Is that correct? mine FATHER-IN-LAW recommend me a few years ago to hammer copper nails right into some trees in my garden in bespeak to death them (I had too many). Once he inquiry for some copper pond at a hardware shop the assistant asked the if he want to kill part trees, so i imagine there have to be some substance come this theory. Lynda Labuhn, Bruehl, Germany (labuhn
t-online.de) NO. MINUTE amounts of copper can dissolve and pass into the sap flowing up through the trunk, however plants are rather tolerant of low concentrations - in reality copper is actually required by plants, as a ingredient of part proteins crucial for photosynthesis. And high concentrations of copper salts have long been provided to spray on tree as efficient fungicides (e.g. Bordeaux mixture - copper sulphate and lime). At best the copper object may assist to inhibit fungal strike near the wound, i m sorry would generally heal v time. Of food the copper might be a difficulty later if the tree is sawn for timber. Ken Joy, (lsrak
csv.warwick.ac.uk) THIS may be true if the piece of copper is the shape and also size of a large axe. Wilhelm Hamlin, Ontario, Canada. Throughout my years as a tree operated doctor I have come throughout the "copper nail" myth numerous times. Part years ago, as soon as cutting up the trunk of a commonly vigorous poplar, i came throughout a ring that copper nails. Number of inches within the wood, the tree had actually enclosed them and carried on growing with no ill effects. Geoff March, Stroud, Glos. TO know the potential affect of embedding a poece of copper in a tree trunk on the long term wellness of the tree, some simple plant physiology and also chemistry demands to be considered. In order to kill a tree, a toxin have to interfere with cell division in the regions from i m sorry a tree grow - root and also shoot tips and the cambium, a ring of dividing cells inthe stem and also roots. In addition, inhibition that a crucial process such together photosynthesis will have a similar deleterious effect. Implanting a piece of copper in a tree trunk will certainly only impact such crucial processes if the copper is transported native the implant come the roots and shoots. There space two paths that copper could take. The very first is in the xylem, the woody tissue that forms the bulk of the tree trunk (wood) but likewise forms the main transport path for water native the soil, via the roots to the leaves. Movement below is controlled by the rate of water loss indigenous the leaf and this process is regulated by stomata on the under surface of the leaf. Products move passively through the flow of water, back those v a hopeful charge will solve to negative charged web page in the wall surfaces of the xylem tissues. The phloem organization (bark) is very specialised and also is responsible for deliver of assets of photosynthesis from pipeline to shoots and roots. It can rapidly seal off any type of injured tissues. Copper from an implant would have to dissolve before it can move to roots or shooting and impact plant vitality. The pH the the phloem and also xylem sap is contempt acidic (pH 5 - 6) so some copper would progressively dissolve. Copper binds preferentially come the xylem tissue and also shows restricted mobility as a cation. It readily forms stable necessary complexes with tiny molecules such as amino acids and appears to relocate through the xylem in this form. These complexes are an extremely stable and also may no dissociate at the finish of the move pathway. If so, these will not easily pass throughout biological membranes and also inhibit metabolic activity. Copper motion from leaves, via the phloem is really slow for this reason the redistribution via this organization from an implant would additionally be slow. The slow rate of copper relax from a metallic implant would certainly be unlikely to cause far-reaching problems for a healthy and balanced tree. As the main route to living tissue would be via the xylem, the patterns of water activity within a tree would additionally be important in the subsequent transport of copper. These vary v tree types - in some water ascends straight up whilst in others, water motion occurs in a spiral of verying pitch. Numerous implants would be required to make details that all parts of the tree crown were got to by copper. In conclusion, ns would take into consideration it unlikely the a single copper implant would prove fatal come a healthy and balanced tree; one old or already debilitated tree may prove to be an ext susceptible.

livjm.ac.uk) Well..... That eliminated it! Mac, shrewsbury uk I had actually a young witch hazel tree in my garden for some years which to be flourishing, so lot so that I essential to support one of the branches. Without yes, really thinking around it, I supplied a length of copper piping together a stake close to its roots. When I noticed the branch had died for part mysterious factor it didn"t take place to me to eliminate the piping straight away. By the moment I walk the entirety tree had actually died. I have left it in the expect it might revive from the bottom (without the piping there obviously) yet I"m not confident as it"s usually flourishing catkins in January and also so far...nothing. RIP tree. Jane, London UK too ~ Dr.Nicolas, as a researcher in Egypt horticulture institute i am interested in copper and its movement in trees. I review your elegant write-up of copper implant to death trees. I"ll be really glad come tell me around ways come hinder or protect against copper native entering or penetrating in trees for study purposes. With ideal regards Hamdy Elzayat, Cairo Egypt Copper salts and ammonia are reliable at dissolving cellulose. This is exactly how viscose and also cello tape room made. Cellulose is the main component of plants. I think this is the reasoning behind the idea. An immediate cold pack and also some plain (no enamel) copper wire in a hole in the tree might work. Paul, columbus USA correctly a copper spike right into the trunk of a sawn turn off tree ensures no re-growth, to kill the tree the hasn"t to be chopped under - use a knife and also cut the bark around the stems a 2 customs strip completely around... The tree will die. DeeJay, UK include your answer
