jel,
I recognize the rocks and lovin the idea but Ive gotten so obsessed with slugs and earwigs that all I can see are tons and tons of hiding places for those gawd awful bugs and dinner just handed to them. btw, Im looking for a home for hens and chicks, interested?

Sure, just box 'em up and send them a little further 'upnort'! They'd fit right in with the minis in this bed.

And buy yourself some Sluggo! It's pricy, but worth it's weight in gold!

upnort

Find something else to obsess about, there are no more or less places to hide, slugs will find a place to hide. They have to be killed.

jel48, copper is the product that stops root growth in spin-out, if they are copper bearing let us know if you have a growing problem.

You can make a drain in the ground:
dig a trench
line with landscape cloth, the heavy cloth used in pond construction is best
line with gravel
lay a fabric covered black drainage pipe on the gravel
cover with rock
runoff will drain away

Now you've moved the runoff somewhere else, lots of ways to use this water such as a bog or series of bogs catching the water runoff.

see bog below
