Burr and growth.

[woody paul]

Looked at a Horse Chestnut a couple of months ago which i also looked at a year ago and quoted to carryout work on it, which was to Reduce large limb and tip prune by 1 meter and find any dead wood and rot/cavities. The reason to tip prune was to find any decay at tips because it has declined i the last couple of year and dropped leaves early.

Me question is the tree is covered with burrs will this cause less growth and stress to tree because carried out work on it this afternoon and no sign of any major decay any were.

These are some of the limbs with burrs we removed but the whole tree is covered.

Was it a red chestnut, Aesculus x carnea ?

 

if it was, they are prone to burrs on the trunk, main scaffolds and lesser branches.

 

presumably due to being a hybrid.

The burr type lumps on red HC appear to look more  like canker to me , at least in the ones I have seen and know of locally , plain HC often have plenty of burrs as I always seek these out as I do a fair bit of woodturning and they are very desirable indeed !!  As to the OP, I have no idea if it affects the growth rate but I know of some fine, big  healthy specimens with plenty of burrs on them and do not appear to be suffering poor vigour .....
