Veggies wont grow well in pure compost so make it at least half soil, better 70-80% soil. Choose a small-holed cloth.

Slugs should still be a problem. If you could stand using a chem, mix 50-50 sevin and flour [any baking kind], ito a salt sellar type jar with a cover [eg- oderless spice jar]. Place tiny dots of the mix about 4" apart -theyre not smart enuf to go very far!]; repeat when necessary.

My small jar still has most of it left after 4 years. Lable well; store dry.

Here is something that I just recently did in my own garden:

I have accidentally hit on a pest deterrent that can be used and or modified in several other ways as well.
Recently I transplanted my cardinal climber vines directly into my yard along a fence. Knowing how aggressive my husband is at mowing and weed eating I knew I had to devise a method for keeping him and his machines away from my little vines until they were at least more visible. I started looking around the garage and found a roll of plastic mesh gutter guard. Now this seemed promising as I could cut it to the length I needed with just a pair of scissors to go around the area I needed to protect from DH. The next morning I found a couple of slugs caught in the mesh. AHA! I now had a slug deterrent! Then I added some to the bottom part of an 18" tall picket fence that I had just made to go around the perimeter of my butterfly/hummingbird garden to keep the voles out. At last another success as they couldn't go in and munch on my young seedlings. The bottom and top of the gutter guard has a saw-toothed edge so I dig a little trench and push it down into the dirt. It could also be used around new individual transplants pushing it right down into the ground around the plant. Since it is an open mesh the roots can grow right through it. It is very inexpensive and looks neat if it is exposed. You could also use several lengths wired or tied together to get wider widths, attach to a frame and make a trellis screen or use 2 or 3 widths tied together and insert along an area to keep out rabbits etc. by fencing the garden with the mesh attaching it to stakes or posts at the corners of your garden and maybe midway between the corners if you have a larger garden area Just thought I would share my idea with everyone.
