My carrots have been a total success this year, I grew the baby variety, and I have tons waiting still in the garden. The kids were so excited to pick these, I haven't ever attempted root vegetables before. My worry with them has always been soil quality, since they are roots they absorb anything good, but on the flipside, they also will absorb anything bad in your soil. So until this year, when I started using the raised beds instead of tilling into the ground, I have never felt comfortable enough to try.
But now, thanks to my lovely raised beds with organic material that I chose, and I know where it came from, I felt safe enough to try.
