Staking a tree properly is crucial to helping it become established and grow strong, especially when dealing with young trees or trees in windy areas. Proper staking provides support, prevents damage, and encourages trees to grow stronger on their own. Here is a comprehensive guide on how to stake a tree correctly.
Why Stake a Tree
Staking a tree is an important process for several reasons:
- Provides support – Staking gives young trees extra stability so they can stand upright while their root system develops. This prevents them blowing over in wind or storms.
- Prevents damage – A staked tree will not sway or rub against its supports which prevents bark damage. Bark damage can allow disease and insects to attack the tree.
- Encourages strong growth – As the tree grows, the stakes will gently move with the tree allowing the trunk to strengthen. An unstaked tree may develop a weak trunk if it sways too much.
- Trains growth – Stakes can be used to train or straighten tree growth, especially with grafted or high-canopied trees.
- Transplant support – Newly transplanted trees benefit greatly from staking as their roots recover from being dug up.
Knowing why staking is important will inform how and when you need to stake trees. Next, let’s look at when staking is necessary.
When to Stake a Tree
Staking is recommended for:
- Newly planted trees – All new plantings under 3 years old benefit from staking as their roots establish.
- Small, young trees – Trees less than 2 inches diameter are too thin to properly anchor themselves. Staking prevents blowing over.
- Top heavy trees – Trees with dense canopies or grafted tops need staking so their weight doesn’t uproot them.
- Windy locations – Trees planted in open, windy sites should be staked to protect against winds.
Staking is usually not necessary for:
- Older established trees – Trees over 3 years old have developed anchoring root systems.
- Large mature trees – Thicker trunked trees do not require staking.
- Still, sheltered sites – Trees not subject to wind forces may not need stake support.
Evaluate your tree’s age, size, canopy, and site conditions to determine if staking is beneficial. Move on to the next section to learn about the different staking techniques and materials to choose from.
Types of Staking Techniques
There are several common tree staking methods, each with pros and cons:
1. Simple 1-2 Stake Support
This involves 1 or 2 stakes driven in the ground and attached to the tree with ties.
Pros: Simple, inexpensive, easy to install. Good for younger trees.
Cons: Only provides minimal support, can still allow some swaying movement.
2. 3-Point Support Triangle
Three equally spaced stakes are angled out and secured with ties to form a triangle around the tree.
Pros: Provides excellent stability for root establishment. Allows some trunk movement yet prevents excessive sway.
Cons: More complex to install properly. Can be less aesthetically pleasing.
3. 4-Point Support Square
Four stakes are evenly spaced and driven vertically around the tree then secured with ties.
Pros: Maximum stability support, especially in high winds. Good for large top-heavy trees.
Cons: Most complex to install. Allows little trunk movement as tree grows. Can inhibit root establishment.
4. Guy-Wire Support
Involves running diagonal wire cables from stakes to an eye-bolt in the trunk to anchor the tree in place.
Pros: Allows great flexibility control. Can be installed on larger mature trees.
Cons: Requires special equipment and know-how. Wires can be hazard in high traffic areas.
Evaluate the level of support needed for your tree and site to determine the best staking method. Next we will look at suitable staking materials.
Staking Materials
There are many choices when it comes to staking materials:
- Wooden stakes – Readily available and cost effective. Need to be thick enough not to split from pressure.
- Metal rebar – Very strong support but aesthetics may be undesirable in ornamental sites.
- Metal stakes – Manufactured stakes that are reusable, strong, and last many years.
- Deadman anchoring – Burying a concrete block or horizontal wood stake to tie off to underground.
- Tie wires – Plastic covered wires that prevent abrasion damage. Biodegradable ties available.
- Hose sections – Short sections of garden hose to cushion and prevent cutting by ties.
- Flagging tape – Bright tape that acts as a visual cue to prevent lawn mower damage.
Choose your materials based on durability, aesthetics, and functionality. Avoid thin wires or small stakes that can cut into the bark. Now let’s go over how to properly install stakes.
How to Install Tree Stakes
Follow these steps for proper stake installation:
1. Install Stakes Before Planting (if possible)
Ideally stakes should go in the ground before the tree is planted. This prevents root damage from driving stakes into an established tree’s root zone.
2. Position Stakes Beyond Rootball
Stakes should be placed 6-12 inches outside the rootball or 1/3 the distance from the trunk. Avoid penetrating the root system.
3. Align With Prevailing Winds
Orient stakes perpendicular to the prevailing wind direction for maximum support.
4. Drive Stakes Deeply
Stakes should be driven at least 1 foot deep into undisturbed soil to properly anchor them. Deeper for larger trees.
5. Allow Trunk Flexibility
Do not drive stakes flush to the trunk. Leave a 1-2 inch gap to allow some flex and prevent rubbing.
