Agave Plant Care & Growing Guide

Is water becoming a concern in your water-guzzling garden? Then, an ideal solution is to add some Agave plants. Interestingly, there is a wide selection available that we will discuss later on.

But today, we will look at how to care for Agave plants that are pretty drought tolerant.

What Are Agave Plants?

The Agave is part of the Asparagaceae family comprising over 270 species. The lush foliage is part of the Americas and is found mainly in the Caribbean and Mexico. One thing is the succulent plants give a gorgeous ornamental display.

People use foliage for food, fiber, and medicine as the leaves, flowers, and stalks are edible. The most commonly grown Agave species is the Agave americana. Gardeners refer to the century plant as the plant takes a long time to bloom.

Furthermore, mature plants develop a thick stem that reaches out to the sky, and after a few years, you see this tall flower stalk reaching out. The plant naturally forms a rosette shape with leaf margins, and the bottom leaves protect the plant roots.

Agave has leathery leaves forming rosettes that grow from six inches to 20 feet in diameter. The leaves vary in size, texture, color, and shape. You find teeth with a stiff tip and a sharp spine at the edges.

Most plants have projections, but some have unarmed foliage. When it matures, you notice a stalk growing from the center producing long-lasting flowers.

The tubular blooms vary in color from yellow to green and white and produce fruit. The maximum growth of the plant and its gorgeous flowers can be seen in its natural habitat.

Hence, treating them as outdoor plants in USDA zones 8-9 would be the best way to replicate their natural habitat.

How to Grow Agave Plant

So, why should you grow an Agave plant? There are many reasons, but the first one is that the leaves are eye-catching and displayed with curious markings. Some have curled threads, while others have striped leaves.

Another fantastic thing is that it looks great on the patio and is considered fire-retardant. Furthermore, it is a drought-tolerant species.

Main Growing Requirements

  • Most agaves prefer well-draining soil that is rocky or sandy, like a cactus mix.

  • Developing a beautiful flower spire requires full sun for at least six hours daily, even if it is slow-growing.

  • The best time to plant the agaves is in the growing season, in early spring or early fall.

  • It prefers a slightly acidic to neutral soil and does not use fertilizer.

  • It does not grow well in high humidity and only water sparingly.

  • Century plants grow well indoors in containers.

A note of warning

The Agave americana is considered invasive in other parts of the world. The best to prevent them from spreading is to remove the agave pups when you see them.

Soil Condition

When considering other succulent plants, you need to pay attention to the soil you use. But when it comes to the Agave species like Agave attenuata, Agave americana, Agave parryi, they all have weak root system.

So, when potted, your plants are vulnerable to crown rot—the warm-climate varieties need ample drainage. We recommend using cactus soil that is grainy, light, and sandy. These will help established plants to have well-draining soil, as dense soil will encourage fungal root rot.

Agave Indoors Light Needs

We recommend keeping your plant in full sun with partial shade throughout the day. Also, agave plants love being in a sunny window if treated as an indoor plant.

But the best is to take your desert beauty outside in summer to bask a bit but not too long to prevent sunburned leaves. The best is to place your plant in midday shade.

Still, if you have no alternative, using artificial light to care for Agave indoors is best.

Agave is Drought Tolerant

So your plant arrived from the nursery; what should you do? First, we recommend watering the plant three times a week. Doing this helps establish the plant’s root system. After this, you can ease off with the watering.

You can then water your plant once a week to prevent fungal root rot. The rule of thumb is to let the soil completely dry before you water again. We recommend looking at another soil mix, like a cactus, if the ground retains moisture.

Temperature and Humidity Necessity

The Agave loves warm temperatures up to 120°F (50°C) even if they are slow growers. When in direct sunlight, they thrive. But they can also tolerate temperatures as low as 50°F (10°C).

We recommend bringing it inside your home if you live in an area known for cooler temperatures and frost. Speaking of humidity, your plant is fine with normal humidity levels. But if grown inside, expose them to fresh air with good circulation.

Fertilizing

The strange thing is when you grow Agave plants in the garden; it does not need feeding. Feeding your succulents boosts the bloom; you do not want this to happen anyway.

The reason is that the mature plant dies after it grows a flower stalk, so you do not want to encourage flowering. So instead of feeding, you can provide the plant with fresh soil.

If you wish to add balanced plant food, be sure to propagate the plant first.

