Agave montana, also known as mountain agave plant, is an evergreen succulent plant native to the Americas. While it’s not indigenous to North America, its natural range extends from Arizona in the United States all the way down to Peru and Chile in South America.

Agave montana typically grows at heights between 200 and 8,000 feet (61–2,438 meters), with an average height of 3,000 feet (914 meters). The high elevations at which it naturally grows make it particularly suited to areas with low oxygen levels.

It is also one of the most common agave species found in the mountainous areas of Southern California, Mexico, and Guatemala. Its hardy nature makes it great for indoors and out, making it ideal for landscaping as well as cooking and eating.

Origin and distribution

Mountain agave plants are native to Mexico and grow wild in the states of Oaxaca, Puebla, Guerrero, Hidalgo, Michoacán, San Luis Potosí, Guanajuato and Querétaro in Mexico. Agave montana grows to as much as 16 feet tall and lives to as old as 75 years. The mountain agave plant produces large rosettes of blue-green leaves from stalks up to 10 feet tall.

Agave montana is native to Mexico and Guatemala. Although it can grow in all types of soil, mountain agave prefers rocky, calcareous soils. Its long taproot allows it to absorb nutrients from these rocky areas. The natural elevation range for mountain agave is approximately 1,500 to 5,000 feet above sea level; however, seeds have been successfully grown at sea level with proper training and conditioning.

This plant grows best when temperatures are between 70 and 85 degrees Fahrenheit during daytime hours and 60 to 65 degrees Fahrenheit during nighttime hours. It will tolerate temperatures as low as 25 degrees Fahrenheit but will not flower or produce viable seeds if subjected to freezing temperatures.

Flowering occurs when temperatures are between 65 and 75 degrees Fahrenheit with a photoperiod of 12 hours light/12 hours dark. Flowering normally begins after one year from seed germination.

Agave montana propagation

It may take longer if you are growing them indoors during the winter months or if there has been less light and warmth than usual for that particular month.

You must keep your agave’s soil moist at all times so that they don’t dry out while they are germinating. After they have sprouted, be sure to give them plenty of sunlight and water regularly until they become established. After that, they should only need watering once every few weeks.

Be careful not to overwater because doing so could cause root rot. Also, be careful not to overwater because doing so could cause root rot.

Agave montana care information

Caring for agave montana is fairly simple. It does best in full sun and well-drained soil, but it can also tolerate partial shade. It grows best in temperatures between 60 and 80 degrees Fahrenheit, so it’s ideal to grow in a greenhouse or outdoors during the summer months.

If you live in an area with cold winters, you can keep your plant indoors year-round as long as you give it plenty of light. Otherwise, you should store your plant indoors during the winter months to protect it from frost damage.

Light requirement

For optimal growth, keep Agave montana plants in a bright area with direct sunlight. The plants need full sun for at least three to four hours a day. Provide indirect light for part of each day. Use natural light if possible, instead of artificial light sources. Take care not to expose agave plants to extended periods of sunlight or heat that could damage their leaves.

Soil/potting mix

The plant will require a potting mix or soil containing 2 parts clay, 2 parts peat moss, and 1 part sand. It requires well-drained soil.

The addition of charcoal may also be beneficial to aid in drainage. In addition, it is recommended that you provide a layer of gravel on top of your soil for increased aeration. This is especially important if you are using plastic pots instead of ceramic pots.

Plastic pots retain more moisture than ceramic ones do, so they need more airflow through them. However, with either type of pot, it is still important to make sure that there are drainage holes in them so that excess water can drain out as needed.

When watering, allow some of their soil to dry out before you water again. If it is especially warm, you might even need to water once a week or more. You should be careful if you are giving them too much water, though; Mountain Agaves can rot if kept in standing water for too long.

To avoid drowning your plant, pay attention to its color and adjust accordingly. Also, make sure that it has good drainage and doesn’t sit in any puddles of water for too long.


Agave montana should not be fertilized, as they prefer a natural growing environment that remains somewhat dry. Fertilizing can cause your plant to grow too quickly and harm its root system. The plant’s roots do well when planted in sandy soil, so you don’t need to water them heavily or fertilize them if you have a proper planting site.

