What is your most problematic weed you find?

First off I would like to mention that I think that some weeds are great. For example forget me nots that spring up everywhere in my garden which my solitary bees love. However one weed that has been the most annoying is enchanter's nightshade. It is a woodland plant and it thrives in the damp shady borders in my garden and it spreads EVERYWHERE. It spreads by its long roots and when you try to dig up the roots obviously some bits get left behind. These then propogate like root cuttings. As well as this I can't really see a great benefit for wildlife as I'm sure other things like the bluebells which it swamps are more beneficial. What is your story?

Enchanted night shade and arums, bitter cress to name just a few that love to take over the garde when they can.

Ergates

Wild garlic!

Bindweed. If I pull out new shoots every two or three days I can stay on top of it but it goes wild when we go on holiday.

I don't have a particular one, just a variety of nuisances that vary from year to year. This year it looks like it's going to be arum maculatum. Last year it was wild strawberries, before that, geum urbanum

Welsh poppies, because they have a long taproot and I am usually too lazy to remove it fully.
Sheep sorrel because it spreads in a bad way and it's hard to remove completely.

But my number one is red oxalis. A completely lost cause. Being red and low, it isn't too visible, so it often gets ignored or mulched over.

Bittercress. By the time I got around to gardening here last year it had popped its seeds all over the blooming place. 

Herb Robert is also quite prolific here. 

Groundsel too. 

I’m not counting bindweed cos it’s next door…..for now!

In my last garden, it was ground elder...I ended up ripping up entire beds to get it out. My current garden is paved and chipped (I rent) so I leave a lot of the weeds - Welsh poppies, forget me not, bitterness and even some borage sprung up - and I try and leave a corner of willowherb for the elephant hawk-moth caterpillars. I do pull up groundsel especially when it gets a rust fungus because it looks so bad. I'm still working on some tall grass that came from cheap birdseed though, it's the bane of my life (although the same birdseed gave me some lovely flax, so I can't complain).

(Enchanter's nightshade is a good browsing plant for deer...but I don't know how relevant that is in your garden @alexryzawlskiqBU-X4OF!)

Be glad if you don't have creeping cinquefoil in your garden, because if you have it, then there is only one way out: dig up the entire garden and start from scratch.

Bindweed, bindweed and did I mention bindweed!
