Agave americana is called the American century plant because grumbling gardeners once thought it took that long to flower. However, the wait usually isn’t more than 30 years, with some agaves blooming within 10 years. If you were to pass on after flowering, you might put it off, too!

Fortunately, agave plant care is easy, and the plant usually makes pups that carry on after it dies. If provided with its preferred conditions, this type of succulent can take care of itself and is as tough as the “nails” which often tip its leaves. With its bad-boy good looks, who needs an agave plant flower, anyway?

Agave Plant Characteristics

Native to Mexico, the West Indies, and the U.S. Southwest, agaves make rosettes of green, gray, blue, or variegated—often toothed and spiny—succulent leaves, some sword-shaped, some shorter and squatter. At maturity, the different types of agave plants vary in height from 1 foot to 6 feet and their flower spikes from 6 feet to 35 feet.

An agave plant bloom is hard to predict, since most species don’t flower until near the end of their lifespans—a period as short as 5 years or as long as 30 years or more. Each rosette produces only one spike, initially resembling an asparagus spear, which shoots up to look more like a telephone pole. Some species flower on that spike and others make horizontal branches that bear panicles of white, green, or yellow tubular blooms. After they wither, so does the original plant in most—though not all—agave species.

Recommended Agave Varieties

  • Artichoke agave (Agave parryi): One of the toughest species hardy to dry climates in USDA hardiness zone 7, this artichoke-like type has roundish gray leaves and may grow 2½ feet tall, boasting orange buds and yellow blooms when it flowers.
  • Blue agave (Agave tequilana): Agave plant tequila comes from this intoxicating species that grows up to 5 feet tall with narrow blue-green toothed leaves and green flowers in zones 9 and 10.
  • Century plant (Agave americana): This common variety can reach to a height of 6 feet with sword-shaped, toothed gray leaves and yellow blooms in zones 8 through 10.
  • Foxtail agave (Agave attenuata): Also known as the spineless century plant, this species grows 5 feet tall with spineless, broad pale-green leaves. It flowers frequently—without dying—in zones 9 through 11. Its greenish-yellow blooms appear in a spike that arches at the tip to resemble a foxtail.

Planting Agaves

Proper planting sets an agave plant up for success in its long life to come. When choosing an agave, consider the hardiness zone you live in if you plan to grow it outdoors, as well as its size if you’re planting it in a container. (A. bracteosa and A. colorata are a couple of container options.)

If you have children or pets who will be playing in the vicinity of your agave plants, you’ll probably want to choose softer, “friendlier” species such as A. attenuata. It doesn’t have spines, making foxtail agave plant care a bit easier than that of more prickly types.

When is the best time to plant agave?

Agaves should be planted in spring—between March and May, after the last frost passes. If you purchase one from a local nursery, take note of which side faces south so you can position the plant in the same way once you get it home, thus reducing transplant shock.

Where can agave grow?

Choose a site that receives at least 6 hours of sunlight per day and has excellent drainage. Preferably, place the agave at the top of a mound or slope with sandy or gravelly loam that doesn’t contain much humus. If you have clay soil instead, mix in decomposed granite or pumice to make it lighter.

How do you plant agave?

If the plant hasn’t already been growing outdoors, expose it to sunlight gradually over a period of a week or so.

  1. Wear gloves, goggles, and skin-covering clothing when planting large agaves, since their teeth and spines will scratch and sap that drips from a broken leaf can give you a painful rash.
  2. Dig a hole nearly as deep as the plant’s root ball.
  3. Set the root ball in the hole, with the plant facing the same direction it did in the nursery, high enough that its crown remains above the soil surface after you backfill the soil.

Can you grow agave plants in containers?

Agaves grow well in pots and can serve as houseplants in climates where they aren’t hardy. Choose pots that are heavy, shallow, and wide for larger agaves—making sure that the containers have drainage holes—and fill them with a cactus and succulent potting mix. Potted agave plant care has requirements similar to that for plants in the ground: lots of sun and not much water.

Watering Agave Plants

Because agaves store moisture in their leaves, they don’t need large amounts of it to survive and are more likely to die from too much of it rather than too little. In summer, water them no more than once per week, cutting back to no more than once every 2 or 3 weeks in winter. Of course, If Mother Nature provides water through rainfall, you won’t have to. If she provides too much water in your climate, so that the agaves rot, consider placing them in raised beds, on mounds, or in containers for better drainage.

