Idea - Identifying trees which cause problems
I read recently that you can now have DNA testing done on tree roots to find
out which is blocking your drain. However, I've also tried the experiment where you split the stem of a white carnation in half, putting each half into a glass of coloured water. The carnation gets coloured stripes. Could you do the same with the tree roots and put them in a bucket of strong dye and wait to see which tree turned blue? If the dye isn't strong enough, maybe a bucket of glyphosphate weedkiller so the problem tree and no other would die? It seems sensible and must be cheaper than getting DNA testing done? |

It seems sensible and must be cheaper than getting DNA testing done? Glyphosate isn't taken up by roots as far as I understand. It degrades in soil too. You have to apply it to the green leaves alone to have any chance of killing off any plant. If you could prevent escape into the drains/watercourse applying sodium chlorate or something similar to thr tree roots might be the answer. Even if it just caused enough damage to identify the tree that was causing you problems it might be useful. Dave. |
