The fungi that cause timber decay need three things to live and grow:
- Food source, being the wood itself
- Moisture (wood has to have a moisture content of =>20%)
What you are finding is that the poles that are weather exposed are geting wet and retaining moisture, especially in ground contact. But the internal poles are not getting wet. As they’re not getting wet, they wont rot. This is where Polesaver Rods and Bioguard Bandage can help you by significantly extending the life of your poles as part of a routine maintenance strategy.
