What is this weed?

[Polkadotties]

Over the past few days this has sprung up in my borders and is spreading quite rapidly. I’m not really sure what it is or how to deal with it. It’s too small and there’s too much to pull up by hand. Could use a weed killer but don’t want to harm my plants. Any ideas?

Hoe them and leave them to dry out in the sun.

The weedlings are far too small to identify, but my guess is either dandelions or chickweed.

Haha! I looked at the picture and thought that's a hydrangea not a weed. Sorry Monday morning and all that. I agree with the hoeing.

Haha yes, not my hydrangea.
The border was horrifically overgrown and basically a bed of weeds. I turned all the soil over when I planted my new plants a few weeks ago so I must have disturbed something

It does look like a dandelion at the bottom right hand corner, but the others are too tiny to identify. It'll be very easy at the moment to get rid of them by hoeing.

Teeny weeny weeds, if you hoe or otherwise stir them up they won't stand a chance. This is the best way to keep on top of all weeding - get 'em while they're tiny. And mulch after, that helps to keep them down.

Your hydrangea is lovely.

All of them are still at the cotyledon (seed leaf) stage. The cotyledons are partially developed in the seed, to give the plant a bit of a start while it's still developing a functional root system. They are all simple in shape, so a lot of plants have apparently identical cotyledon. The plant is vulnerable at this stage, so hoeing, especially at the start of a hot sunny day, will get rid of them.

Or you could leave them till they're large enough to pull out, by which time overcrowding will have done its job and there won't be so many.

Pull up after there's been a good amount of rain, it's much easier. If you dig over a bed you're just exposing the the 'weeds' that have been there, underground, all the time. I just mulch between the plants , I never dig apart from holes for new plants! I do get weeds from my compost\mulch because i'm lazy just not so many.

Yes, "no dig" gardening is a life changer!

FromIb I love it !

I genuinely don't know why, but those weeds are making me shudder I've identified a new phobia! When I find out what they're called, I will contact the diagnostic statistical manual people. (Psychologists? Is that what they're called?)
