The Tree and BlackBerry Poison which contains 50g/l Trichlopyr from Bunnings did not work. I need a effective one to kill a big Amla (Emblica officinalis) tree. The trunk is now 16 inches across.

Hi John, thnx for reply. What is Neat Roundup? Is it the undiluted weed poison that you cna buy from KMart and Woolies?

The trunk of Amla is so hard that drill can't drill in. Hammered a chisel in and it broke. I now use a nail punch to make a shallow hole. Debark it to 1 foot above the ground. Smear that Bunning's tree poison for a few days. The tree still going strong 3 weeks later. Now I spotted some flowers. Will wait to see if it set fruits because I want some seeds.

Has anyone use Sulphuric acid? How do you kill a medium size tree of 1 foot wide trunk? Do you drill a hole and pour in the Sulphuric acid or wound the trunk with saw cut and smear?

For the 60ft tall tree, how high was the hole from the base of the trunk? Does the hole has to be very close to the ground? How deep is the hole?

I put 4 holes about 500 mm up from the base, solely as it was easy to reach, they holes were about 100mm deep.

The tree died from the top down in a matter of weeks.

Please help - our neighbour has a 60 foot high x 25 foot wide cypress tree planted right on the fence boundary. The roots have invaded and lifted our pavers heading for water and foundations. We have pleaded with them offered to pay half, to no avail. We have just lifted pavers and dug up soil to find large roots running through our property.
My question is: We could cut the roots but that probably wont damage the tree and they will grow again. We woiuld like to use a poison, say Roudup, but wonder if this can be detected by our neightbours?
Any help or info would be greatly appreciated.

Hello Pearl
You are in a difficult situation for sure and the best way is to mediate, but, as you say, they are not about to come to the party.

I have killed trees who's' roots have invaded my soakage trench with liquid chlorine but considering that they are aware of your concern, you will get the blame if it dies from whatever cause.

Here's a couple of ideas

If you are on talking terms, explain that the roots are doing structual damage and that would it be OK to cut them back on your side of the fence.

If you don't speak, write to, or go see the Council and explain the situation to them and see what they say.

Get a solicitor to write to them explaining that their tree is causing structual damage to your property and that they will be held liable.

Get a tradesman to repair the pavers and give them the bill. If they don't pay take them to the small claims court which will cost you very little, just the cost of typing the letter here in QLD

So. I recommend you do not kill the tree --- just yet

The trick is to fill the hole immediately after drilling, so an airlock does not develop.

I drill a 6mm hole and keep a pre filled syringe (100ml horse size), keep
topping up the hole til the tree stops sucking.

Hi Guys,
A good tree killer to use, 'Access' & diesel! Just mix 17ml of Access with 1 litre of diesel, spray the trunk of the doomed tree, say 1 metre up to the ground, and that's it. For guava trees, just double the strength (or spray it twice, or both:-)

Mind you, the last time I bought Access, it was $100 for 1 litre :-(

Only problem, you can smell the diesel for days :-(

Diesel is also great for killing big ant nests (like bull ants!) and biodegradable too! Cheaper than poisons in the long run.
Pour it carefully down the holes - as much as possible (my big nests take 10-20L) come back in a few hours - if the ants are taking out all the eggs then it's worked. Squish the eggs (a bull ant nest = a 2L ice cream container worth!) The ants will not re-nest there cos of the diesel - and hopefully you have dealt the colony such a blow it doesn't recover/move. :-)

if i were you and didnt want to cause too many problems with your neighbours, look into installing root barrier along your fenceline. it will demage the tree, but it will kill the roots on your side and ensure it from growing into your yard again, instalation cost is usually worked on about $80 a metre, it will demage the tree but it usually comes with a guarantee that it can not be penetrated for years. it can usually be installed anywhere within a about half a metre of a fenceline. if you poisoned the tree and they got an arborist in to test the tree, the arborist would confirm the tree had been poisoned, see you guys have already approached them, it owuld be easy to conclude that you guys had poisoned it.

