Short answer. Fibreglass tree supports and plant stakes do not rot and flex with the tree; wood is cheaper but decays and stiff stakes can rub or girdle the trunk. Whatever the stake, support loosely and for a limited time so the tree builds its own strength.
| Fibreglass stakes | Wood stakes | |
|---|---|---|
| Rot and insects | None | Decay at ground level |
| Flex | Flexes with the trunk; springs back | Rigid; can break |
| Reuse | Many seasons | Often single use |
| Handling | Light; pointed tip | Heavy, splinters |
| Cost | Higher up front, lower over reuse | Low |
How to support a young tree
- Use one or two stakes on the windward side, placed outside the root ball.
- Tie low on the trunk with a soft, wide tie that allows some movement; check yearly so it does not cut in.
- Remove the support after the tree is established (often after one or two seasons) so the trunk strengthens.
- Choose length from the planting depth and the height the tree needs support to; see the length rule in fiberglass stakes and markers for the same approach.
The same pultruded rod is used for plant stakes, driveway markers and signage: solid vs hollow fiberglass rods.
Choosing length and when to stake
- Stake length = depth in the ground (often 40–60 cm for a young tree) + the height up the trunk where support is needed.
- Only stake trees that cannot stand upright alone or are in exposed or windy sites; unstaked trunks strengthen faster.
- Use a soft, wide tie that allows movement; never wire directly around the trunk.
- Check ties each season and loosen them as the trunk thickens.
- Remove stakes once the root system holds the tree, usually within a year or two.
Frequently asked questions
Can fibreglass stakes damage a tree?
Not if the ties are soft and loose. The risk comes from tight or abrasive ties and stakes left too long.
Can I reuse fibreglass stakes?
Yes: inspect them for splinters or damage before reuse and discard those with exposed fibres.
