There's also the Anti-Garden Song, to the tune of Dave Mallet's Garden Song, which gives the dark side of gardening. Both are in Rise Up Singing. I can't remember all the words to the Anti-GS, but here is the chorus:
Slug by slug, weed by weed;
My garden's got me really teed.
All the insects love to feed
Upon my tomato plants.
Sunburned face, scratched-up knees;
My kitchen's choked with zucchinis.
I'm shopping at the A&P
Next time I get a chance
Lots of fun.
