I use a lot of pebbles in my garden, especially around bonsai plants and succulents. I prefer rust colored, white and grey pebbles around plants.
The bigger rocks always adorn the bonsai plants and weeds take refuge under them.
I need to remove these rocks once in a while to clear out the weeds.
Last month I found a couple of small rocks very smooth and nicely shaped in one of my bonsai pots.
I removed them as usual with my bare hands and they were slimy. Then the pebble moved.
I figured that they were slugs not rocks.
I almost threw up. I just can't stand slugs and with the incessant rains they seem to grow in every pot.
I am never seen without gloves in my garden these days.
