Agave Plant Care Requirements
All succulents, including agave, require direct sunlight, so it is best to place the plant in the south or southeast window. In summer you can move it to the open balcony or loggia for sunbathing. If the windows of your apartment are facing north or northwest and west, the plant needs special lighting with a grow light.
Agave can withstand even the most scorching sunlight, does not burn, and does not require shade like some other succulents. But if the agave was in a low-light place for a long time, then you should not immediately place it in direct sunlight. You have to get it used to the sunlight gradually.
All desert plants do not like excessive moisture. During the period of active growth, the plant requires moderate watering, that is, no more than 2 times in 7 days, so that the soil dries out between irrigations. Water 1-2 times a month in cold weather. It needs good drainage so that moisture does not stagnate. It is important that there is no water in the center of the rosette!
The simplicity of watering is attractive for office space and even industrial areas. If the agave grows in a room with a lot of dust, you should wipe the leaves with it. This is quite problematic, as all agave varieties have thorns and spines. To avoid injury to your hands, wipe the leaves with a damp sponge on a long handle.
The humidity of the air in the room where the agave is located must be sufficiently dry. For the summer period, take the spiky beauty to the fresh air. Make sure the substrate dries completely before the next watering. There must be good drainage, the excess water that has accumulated in the pan must be drained.
You don’t have to place water tanks next to the plant like some plant growers do. Such a measure is necessary for other plant species, which require high humidity.
Due to its origin, agave likes warm, dry air, so the climate of our city apartments is perfect for her. The optimum temperature is 20 – 28°C. At a temperature of 18 – 20°C the plant slows down growth and looks depressed. Spending some time at a temperature of 10°C and below can completely destroy the plant.
Agave soil is undemanding, and in the wild it grows on rocky and sandy soils. It is only important that the soil is not too dense. Good drainage and adding sand to the universal soil mix solves all problems.
The best conditions for agave are well-drained dry and sandy soils.
During the period of active growth, plant nutrition is necessary – in late spring and summer. Yes, fertilize the agave plant, combined with watering, once a month. In winter, nourishing agave is not necessary. This plant is better for undernourishing than for overfeeding. Use fertilizer that is specially made for succulents, as it has everything you need for the plant.
Agave plant grows slowly, and rarely needs repotting. If necessary, transplant young growing plants as soon as they have outgrown the container during spring. A new pot should be 2-3 cm larger in diameter. Take special care not to bury the rosette of the plant when repotting.
Also avoid covering the stem with substrate. Instead, cover it with pebbles for quick drying at the roots of the stem. This is done so as not to limit the supply of oxygen.
It is very important when planting not to bury the neck of the plant, it should be slightly above the ground. Deep planting will cause the plant to rot.
Agave propagates by offsets, which are formed at the base of the stem. Carefully separate them, dry a little to prevent rotting and plant in a loose soil mixture. It is helpful to powder the cuts with cinnamon powder to promote healing. The first watering should take place three days after the appearance of the roots.
It is possible to propagate agave seeds, but it is a very long and labor intensive process. Sow the seeds shallowly in the ground in early March. Water the soil with the sprinkler and covered with clear glass or plastic wrap. Shoots appear in about 7-8 days. The best temperature for seed germination is around 24°C.
After the appearance of shoots, remove the film or glass and after some time transplant into pots with a diameter of 6 cm. After a year, transplant into larger diameter containers. Soil and drainage are the same as for adult plants. Agave seeds of various types are sold in nurseries and online.
Under natural conditions, agave blooms over a period of 10 to 20 years. This is very special. In large species, a ten-meter stem grows within a month, in smaller species it reaches 3 meters. Then gradually thousands of small flowers appear on the stem. The plant dies after flowering, because it gives all its energy to flowering and ripening seeds.
