Tree Planting: A Comprehensive Guide

Planting a tree is a fulfilling endeavour that benefits the environment and future generations. But successful tree planting involves far more than simply digging a hole and putting a tree in the ground.

Long-term establishment starts with choosing the right tree for the site, handling it correctly and planting it to the right depth. Your planted tree then relies on suitable watering, vegetation control, protection and aftercare. Often longer than you think.

The same fundamental tree-planting principles apply whether you are planting a single tree in a garden, installing trees across a commercial landscape or establishing a larger planting scheme. However, the planting method, level of support, protection and ongoing maintenance should always reflect the tree, site conditions and overall planting objective.

This Amenity Choice guide sets out to cover the complete process and links to more detailed guidance where specialist requirements and handy tips apply.

Quick answer: how do you plant a tree?

For most tree planting:

Assess the planting site
Choose a suitable tree and planting stock
Check the tree is healthy and undamaged
Plant when ground and weather conditions are suitable
Keep roots or the rootball protected from drying
Identify the root flare and correct planting depth
Choose the appropriate planting method and prepare the planting point
Position the tree and backfill carefully
Water thoroughly
Mulch and manage competing vegetation where appropriate
Stake, anchor or protect only where required
Inspect and maintain the tree while it establishes

Before Planting: assess the site

A tree is far more likely to have successful establishment when its requirements match the planting location.

Before choosing a tree, it simply worth considering:

soil and type and structure;
drainage and compaction;
available rooting and space;
sunlight and shade;
wind exposure;
existing vegetation;
access to water;
underground and overhead services;
nearby buildings, paths or roads;
likely animal, or mechanical damage;
the tree's eventual mature size.

Poor drainage or severe compaction cannot usually be solved by simply digging a larger planting hole. New roots need to move into the surrounding soil, so the wider rooting environment matters.

For larger commercial schemes, assessment may also include soil testing, drainage investigation, rooting volume, utilities and often formal planting specification.

Choose the right tree for the right place

Consider both the purpose of planting and the condition of the site.

Trees maybe planted for:

landscape structure;
shade or screening;
flowers, fruit or seasonal interest;
biodiversity and habitat;
shelter;
woodland creation;
urban green spacing;
replacement planting

Then assess whether the species is suited to the site's soil, drainage, moisture, light, exposure to the elements, space and expected maintenance.

Mature size matters. A tree that fits comfortably when young may eventually conflict with buildings, paths, lighting, services or overhead infrastructure. Make sure you look to plan for the future.

Native species, such as alder, silver birch, crab apple, can provide significant ecological value and may be particularly appropriate for woodland, habitat and landscape planting and are often more adaptive to the UK climate. However, native does not automatically mean suitable for every site. The principle consistently remains right tree, right place.

Check tree quality and plant health

Good planting cannot fully compensate for poor-quality stock.

Before planting it is advisable to check for:

serious stem damage;
dried or badly damaged roots;
damaged rootballs;
heavily congested or circling roots;
poor tree form and shape;
obvious pests or diseases.

For professional and larger-scale planting, provenance, traceability and biosecurity should also form part of the buying process.

Where appropriate we advise using suppliers with recognised plant-health standards and that you protect planting and stock during transport, storage and handling.

What type of tree are you planting?

Different forms of planting stock need slightly different handling.

Tree stock	Key characteristics	Main consideration
Bare-root	Supplied without soil around the roots, usually while dormant	Prevent roots drying before planting
Cell-grown	Young tree grown in a compact root plug	Protect the plug and maintain correct depth
Container-grown	Established in a pot or container	Inspect roots and identify the true root flare
Root-balled	Lifted with soil retained around the root system	Protect and support the rootball
Standard/heavy standard	Describes tree size and form rather than root-production method	Larger stock often needs additional support, irrigation and aftercare

What is the best time to plant a tree in the UK?

For many trees, autumn through to early spring provides the most favourable planting conditions because temperatures are lower and moisture loss is generally reduced too.

Bare-root and root-balled trees are normally planted during the dormant season.

Container-grown trees can be planted across a wider period, provided soil conditions are suitable and adequate watering can be maintained.

Avoid planting when:

the ground is frozen;
the ground is waterlogged;
very dry conditions make establishment difficult;
extreme heat creates a high risk of water stress.

Preparing a tree for planting

Bare-root trees

Keep roots cool, moist and protected from drying winds.

