Lisa,

I can certainly relate!! :O)
One thing that might help is creating collars out of 2 liter pop bottles or anything similar. Place them around the seedlings to help you know where they are and to stop the mulch from tumbling on them. When they are big enough you can remove the collar. This will also help by preventing the cutworms from destroying your new plants if you bury the collar about an inch in the ground.

Lisa, I was watering the dianthus seedlings yesterday and realized one was missing. Found the remains under a footprint -- I must have stepped on it accidentally. Tried to brush off the dirt, but I think that one's a goner. Clodhopper's a good description for me.

It's so easy to step on the little sprouts! I saved my crushed egg shells all winter and sprinkle some around the seedlings to keep the slugs away. This also helps me to spot them!

I also found I cannot plant them with gloves on. And I use well composted leaf mulch for planting, instead of the larger clods from the hole. It really seems to have helped them get a quicker start.

I have lots of mulch still in the garden. When I plant out I remove the mulch. My only hope is to look for my garden's bald spots and I know that's where my seedlings are. As the number increases I can already tell that I'll be having boo-boos.
