Plant agaves in sandy, well-drained soils. Water the new planting regularly until established. After the plant is several years old, it will flower. Once it blooms, it will grow pups from the side of the plant that can be harvested to create new plants or can be left in place to create a mass planting.  Pruning and fertilization are not required; however, if you would like to fertilize, you can do so with a well-balanced formula in the spring, summer, and fall.