If planting is delayed, temporary healing in may be appropriate. This means temporarily covering the root system with soil so that the roots remain protected until permanent planting can take place.

Do not leave bundles of bare-root plants exposed while the planting site is being prepared. Ideally plant trees within three days of receiving them.

Container-grown trees

Water the rootball if needed before planting and inspect the roots once the container has been removed.

Severely congested or circling roots may need remedial treatment, such as teasing out of the root system.

Root-balled trees

Support the rootball during handling rather than lifting or dragging the tree by the stem, to avoid root damage.

Manage wrapping, wire baskets and other rootball materials according to the tree, supplier instructions and planting specification.

Which tree planting method should you use?

The right planting method depends on the size and type of tree, soil conditions and scale of the planting scheme.

Planting method	Typically suited to	Main consideration
Pit planting	Individual trees, container-grown and root-balled trees, larger landscape stock	Prepare enough space for the roots while maintaining the correct planting depth
Slit or notch planting	Small bare-root or forestry stock on suitable soils	Roots must fit naturally without being bent, twisted or left exposed
T-notch planting	Smaller forestry or woodland stock, often on grass-covered suitable ground	Open sufficient space for the root system and firm the soil properly afterwards

Pit planting

Pit planting allows the rooting are to be inspected and positioned carefully, making it appropriate for many individual garden and landscape trees.

The planting hole should be wide enough for the roots but not unnecessarily deeper than the root system or rootball.

Slit or notch planting

A planting spade is used to create an opening into which roots of a smaller tree are positioned.

This can be efficient for larger woodland schemes, but the opening must be sufficient to accommodate the roots naturally. Do not force into a slit that is too shallow or narrow.

T-notch planting

A T-shaped cut creates additional space compared with a simple slit and can be useful for smaller stock ons suitable vegetated sites.

Planting method should reflect soil conditions and stock type rather than being selected simply because it is quicker.

How to plant a tree: step by step

Step 1 - Confirm the planting position

Before digging, check:

mature tree dimensions;
soil and drainage;
services;
nearby structures;
access;
exposure;
future maintenance.

On professional sites, follow the approved planting plan and specifications, if available.

Step 2 - Protect the roots

Keep rots or the rootball protected right up until you are ready to plant.

Bare roots should not be left exposed to drying conditions, while a dry container-grown rootball may benefit from watering before planting.

Step 3 - Find the root flare and correct planting depth

The root flare or root collar is where the trunk broadens and transitions into the main structural roots.

This is the key reference for planting depth.

The root flare should generally finish at approximately the surrounding finished soil level rather than being buried below it.

At Amenity Choice we advise customer to not assume that the top of the container or rootball is always at the correct level. Nursery soil or growing media may cover the first structural roots

Step 4 - Prepare the planting hole or planting pot

For pit planting, make the whole wide enough to accommodate the roots or the rootball naturally.

It should not routinely be deeper than required for the root system or rootball.

An unnecessarily deep hole containing loose backfill can settle after planting and leave the tree lower than intended.

If the sides of the planting hole have become smooth or compacted, carefully loosen them to improve contact around the surrounding soil.

For slit or notch planting, make sure there is enough space for the roots to sit naturally rather than being doubled back or distorted.

The aim, as with planting any plants is to achieve good root-to-soil contact and the correct final planting depth.

Explore | Installation Equipment

Step 5 - Position the tree

Place the tree upright and check the root flare agains the intended finished soil level.

For bare-root trees. spread the roots naturally without folding them into a planting point that is too small.

For container-grown trees and root-balled trees, ensure the root system is supported at the correct height.

Check the tree from more than one direction before completing the back fill.

Step 6 - Backfill carefully

Use the excavated soil where suitable, breaking up large clods and working it around the roots.

Remove obvious air gaps without compacting the soil.

Should you add compost or soil improver?

Not automatically. But a suitable soil improver can help where soil structure, organic matter or moisture retention needs improving. Use it according to the site conditions and aim to improve the wider rooting environment rather than creating a rich pocket only inside the planting hole.

What about mycorrhizal fungi?

Mycorrhizal fungi can also be a useful establishment aid, particularly when planting into poor, disturbed or biologically depleted soils. They form a natural partnership with tree roots, helping them explore the surrounding soil for water and nutrients.

When used, apply the product according to the manufacturer's instruction and ensure it makes direct contact with the roots.

