A stump that wont die

Recommended Posts

Here’s (what I thought) a really good animation aimed at school children which touches on the subject of inter connectivity between trees, roots & fungal associations. 

 

It might be a bit too advanced for here but worth a punt....  Alternatively, there’s always the drill ‘n fill option 🤪 but bare in mind, it may have greater adverse implications than initially thought....

I don't think is too advanced - good vid about mycorrhiza mainly.

In the vid I posted the amazing thing is, despite the stump having NO LEAVES  its still alive!!!!  

I think you are right about the implications of drill and fill on tree stumps (with root graft potential). Worth considering In some situations

Interesting article, especially the research on water flow in the stump being directly related to flow in neighbours. I have read in one of my books (can't remember which now) about this water flow thing, my wife still teaches that transpiration pulls water through a tree in biology classes but it must be more complicated.

How does water get up the tree in spring when sap rising? And when I lop branches off why do I sometimes get sap flowing out of the cut ends (esp birch, maple)? In fact, how does a pollard survive?

How does water move through plants to get to the top of tall trees? Here we describe the pathways and mechanisms...

It's to do with chemical potential.
