This step-by-step guide covers how to correctly stake a mature tree using two stakes and a crossbar. This guide is suitable for large trees with a single stem over 2.5 metres in height.
If your tree is under 2.5 metres, please see our other guide on How to Stake a Small Tree.
What's in this guide
Do I need to stake my tree?
If you're planting into the ground and your tree has a single stem, yes. If it's a bush or multi-stem tree, or you're planting your tree into a pot, we don't recommend staking.
Why do I need to stake my tree?
Staking is an important step in the planting process as it will help the tree’s roots to anchor into the ground properly during the first few years of growth. It helps to prevent the roots from moving around too much—this is an issue known as root rock which can lead to establishment issues. Staking is particularly important in areas prone to high winds.
How long does my tree need to be staked for?
Large and extra large stakes can normally be removed after about 3-5 years in the ground, provided the tree has established well.
What you will need
- Large or Extra Large stake & tie kit (these come with two stakes, a cross bar, belting, a rubber space block, four long nails, and four short nails)
- Lump hammer
- Claw hammer
- Saw
- A friend or family member to help (it's much easier with two pairs of hands)
Step 1: Position the stakes correctly
Get your planting hole ready and place your tree inside. Then, before backfilling, position your stakes on either side of the rootmass, slightly off centre of the stem to allow enough space for your crossbar (about an inch or two).
Once the tree is staked, the stem needs to blow away from the crossbar in prevailing winds. So, at this stage, when you are positioning your stakes, you need to consider on which side of the stem your crossbar is going to end up.
Step 2: Knock the stakes into the ground and backfill
Once you’ve positioned your stakes correctly, use your lump hammer to knock them into the ground until they are firm. Take care not to penetrate the rootmass.
Backfill with your soil and compost mix around the tree and stakes. Take care not to bank the soil up over the collar or graft union of the tree as this can cause rotting. Gently press the soil to firm it.
At this point, remove the bamboo cane, if the tree comes with one.
Step 3: Attach the crossbar to the stakes, removing any excess length
Attach the crossbar to the stakes, using your claw hammer and four long nails. Remove any excess length from the crossbar using your saw, if desired.
Step 4: Install your belting and space block
hread your belting through the rubber space block and wrap around the stem, at a level with the crossbar. The belting should be wrapped firmly enough to support the tree but not so tight as to restrict the tree’s growth. Make sure the rubber space block is positioned correctly between the tree and crossbar, to prevent rubbing.
Attach the belting to the crossbar using your claw hammer and short nails, making sure the tree remains upright.