6. Attach Ties Securely But Not Tightly
Use proper tree ties to firmly attach stakes to the tree using a figure 8 pattern with hose protectors. Do not cinch ties overly tight – allow for some movement.
7. Check Ties Frequently
Inspect ties regularly and adjust to prevent girdling as the trunk grows. Remove stakes once tree establishes.
Properly installed stakes will provide good support while still allowing the trunk to strengthen and the roots to establish. Next let’s go over correct tie placement.
How to Secure Ties and Straps
Follow these guidelines when attaching ties between stakes and the tree:
- Place ties 18-24 inches above the ground to allow room for root flare development.
- Use wide, flexible ties to spread out forces on the trunk. Avoid small wires that can cut in.
- Attach ties firmly so they don’t slide or rub on the bark. But not overly tight.
- Position so ties support weight of tree but still allow some movement.
- Use hose or special sleeves to cushion the friction point between the tie and tree.
- Start with loose ties and tighten gradually as tree grows to prevent girdling.
- Angle ties downwards firmly to redistribute weight down through the stakes.
- Check ties regularly and adjust to accommodate trunk expansion and prevent girdling.
Proper tie placement is crucial to prevent damage while supporting the tree. Now let’s look at when to remove the stakes.
When to Remove Tree Stakes
Stakes should be removed once the tree establishes a strong root system and can stand on its own. This is typically:
- After 1-2 years for smaller young trees.
- After 2-3 years for larger transplanted trees.
- Once the trunk has thickened and matured enough to resist wind sway.
Look for these signs to determine your tree is ready for stake removal:
- Tree trunk thickens and stands firmly without staking.
- Roots have visibly expanded into surrounding soil.
- Soil has firmly re-settled around original rootball.
- Tree resists moving when lightly pushed from various angles.
- Lower branches and twigs show good wind resistance.
- Tree successfully survives a windy season unsupported.
Gradually remove ties and stakes over a 7-10 day period. This allows the tree to adjust to supporting itself fully. Avoid removing stakes just before or during windy months.
Now that you know how and when to stake trees properly, let’s look at some common mistakes to avoid.
Staking Errors to Avoid
There are some key mistakes that can negatively impact staked trees:
- Leaving stakes on too long – Can inhibit trunk strength and root expansion.
- Stakes too tall – Only stake as high as needed to stabilize top growth.
- Ties too tight – Should allow some trunk flexing to strengthen naturally.
- Ties too low – Position high enough to allow root flare to develop.
- Penetrating roots – Avoid driving stakes through the mature root zone.
- Allowing stakes to rub – Check often for abrasion and adjust ties.
- Using small stakes – Larger stakes better resist wind forces.
- Letting ties girdle – Loosen ties gradually as trunk expands.
- Staking late – Stake immediately at planting for best protection.
Be sure to avoid these detrimental practices when staking a new tree. Proper technique will give it the best chance of growing into a beautiful, healthy specimen.
Now that you know how to correctly stake a tree, let’s look at some frequently asked questions.
Frequently Asked Questions
Should all new trees be staked at planting?
Not necessarily all, but staking is recommended for most new plantings under 3 years old to protect them as their roots establish. Exceptions would be large stock, extremely sheltered sites, or trees less prone to wind damage like arborvitae. Evaluate the need on an individual basis.
How long should stakes stay on the tree?
Most trees need 1-2 years of staking support max. Monitor growth and remove stakes once the tree shows it can stand alone without swaying excessively. Never leave old stakes on neglected trees.
Can you stake an older, existing tree?
Staking older trees is not normally recommended. Their roots are established and stakes may inhibit development. For at-risk mature trees, use flexible cabling or expert bracing methods that minimize growth impacts.
Should tree ties be tight or loose?
Ties should be firm enough to secure the tree, but loose enough to allow some flexing movement of the trunk. This strengthens naturally while preventing excessive rubbing. Ties can be gradually tightened as the tree grows.
What kind of material should I use to tie the tree to stakes?
Flexible, wide tree ties made of rubber or plastic are ideal. These avoid damaging the bark like wires while still being adjustable and durable. Wrap with hose sections to further reduce abrasion.
How can I avoid damage when removing tree stakes?
Gradually loosen ties over 7-10 days before total stake removal. This allows the tree to slowly adjust to supporting itself again. Remove stakes carefully to limit nearby root impacts. Refill stake holes to prevent new damage. Monitor tree health after removal.
Conclusion
Staking young and newly planted trees is an essential process to help them establish strong root systems and wind-resistant trunks. Take care to choose staking methods, materials, and tie placements that provide adequate support without inhibiting natural growth. Avoid common mistakes like leaving stakes on too long or using ties that damage the bark. Monitor your tree’s progress and remove stakes promptly once the tree matures enough to stand unassisted. Patience and proper technique will result in successfully anchored trees that grow and thrive for years to come. With this comprehensive guide, you now have the knowledge to properly stake a tree!
