Creating a Wildflower border to lawn

I have a fairly decent sizes lawn and I would like to make wild flower borders around the edges of the lawn. I'm thinking these borders would be a couple of meters wide.

How do I prep the ground for this? I assume I can't sow the wild flower seed onto the grass? Do I need to rotovate the area? Am I too late into the year to do this?

 

I'm just a novice but IMHO no prep needed..you would just need a reasonably fine tilth to sow wild flowers and the poorer the ground the better...not a good idea to try to sow seed into a lawn as the grass would compete too much.I think you may get away with sowing wild flower seeds now..but hang on whilst someone who really knows what their talking about comes along.

 

Creating what basically constitutes a wild area, really IMO call for much. A simple stroll over common land, a clearing in a wood etc. The wild part really is the natural state. So soil condition and preparation, the least said and done perhaps the better.

I am concerned that you have a lawn, no doubt you cherish it. Now you wish to surround it with basically a wild border. Warning bells are sounding. The majority of wild plants seed profusely, and the seeds are in the main wind distributed. Please stop and think. When mowing, tending to the lawn. Oh no! a buttercup or plantain. My friend, are you with me? You have your lawn and now you want to fence it in with wild plants. I wish all the best.

 

Yes I hear you loud and clear. For now what I've decided to do is just go no-mow in 3 corner areas of the lawn. I'm just going to let it go a bit wild, see what springs up in it. In one of the bigger areas I'm keeping a path through the wild area which is mown.
