Yes, I get that too.

In compost yes me too, even had the odd tiny mushroom

And worst of all, Bermudan buttercup,grrrrrrrrrrrrrrrrrrrrr!

Well it sounds pretty OB?

You shouldn't get weed seeds in potting compost, whether it be multi purpose or John Innes. You will get them, though, in conditioning composts and very often in bought topsoil.

I've never yet bought topsoil or compost that hasn't produced weeds. It seems to be worse now than it ever was.

Rotten compost then, I wouldn't be buying that again - in theory, any potting composts sold on the market should have been sterilised to kill off weed seedlings. Not true of topsoil though.

I have found tons of clover in my compost bought from Homebase which is annoying but no grass. Its a pain when that happens isn't it?

Oxalis cornuta may sound pretty, but it is a thug. This will survive being sterilised by the way, or least ways I have never managed to kill it off, even with Formaldehyde or microwaves.

...teaches me for buying the cheapest compost....

you find a lot of old mushroom soil ends up being sold / given away as topsoil but its realy good as you dont get weeds because the greenhouses are always blanked out .

you cheapskate sid lol .i wouldnt worry weeds get in to soil anywear one way or the other even on top of membrane so its just path of the coarse realy i guess sid.
