I have a garden. It's been dormant for a couple years. When I raked off the dead leaves this spring, I found black soil, with some worms and a snake. A friend told me that was perfect.
I grew a dozen basil plants of a couple different varieties, as well as a rosemary bush (that had lasted a couple years) and some swiss chard, and some cherry and pearl tomatoes, and a few other plants.
Basically, my feelings about a garden are to start with a nutrient-rich soil, keep it wet, and enjoy the fruits of your lack of labor.
The basil, all of it, grew impressively with regular rain or sprinklering, and I ate many meals that had basil as a significant component. The cherries I mostly enjoyed a couple times a week after going out for a harvest.
Terrestrial plants are sooo much easier than aquatic ones.
