Agave karatto (Antigua Agave)

Last updated on August 17th, 2022 at 01:20 pm

Agave karatto (Agave Antigua) is an evergreen plant that can grow between 6 and 12 feet tall. Its trunk can be between 18 and 24 inches in diameter, and its large leaves can grow up to 5 feet long, which makes the agave a striking houseplant or centerpiece in any room.

Agave karatto requires little care from homeowners, as it grows well in dry areas and doesn’t require much water to stay healthy. However, if you want your agave to thrive, there are several steps you should take while caring for your houseplant.

The Agave karatto gets its name from its native habitat on the island of Antigua in the Caribbean Sea. The Agave karatto is also known as Century Plant and Maguey among other names, but today we’ll focus on one thing, how to care for your new plant!

This plant requires little maintenance and can easily be enjoyed in any room of your home. It’s important to remember that you must provide specific care conditions for this plant, if you don’t provide it with the right environment, it will die!

Origin and distribution

Antigua agaves are native to a small area of northern Guatemala and southern Mexico, where they grow in scrubby, rocky, or sandy soil. They’re also cultivated in many parts of North America as well as in Australia and New Zealand.

Many gardeners are growing these tough little plants for their beauty alone, but it’s really hard to resist cutting into one at some point: Their juicy stems make a sweet treat that tastes like a cross between an artichoke heart and a pineapple.

The juice is so delicious that you can drink it straight from the plant, though we recommend mixing it with water first; if you don’t have any on hand, you can substitute agave nectar or honey. The leaves are edible too; just slice them off and sauté them in olive oil until they turn crisp and golden brown.

Agave karatto propagation

There are two methods of propagation; both take a lot of patience.

The first method is division. Division involves digging up a whole rosette, cutting it into pieces, and replanting each piece in its own pot or directly into your garden.

The division process can be extremely slow because it takes five to six years for a plant to fully mature and develops enough rosettes to reproduce on its own. However, division allows you to control exactly what will be planted and where they will grow in your garden.

If you have an older agave that needs dividing, contact your local nursery or arboretum to see if they will divide it for you. They may also sell divisions of their agaves already started.

The second method is cuttings. Cuttings involve taking a cutting from one plant and inserting it into the soil to grow roots. This method can be quicker than division, but you run the risk of spreading the disease if you don’t disinfect your tools after each use.

Once your Agave karatto has grown new rosettes, it’s time to start thinking about reproduction. This step will take some time because you must wait for your agaves to flower before they can reproduce on their own.

Agave karatto care information

Agave Karatto

Agave karatto is a succulent so it needs very little care. Be sure to select a location that has bright, indirect light and does not allow it to be in full sun, as it will burn. A bit of sunlight is ok but if you have a house plant that you like to keep in direct sunlight, move it around occasionally to prevent overheating.

If your house plant sits next to an open window with no shade or curtain then consider getting one.

Light requirement

Agave karatto prefers to live in a place with direct sunlight for most of their day. While they can survive in low light conditions, they won’t thrive without proper light exposure. But be careful to not over-water them as well, if you water them too much, they will rot and kill your plant.

Soil/potting mix

Agave karatto requires well-drained soil to thrive. As with many other succulents, agaves dislike a lot of water so it is best to use a cactus mix for optimal drainage. If you do not have any available, a 50/50 mix of regular potting soil and perlite is recommended.

Most commercially produced soils will do just fine provided they don’t contain too much compost or fertilizer residue as these can cause root rot in sensitive plants such as agaves.


Antigua agaves are fairly drought tolerant, but they do best with consistent water. Water once a week in hot weather and less frequently in cooler conditions. The soil should be kept moist to a depth of several inches.

Never let the soil dry out completely between waterings, which can cause root rot and other problems. Plants will grow better if you keep them well-watered during their first two years. After that, they adapt to local conditions more easily.

A good fertilizer is essential to your agave’s growth. Fertilizers with a high nitrogen-to-potassium ratio are ideal because they encourage leaf and stem growth at the expense of flower and fruit production.

Also, fertilizers that contain phosphorous, calcium, magnesium, and zinc are good choices. Apply these fertilizers every six months. If you use organic material as fertilizer, make sure it contains an adequate amount of nitrogen, phosphorous, and potassium.

The best organic materials for your agave include manure or composted leaves or grass clippings. Avoid using fresh manure; it may burn your plant’s roots if applied too often.


