Seabreeze brain trust...

Any idea what tree this is?
I think its a variety of "Shademaster" (Gleditsia triacanthos)




Yes... that is a roo jack trying to remove the roots.

Poinciana / Flame tree possibly - does it flower flame red? Could be a Jacaranda??? flowers a beautiful purple. Could be neither as I have no idea what I'm talking about.

nice scale ruler too!

Definitely not jacaranda.
Doesnt go red either.
It does flower (bees love it) but cant remember the colour

I'm leaning toward poinciana too. They can have a range of flower colours, including white, yellow, orange and red. Red is the most common as far as I know, in Aus anyway.

Let me guess, the adjoining property on which the tree sits is an absentee owner who doesn't give a rats poo that the virulent tree drops copious amounts of leaf matter and berry's that clog up your pool filter? When you reach the root system you will be tempted to drill a couple of holes and fill them with round up. The tree will only partially perish, and the remaining branches will become more virulent, particularly the branches that grow over your fence. Just a guess......

^^ cos roundup only works on leaves (kills cholophyll or something s it can't make energy anymore)

copper sulphate around roots more effective.

No that you could do it to somebody else's tree....

The owner is there. (But doesnt seem to give a poo... yet.)

It has thrown up seedlings via suckers a long way from the tree.
Drops loads of small leaves (completely bare in winter)
It took over a garden bed and now that we dug that up, we can see its in the lawn (which never grows properly in that corner) AND now traced roots into the paved area in our alfresco where a few pavers are lifted

I like the tree... don't mind the leaf drop - just not the damage its done.





Its looks very similar to poinciana but the flowers dont look the same.
Really hope its not a robinia pseudoacacia (http://seacliffcoast.com.au/suckers-plague-locusts)

maybe a "sticky gum"?

not really a gum tree but for some reason they were called that

....better than a poke in the eye with a sharp stick?...

Not that you should have to pay for it - although it would be worth asking the neighbour to "help out with associated costs" to save them having to pay for you to redo your entire lawn/paving due to rogue tree roots if you both like the tree?

Thats the route I'm looking at <see what I did there


We dug up the whole garden bed 4 years ago and lined it with plastic to stop the roots from coming over (It was a small tree).
Cut back all the roots that had come around the edge of the limestone blocks - Didnt work obviously. 1 root found its way into the plastic liner and went nuts also encouraged the tree to seek out more under the liner.



Unfortunately its kinda snowballed over the 2 weekends its taken us to pull the roots out - the more we pull out the larger the extend.


I wont need to poison the tree as I'm pretty sure that from the volume of roots we pulled the tree is gonna get real sick anyway.

It might slow it down but it's tougher than you think

Drill a "few" 4-8mm holes into all the roots and branches you can and fill said holes with "Tree and blackberry killer" and not Round Up. All your problems are solved. The more and bigger holes, the quicker it dies but sometimes it's better to play the long game so your neighbour doesn't realise what your up to Bit suss if he's heard you digging and a few days later his tree is clearly dieing.

If you can't find any, PM me and i'll get you some.

Looks like Poinciana to me.......I had one hanging from a neighbour's garden onto my property. He wasn't interested about my gutters getting blocked up and it dropping ** everywhere so I totally pruned all the limbs hanging over my side for a couple of years. The tree got very lop-sided on his side and eventually blew over in a storm....damaging his garage and his car.






Good luck!
Oh, by the way I agree with the above comment from MDSXR6T's technique.
Round Up WILL kill most things. I've used it on tree stumps that keep re-shooting. Drill a 3/8" hole about 1" deep into the stump in 2 or 3 places, pour in Round Up and block hole with chewing gum ( sugar free naturally) to stop rain water diluting it. It'll die.

We went through this with a fig. Council solved our problem. Have you called them out?

Your neighbor is liable for damage caused in QLD law. WA??

Fwiw looks like raintree.

