using an angle-grinder to cut down live Leylandii
In message , Janet Baraclough
writes Thanks for all your help folks. Now, can anyone tell me *why* copper nails are going to work? They aren't, afaik; hammering hundreds of copper pennies into ancient trees for luck, doesn't kill them. (It's a tradition in some places). So my nocturnal hammerings were fun but in vain - oh well. -- dave @ stejonda calculate your ecological footprint http://www.lead.org/leadnet/footprint/ Coins hammered into trees were traditionally often silver. Coins are also relatively small and only hammered a relatively short way into the bark of the tree, so cause no real damage. The issue with hammering copper nails into the trees to kill them comes from the chemical imbalance that is caused by introducing too much copper into the plant/tree's system. Copper is needed by plants to grow, but like many things, too much of a good thing can be bad for you. The same goes for plants and trees. Various trees/plants may have varying tolerances for too much copper, so depending on the type of tree, age, size, etc. the number of copper nails needed to kill a tree may vary immensely. Hope this helps, though I understand the offending trees have now been removed by mechanical means. Best thing that could have happened to them. Dave. |
