Haha thanks. The ragwort is getting pulled this evening :)

Look carefully there is another much smaller one in the picture, middle bottom.

looksee · 21-07-2022 04:01PM

Yes it looks like Scarlet Pimpernel. I tend to let it be unless its in a flower bed. It can be a bit rampant but if its just in an area where you don't mind what grows then leave it be.

Yes, Scarlet Pimpernel, aka Poor Man's Weather Glass, opens more fully the sunnier it is. There is a rare variant which is blue; same species, just a genetic quirk.

A great idea to leave it alone, it will not do any harm, tends not to make it into lawns, rather, more disturbed, bareish areas.

what's this growing amongst my lawn in patches...never seen it before why now?

looksee · 28-07-2022 09:20AM

Self-heal, (Prunella vulgaris) pretty little plant which insects love. Definitely a nuisance weed if you want an immaculate lawn, but if you are happy with the clover/buttercup/daisy/selfheal etc mix, which makes a lovely 'lawn' in my opinion, then leave it be.

Not sure 'why now?' - this seems to have been a good year for it, I have more than in previous years. It prefers moist soil so maybe the spring suited it.

fryup · 28-07-2022 09:41AM

i put plenty of lawnfeed (mobacter) on at the beginning of the season - would that have been a contributing factor?

The Continental Op · 28-07-2022 09:52AM

I'd always put a lot of self-heal down to poor growing conditions. I have really rubbish areas of the garden where the lawn only has a few inches of topsoil and they are full of self-heal. Self-heal seems to do better than the grass when their is competition for water. Its easy to kill it with lawn weed killer but not so easy to sort out the reasons for its prevalence.

Not at all. Mobactor does nothing either way for weeds. There's plenty of clover there too. It's difficult to get rid of if it takes a hold. While it tolerates dry spells it's prefers damp ground. It just got going with the damp spring and early summer on soil with no chemical treatment. Personally I'd get rid of it as it can take over very easily if the conditions suit it.

fryup · 28-07-2022 09:55AM

right so, what's the best way to get rid?

Tony H · 28-07-2022 10:05AM

Wife thinks it’s a flower , I think it horseweed , any ideas

The Continental Op · 28-07-2022 11:36AM

Can't say I recognise it but Horseweed is as good as any from your picture. I did check if it grows here and it does, https://plantatlas.brc.ac.uk/plant/conyza-canadensis & https://maps.biodiversityireland.ie/Species/40744

This has some good info https://www.ediblewildfood.com/horseweed.aspx and pictures.

Horseweed would be Conyza canadensis but there is also another one Conyza sumatrensis which is very very similar

Its one I'd try and get rid of as it is reported to be what they call allelopathic - where it grows little else grows.

It depends on how much there is and how much effort you're willing to put in. Personally I have time to weed it by hand, but you must get all the root out. You can use a lawn weed killer if you wish, but it will take clover etc as well.

Certainly is a flower, Conyza, either floribunda or canadensis, both relatively recent additions to the Irish flora. Probably the most common herbaceous plants on derelict/building sites around Dublin, getting that way elsewhere too. You can try to get rid, but it seeds prolifically, even lifting it out will dislodge and spread seed. Needs little but bare rock to grow on.

Tony H · 28-07-2022 03:25PM

Thanks Blaris really appreciate that ,wife is cleaning up a bit of rough ground near the house , has a few rowan trees , some bird cherry trees and lots of bee, butterfly, bird friendly plants there ,if it flowers and helps the above .

would Resolva do the trick?

Once it's a Lawn Weed Killer.

Should, the other is burn down weedkillers. Horticultural vinegar is one but I would not know where to get it.

The Continental Op · 28-07-2022 09:38PM

Ideal for effective control of broad leaved weeds including dandelions, daisies, white clover, yarrow, buttercups, self heal, deadnettle, speedwell and broad-leaved docks in lawns

and after i spray how long should i wait before i mow the lawn?😶

The Continental Op · 29-07-2022 10:33AM

https://www.boards.ie/discussion/comment/119402839#Comment_119402839

Ideally let the grass grow a bit before you spray and then leave it 4 days before you cut again. So say cut 4 days growth spray wait 4 days before cutting again. However if when you cut you are hardly cutting the self heal then miss out the first bit.

Mac-Chops · 12-08-2022 02:24PM

Am I right in saying this is either couch grass or rye-grass?

It's well scattered around the grass patch and I wouldn't mind leaving it be only it seems to be limiting the growth around where it's growing.

Have started pinching out as much as possible as in the photo and seems to be helping but open to any other suggestions.

A long white sideways growing underground stem would be characteristic of couch grass which I think can be a good candidate for ripping out regularly as when it gets established it can be very difficult to deal with as it can regrow from each bit of that underground stem system that allows it spread so well.

Happy gardening!

Yeah, the image doesn't look like couch grass to me, and I spend my days yanking that stuff in vegetable beds. I think it's just ryegrass. Couch grass leaves are usually broad-ish on the grass scale, not as fine as the stuff one wants to grow.

blackbox · 14-08-2022 06:34PM

Looks like couch (scutch) grass to me.

10-10-20 · 23-08-2022 01:36PM

Can anyone tell me what this is? I planted it's parent in a window-box from a garden center selection-tray and it grew very well as a small, dense shrub (25cm high) for about three years before dying off after seeding. This year I have smaller versions of the plant coming up between my flag-stones, such as the one in the photo, but I'm keen to regrow it.

New Home · 23-08-2022 02:18PM

It looks like a jasmin. Is it scented?

https://www.boards.ie/discussion/comment/119511028#Comment_119511028

I see where you're going with that given the flower, but it's not Jasmine - I have that elsewhere as a climber. This is a small shrub no more than ~25cm when in a window box. I don't recall a scent off it, but I can't tell now as it's has since lost it's (two) flowers.
