Agaves are known for their ability to thrive in hot, dry conditions, but they can actually tolerate a wide range of light levels. While they will typically grow best in full sun, they can also do well in partial shade. The key is to provide them with enough light to maintain their compact shape and prevent them from getting leggy. If you live in an area with very hot summers, you may want to provide some afternoon shade to prevent your agave from getting sunburned.