Agave Plant Propagation

Reproducing new plants can be done using the Agave seed or by dividing pups. This is an essential part because Agave plants die after flowering and will allow you always to have young plants available.

Using Offest

A large agave produces pups around the base you can remove. You can do this at any time.

  1. Find the pup and root connection to loosen them from the parent plant.

  2. Dig them up and leave enough roots intact to remove them from the larger plants.

  3. Place the offsets in the shade away from bright light for a few days to callus.

  4. Place the offset in a succulent potting medium with a small container and drainage holes.

  5. Moisten the soil and keep them at the soil line when backfilling with soil.

  6. Place them in a warm spot in bright sunlight and water when the soil is dry but not soggy.

Then transplant them into the garden after a few weeks.

Planting Agave Seeds

Seed sowing to grow Agave is not tricky, and they develop within a few weeks.

  1. Take a shallow container with drainage holes and fill it with a seed starting mix.

  2. You can gather seeds from the parent plant or buy them online.

  3. Scatter the seeds on top of the soil and, depending on the variety, ensure that the seed does not need light to germinate. If the light is not required, cover them.

  4. Moisten the growing medium and cover the container with plastic wrap.

  5. Please place it in a spot with bright indirect light, and once seedlings emerge, remove the wrap.

  6. You need to acclimate the seedlings for growing outside before planting your new plants outdoors.

USDA Growth Zone

USDA growth zone map

Most Agave plants can grow in the USDA hardiness zones 8 or 9 to tolerate frost somewhat. The Agave parryi is more of a perennial that thrives in zone 5.

Repotting Agave Plant

Okay, your mother plant has matured, and while they have shallow roots, there comes a time when you need to repot them. The important thing is the potting medium needs to be stable for the Agave roots to anchor.

You can use an unglazed clay pot as it helps to evaporate moisture through the walls. Start by watering once a week in the summer and monthly in winter. The best time to transplant is in spring or summer.

Agave Varieties and Similar Plants

We mentioned before that the varieties in the Agave species are enormous. Here are some of them you will want to add to your collection:

Agave attenuata

Agave attenuata

It is a popular spineless species known as the dragon tree or foxtail. You’ll find it growing up to five feet tall and more expansive than most of the other plants.

Agave parviflora

Agave parviflora

The leaves of this plant have white markings, and the filaments curl to give it a hairy appearance. It does not grow very high, only six inches. Still, it only blooms every eight years with green flowers.

Agave tequilana azul 

Agave tequilana azul

The Blue Agave is known for its tequila production and is an attractive plant in your yard. The foliage grows up to six feet tall and blooms yellow flowers.

Agave victoria-reginae 

Agave victoria-reginae

When the plant matures, you see it with broad cup leaves that form a dome. But, unfortunately, it only reaches a foot high with cream flowers after 20 years.

Agave Diseases & Pests

If you get one of these plants, it is one hardy foliage. But as with most garden plants, there are things to look out for:

Root Rot

A common problem is root rot and found with potted variants. So, control the soil moisture to prevent this from happening. You notice the base discolored if crown rot appears and the leaves pull away from the stem.

Anthracnose

If you notice an orange or red lesion over your Agave, it is the cause of anthracnose. The best is to remove the infected areas to prevent spreading.

Agave Snout Weevil

Agave snout weevil is another problem caused by wet soil. Again, it would be best if you acted fast to treat them with an insecticide in spring or use optimal soil instead.

Underwatering

You can under-water your Agave, which is noticeable during growth, leaving brown spots on the leaves.

Other concerns are freezing temperatures depending on your species, while it can get sunburn as well.

Frequently Asked Questions

When growing Agave outside the hardiness zones, it is best to bring them indoors in colder climates. Luckily these are slow-growing plants, and you can place them in a sunny window out of cold drafts. Only water them enough to keep the leaves plump.

The blooming period is up to four months and starts as a giant central flower spike with blooms that release seeds. As a plant matures and develops a flower, it dies.

Once the flowers develop seed pods, the plants die, and the large central stalk will flop over and will need removing with a handsaw. If you are lucky, you will have offsets or bulbils found at the main stock you can twist off to replant.

It is a sign of the agave snout weevil but can result from incorrect watering. Overwatering can cause this, and best to allow the soil to dry between watering.

Overwatering can cause the leaf margins to turn yellow, but it can result from insufficient sunlight.

The Agave looks like an aloe, as both tolerate dry to warm climates. Still, both belong to different families, as aloe is native to Africa and Agave to America.
