Is the correct? my FATHER-IN-LAW advised me a few years back to hammer copper nails right into some trees in my garden in stimulate to death them (I had too many). Once he request for part copper nails at a hardware shop the assistant asked that if he want to kill some trees, so ns imagine there should be some substance come this theory. Lynda Labuhn, Bruehl, Germany (labuhn
t-online.de) NO. MINUTE quantities of copper might dissolve and also pass into the sap flow up with the trunk, yet plants are quite tolerant of short concentrations - in fact copper is actually needed by plants, as a ingredient of part proteins vital for photosynthesis. And also high concentration of copper salts have actually long been offered to spray on plants as reliable fungicides (e.g. Bordeaux mixture - copper sulphate and lime). At finest the copper thing may assist to inhibit fungal strike near the wound, which would generally heal through time. Of course the copper could be a difficulty later if the tree is sawn for timber. Ken Joy, (lsrak
csv.warwick.ac.uk) THIS might be true if the piece of copper is the shape and size of a large axe. William Hamlin, Ontario, Canada. During my years as a tree operated doctor I have come throughout the "copper nail" myth countless times. Part years ago, as soon as cutting up the tribe of a commonly vigorous poplar, ns came across a ring the copper nails. Numerous inches within the wood, the tree had enclosed them and also carried on cultivation with no ill effects. Geoff March, Stroud, Glos. TO understand the potential affect of embedding a poece the copper in a tree stems on the long term wellness of the tree, some basic plant physiology and chemistry requirements to it is in considered. In order to death a tree, a toxin should interfere v cell department in the regions from i beg your pardon a tree grows - root and also shoot tips and the cambium, a ring of separating cells inthe stem and roots. In addition, inhibition of a critical process such as photosynthesis will have actually a comparable deleterious effect. Implanting a piece of copper in a tree trunk will only influence such an essential processes if the copper is transported native the implant to the roots and also shoots. There are two courses that copper can take. The an initial is in the xylem, the woody organization that develops the mass of the tree stems (wood) but additionally forms the key transport route for water native the soil, via the root to the leaves. Movement right here is controlled by the price of water loss from the leaf and this process is regulated by stomata on the under surface ar of the leaf. Products move passively v the circulation of water, although those with a confident charge will solve to negative charged sites in the walls of the xylem tissues. The phloem tissue (bark) is extremely specialised and is responsible for transfer of assets of photosynthesis from pipeline to shoots and roots. It deserve to rapidly seal off any kind of injured tissues. Copper from an implant would should dissolve before it might move to roots or shooting and impact plant vitality. The pH of the phloem and xylem sap is contempt acidic (pH 5 - 6) so part copper would gradually dissolve. Copper binds preferentially to the xylem tissue and shows restricted mobility as a cation. That readily forms stable organic complexes with little molecules such together amino acids and appears to relocate through the xylem in this form. This complexes are an extremely stable and also may no dissociate at the end of the carry pathway. If so, these will not conveniently pass throughout biological membranes and inhibit metabolic activity. Copper activity from leaves, via the phloem is very slow therefore the redistribution via this organization from an implant would likewise be slow. The slow rate of copper release from a metallic implant would be i can not qualify to cause significant problems because that a healthy tree. As the key route to living tissue would be via the xylem, the fads of water motion within a tree would likewise be crucial in the succeeding transport of copper. These vary with tree varieties - in part water ascends directly up whilst in others, water activity occurs in a spiral of verying pitch. Numerous implants would be required to make details that all components of the tree crown were reached by copper. In conclusion, ns would take into consideration it unlikely that a single copper implant would prove fatal to a healthy and balanced tree; one old or already debilitated tree might prove come be much more susceptible.

livjm.ac.uk) Well..... That killed it! Mac, shrewsbury uk I had actually a young witch hazel tree in mine garden for part years which to be flourishing, so lot so the I needed to support among the branches. Without really thinking around it, I offered a length of copper piping as a stake near its roots. When I noticed the branch had passed away for some mysterious reason it didn"t happen to me to remove the piping right away. By the time I did the totality tree had actually died. I have left it in the hope it may revive native the bottom (without the piping there obviously) but I"m not positive as it"s usually prospering catkins in January and also so far...nothing. RIP tree. Jane, London UK to ~ Dr.Nicolas, together a researcher in Egypt horticulture institute ns am interested in copper and also its movement in trees. I read your elegant article of copper implant to death trees. I"ll be very glad come tell me about ways to hinder or stop copper indigenous entering or penetrating in tree for research study purposes. With ideal regards Hamdy Elzayat, Cairo Egypt Copper salts and ammonia are effective at dissolve cellulose. This is how viscose and also cello tape are made. Cellulose is the main component of plants. Ns think this is the thinking behind the idea. An prompt cold pack and some plain (no enamel) copper wire in a hole in the tree might work. Paul, columbus USA yes a copper spike into the stems of a sawn turn off tree guarantee no re-growth, to kill the tree that hasn"t been chopped under - usage a knife and cut the bark around the tribe a 2 customs strip totally around... The tree will die. DeeJay, UK add your answer