Combined products are also available, such as Mycological Granular 3-3-4, which combines a mycorrhizal inoculant with a 3-3-4 fertiliser to support the establishment and early growth of newly planted trees, shrubs and other plants.

What about water-retaining products?

On sites where moisture retention is a concern, a suitable hydrogel can also be incorporated at planting to help soil retain water around the developing root system,

For example, MAD Moisture is a lignin-based organic hydrogel designed to increase the water-holding capacity of soil and growing media.
Note: Always apply it at the manufacturer's recommended rate.

Step 7 - Firm the soil

Firm the soil sufficiently to stabilise the tree and provide good root-to-soil contact.

Do not compact it so heavily that the rooting system becomes dense and poorly aerated.

With slit or notch-planting, check carefully that the soil has closed around the roots and that the tree is firmly held.

Step 8 - Water and irrigate appropriately

Watering after planting helps not only provides moisture for new root growth, but also serves to help settle the soil around the roots.

There is no single amount or frequency suitable for every tree.

Requirements vary according to:

tree and rootball size;
planting stock;
soil and drainage;
rainfall;
temperature;
wind and exposure;
season;
stage and establishment.

The aim is to keep the active rooting area adequately moist without leaving it persistently saturated.

Water the root zone, not just the surface

A wet surface does not necessarily mean water has penetrated the roots.

Apply water slowly enough to soak into the rooting system area rather than running off. Where practical, check moisture below the surface instead of judging conditions from appearance alone.

Irrigation options

For individual garden trees, careful hand watering maybe enough.

Larger landscape trees or schemes may use:

tree watering bags;
irrigation tubes;
drip irrigation;
temporary irrigation;
bowser or watering tanks.

These are watering aids, not substitutes for checking soil moisture

Explore | Irrigation Equipment

Avoid over watering

Poorly drained or compacted soils can remain saturated, reducing air within the rooting zone.

Automatic irrigation should therefore respond to rainfall, soil conditions and tree demand rather than operating unchanged through the season.

Larger tree specimens may require additional watering for several growing seasons.

Step 9 - Mulch and control competing vegetation

Mulch can help conserve moisture, suppress weeds and moderate soil conditions around a newly planted tree.

Where an organic mulch is appropriate, apply a layer of approximately 5-8 cm (2-3 in) over the soil surface.

Keep around 10cm (4 in) immediately around the trunk free from mulch so that the material is not piled up against the stem or root flare.

Do to create a deep mound, or 'much volcano' around the tree.

Gras sand weed can compete strongly with young trees for water, so maintain and appropriate vegetation-free area during establishment.

Suitable methods may include:

hand weeding;
hoeing;
mulch;
mulch mats;
other appropriate vegetation-control systems such as appropriate herbicide.

Take particular care when mowing or strimming around young trees. Damage to the bark at the base of a tree can be serious and is easily avoided by maintaining a suitable protected area around the stem.

Step 10 - Decide whether support is needed or not

Not every newly planted tree needs staking.

Support may be appropriate where:

the tree or rootball is unstable;
the tree is top heavy;
the site is exposed;
the specification requires support;
a larger specimen has been installed.

The purpose of staking or anchoring is to stabilise the root system while it establishes rather than unnecessarily immobilising the whole tree.

Step 11 - Protect the tree where necessary

Protection should be selected according to actual risk.

Potential threats include;

deer;
rabbits and hares;
smaller mammals;
livestock;
mowers and trimmers;
accidental damage;
vandalism.

Depending on the site, protection may include tree guards, shelters, mesh systems or fencing around a wider planting areas.

Do not assume one guard type is suitable for every situation. Protection should reflect the animal pressure, tree size, planting density, site and maintenance requirements. If you are unsure how to approach this the Amenity Choice Technical Team are happy to guide you through the right solution for you.

Step 12 - Inspect after planting

Planting day is only the start of the establishment.

Check newly planted trees for:

soil moisture;
stability and wind rock;
weed competition;
damaged or restrictive ties;
damaged guards or shelters;
excessive mulch;
browsing / animal or mechanical damage;
poor growth or stress.

For larger schemes, recording failures and maintenance requirements makes aftercare and replacement planting easier to manage.

Can fertiliser help a newly planted tree?

Fertiliser can useful where soil nutrient levels are low or additional nutrition is needed to support growth, but it should be selected according to the site rather than applied automatically.

Correct planting, suitable soil, adequate moisture and vegetation control remain the foundation of strong plant establishment.

