Well, I did put like a million holes the the bottoms of my jugs! My husband was like "I don't know much about all this stuff but that seems like over kill"
And then I have them in crates with holes too.
They do seem to drain very well. But I confess when we had three days of super rain early this week I did cover them for part of it.
Next year I will make my own soil mix and I will feel much better about that.
