, plus some simple shade loving planting. Silver birches don’t like a really shady spot, however as quickly because the tree grows larger than the wall behind it, it is going to get loads of solar.
So I planted a silver birch, however forgot to consider the depth of planting. Because of this, a small quantity of the trunk is certainly below the earth. I’ve planted it a few inches too deep.
I additionally planted some comfrey close by. However comfrey will be fairly invasive and it unfold to the bottom of the trunk. Timber, particularly newly planted ones, want a lot of vitamin from the soil. They don’t do effectively if grass, weeds or vegetation are planted too shut.
And I’ve simply used a slender bamboo cane to help this tree. It’s not ample. Plus I’ve allowed comfrey to develop proper as much as the bottom of the trunk. I actually was not concentrating after I planted this!
What to do in case your tree has been planted too deep
If it’s a reasonably younger or just lately planted tree, it ought to be secure to dig it up and re-plant it on the proper depth. As I solely planted this silver birch six months in the past, there’s unlikely to be any drawback re-planting it.
I’ve seen that the longer a tree or shrub has been within the floor, the much less doubtless it’s to outlive being moved. However younger timber and vegetation will be moved fairly simply, so long as they’re re-planted correctly.
Typically you possibly can scrape away the soil…
I’ve a liquidambar tree that seems to have been planted too deep. It was planted by somebody who used to assist me within the backyard round 5 years in the past. It’s on a slight slope. So he tried to make it possible for water would go down into the roots slightly than sliding down the slope by piling up the soil in a circle across the trunk. He left the bottom of the trunk freed from soil in order that there was a bit of effectively or moat simply across the base of the tree.
However, over time, the soil has washed into the effectively space and buried the junction the place the trunk meets the roots.
So we scraped again the soil to disclose the junction with the roots. As he’d piled soil up, it was comparatively simple to take it again to the correct degree.
Trying again at earlier posts, I found that I had planted two holm oaks too deeply in 2014. That they had each been pushed over by a storm. Nonetheless, as soon as once more, the soil had been constructed up round them, so we didn’t dig them up. We scraped the soil away. It was an actual pleasure to match what the holm oaks appeared like then to what they seem like now.
When these two holm oaks have been pushed over in a storm about three years after they have been planted, I assumed they wouldn’t survive. However the prime picture exhibits how they appear now.
Different tree planting issues – what to do
It’s best to take away tree stakes and ties inside two years. Certainly one of my timber has been staked for round 5 years, so we’ve eliminated it.
You possibly can simply see {that a} tight tie has been left on this tree, slightly below the soil so we hadn’t seen it. If a good tie is left on a tree, it cuts into it and damages the tree because it grows. It may even in the end kill the tree.
Whereas I used to be checking the liquidambar planted round 5 years in the past, I additionally found {that a} tie had been by accident left on. I feel it was a part of the labelling. It was digging into the trunk because the tree grows. This could in the end trigger tree dying.
These issues are simple to type. It’s only a query of taking off any tight labels and eradicating the stakes.
Tree planting issues with an older tree
The third drawback tree was one other silver birch in the back of the backyard.
Round eleven years in the past, we redesigned the backyard. I used to be nonetheless an inexperienced gardener. There was, I feel, one thing of a trend for planting three timber in the identical gap or very shut. The concept was that it could mimic a multi-stemmed impact. And it could prohibit the expansion of bigger timber in small gardens, as a result of they’d compete for vitamin.
Nonetheless, personally, I’ve by no means recognized this technique of planting three timber very shut collectively work. I solely know just a few individuals who have really executed it, in order that’s not a scientific statement. However it’s additionally been a while since I even heard this system beneficial.
These two timber have been planted eleven years in the past, together with a 3rd tree which rapidly died. As you possibly can see, one tree has flourished whereas the opposite has barely grown. The concept is that this technique restricts the expansion of bigger timber in smaller gardens. Sadly, it doesn’t appear to limit the expansion of all of them equally.
One tree had extra daylight and was planted higher. It has thrived. One tree was planted too deep and had much less daylight. It seems to be fairly depressing. The third tree died quickly after planting, so we took it out. However the distinction between the wholesome tree and the tree that has barely grown is now fairly apparent.
Nonetheless, this tree could not like being moved, because it’s been in situ for therefore lengthy.
However there’s no level in leaving it the place it’s. So we dug it up and has moved it to someplace it will probably get its personal share of sunshine and vitamins. It’s additionally now planted on the right depth. We will see if it survives.