Thanks for your great advice. Dont really want to poison the tree - its just not fair to have your sunlight blocked and pavers lifting to such an extent - I wish they would just do the right thing and remove it.
Thanks again

I have been trying to poison, dig up, just anything at all - a mexican coral creeper and a plumbago. I have used blackberry poison and roundup concentrate and also in desparation, neat kerosene. The kero smells but is effective to a certain extent but the coral vine always grows back. This has been ongoing for 2 years now. Any hints please?

Psycloud says...
Well, I had a cousin who had some Oleanders in her yards that she wanted to get rid of, and she chopped them all down and used a mulch machine and turned them all into mulch, and then she placed the mulch around all of the oak trees in her yard (these oak trees were all about 40 or 50 foot tall, maybe larger) and all the oak trees in her yard died. Unfortunately she learned the hard way that oleanders are poisonous, maybe you could buy an oleander and mulch it and put it around your mexican coral creep and plumbago.

It might seem crazy, but if it can kill very large oak trees, I think it might be able to kill that, but I can't be positive.

Cheers

Wow psycloud, I was thinking of planting a persimmon tree in the spot where we used to have our large oleander. We got rid of it like your cousin...not sure but i reckon the silly gardener who did the job did not remove all the roots in the soil.

So i reckon it is not safe to plant anything at that spot??

There was a tree case in NSW late last year where the next door neighbours tree did a lot of damage to their sewerage pipes in their backyard so they took their next door neighbour to court and wone the case so that case now changes the law about tree roots, if you inform your neighbour of the problem with a letter and date it and keep a copy and if their tree roots damage your properity you are able to take them to court for the damages.

Would this apply to all states, or only NSW? My neighbour's five Eucalyptus grandis tree roots have completely taken over my garden and pond.

I don't like the thought of getting involved in a court case though. All he would have to do to fix the problem would be to deep rip along the drive.

Maybe I'll try again - last time I spoke to them (tactfully and politely)the response was 'They're not causing US a problem'!

Hi Julie,
How about having a 'trench digger' dig a decent trench on YOUR side the fence and place a 'tree root barrier' in the trench.
That should solve your problem :-)

Jimmy, yes, they shade all my fruit trees and veggie garden from midday on. But I am not on solid rock - each block varies. I have plenty of medium sized rocks, but mostly gravelly soil. The old guy who built the house seems to have removed most of the rocks and built walls with them.

Brendan, I did exactly that a few years ago - cost me heaps. The effect lasted about a year, then I guess the roots went under the barrier. Very frustrating! A deep ripper on their side wouldn't kill the trees, though it may have to be done every couple of years. Orchardists round here do it all the time when they are surounded with natural bush.

Hi Julie,
Another way to make the tree look like it's died from phytophthora root rot, is to find and cut the roots off (on your side), and wrap a rag around the cut off root(s), soak the rag in neat roundup, then place a can over the rag, then fill the hole(s) back in.

I'd say it's highly illegal though, tough decision you have. Surely the owner of the offending trees can see the damage they're doing at your place. Makes me cranky when people are like that.

Sorry folks, but if you use any petrochemicals like diesel its gonna be there for LIFE so the soil would be useless for anything else unless you replace the lot. There is a new very powerful Roundup available but I hate supporting Monsanto ( they own Yates seeds as well). There are many other glysophate products available & cheaper too!

Ive killed hundreds of trees as a bush re-generator - its very easy with the right technique.

Best way to kill trees is with pure roundup, a hammer and a chisel. Chisel around the base of the tree leaving a gap (width of chisel)between the next chisel mark. I chisel 3 holes about a 2cm deep into the tree, then fill all three holes with poison, and repeat this until i have gone all around the base. Leaving a gap is important, as is not waiting too long before filling the chisel holes with poison. If you do this you are guaranteed of success.

I don't know who owns yates but roundup is a monsanto product distributed by yates for monsanto :), they don't make the stuff, only sell it.