When fertility is uncertain, soil analysis can help determine whether additional nutrients are needed and guide the choice of fertiliser.

In second and subsequent years, after planting, it can be beneficial to provide additional nitrogen to improve growth, using a suitable fertiliser.

If using a mycorrhizal inoculant, check the product guidance before combining it with fertiliser, as high levels of available phosphorus can reduce mycorrhizal development. Our technical team can guide you if you're unsure.

Should you use mycorrhizal fungi when planting a tree?

Mycorrhizal fungi form natural partnerships with tree roots, helping extend the area from which a tree can access water and mineral nutrients.

Many soils already contain naturally occurring mycorrhizal fungi, so an inoculant is not essential for every tree. However, a suitable mycorrhizal product can be a highly valuable edition to a tree planting programme, particularly where soils are poor, disturbed or biologically depleted.

They may be worth considering where:

soil condition or biological activity is poor;
the planting area has been heavily disturbed, such a building sites;
trees are being established in newly created or imported soils;
improved early root establishment is a priority;
the planting specification recommends their use.

For the best opportunity to establish a relationship with the tree, mycorrhizal products should normally be applied directly to the roots following manufacturer's instructions.

They should be used alongside good planting practice rather than a substitute for it. Correct planting depth, suitable soil conditions, effective watering and good after care as still the key essentials.

Note; If fertiliser is to be used along with a mycorrhizal product check the product guidance carefully. High levels of readily available phosphorous can reduce mycorrhizal development, so they should not automatically be applied together. Or you can use a combined Mycological Granular Fertiliser which combines Mycorrhizal with a 3-3-4 fertiliser We are more than happy to guide you on this and our products if you are unsure.

Can a water-retaining hydrogel help newly planted trees?

Where maintaining constant soil moisture is difficult, a water-retaining hydrogel can be a useful addition to the planting programme.

Mad Moisture is an organic, hydrogel that can be incorporated into soil or growing media, or applied directly into the planting hole when planting bare-root trees and shrubs. It absorbs and retains water within the rooting area, helping make moisture available for longer between watering events.

This is particularly useful where:

trees are being planted on drought-prone or free-draining sites;
regular watering access is limited;
large numbers of trees are being established;
reducing establishment stress is a priority;
improving moisture retention in rooting zone would be beneficial.

Mad Moisture can reduce watering requirements by up to 50% under suitable conditions and is designed to remain active in the soil for several years.
Note: It should still be used as part of a wider establishment programme. Newly planted trees should continue to be monitored for moisture stress and watered according to weather conditions, soil conditions and tree demands.

Should you prune a tree when planting?

A newly planted tree does not normally require heavy pruning simply because it has been planted.

Planting is a useful opportunity to remove clearly:

damaged and broken branches;
dead growth;
problematic rubbing growth.

Further formative pruning may be required as the tree develops, depending on the species and desired form.

Avoid unnecessary pruning purely to "balance" the canopy with the roots.

How to look after a newly planted tree?

Aftercare should focus on giving the root system the best chance to establish.

Regularly check:

water - particularly during dry weather;
weeds and grass - reduce competition around the rotting zone;
mulch - maintain where used but keep it clear of the trunk;
tree stakes and tree ties - adjust or remove as appropriate;
tree guards and tree shelters - check for damage or restrictions
tree structure - deal with damaged for problematic growth;
failed or struggling trees - investigate before replacing them

What changes for woodland and forestry tree planting?

Woodland planting follows the same core principles but introduces additional considerations such as:

stock handling and storage;
planting density and spacing;
slit, notch or other forestry planting methods;
vegetation competition;
deer and rabbit pressure;
tree guards, tree shelters or fencing;
survival assessment;
replacement planting or beating-up

Beating-up means replacing trees that have failed after the initial planting so the required stock level can be maintained.

What changes for professional landscape tree planting?

Larger landscapes may require more detailed consideration of:

soil and rooting volume;
tree pits;
drainage;
irrigation design;
establishment water supply;
lifting and handling;
staking or underground anchoring;
project specifications;
inspection and handover;
formal aftercare.

