I'm new to gardening, and started a container garden in Spring of 2009. Last Spring, 2010, when I went in and prepped the containers for planting again, I noticed that several of them (big, half wine barrels) had small centipede-looking bugs in them, that seemed to be living under the dirt.
Are these harmful bugs? I also found a few spiders (daddy long-leg kind) the first year, but left them in there because I thought they might eat the bad bugs.
Any advice is much appreciated!