I used roundup once around my trees to see if they would grow faster with no grass.... It certainly killed the grass but the trees didn't seem to like it either and didn't grow well that year, worst of all I didn't see a Victorian tree frog for about 3 years when before that they were in every tree.

Everythings come back to normal and the frogs are back (not as many as before) 5 or so years later but it's certainly not a good thing to go and I only used it the once :S most of these subtropical trees have roots basically at the surface and I really think the roundup hit them as well as the grass

Hey John Mc, I see you want Yacon on your wish list. Been growing it for years and find it great. It is NOT however, as sweet as apples as you believe in your Edibles page. Very crispy indeed, and contain a sugar called inulin. Best used as a water chestnut type texture in stir fries, or refrigerated and eaten cold (very juicy and crisp). Have to peel, as the peel is tart like it contains tannins.
Sounds like you want to lay out a red carpet because someone is famous.....

Hey John Mc,
I use the vigerous tops for a high protein green feed for my meat goats in Summer when the grass is brown and they need the vitamin E. There is a bit of a side effect of the inulin that the tubers contain. The body apparently does not make an enzyme to digest it, so it goes through the body undigested. Apparently this is good for diabetics since it does not give a glucose spike. The drawback is that it gives everyone I know one hell of a case of the wind! I use the tubers mostly as a refreshing crispy, juicy snack in the garden. They grow under such tension, that upon lifting, they split, which makes them spoil if you try to store them. I just leave them in the ground until needed, and then "bandicoot" the tubers out as I need them.

That's a goodireah. I still have a clump I haven't lifted as yet. The clump must end up huuuge if you don't lift them for a couple of years. It's good to know it'll always be there if you want it. I like the set and forget plants, and bonus, it appears the rabbits don't like the foliage so far. They cleaned up all the excess tubers I left lying on the ground.

Access is the diesel formulation of triclopyre and picloram and is particularly good for getting rid of trees, especially since you only have to paint the bottom foot or so of the tree trunk. Grazon Extra is the same actives in a water formulation that can be sprayed onto foliage with the same result. Have never known these chemicals to fail at killing trees.

Hi Lorna,
We have something over her locals call Male Guava. Looks like a normal guava tree, but never bears fruit.
Apparently, it's become a huge pest tree in Vanuatu.
Anyway, Access & diesel works a treat here, just have to increase the dose, or, spray it twice :-) They are very hard to kill.
When 'suckers' start growing from the roots (they always do with guava), I cut 'em in half and spray them :-)

We had a 10m gum in our front yard which had to go . I raised a turf flap & then dug down about 300mm to a horizontal root which was some 10cm thick . Then chiselled out a boat shaped cavity in this root and poured in 30% diluted roundup , placed a plastic bag over the root cavity ( to keep it clean) then soil and the turf flap . Went back a to topup each 3 weeks until the tree began to dry out and die .Tordon is better but not available in NSW.

Bob, why did you dilute the Roundup? I would have thought you could use it neat in a case like this.

Have tried both undiluted Roundup and 25% dilution in the past. I must say the diluted works better. The trick is to apply it AS SOON AS the wound/cut is made.

Does anyone know if HCL (Hydrochloric acic) goes off after a time. I have a bootle bought 5 years ago. In the past up to 2 years ago, when I used it the acid on the tree, I can see vapour and smell the burning. But today I used it, no smell, no vapour.

Glyphosate is an interesting chemical. It degrades once it's comes into contact with soil - as a tree killer it's not the best option unless u are very pendantic with re-application. Using it neat is just a waste and overkill - there is a reason for the dilution rates after all.
It works poorly on plants that are not actively growing, have a deep root system, corms, or are dirty/dusty - amoung other limiting factors. You can't use any old wetting agent with it either...

I think its a shame that it is abused/over used and now under threat with "round-up ready" canola... I use it a very last resort - it's the 'most evil' chemical I own (besides a can of fly spray - which lasts me about 2yrs! lol) Weeds are becoming resistant to it now...so what's next?
I would prefer the HCl too fruitist...but there are other ways to kill trees too. I don't think your bottle will go off in a hurry if it's sealed properly/tightly...what else can it change into other than gasses..?

