Find a well-drained location that receives at least six hours of direct sunlight each day to plant an Agave americana plant. The location should be at least 6 feet from pedestrian traffic.
Space multiple plants 6 feet apart. This allows room for suckers to naturally grow from the base of the plant and fill in the space between the plants. If planting an Agave americana plant in the northern part of the hardiness zone, or U.S. Department of Agriculture hardiness zone 8, which is recommended in some publications, plant it where it is protected from north winds.
Plant the Americana agave at the same level it is planted in the container. Water the soil around the plant thoroughly after planting to ensure good soil-to-root contact.
Spread a 2-inch layer of bark or gravel mulch around the base of the Agave americana plant to conserve moisture and prevent weeds.
Irrigate the plant by overhead watering. The leaves are naturally shaped to funnel water into the base of the plant. The leaves will begin to sprawl outward when the plant is heat stressed. Watering the plant during the summer after three to four weeks of no rain will keep the leaves upright, green and attractive. Do not allow the soil around the plant to remain waterlogged.
