Before you plant your Agave americana, first select a location with well-draining soil, full sun exposure, and lots of space to grow. Due to its large size, sharp tips, and hooked teeth, do not plant Agave americana near paths, sidewalks, driveways, utilities, or other locations that may cause harm to passersby.
When planting, make sure to dig a hole twice as wide and deep as the agave's root ball. Fill the hole with some porous soil, like Kellogg Palm & Cactus Mix, and place the agave in the hole, then add the remaining soil, making sure to compact the soil around the plant's base. Thoroughly water to help the soil settle around the roots. Water thereafter when the soil is completely dry. Excessive water will lead to rot.
The Agave americana is a prolific pupper, producing numerous suckers or pups that can be considered weeds. Removal of the offsetting pups is recommended. Use a sharp shovel to divide, dig, and dispose of pups before they take over the landscape. They are easiest to remove when they are young and small. Use caution when working around Agave americana’s sharp tips and teeth.
Agaves are monocarpic plants, which means they only flower once when they reach maturity. The rosette will eventually die when the flower is done blooming. The plant can remain in flower for a long period of time. Agaves may produce offsets or pups before dying, which will continue to grow until they flower. Agave americana typically matures and blooms after several years (generally around 10-35 years) on a 15-25 ft. tall stalk.