However, it is possible to use slow-release fertilizer pellets around each plant. If you decide to use fertilizer, make sure you only add one pellet per foot of space between plants and water with one gallon of water for every 100 square feet of garden area once every two weeks during the spring and summer months.


The ideal temperature for agave montana growth is around 65°F, with a range of 55° to 75°F. The plant can survive below zero, but it will not bloom unless temperatures are above 50°F.

During the winter months when the temperature drops below freezing, move your agave montana to a protected area and bring it back outside in early spring once the danger of frost has passed.


Mountain agaves are extremely frost-tender. As with many tropical and sub-tropical plants, severe frosts can kill them. It is essential that mountain agaves are kept out of temperatures below 5°C. If a freeze is a forecast, bring plants indoors or cover them with frost cloths and insulate containers if possible.

The ideal humidity range is between 50% and 70%. This can be achieved by using a humidifier or placing plants on trays of wet pebbles. If you are unable to achieve these levels, it may be necessary to mist plants daily.


To properly care for your Agave montana, keep in mind that it’s succulent, so it won’t require much pruning. In fact, you should avoid cutting back on too many leaves if you want to achieve maximum plant growth; pruning more than half of your leaves will inhibit growth.

Instead, just focus on removing dead or decaying branches and ensure that each leaf gets an adequate amount of sunlight exposure to prevent browning.

When to repot

Repot your agave montana every two to three years in spring, once it has flowered. The plant will become top-heavy and fall over unless you repot it; when that happens, it will lose its leaves. To repot your agave, simply dig up as much of the roots as possible and replant them in fresh soil.

Make sure you remove all of its old soil and pot with a succulent mix of half sand and half loam. Water well and place in full sun for at least six hours per day. Don’t fertilize for at least one year after repotting.


During dormancy, Agave montana don’t do much, which is why some gardeners forget they have them. This lethargy lasts from autumn to spring. If you want to bring yours out of its dormant state, a little extra heat can often help.

To do so, move your agave away from cooler corners and into an area with more natural light and slightly warmer temperatures for about six weeks during the winter months. Afterward, place it back in its original spot and let nature take over.

If you notice leaves starting to fall off after moving your plant, don’t worry; that means it’s just shedding older foliage and readying itself for new growth.

Agave montana flower & fragrance

The bright yellow flowers of Agave montana can grow as tall as 5 feet and smell like lilies or honey. In some parts of Mexico, they are used in religious ceremonies to mark gravesites, since they will flower even after death.

In many places, they are considered pests because they take over hillsides that other crops could be planted on. However, there is a thriving market for them as live plants, especially among collectors of exotic plants.

Growth rate

The Mountain Agave plant’s growth rate is slow. It takes five to six years for it to grow from a seedling to a fully mature plant that can start producing flowers and seeds. In ideal growing conditions, it takes another five years before it will be ready for harvesting and replanting. The lifespan of agave can reach more than 20 years.

Agave montana plant contains saponins, furanocoumarins, and other chemicals that are known to cause skin irritation. As with all plants, avoid consuming any part of it if you have an allergy to it or have sensitive skin. If consumed in large quantities, agave montana can be toxic for humans and other animals.

USDA hardiness zones

Agave montana thrives best in USDA hardiness zones 9 and 10. In colder climates, it will still grow but may be more susceptible to frost damage. It also requires a lot of water, so if you live in an arid climate, you’ll need to make sure that your plant is getting enough water.

If you live in a cold climate and are worried about your agave montana being susceptible to frost damage, try planting it near a south-facing wall or fence that blocks some of the wind from reaching it.

Pests and diseases

Although usually not fatal, Mountain Agave plants are subject to some fairly aggressive pests and diseases. Leaf-curl disease, for example, is caused by a fungus that causes leaves to dry up, curl and eventually die. Spider mites can also be a problem in areas where temperatures get particularly hot.

These bugs suck sap from plant leaves and webs which can lead to mildew as well as other problems such as yellowing of older leaves and eventual death of younger ones. If you see any signs of these or other pests on your agave plant, it’s important to take action quickly; spraying with an insecticide will help keep things under control.
