Glyphosate affected yew tree

[swinny]

What poison should be used on stumps in general then?

 

Is thios just a case of graftged linked roots on yew? or can apply to other tree's?

 

What poison should be used?

 

Cheers

we had same thing happen to a beech when treated stumps near to it, i put it down to root grafts ,3 years later the beech seems ok but had to remove a few limbs that didnt do so well.

 

thats evidence I wanted to confirm the connective branch to root subject on fagus, thanks ben, thats a gem mate.

 

dont suppose you documented it with photos?

I always thought that glyphosate only works if applied to the growing leaves of a plant, applying it to a stump kills nothing especially adjacaent trees. I was only allowed to use roundup on the canals because once it hits the bare ground it is neutralised and wont not kill any aquatic life when washed into the water after a heavy rain.As for killing the stumps i used to cut a channel around the cabmium layer and apply petrol, worked for me.

Glypho works buy inhibiting an enzyme that plants need to grow. It is absorbed into the plants transportation system, so gets passed to all parts of a plant including its roots which is why it is effective when applied to freshly cut stumps. It is absorbed into the roots and kills them preventing the stump from re-sprouting.

 

In the OP's case, the Glypho has affected the roots of a neighbouring tree because the tree is the same species and in all probability, underground and out of sight, the roots of the two tree had become fused/joined together. So the poison has passed directly from the roots of the stump to the roots of the retained tree.

Could root pruning be an option to prevent further poison transfer? (a trench dug between the stump and live tree)

 

Sorry
