You can sow them anytime in a tray with peaty compost put in the garden shady place don't let them dry out keep an eye on them can take a long time to germinate I've got some just germinated after 10 months be patient
some growers say they need a cold spell before germination

when I first moved here 3 years ago the garden was a slug haven even the lawn was crawling on a night time used nematoides twice the first year the following year once this year so far not used it is important to kill the ones underground to decrease there numbers it works , now something I have used this year hostas I sprinkled a circle of remin Rock dust 4 inches away from the plant they are as clean as whistles this rock dust seems expensive but acts as a fertiliser and the size of the bag lasts and lasts maybe I have found a cure from slug damage by chance
Zenjeff, what colour is Remin rock dust?
Rock dust is finely ground volcanic rock from Scotland. It was marketed as Seer or verve , but now seems to be branded Remin. It is all the same. It is used to remineralize poor soils. up to a kilo per square yard can be applied, it works best when worked in by worms in a humus rich soil. The marketing people claim that the plants grow stronger therefore are more resistant to pests and diseases.
You can get it off of Amazon or from b and q
I used a one tonne bagful along with a couple of trailerloads of farmyard manure on my veg patch. I have not noticed any decrease in the slug population in the veg patch. I still drown a lot in slug pubs.
It was pretty poor soil when I took it over. I did get some magnificent onions the first year. The onion patch was a mix of sand and shale, it got six inch of well rotted fym on it plus calcified seaweed (maerl), rock dust and blood fish and bone. It's pretty good soil now.
I think my veg taste better than any you can buy, but I'm probably biased.


If you Google rock dust, start with the seer centre. The only place it doesn't seem to have improved crops, is in the wheat belt of Australia, which is really sandy soil. It needs the humus and fibre and worms for it to work. Mixing it with home made compost is the way to go if you only have a small bag.
The RHs have done trials on rock dust, and suggest that it does not have any beneficial effect,
Regarding Meconopsis seeds; I always sow mine in Autumn, as they seem to need a period of cold to germinate.

rockdust is a dark grey in colour
This is a young Hosta in the ground I planted last summer you will notice the rock dust if you look closely and no slug damage taken just now so it works for me