Pests and Diseases
The main plant pests are mealybugs and scale insects. After purchasing an agave from a store, check for pests. At the initial stage of infection, it is enough to wipe the leaves well, especially at the back with a solution of alcohol. The procedure is repeated twice within 4-5 days. If you see that there are a lot of pests, then such insect colonies should be removed with the help of insecticides. Buy them from a specialty store and follow the instructions strictly.
If black-brown spots appear on the leaves of your agave, this indicates a fungal infection. The basic principle of the fight against the disease – special antifungal preparations containing copper.
Medicinal Properties of Agave Plants
Many varieties of agave have healing properties, but the most commonly used variety is American agave. The juice is extracted from the leaves – the main raw material for many traditional medicines. When used externally, it aids in treating minor cuts, bruises, burns, injuries, and skin irritation from insect bites.
Traditionally, it was used internally to normalize metabolism and improve the work of the entire digestive tract. It has a mild diuretic and laxative effect.
Types of Agave Plants
12 Types of Succulents for Outdoors
American agave (Agave americana)
This type contains many vitamins and minerals. It is also considered one of the most effective aids in traditional medicine. The homeland of this species is Central America, but it also got used to life in Russia, in places such as the Black Sea coast in the Caucasus and on the southern coast of the Crimea.
American agave is a plant with a thick short stem and a rosette of fleshy bluish-green leaves, the length of which reaches 2 m. The leaves have an elongated shape, the top of which is twisted into a pointed tube.
An adult shrub of this species in width can reach a size of 3 to 4 m. Flowering occurs at about 6 to 15 years old.
This species has several subspecies that differ in leaf color:

It begins to flower in age from 20 to 40 years, after which the plant dies.
There are two subspecies:
- Agave deserti var. deserti – it is distinguished by numerous rosettes and a perimeter tube of 3-5 mm. Germinates exclusively in the expanses of Southern California.
- Agave deserti var. simplex – this subspecies has one or more outlets and a color tube 5 to 10 mm long. Cultivated in Arizona and Southern California.
Parry’s Agave (Agave parryi)
It has a unique decorative look very similar to the agave parrasana. It is grown in the mountainous sandy terrain of the south of the US and in Mexico. It has a rather loose rosette, with elongated egg-shaped leaves. The tip of the leaves is pointed with a small dark thorn.
The color range varies from light green to gray green. Inflorescences grow to the height of 20 cm and form about 30 brushes, with a set of light flowers.
Foxtail Agave (Agave attenuata)
An interesting representative of the Agave family, which can grow even inside a small pot. The homeland of this species is the city of Jalisco, located in the Mexican state of Guadalajara.
This species has a characteristic, curved stem shape that resembles a gooseneck, which grows to about 1 m in height and has juicy, soft leaves no longer than 60 cm. It has a semi-transparent color from gray to greenish-yellow tones. Before flowering, the stem becomes bare and sheds the upper bushy part. The inflorescence is quite high and can grow up to 3 m.
Yucca vs Agave
The yucca actually belong to the agave family. Many different plants belong to this subfamily, which are usually persistent or perennial and usually cannot tolerate frost. They are native to many parts of the world.
Like all agave plants, the yucca belongs to the asparagus family. The famous vegetable asparagus or agave, whose juice can be used to make tequila, also belongs to this family. The fibers of some types of yucca and agave are processed. Other species serve as ornamental plants in gardens or parks and also as house plants.
Most species of the yucca come from Central America, preferably from Mexico and the border area of the USA. Many species grow in dry areas, but some also in mountainous areas. As a result, they have different conditions for their care. What all species have in common is that they prefer it dry and do not tolerate much rain or waterlogging.
Sometimes the specimens of the species Yucca gloriosa, known as the Spanish dagger, are confused with the agaves. However, their leaves, which are also arranged in the form of a rosette, are significantly thinner and contain less water. This may also be the main reason why these plants are very hardy when compared to many agave species . The Spanish dagger flowers in a suitable location every year and tends to develop a woody trunk base than agaves. This plant can be an exotic-looking alternative if the similar-looking agaves cannot be overwintered outdoors due to the local temperatures.
