Why White Paint Works
White reflects sunlight.
Dark bark absorbs it.
That’s the entire secret.
By reflecting sunlight instead of absorbing it, the white coating keeps the trunk cooler during the day.
This prevents drastic temperature swings.
The bark stays stable.
And stable bark doesn’t crack.
But not just any paint is used.
Caretakers typically apply:
- Diluted, water-based latex paint
- A breathable coating that won’t suffocate the tree
- No oil-based or chemical-heavy paints
The goal is protection, not sealing.
