Introduction

Agave, the native species of Mexico and the arid and semiarid region of Carribean, belongs to the family Asparagaceae / Agavaceae.  These are succulents with a rosette growth habit that will left you astonishing. They grows well in Mediterranean region but also do well in the tropical and subtropical region.

It has become more popular among gardeners in the water-guzzling landscapes as they enhances the aesthetic value by its dramatic foliage and subtle color. These perennial drought-tolerant species have large leaves with tapering spiny tips.

 

Preferred Zone: It thrives best in the USDA 8-10 growing zones where a seasonal dry period occurs.

 

Why grow the Agave plant?

– Attractive leaf symmetry;

– Drought tolerant and can grow for months without water;

– Easy care and management;

– One of the best option among perennial patio plant

– Also considered fire retardants.

 

Some uses and facts about the Agave plant

1. It is used in making liquor-Tequilla and pulpue (bee-like drink).

2. It can be used for making ropes.

3. Biofuel.

4. It can be used as sweet alternatives as it is 1.5 times sweeter than sugar.

5. Agave plants are grown in the garden for their beautiful foliage.

6. It belongs to the family Lilly despite resembling its morphology with cactus.

7. As many species have spiny leaves, make sure to leave some walking space around them.

8. For growing in a container or as indoor or in a garden small agave species are better suited.

9. Planting with ornamental grasses soften the rough edges and further enhances aesthetical beauty of the landscapes.

 

Planting technique

Agave can be grown by using various methods. Some of the common methods are:

 

a) By seed

Most of the agave species flower between 3 – 50 years of age. Therefore, the fruit develops from the pollinated flower. No special seed treatment is required. But, germination requires warmer temperature so summer planting gives the best result. Selection of seed species depend upon where (indoor or outdoor) you intend to plant.

The seed will start germinating after 1-2 weeks of sowing. Once the plant establish themselves, you can transplant it onto another suitable area. Transplanting time might differs from species to species. For example:

a) A. attenuata– 4 months

b) A. victoriae-reginae– 18 months

Transplant the seedlings in the pots and leave them for about 4-8 month in the greenhouse. After that hardening, off in shade should be done for 1 month before planting outdoor. It will give the best result.

 

b) By Pups or sucker

It is a widely used method in naturally clustering species of Agave such as in arborescent agaves such as A. attenuata. The suckering of young plants i.e.  aroused from the mother plant are called pups which is used particularly in this sort of propagation. 

In this technique, first, separate the pups from the mother plant by cutting with a sharp knife. But be careful not to do the harm to the mother plant while extracting pups. After then, check the presence of roots on each pups as only rooted pups are likely to grow, survive and do good. Immediately after cutting the pups, plant it in well-drained soil. 

 

c) By Rhizome cutting

It can also be done in some clustering type of agave. Cutted- rhizome with at-least one dormant bud are preferred as it provides best result.  But be careful to plant these rhizomes in well-drained soil and cover it with perlite. In 4-6 months the plants from the rhizome will be ready to transplant to another suitable media indoor as well as outdoor.

 

d) By  Bulbils

Small plantlets produced from the axils of exhausted flowers are called bulbils. This method have been found to do best in A. vilmoriniana, A. desmetiana A. atrovirens etc.

 

e) By Coring

It is also a commonly used method of propagation.

Steps:

– First, make a wound by cutting the central growing portion of the plant to prevent further growth and promote the development of new shoots.

– Spring season preferable.

– After 5-6 month, a new plant will arise from the damaged portion which develop roots in about a year.

 

f) By Micropropagation or tissue culture

It is becoming a popular technique of agave propagation due to ease and healthy planting production. Tissue culture in laboratory is more quick with better production and now has been commercialized in a large scale around the globe.

 

Planting care and climatic requirements

a) Soil Preparation

Prepare the soil by mixing sand or perlite (3 sand: 1.5 Perlite). For improving well-drained condition you can use peat moss or cocopeat too. Well-drained sandy soil is the ideal condition for agave but could grow also on soil ranging from rocky to loamy type with good drainage.

 

b) Planting time

Transplant them in the spring or before the rainy season. This will give your plant plenty of time to gain the maximum size. But be aware that while planting, rosette should not be covered otherwise plant will rot.

 

c) Sun exposure

They are sun-loving plant. So, make sure to plant in the area where bright sunlight comes. They even can tolerate scorching sunlight without showing any burning effect. 

 

d) Temperature

They could survive in cold temperature after establishing as well as hot one but grows best in warmer and low humid condition. The optimum temperature for its proper growth is 20-28 °C. Below 20°C plant growth retards while below 10°C plants could not survive.

 

e) Water

Proper irrigation should be done in the seedling stage. But once plants establish themselves, you should cut the water supply. As they are desert plants could grow well in dry soil too. However, proper moisture should be maintained during active growth period. The amount of water also depends on soil moisture content, soil type, weather condition and growth stage of plants. Generally watering twice a week is enough in the early growing phase. While in cold weather, 1-2 times in 2 weeks is more than enough.  They cannot tolerate waterlogging conditions. They show yellowing symptoms if over-watered leading to crown rot. So, proper drainage should be maintained.

 

f) Fertilizer

Although they grow well in undernourished condition than over-fertilizing, additional additional application of fertilizer might be beneficial during summer and late spring. But be aware of over-fertilizing as it leads to flowering and plant die after that. Fertigation (irrigation + water) in a monthly interval gives the best result. In winter, avoid fertilizing.

 

g) Repotting

Agave rarely needs repotting due to its slow-growing nature. Repotting has to be done in case the plant outgrow the container or pot. In such a scenario, transplant the young plants in a container having 2-3 cm larger diameter during spring with special care. Cover the stem with pebbles rather than covering it with soil or substrate because it will enhance drying and facilitate proper oxygen in the root zone. Also, transplant the plant in shallow depth without burying the neck and rosette of the plant to prevent the plant from rotting.

 

Thinking of bringing agave plant indoors?

If you do not have gardens for outdoor planting or if you are living in excessive cold areas then you can grow Agave plants indoors too. However, special care should be given while planting this plant indoors. Here are few things to consider before indoor planting of Agave:

1. The indoor-planted Agave requires bright light to preserve its peculiar form so ensure good sunlight.

2. Overwatering is the major problem in the indoor-planted Agave. Watering in a weekly interval is enough.

3. Pot the agaves in a 2:1 mixture of soil and sand.

4. Nutrient may become deficient in container planted Agave. So, fertilize during the spring season with compost tea or manure each year.

 

Types of Agave plants

Genus Agave contains about 270 species, all hailing from the deserted area near South America. Among a large number of species of agave, here we will mention only a few of them which you might prefer.