Air temperature should be kept between 65 and 90 degrees F during the daytime. Night temperatures can drop to 55–60 degrees F degrees. In winter, your agave will not have to be watered as much because it is going dormant.

The leaves may fall off, but new ones will come back in the springtime. However, if you are growing your agave indoors then keep in mind that it needs light for at least 10 hours per day and water must be provided frequently to prevent moisture from evaporating from its leaves.


High humidity is essential to Agave karatto plants’ health. A large, decorative plant in its own right, requires a constant supply of moisture. Set your agave near a humidifier or place it on top of pebbles and water.

Another great way to increase moisture around your agave is to place moss at its base; soak moss in water until it reaches an extra damp state and gently arrange it around your agave’s perimeter.

The ideal humidity range is between 40 and 60 percent. If your home’s air is too dry, you can increase moisture with a humidifier or by placing pebbles in a tray of water and setting it on top of your agave.


When pruning your Agave karatto keep in mind it will continue to grow new leaves from its center until it has bloomed or begun forming flower buds. If you want to control its size and shape, start early by cutting off any new growth as soon as it begins to emerge.

This is also a good time of year to remove any old foliage that is damaged or no longer serves a purpose. It’s important to note that if an agave does not flower, it won’t produce seed pods. This can make propagation more difficult because seedlings are typically grafted onto mature plants.

When to repot

Plumages, Molts, and Structure

Agave karatto is a slow-growing plant and it can take years for it to outgrow its pot. It is recommended that you repot an agave once every two to three years, depending on how fast it grows in your area. There are some varieties that can be repotted more often, while others should only be repotted once or twice during their lifetime.

Your plant should have grown several new pups by now which makes it time to transplant them into their own pots. The best time to do so is in spring when they begin active growth. If you wait too long then there will not be enough room left in your original pot for all of them.

When repotting, make sure that each pup has enough space between each other so they do not get root-bound. You may also want to consider dividing up one large agave into multiple smaller ones if it gets too big over time since these plants grow slowly and can live many decades with proper care.

Dormancy/Winter rest

All agaves go into a dormant state at some point and may lose their leaves and seem to die. In reality, they are preparing for a long period of rest, where they can slow down their metabolism and better prepare themselves for growing again.

This dormancy is triggered by cold temperatures or a lack of water. If you live in an area that gets cold winters, your agave will naturally go into dormancy during those months; if you live in an area with mild winters it might be necessary to help your plant through its dormancy.

It’s not uncommon for owners of certain types of agaves to bring them indoors during winter months so that they don’t have to deal with watering plants when it’s freezing outside.

Agave karatto flower & fragrance

In addition to being a popular landscape plant, Antigua agaves are cultivated for their large and showy flower stalks, which typically bloom once per year. In late spring or early summer, depending on when they were planted, agaves send up a tall stalk with showy flowers of yellow and orange that reach over six feet in height.

Growth rate

When newly planted, Agave karatto will grow rapidly and may double in size in a year. After they have flowered, the growth rate decreases to an average of 10–30 cm per year until maturity is reached. Growth rates are faster in more northern latitudes and when plants receive sufficient water and fertilizer.

If a mature specimen is to be relocated, the soil should be dug out around its perimeter so that it can be lifted without injuring or killing off surrounding plants by accidentally pulling them from their roots.


The plants are toxic to humans, dogs, horses, and cats. If you’re using it as an ornamental plant or have children or pets, beware!

USDA hardiness zones

Agave karatto thrives best in USDA hardiness zones 9 through 11. They can also be cultivated as houseplants in colder climates, although they will not flower indoors. In fact, some agaves are so cold-hardy that they can even be grown outdoors year-round in U.S. Department of Agriculture plant hardiness zones 9 and 10.

Pests and diseases

Agave Karatto is susceptible to mealybugs, spider mites, aphids, and scales. Other than that it seems to be a fairly hardy plant. If you notice any of these pests on your plant use a natural pesticide like neem oil or soap spray. If you have a problem with scale insects try horticultural oil.

It’s important to not use chemical pesticides because they can damage your plants’ ability to take up water from their roots and can also cause other issues like stunted growth or even death of your agave karatto. If you’re looking for an organic way to control pests then try using ladybugs or praying mantises.


The agave karatto is a very low-maintenance plant and perfect for any garden, patio, or balcony. It takes only minimal care to grow and will thrive with little attention from its owner.

This beautiful plant can enhance any outdoor area and provide an excellent source of color. If you’re looking for an easy-to-care-for plant that will grow in even harsh climates, then add an agave karatto to your collection today!