The only effective way to kill a tree is to hire a tow truck to pull it out. I pulled out a large Amla, Cauplin Cherry and a Mandarin. Longan, Kwai Muk, Persimmon, Canistel, Chermioya (fina de jeta), Guava are hardest to kill. Suckers keeps growing up at the base of Longan trunk even using Roundup and HCL for 12 years. Persimmon and Guava have suckers from roots at a fair distance from the trunk. 25% dilution is effective with one application on Mata Kuching (a type of Longan) and Acerola Cherry, all large trees with 9 inch diameter trunk.

I have used the blackberry and tree killer for evil regrettably.It doesn't take half a bottle to kill a big tree.I put a stray large root 'on the drip' and the large weedy tree died suddenly 2 months later.Drill 4 to 5 holes around the trunk and squirt in imeediately as you go.Some species are knocked back quickly,some get sick and grow through it but never come good and some need repeated doses to take them out.Root 'flashing' to other trees apparently is rare.The level of collateral threat from the volumes used is minor and even glyphosate and all commercial surfactants are not benign.

I also want to take out a large Lacoocha, a Spondias purpurea, a Brysonima babilosa, a purple skin Starapple (since I also have a large fruit green skin variety) and a Japanese Plum (meals on wheel for bats) all around 15ft to 20ft tall. Lacoocha had a stay of execution last year because a club in South Australia wanted seeds. I sent Kwai Muk seeds (sourced from Mt Cootha Botanic Garden that has larger fruits than Lacoocha) to that club but I didn't get any thanks. One Kwai Muk fruit I picked from the ground has 25 seeds in it. See the enclosed picture.

The Kwai Muk is one of the hardests to kill due to its deep deep tap root. I drilled 6 holes into the base and been pippeting undiluted and diluted Roundup about 6 times over 3 months into those holes. Still, the uncut branches have masses of flushes coming out of fallen leaf node. Yesterday I tried the HCL. If it does't die, I will use the blackberry and tree killer.

Roundup doesn't work well on some species and when drilled/injected.Drill 4 or more deep holes around the trunk and top up a couple of times.

The Kwai Muk without its crown. See all the new green growths on the Kwai Muk branches. KJ Pink aka Paxton Prolific is in a deadly embrace with the Kwai Muk at the front. White trunk on the left next to the pot is a Taiuva (Maclura tinctoria).

My latest find:

Go to Bunnings and buy a "hortex" sprayer, it fits on the end of your hose.

Remove the diffuser from the end, it then send a jet of spray up to 20 feet in the air. Set the dial to "10' and it puts 30ml chemical per litre of water that comes out. if you pour roundup straight from the bottle into the machine it makes a very powerful whole of tree killer.

Hi.

Does the Neat Roundup solution work for all or most trees? I have a huge tree and I do not know what it is called. It has a black/green bark with a +/- 40 cm/16 inch diameter. The height is over 7 meters. The fruit are small seeds/pellets that turn to a yellow colour when ripe. Nothing much grows around the tree - it seems to destroy most of other vegetation except for weeds.

I would like to try the Neat Roundup but I need to know if there is hope that it will work.

Is it illegal to poison and kill a tree? We have 3 big gum trees in our garden. We want to cut them down as it's very dangerous for our two young kids when the really big branches fall down. It happened 3 times already and it was lucky that all of us were inside the house. We think about asking permission from council to cut down the tress. Maybe they will say NO :(.

Every council in Sydney has rules about tree removal; best to check - but yes, maybe they will say NO, especially if they're natives, though our council (North Sydney) says a tree is a tree and does not have separate rules. The bigger the tree the harder it is to get permission for removal but if they are dangerous you may have a chance.

