I have to admit, I rarely harden my seedlings off. I'm afraid if I put out trays of seedlings my resident chipmunks will think it's a buffet for them. I here you @Sueby. The absolutely best place of a huge garden on my property is the leach field. I was so disappointed when I found out that's what was under ground. I had to get out the schematics of the septic system to determine if it was safe to plant one of my apple trees at the bottom of that slope. The new garden bed I added this year should work well for those plants that need a little shade during the day. We'll see.
