Your top ten worst weeds.

Have a look at this about 'ivy desert.' It was a plague in the PNW; there was a group called the "No Ivy League" who removed it as part of forest restoration. Now, the difference there, is it took over tall trees and pulled them down. Not so many of those in Ireland.

Nothing lived under it. No insects, worms, nothing. I know people like it growing on the walls of their homes, but eventually it pulls those down, too and does give things you want (hello, mice) a nice ropeladder for climbing in.

Vile stuff, we don't have it here so I didn't add it to my least favorite weeds list but it'd have been near the top if we did.

Willowherb, gorse, scarlet pimpernel, thistles. Some day, the willowherb will devour us all here, it's bloody everywhere :(

I have a front boundary wall which was originally a country stone wall against a bank. It has to be demolished and rebuilt as it is now a heap of stones that meanders across the front absolutely infested with ivy, with the occasional very substantial lonicera nitida bush well established and every other kind of bramble and weed growing out of it. A very skilled local stone wall builder has agreed to rebuild it but I will dismantle it. Its going to be some job! Meanwhile I have ordered a few traffic cones to hopefully give a bit of protection from the passing traffic.

Blackberries are breaking my heart, a neighbours garden is totally overrunning with them. Both myself and neighbour on other side are finding it a constant battle to control them. I have a small hand shears inside my front door in case these thorns extend over my boundary and on to the footpath outside my house. Any advice very welcome.

Goodness that's a very sad post. Yes weeds invade. Plant shrubs (except you have pulled yours up) then thickly mulch under them. Pull the few weeds that do come through as they come and re-mulch in 12 months. Eventually the shrubs will get big enough to shade out most of the weeds and all you will need is a bit of regular maintenance.

Using glycophosphate (super weed-killer) out of season or on closely strimmed growth is pointless. You need to understand how it works. Nettles are one of the easiest weeds to pull up, and are a sign that you have good, fertile soil.

Trying to maintain bare earth is a bit of a pointless battle. In the end you will have to pave or concrete but that is hardly a topic for a gardening forum. Do be careful you don't set yourself up for a flooded yard.

I hate bindweed. Mares tails too and (self inflicted) mint.

Tutsan is next on the list to reduce the amount in the garden, seems to spread a lot, so need to stop it from getting too far and becoming an issue.

That's interesting, I didn't know it had a common name, I always know it as hypericum. We have quite a bit of it but I don't mind it too much, some gets pulled up but some is allowed to stay.

Ha! I have GIANT WEEDS!!! Winner winner chicken dinner.

Chives are spreading out of control in my veg beds and on to the paths, will have to take measures to get rid of them before I plant crops again after a few years of no planting.

Elderflower cordial is lovely, my favourite for a flavoured drink. You would really have to be not paying attention though to mix up elderflower with hemlock or hogweed!

Rhododendrons as weeds is a new one. Yes, exotic invasive. Spectacular plants though and not the fastest growing.

They are weeds in boggy soil in Connemara. :D but i hear ya :D
