An apothecary is a person -- or an establishment where such a person works -- not a garden. Odd use of the word.

Did it make sense? Were you still able to understand?

It's a bit weird, but makes sense as a rhetorical device. It's sort of like saying "Growing your own vegetable market".

It's not literally true, but it expresses the idea that you are growing a wide variety of things that one would find at a vegatable market.