Not got council involved yet. In WA, neighbour is liable for damage.
Prefer to resolve peacefully but so far its been "do what like on your side of the fence - not my problem"
Still go to chat to another neighbour that backs onto it was well.
Pretty sure its gonna have to come out... just need to go through the correct motions. (Got the advice docs from Legal Aid and Council)
Will have to obtain a Arboriculturalist Report. (Which I have to pay for. Waiting on call backs)



At the moment I need the tree type to see if it was a suitable planting in the first place. Get some info - forewarned is forarmed?


So far the Peltophorum pterocarpum Yellow Poinciana looks the closest (but doesnt have thorns - which is why I thought Shademaster/Honey Locust?)
If its the Poiciana... "Even though Yellow Poinciana will develop a very large trunk, its shallow, surface roots make it susceptible to being blown over during a hurricane's severe windstorms. Locate the tree about ten feet from sidewalks or pavement so the large surface roots don't cause damage."

Its about 30cm from the corner of the block...




Thanks for some pointers guy

Undiluted Roundup directly into the roots, or even into the trunk works. I've tried it on some elm trees that were sending suckers everywhere.

MDSXR6T is correct.

""Tree and blackberry killer" and not Round Up"

re the woody tree killer .mix with diesel and paint onto exposed roots. bruise the roots first and expose for at least 200mm . once painted wrap the root in gladwrap. THE END. the diesel used to be mentioned in the instructions. drilling holes in trunks works by accident as you are drilling into wood that is no longer part of the active part of the tree. it is fine if you introducing a mold or fungus to rot out the stump

Edit: beaten above!

Mix 250ml (Richgro's version is $18ish) with about a litre of kero (or diesel from memory) and that tree is dieing before you even get a call back

Can also paint it on but it's more obvious. Subtle holes so neighbour has NFI. Or wake him up with the chainsaw at 7am on a sunday!!

you will find that it is a Jacaranda .

With respect Mark - as I generally enjoy your posts- ahem bull dust

Glysophates ( such as roundup) will work as a foliar spray on woody weeds, grasses and shrubs - but on established trees it best works as basal injection
As others have said drill into the cambium layer of the trunk - do not drill deeply - the outer layers is where you need to inject poison of choice

If you can't do this then do the same to the roots you have access too as per landyacht- just make sure you expose that cambium layer for best results

Its a poinciana btw

+1 Poinciana

Those things are an invasive weed on Christmas Island.

Poison it.

Uh well there ya go
tried roundup in trunk, seems I can't even kill a tree lol

Trick for young players - or old ones

Once the wound - axe, drill, shovel, whatever - is made in the outer layers apply poison immediately - otherwise the cells close off and do not draw in the poison and transmit to the roots

Do not have a beer between making the cut and applying the poison

Poisoning of trees is best done in autumn when the phloem is returning to the roots

Copper nails all over, and then epsom salts in a large hole that is sealed to stop rain rinsing it out.

yeah its a Poinciana and if it makes half as much mess as my neighbours Jacarander get rid of it,Ive either got leaves covering my deck or flowers depending on time of year-out with the round up with a bit of pulse to speed things up a bit

you will find that it is a Jacaranda .


so tell me brains trust why don't you think its a Jacaranda ?


the original poster recons he couldn't remember what coloured flowers it has , so that leaves it pretty open to guessing imo

the seed pod is def not a jacaranda. Jacs dont send out root suckers just shoots from the base when disturbed
+1 poincianna

ok, so there may be a very slim chance that i am wrong , again . You do sound fairly sure of your self . So i am tending towards believing you .

Found an old photo of it - yellow flowers. Which still doesn't narrow it down as Poinciana and jacaranda both have yellow varieties.

Went to a garden centre and they weren't 100% either.
Waiting on a guy (Arborculturist) to come out to ID it and give the neighbours some options. Also a report for if it gets... awkward.

Its already looking a bit droopy. No poison so far.

Id's are often difficult from photos - but its not a Jacaranda - sorry Sands - seed pods on leaf structure a dead giveaway ( my brains trust - Whilst I come from a civil background I have 15 years exp in managing tree contracts / cert 3 arb yada yada yada....)

Good luck rod....In my experience Councils vary wildly in Tree Policies and their applications -
