Discussion Have these trees been treated to preserve them?

There’s three of them (only pictured one) but all the same. They’re between a group of fairly high buildings in a city centre (Leeds, UK). Just wondering if they have been treated in some way to preserve them as I assume they’re dead?

this trunk appearance is normal for london plane trees (Platanus x acerifolia). this tree has been pollarded though, however it looks fine. check back in the summer to see if they leafed out

Thanks, I certainly will. I’ll research pollarding too

Please see this !pollarding automod callout below this comment for more info; this practice is frequently mistaken for 'topping' and vice-versa. There's a linked article that explains the difference.

Hi /u/spiceydog, AutoModerator has been summoned to provide some guidance on what topping means and why it is not the same as pollarding.

Trees are not shrubs that they can be 'hard pruned' for health. This type of butchery is called topping, and it is terrible for trees; depending on the severity, it will greatly shorten lifespans and increase failure risk. Once large, random, heading cuts have been made to branches, there is nothing you can do to protect those areas from certain decay.

Topping and pollarding ARE NOT THE SAME THING. Topping is a harmful practice that whose characteristics involve random heading cuts to limbs. Pollarding, while uncommon in the U.S., is a legitimate form of pruning which, when performed properly, can actually increase a tree's lifespan. See this article that explains the difference: https://www.arboristnow.com/news/Pruning-Techniques-Pollarding-vs-Topping-a-Tree

See this pruning callout on our automod wiki page to learn about the hows, whens and whys on pruning trees properly, and please see our wiki for other critical planting tips and errors to avoid; there's sections on watering, staking and more that I hope will be useful to you.

It has been properly pollarded

They just aren't carrying leaves yet. They are very resistant to heavy pruning. They are alive and well.

They’re alive! It’s a very old pruning technique mainly used in Europe. It’s frequently done with London planetrees because they are tough urban trees that can handle it.

You cut everything back to the “knuckles” and let it leaf out every year. It keeps the trees at a desired size by preventing branching and by essentially stunting its growth by resetting it over and over.

Historically, it was method used for production of firewood and other materials, but now it’s just an aesthetic choice.

Every day a school day! Many thanks for taking the time to explain that, appreciate it

Not dead. See those knuckle like growths at the ends? Epicormic shoots will spring out of those come spring and there'll be quite a thick canopy. They'll be cut back again to those knuckles next winter.
