Interesting Tree failure - girdling roots?

[Gary Prentice]

How would this have been rectified at the planting stage, by inspecting the root mass and ensuring they aren't girdling/wrapped up too much?

The trunk is an odd shape considering there are no lateral roots there, it does look like it has a small buttress (prominent in the second photo with classic hippocastanum twisting of the trunk).

Thanks for sharing.

 

Lots of articles out there, but generally these issues start really early in the trees development when they're not moved on from the first trays or pots that the seed is planted in. The roots encircle the pot, get transplanted into a larger pot and the problems just buried to emerge years later.

 

Airpots are meant to be really good in preventing this.

 

If you do much bare-root stock planting you'll often be able to see roots that aren't growing radially but are growing round in circles. They should be either root pruned to encourage radial rooting or discarded.

Thanks for the info, those Airpots look good!

Good tips Gary!

Apparently there's lot's of interest in their use if you want to grow things in the attic under growlights:confused1:

I have seen exactly the same type of failure here in Sheffield on Norway maple due to entirely girdled roots (although a bit of decay contributed here too). My theory is they are container grown trees, left too long before potting on, and then plonked in the ground without any root pruning.

Attics full of early mature Cedrus libani with branches popping out through the roof tiles?

[Gary Prentice]

Yeah, it's becoming a bit of a problem.

is it just me or are the pics gone?

[Gary Prentice]

Nope, they've gone.
