Does anybody have any hands-on experience with DGM?

I read in the AHS info that this midge has only 1 life cycle per year.
Does that mean that if you would prevent all your DL's from blooming (by cutting all scapes for instance) for a whole year the DGM is gone from your garden? Whistling

In theory yes, but although I've suggested it to a few people I don't know anyone who has been willing to sacrifice a year's blooms. There's also the problem of where it came from. If it is infesting a neighbour's garden and came to yours from there then it will eventually come back whatever you do.

I have small garden and not that many DL's yet... Whistling

I'm sure I got this 'present' from a person who's seedlings I bought this year Thumbs down
He lives at the other side of the country and gave me the plants with clump..
I didn't know any better and placed them in my garden without removing and disposing of the soil Sad

Does anyone nearby you grow daylilies? I'm not saying the midges necessarily came from a neighbour but if yours have spread to there then it may not be possible to get rid of them - you'd need to get the neighbour to remove all scapes too.

No, I'm the only one in my block.
Further along the road they have a Stella, but that's about 1 kilometer away, and my garden is at the back of the house and their Stella at the front...

How far can a DL Gall Midge travel on it's own? Confused

Today I checked the H. Fulva one of my neighbours grow. It looks perfect. The other neighbour growing it has it in the back of the garden, so I don't think it can travel here.

We don't know how far it can travel on its own but it is not a strong flier. Presumably the wind could help it though. If it's not in the neighbourhood then your scheme of getting rid of it by sacrificing all scapes may work. But can you also resist buying daylilies with buds or in pots in the future?
