Origanum vulgare 'Aureum' in the lawn.

[Diane]

I have patches of golden marjoram growing in the lawn and can't get rid of it. It started off last year, in small patches, and has spread now over a quarter of the lawn. We mow regularly, but it's still there. We've put weedkiller down too - but it's still there! And the patches are getting bigger.

How can we kill it off - there's too much to dig up.

It's self seeded itself from somewhere?

Can anyone help, please.

A gold lawn that smells nice would be different, and would survive the droughts well, it wouldn't need mowing as often either. My golden oregano is in a tub, memo to self don't let it seed.

Hi NB,
I would say let them seed but not in the lawn and be thankful for any viable seed that come your way.
Diane,
Try putting salt on a small patch and see what happens. Not masses just a light sprinkle. I kill off flat thistles in the lawn with about a quarter of a teaspoonful right in the centre of the plant and they a dead in no time so I am sure that a small experiment will not do that much harm and who knows may work for you.

Was only joking Diane. Lawns have grown slowly in the drought and conditions have favoured the drought tolerant plants. Thinking about your problem, oregano dies off in winter, if the salt idea doesn't work, maybe a lawn feed in spring and let the grass get long hoping it smothers the oregano? It might work if the grass starts growing earlier and you keep the lawn moist so that conditions favour the grass?
Johnboy yes, I am always grateful for any viable seed, nature is very generous. At the moment I have loads of flatleaf parsley seed which I will plant between the asparagus, my best parsley always seems to grow really well with asparagus, they seem to be good companion plants, or maybe like the same conditions. The lovage is seeding like mad too. The local fungi are popping up all over the place, again very early, it's usually nearer to autumn, I spotted brown boletes under some oak trees and some tall whitish ones on the lanes verges edging local woodland. I love to try and identify fungi , though not always easy some are very similar

Thank you for your replies....the salt sounds promising. I'll give it a go.

Much appreciated.

Dear Diane, you could get a price from a lawn-care company, for just a weedkiller treatment, it's often not a lot more than what it would cost us for the spray.
And they should come back free, for a second dose if there are any weeds left.
