I can understand how important it is to get rid of these weeds. While you are waiting for your expert answer, I have found a link that will provide some information and instruction. It does contain the procedure in a step by step process. I hope this will help you.
Just to make sure I understand, you bought mulch and it contains thistle seed, and the seeds are now germinating? Or you already had thistle, and thought the mulch would help, but it did not. Please provide more detail, so I can better answer your question.
I was not at my home for 5 months last year and weeds came. I was not there to take care as they appear. So then winter came n then spring with all weeds. I got my bushes trimmed n mulched n thought that weeds will disappear. But after a week the weeds are back n are too many then before.
Weeds are survivors, aren't they! Some thistle species have either long taproots (like a carrot) or an extensive network of underground stems that enables them to spread. Either way, the plants have plenty of stored energy to push through the mulch. ------- One solution would be to spray them with a weed killer, although if the weeds are close to the bushes, you could damage the bushes if the weed killer gets onto them. If you want to try weed killer, you could use Round Up, unless your soil has a lot of gravel. You can keep the spray from getting on the bushes by using a big piece of cardboard to block the stray spray. ------- Another option is to rake back the mulch, cut down the thistles, lay a thick layer of newspaper or a sheet of cardboard on the ground, and then cover it with the mulch. The newspaper or cardboard forms stronger barrier than the mulch; some thistle might break through. ----- Another method is to dig up the thistles, getting as much root as you can. Repeat for any that come back. Eventually you will force them to use up all their stored food, and they will die.
thanks everyone, I am going to try some especially the mowing in the hay field and the paper/cardboard in the garden. I have been spraying. couple years ago even cleaned out the entire garden and sprayed with ground clear and left empty for a year. it helped but they are coming back
They do require diligence. It sounds like you can now get them when they are small and few. The weeds in my lawn and garden are gaining momentum as fall approaches. I spend a little time weeding each evening. I'll need a few good hours to get caught up.