Bunnings tree and blackberry killer is pretty effective and easily available but it is expensive.Stray roots from overhanging neighbours trees have allowed me control and given extra leaf mulch.Glochidion,jacaranda,laurels and bleeding heart as well as stumps of underperforming trees in my yard have been controlled with the stuff.

curry killer says...
I have a curry tree which has caused extreme damage to my drains, concrete and paths. I cut it back and drilled holes in base and side and thought had successfully killed it with diesel and kerosene. However it continues to send up suckers which I constantly poison. I have removed all the brick paving and begun to dig up what roots I can access, cutting them from the main tree root, drilling holes and painting/filling with blackberry poison. I am now in the process of cutting down the stump further and starting again. Can anyone tell me even thought the stump appears dead and I have severed more of the roots, do the severed roots further along respout suckers?

for those with tree problems, mix roundup at about double strength or more, dig up a root , cur it and put the clean cut into a container of the mix. The root doesn't need to be big but the tree will suck the roundup right through its system. It even works on umbrella trees.

Payo, thank you for advice. Do you keep the root in the mixture for awhile? Mine are very tight as they are going under the concrete and I find it very hard to lift them as they are deep in the soil.
I have just discovered the answer to my question regarding do the severed roots re sucker. YES! they do! After all the rain we have had in Brisbane, there are little green shoots everywhere and I have been now applying the concentrated Roundup, with diesel& Kerosene plus nother Tree killer. Sounds like over kill but that is what I want. Waiting results of this attempt which I have done today. Curry Killer.

There are heavy fines & gaol sentences for repeat offenders. Let's hope you don't have any children you miss seeing once we procedure you.

haha some people have too much time on their hands. First of all, cutting/killing a tree is governed by local Council, not by State or Federal Laws. I've worked in local Councils in NSW and can't tell you how many trees have dissapeared. Without proof no one can do anything. It's very hard (time consuming and costly) to prove a tree has been illegally lopped.
of course im referring to YOUR OWN TREES and not a neighbors or ones on public property - if you kill these you deserve to be punished.

i want to selectively cut tree roots that are likely to become a problem . i intend to poison those roots and to apply the poison to one side of the cut in essence leaving the main trunk unaffected leaving a gap between the cut of about 3inches.
i want to keep the tree as is as much as its possible. Is there any opossibility that in doing so the poison will impact both on the roots i have cut and some how on the tree its self. i intend to maintain the tree.

ponty, rather than using a poison that will kill the tree, use copper sulphate on the roots when they are exposed.

I did this with a large Paulownia that had roots blocking the drain. Seems OK so far, and I have poured copper down the drain so the pipes are coated - that should discourage any roots in future.

thanks for the comment. i guess my question relates to the situation where i cut the root so that it does not form part of the trees system and poison only that part. My concern is that in the process although i have only applied the poison to a selected part it gets into roots that i cannot see which may be under the ground

Thx Sternus.
I also read something about hack and squirt technique, making cuts around the bark with a saw or ax and injecting it with glyphosate.
I have a big birch tree in my yard which is giving me headaches with it leaves and catkins dropping during March and November ! I can't remove it from the council because it is 25 years or older.
I thought of drilling holes around the bark but they will notice it. Is there a way to cover up these holes or cuts I made with an ax?

Last week I did a test on a bush in my backyard with a branch, roughly 5-6 cm thick. Made some small holes in it (1cm deep), put my ax in it and poured the glysophate. Around 1-2 ml per cut.
The time between cutting and pouring was less than a minute.
Now almost a week later I don't see much happening with this tree branch. All the leaves are still green. How much time should I wait before noticing the decline of this branch or tree?

For Glypho there are many variables, it depends on how fast the sap is flowing. The weather should be dry and warm and the subject should be in several hours of sunshine to be effective. Small weeds can take up to a week to show signs of leaf yellowing in ideal conditions.
There is a new weed killer on the market based on pine oil, suppose to work a lot faster, noticeable results in 24 hours, so the adds tell us, but I have no experience with it.

Update:
After almost 2 weeks, my branch lost 50% of his leaves. First they started to shrink and change colour before falling off.
Any idea how long it will take for the whole branch to die?
Is there still a chance that new leaves will grow on this branch next spring?

