I have a large shrub with a tree growing up through it?

I have what I believe to be a shrub which is seven foot high and has started to flower. I live in the west country (UK) It produces a mass of yellow flowers each year that look a little like Heliopsis. They are not heliopsis because they are small, 3/4 of an inch across. It is a quite common plant.





Growing up through this shrub is a tree. Because I try and cut the tree back each year it sends out several branches making it grow like a shrub as well. I don't know the name of either.





The tree is very vigorous and although I have tried to remove it completely it keeps coming back as the roots seem to go a long way and it is impossible to remove them all without destroying the yellow flowering shrub it is growing up through.





Is there a method or a product I can use to poison the unwanted tree without harming the flowering shrub?





Many thanks in advance for any answers.

If the shrub flowers without leaves in Spring its probably a forsythia, if it has leaves and flowers later its probably a rose of sharon (st John's Wort). Either way new plants are very cheap you can often get them in supermarkets for a couple of pounds. The tree sounds like ash (stalks are very 'bendy'). They are a devil to get rid of. You could plant a dense shrub like Choisya or hebe which will block the light to the tree and slow growth to a manageable level, otherwise you will have to poison it. SBK works well (stump and brushwood killer).
Reply:buy as new shrub or grow another
Reply:Your shrub could be Rose of Sharon and invasive tree,an ash as these tend to pop up all over the place. I get the same problem but i just cut off at ground level if they won't pull out as i don't like using poisons................
Reply:sounds like youve got an ash problwm cut it down as low as possible make some holes in the stump and use a chemical called root out or deep root these contain ammonium sulphamate wich will kill the root bee carefull not to spill any it kills just about anything it comes in a crystal form pop it on the stump then cover with a bit of plastic
Reply:It sounds like you have a member of the Forsythia family as your shrub. I've put a web page in the source block below with various pictures of yellow blooming shrubs for you to look over.





The second source addresses killing a tree without chemicals. It's do-able, but takes time. Another way to address the problem is by cutting it down and using a stump removal process - naturally accelerated or chemically accellerated. (Second web page sited) If you're of a mind to use chemicals, than you may want to consider using a glyphosate, but please read up on them before using. (Third web page sited)





Best of Luck to You.
Reply:are you able to cut the trunk of the tree at the base?


like a foot or less from the ground? I'd think that would


take care of it (think of when they cut a tree down and just


leave the stump. (the tree doesn't grow back.)





you might have to de leaf the shrub in the low area when you


are wanting to cut the tree trunk . (chainsaw)


and then I'd just clip the branches and pull them out individually.





sounds tricky, good luck
Reply:chop the tree down as far as you can go,then either use a 'tree stump killer'or if you dont want to use chemicals, drill some holes through the stump and fill them with salt, or again drill holes and criss cross marks and make very wet, so that the stump will rot.
Reply:Maybe forsythia?

I would probably dig up both of them (digging and chopping at the roots after cutting the tree down) using a maddox (double headed axe). You have to be careful not to bounce it off a wall or fence and hit your head with the other end of the axe though.





You could then maybe separate some of the bush from the tree roots and re-plant it someplace else for awhile and then put a big bunch of rock salt in the hole to kill off the tree roots.





Or you could buy a new bush or take a cutting with rooting hormone and try to grow a new bush.





Or else cut the tree down to a stump and put weed killer on the stump or keep painting it with a salt solution to kill it by dehydration, but then the roots could come back up at a distance underground.
Reply:The main stem and the above soil growth of the unwanted tree can be killed by ring-barking,as follows.


Using a sharp knife,carefully remove a strip of bark 25-50mm completely encircling the tree.


Make the cut as near to ground level as possible,ensure that the clean white wood is exposed.


This will interrupt the flow of sap,feeding the tree and all the plant above the cut will die off.


Note that the roots will still persist and may,in time,throw up suckers.
Reply:Cut the tree at its base and use a cut vine and stump killer on it. This is available at most nurseries and works extremely well. You just put a few drops on the exposed cut surface of the stump. Its possible that the plant might sucker and put up another shoot or two, but just do the same thing to those.





I use it all the time in my yard with great results. The stuff I have is red and contains something called triclopyr.
