As one of the original critics I guess it is appropriate for me to be one of the first to step up here. First, I've linked to your original thread below, but the "before" photo now links to the "after" photo instead so no one can see what you started with. If I recall it was a circle, either full or three quarters, built of two rows of allen-type block.

Something about this photo shows more of the slope that is there than I originally saw, and I still can't tell how steep it might be. If the mulch loss is really a problem, then I guess you could always consider installing brick all the way around to create a bit of a "raised bed" - level with the edging, but that would put it above ground at the pavement and driveway sides.

But if it is really only a small problem, then I can see three options.

First, a broom. I never knew this was a gardening tool until we recently built some patios. Now I see it is essential, and sweeping has become my last step of the day in gardening.

Second, take the mulch down a little, or let it settle and don't replace it.

Third, a ground cover necklace - but I'm not sure I like this look, and some mulch will still escape and it will be that much harder to sweep it back in.

But it looks great planted up.

Here is a link that might be useful: first thread

Thanks.

As always, it pays to check with you guys. You are correct. I changed the Alien Landing Pad (Circle looking edge) to what I have now and am too embarassed to even leave the picture out there.

Mulch wash is really not a problem. Its a level bed with 4 inchs of soil and 2 inch mulch. I dont mind using the broom or the leaf blower to get this right. I was just wondering how people were handling these kind of raised bed that appear to have the tendency to wash.

Atleast in my case it only happens on the pavement side. My buddy lost all of it after the non stop rain we had in CT over 2 weeks.

I didn't see this in the original thread, but you didn't put down landscape fabric, did you? If you did, how do you feel about shoveling up the mulch and taking it back out?

I've not had any major mulch washout in any beds except where the previous owners used that stupid fabric. If it didn't involve crawling under thorny shrubs I'd rip that crap right out; and eventually I know I'll suck it up and crawl underneath anyway. Until then, I have to get out the broom after every rain.

Here's another idea. Plant an edging plant on the garden side of the bricks. One that comes immediately to mind is liriope/monkey grass.

These are a relatively dense plant that quickly grows to about 1ft tall and is very easy-peasy to maintain...just hit it with a weed whacker once or twice a year. When mature in 1-2 seasons, they will grow together to form a miniature wall around the bed. It also looks great with annuals and small shrubs.

Shredded bark mulch seems to "knit" together and stay in place better than the mulches that are more chunky.

We have very elegant mulch beds around here where I work on level with concrete. The squirrels and chipmunks have fun digging in them. There's always little mulch sprays around. Saypoint has the best suggestion I can think of. But the broom will have to be used too. There is no good solution edging wise. I have the same problem with mulch creep onto my brick patio. The reason I don't like it is I think it encourages weeds to grow between the bricks due to bits of bark accumulating and decaying into soil stuff. At least you don't have that problem with the driveway!

It appears you didn't allow for the mulch when you did the final grade next to the driveway. The mulch, when installed, should be just below the level of the driveway, not higher than it.
Rake the mulch aside and dig a shallow ditch next to the driveway and then fill with mulch. The mulch should be thicker next to the edge. That's where the weeds like to grow.
