To further secure the floating gardens,
mud retaining walls were built up around the raft to hold it in place.
These also acted as walkways that connected the many floating gardens of
the Aztec capital city of Tenochtitlan.
The floating gardens were quite
successful. The Aztecs used the gardens to grow chili peppers, squash,
corn, tomatoes, and beans.
The Aztecs created more land by filling
in marshlands and swamps. They created even more by designing dikes to
hold back the water.