Agaves growing in containers need regular and sufficient watering. However, always check to make sure the container’s mix is at least half-dry before giving it more water.

Fertilizing Agave

Because they originated in “poor” soil, agaves don’t need many nutrients to survive, and some gardeners don’t fertilize them at all. If you prefer to do so, use a type of plant food intended for cacti and succulents such as 1-2-2, in which the first (nitrogen) number of the ratio generally is smaller than the last two. If you prefer to use a balanced all-purpose fertilizer such as 10-10-10, apply only about a fourth of the amount recommended once in early summer.

Fertilizing agave might force it to bloom sooner, so keep that in mind. If you fertilize an agave, only do so during its growing season, not in winter. Container-grown agaves might benefit more from fertilizer.

Propagating Agaves

To propagate these succulents by offsets, simply find one of those agave “pups,” which has its own roots, and cut it free from the mother plant, potting it up separately.

Charles Merbs of the Central Arizona Cactus and Succulent Society recommends sowing agave seeds in a container filled with a mix of one part potting soil and one part sifted crushed granite. Lightly cover the seeds to a depth of only half their diameter with the mix. If the container is kept warm in bright, indirect light, the seeds should sprout in 4 to 8 days or so.

Safety Considerations

Many agaves have both jagged teeth on the edges of their leaves and sharp spines at the tips of those leaves. Some growers prefer to snip the spines off to prevent them jabbing passersby, but you may instead opt to keep the plants in an out-of-the-way spot where they can be admired from a distance.

Agave sap contains calcium oxalate crystals that could painfully irritate and ulcerate the mouth of any person or animal who tries to eat the plant. That sap also can cause a stinging and blistering rash wherever it comes into contact with bare skin.

Potential Pests and Diseases

Agaves commonly suffer from crown rot due to an overabundance of moisture collecting inside their rosettes of leaves. To prevent this, grow them in a very well-draining location and water the plants from the side to avoid pouring water directly into the rosettes.

The plants also attract inch-long black agave weevils, which chew holes in the agaves to lay their eggs there, introducing a bacterial rot exacerbated by larvae digging deeper into the foliage. Dispose of all affected plants. You could also try applying an organic insecticide that kills grubs in the soil.

Overwintering Agave Plants

Gardeners growing agaves in pots likely will want to bring them indoors over winter to protect them either from freezing temperatures or too much precipitation.

When is the best time to bring agave indoors?

In zones where agaves aren’t hardy, bring them indoors before your first fall frost. Although some tolerate mild frosts, freezing temperatures may turn the more tender types—such as the foxtail agave—to mush. Others, such as the artichoke agave, can survive temperatures below zero, but usually only in dry climates.

How do you overwinter agave?

Don’t fertilize your agave during fall or winter. Plants growing outdoors might need a blanket or thermal wrap if temperatures dip below normal lows for the region. For wintering agave indoors:

  1. Place your plant next to a south-facing window where it will receive at least 5 hours of sunlight per day.
  2. If possible, choose a cool site where the temperature remains between 50 and 60 degrees all winter.
  3. Allow the plant’s soil to dry out completely before you water it again.
  4. Rotate the pot a half turn (180 degrees) about once every 2 weeks to keep the plant growing upright rather than leaning toward the light.

FAQ About Agave Plant Care

If you are just learning about how to care for agave plant, consult the questions below for brief answers or the article above for more extensive ones.

Q. How often should agave be watered?

Water your agave about once a week when there isn’t any rainfall, only about once every 2 to 3 weeks during winter, but, again, only if there hasn’t been any precipitation or the container soil feels dry.

Q. Do agave plants need direct sunlight?

Most agave plants should receive at least 6 hours of sunlight per day, but some species such as the foxtail type can thrive in partial or full shade.

Q. How fast does agave grow?

As has been proved by how long they take to flower, agaves mature slowly. As they age, they also can spread as they produce pups.

Q. Is agave the same as aloe vera?

No. Although the century plant (Agave americana) sometimes is called American aloe, it is an entirely different plant than Aloe vera.

Q. Why is my agave plant dying?

Agave plants are most likely to die from overwatering, which rots their crowns or roots. If an agave bloomed recently, that signaled the end of its life and it’s time to transplant a pup or purchase a new plant.