Professional planting should follow the relevant project specifications and current guidance, ideally including BS 8545:2014+A1:2026 - Trees from nursery to independence in the landscape - Code of practice

Common tree planting mistakes

Choosing the tree before assessing the site	The species may be poorly suited to the location	Match the tree to the site and objective
Allowing bare roots to dry	Root damage can occur before planting	Keep roots covered and moist
Planting too deeply	Can contribute to poor establishment	Position the root flare correctly
Forcing roots into an unsuitable slit or notch	Roots can become bent or distorted	Use a planting method that accommodates the roots naturally
Digging an unnecessarily deep hole	Loose soil beneath the rootball can settle	Dig only to the depth required
Ignoring compaction or poor drainage	Roots may struggle beyond the planting hole	Assess the wider rooting environment
Automatically adding compost or fertiliser	May not address the real issue	Base amendments on actual conditions
Treating mycorrhizal fungi as essential	Many soils already contain beneficial fungi	Use where conditions justify it
Using one watering amount for every tree	Water demand varies considerably	Water according to tree, soil and weather
Running irrigation without checking moisture	Can lead to overwatering	Adjust irrigation to actual conditions
Allowing weeds and grass to compete	Reduces water availability	Maintain vegetation control
Strimmer or mower damage	Can severely damage young bark	Maintain a protected area around the stem
Piling mulch against the trunk	Can bury the root flare	Keep mulch clear of the stem
Staking every tree automatically	Support may be unnecessary	Stake or anchor only where required
Ignoring ties and guards after installation	They can become restrictive or damaged	Inspect them regularly
Heavy pruning at planting	Removes healthy canopy unnecessarily	Prune only where justified
Planting and walking away	Problems often develop during establishment	Plan aftercare from the start

Why do newly planted trees sometimes fail?

Poor establishment is often caused by several interacting factors.

Common causes include:

incorrect planting depth;
roots drying before planting;
poor-quality stock;
unsuitable species or site selection;
drought;
waterlogging;
soil compaction;
grass and weed competition;
poorly positioned roots;
wind rock;
damaged ties or guards;
browsing / animal damage;
pests or disease.

What does successful establishment look like?

There is no single date after which every tree can automatically be considered established.

Useful signs include;

healthy seasonal growth;
stable anchorage;
roots extending into surrounding soil;
normal foliage;
reduced dependence on intensive watering;
reduced need for temporary support.

Tree size, species, soil and site conditions all influence timeline establishment.

Frequently asked questions

What is the best time of year to plant a tree in the UK?

For many trees, autumn through to spring is preferred. Bare-root and root-balled trees are normally planted while dormant, while container-grown trees can be planted over a wider period when conditions are suitable.

How deep should you plant a tree?

Position the tree so the root flare - where the stem broadens into the main roots - is approximately level with the surrounding soil.

Which tree planting method should I use?

Pit planting suits many individual garden and landscape trees. Slit, notch and T-notch methods can be useful for smaller bare-root forestry or woodland stock where soil and root conditions are suitable.

Should you put compost in the planting hole?

Not routinely. Soil improvement should be based on actual site conditions rather than automatically adding enriched material.

Should you use mycorrhizal fungi when planting?

Not necessarily. A suitable inoculant may help on poor, disturbed or biologically depleted soils, but it should not replace correct planting and aftercare.

Does every newly planted tree need staking?

Not necessarily. Use staking or anchoring where the tree or rootball needs additional stability.

Trees over 1.5m (just under 5ft) generally require staking, to provide stability especially in windy locations.

Use a sturdy stake, like the individual square tree stakes, and a flexible tree tie. The stake should be about one-third the height of the tree, and the tie should allow for some movement. Bamboo canes can also be used for support, particularly with tree guards.

How much water does a newly planted tree need?

There is no universal amount. Demand depends on tree size, soil, rainfall,. temperature, exposure and stage of establishment.

Do newly planted trees need irrigation?

Not always. Individual trees may be hand-watered, while larger schemes may use watering bags, irrigation tubes, drip systems or planned irrigation. Water should reach the active root zone and be adjusted to actual soil conditions.

How much mulch should I apply around a tree?

Apply 50 - 80 mm layer of organic mulch, such as wood chippings around the base, leave a gap around the trunk.

The benefits of using a mulch is that it retains moisture, suppresses weeds, moderates soil temperature and improves soil structure as it decomposes.

What is suggested for protecting newly planted trees from animals?

Depending on your location and the prevalence of browsing animals, consider using tree guards. For example, our 1.2m guards protects against deer, while a 0.6m guards is sufficient for rabbits. Choose biodegradable guards whenever possible to minimise environmental impact.