John, I was given a sample of the pine oil weed killer some time ago. It works best on broadleaf weeds and grasses, no good for bulbous plants like oxalis. Doubt if it would work on trees.

We only have access to the roots, which are about a foot around. Can we drill and poison this way?

Yes works surprisingly well with concentrated roundup. Drill half a dozen approx 5mm diameter holes {mabye bigger if tree is huge?) in all roots available during day when tree is sucking up water from roots. Fill holes with large syringe and large bore needle immediately to avoid an air lock. The tree will suck hole dry so keep holes topped up. If holes suck air it creates an airlock and decreases suction. Keep topping up for at least half an hour. There is no reason why one can not finish one root and then do another or drill a new holes the next day to make sure if tree is big.

using a tiny 2mm drill (no one will find those holes) drill in for about 5 cm at 45degrees. for a really large tree drill deeper .Use a syringe to,inject neat herbicide like round up. Repeat after one week if you can find the holes again. About 3 to 4 holes close to the ground will do. Works a treat the tree will be dead in 3 weeks.

My experience with using glyphosate on trees was very different. The trees were large so I used an axe to cut and immediately poured the herbicide in. I had to keep repeating the exercise every couple of weeks for several months before the trees showed signs they were going to die. Later for some other larger trees I again used an axe but the herbicide was garlon. The trees were dead after about a week with only one application.

garlon. that's a new one on me. apparently it is triclopyr and it is specific for woody plants. maybe good for trees because of that. not good for pines, apparently, though.

i'll try it. glyphosate has failed to kill the thing I'm trying to kill. I've bored holes and repeatedly poured neat glyph in them, I've uncovered roots and put holes in them and repeatedly put neat glypho in them... the tree is still filling my gutters with seeds and leave....

Better life some where not here says...
Huge trees alongside my outside fence line. Have been told some type of wattle, not the pretty yellow flowers. They have killed my lawn,fallen leaves up to my ankles. I took photos to fire brigade as branches close to my power line, just need a big storm @ wind,or a fire @ my house is gone. Am afraid nothing will be done because of who my neighbour is. My daughter did Horticulture @ said they will kill the garden becauze they poison the surrounding area. Sorry wish I knew how to send photos

If you want to kill a tree the easiest way to do that would be to drill several holes in the tree (say 6mm) and pour pure glyphosate weedkiller into each hole.

You have to be quick though as apparently the holes close up quite quickly. So drill a hole and straight after pour the weedkiller into it.

Hi John we have a huge leopard tree on Neighbour's property. House has been rented for years and all renters and us hate it because of the mess it drops as in seed pod, flowers, tiny seeds that I have to keep pulling out. Landlords won't do anything about it as too costly. I have never killed a tree or anything in that matter in my life but it is making our gutters rot and the whole of the drive is just covered with leaves etc. it is a nuscience of a tree. The renters want to get rid of it too. Can you tell me where to drill the holes and I have read about the roundup. Also will it just die from bottom to head. This is why my husband hasb been so reluctant to poison it as he is worried it will fall on our home. Any advice from all appreciated. Please do not send inflammatory remarks to my question other members

Golden Cypress says...
In my case, my Golden Cypress has been poisoned. A beautiful tree and in the center of my front garden so it's of no inconvenience to anyone at all. I've become aware who the culprit is and at this stage of ongoing investigations into other matters, I'll only be pressing charges at a later stage. In the meantime though, the tree is dying but not completely dead yet. Does anyone know what I might feed the roots to be able to counteract Roundup? Albeit, I'd always suspected a different defoliant had been used, same as had been used in Vietnam, whatever that may have been.(perhaps Roundup?) My reasoning the tree has not died, is that whatever poison has been used was only watered around the tree's base and "e;fortunately"e; no holes drilled into trunk etc. I'd really HATE to lose the tree. But she really has deteriorated substantially.

How do you know it has been poisoned?. The photos show nothing wrong with the tree. The dead leaves are only old ones, and leaves dont last forever.
