Evening All
I need some advice on what to use and how to get rid of some weeds and bushes,
See attached pictures
I've tried ROUNDUP and ROOTKILL but without success
Cheers

Hmm.
Farmers round here use roundup to kill ANYTHING unwanted growing in fields before planting crops and used according to instructions SHOULD kill most things. Only exception I know of is bracken. Its exactly the same stuff they get as what we can get in garden centres, just in larger containers and much cheaper in their larger quantities.
One problem is that it is no longer possible to buy stuff that stays in the soil for any period of time killing plants off as that is deemed non environmentally friendly. Consequently all herbisides now enter the plants via actively growing leaves and work their way down to the roots rather than poisioning the soil.
Many plants however will not tolerate regular close mowing ie. hack it down - clear the ground and when it starts to grow back mow it back down to within an inch or 2 of the ground BEFORE it has got big enough to put energy back into the root system. Once every couple of weeks is plenty - when you already have the mower / strimmer out cutting the lawn.
Combine that with a couple of doses of roundup about a month apart and pulling up stubborn shoots of plants line bramble really should take care of just about anything.
Another way, once you have cleared the ground is to dig it over then put weed killer on any weed shoots that come up.
I'm not seeing any unusual plants in your pictures that should not be taken care of by the above.
All depends of how much of a hurry you are in and how much effort you are prepared to put in I guess.
Also clear ground will always be colonised pretty quickly by new weeds so once its clear plant some plants - bushes, grass, whatever it is you want to do with the area to compete with any new weeds attempting to colonise the area.

you need to apply when the plant is actively growing during the spring to autumn your picture are taken in the winter where growth will be close to nill

ROUNDUP it is then by the sound of it.
Especially as B&Q no longer sell Napalm ??
Thanks mikew

The first and third pics, look like plants with quite a lot of soft growth. So as said before, it should respond to a strong mix of round-up in the growing season. It may take several applications.

The second pic looks like brambles. For these you will need a brush wood killer like SBK. But it will help speed the process if you try and dig out as many roots as you can.

It won't be a quick process, but it's better to take your time and get rid of them properly. But it could be worse. Half my allotment spent 4 years under off-cuts of carpet to get rid of the mares-tails! ( Horse-tail )..one of the worst weeds you can get ( except Japanese knot weed )

Looked like my old back garden.
This is NOT for the faint heart'd.
The bramble, (as above) will take some time to 'destroy'.
As i knew i wasn't able to use the bed for my veggies for 2 seasons, i did it harsh.
This wont just kill the problem, it will give you nothing for 2 years -so you will need to re introduce nutrience back to the bed.
Spring is best to start the process (after the last frost).
After cutting down what you can, wait a few days, and make sure there is fresh growth. This way you know they will take it up.
1) Old engine oil (must be old). It is very viscous and takes time to layer down. Due to the viscousity of the oil, the weed wil take up what it can. This causes the growth to slow to a dead snails pace.
2) Wait until it 'looks' like death is on the way.
3) Mix up a strong amount of caustic soda (using all ppe required), and 'water' the bed.
4) Wait a week, and then just pull it all out or burn it.
5) Dont worry about dropped seeds, as they wont be able to grow, due to the oil in the soil.

It is drastic, but works.
