What to Do With Agave Stalk (After Flowering)

Agave is a popular plant in landscapes and gardens. Some species are also grown in large farms for food and fiber purposes. This succulent is known for its pointy thick leaves in a rosette pattern. When blooming, agave also produces a very tall stalk where flowers form.

The flowering stalk of agave is indeed long and you can actually wonder what to do with it. Like hens and chicks, flowering signals the end of the plant’s life cycle. Agaves flower only once and they die. This happens when the plant has produced numerous suckers that grow into new plants.

Various types of agave plants have different growth rates. In most cases, agaves will take between 10 to 20 years to bloom during spring or summer. If you haven’t seen them blooming, you can actually be fascinated with their flowering aspects.

What to do with agave stalk

Agave flowering stalk height can range from a few feet to several meters.  It bears numerous small tubular flowers along its length and sometimes bulbils that are clones of the mother plant. The height of the stalk is essentially to discourage predators from eating the blooms.

The flowers of the agave produce sweet nectar and they commonly attract pollinators such as bats, bees, and birds. I love observing this wildlife in my garden. As the flowers mature into seeds, you can harvest and use them to propagate new agave plants.

Once the flowering process is complete you might choose to cut down the stalk so the plant can direct energy on the new offsets at the base. However, this won’t stop the flowering rosette from drying off but it can help to slow down the process.

What to do with agave pups

One of the primary reasons people pay attention to agave pups is for propagation. These small offsets that grow from the suckers at the base of the plant can be carefully separated and replanted to grow into new mature plants.

Before you do anything, wait for the pups to grow large enough and establish their own root system. Gently remove them from the parent plant using a clean, sharp knife. Ensure the offsets have as many roots as possible.

Transplant your pups into their own potting soil, water them thoroughly, and place them in a location with bright indirect sunlight. Make sure to use a well-draining potting mix and a pot with drainage holes. Once the pups adapt to the new growth conditions, treat them as mature agave plants.

How to care for agave plants indoors

Under the right care, agave is also a great houseplant. Here is how to care for your agave plant indoors.

Light 

Agave is a full-sun plant, meaning it requires at least 6 hours of direct sunlight, especially during the morning hours. The plant may benefit from shade during the intense afternoon sun in hot climates. A south-facing window is a perfect spot for growing agave plants indoors.

If your agave plant is stretching and growing tall with widely spaced leaves, it’s likely not getting enough sunlight. You can relocate it to a sunny spot or add some artificial grow lights to the room where the plant is growing.

Soil type

As said, agave prefers well-draining soil with acidic to neutral pH. Use potting mix formulated for cacti or succulents when repotting or potting the agave plant. Poor drainage or excess water in the soil can lead to root rot and other fungal issues that may kill the plant.

Watering

Agaves are succulents and they don’t need frequent watering. Allow the soil to dry out completely between your watering sessions. During spring and summer, water thoroughly when the top inch or two of the soil is dry. Reduce watering in the cooler months (fall and winter).

When soil is waterlogged, the roots are deprived of oxygen, which makes them die and rot. Plants afflicted may die within a short period of time. So, there is need to act urgently if you suspect root rot. Overwatered succulents must be repotted in a fresh soil mix.

Temperature

Most agave species are adapted to warm and arid climates. They thrive in warm temperatures, 60 and 90 degrees Fahrenheit but may need protection from extreme heat. These plants are generally not frost-tolerant, so if you live in a colder climate, consider bringing your agave indoors.

Humidity

Agaves prefer climates with low humidity. So, the plant is fine in average household humidity levels. Plants grown in high humidity levels may experience crown rot and other fungal problems. So don’t mist the agave plant when the air feels dry or place it in a bathroom.

Fertilization

Agaves don’t require heavy or frequent fertilization. You can feed them with a diluted, balanced, liquid succulent fertilizer during the growing season about once every 4-6 weeks. Don’t overfeed or fertilize in the fall and winter when the plant is dormant.

Pruning

Agave plants generally don’t require regular pruning. You may just remove dead or damaged leaves. Use a clean, sharp knife or a pair of shears to cut those dead or damaged leaves at the base of the plant. Be cautious of the pointy tip and the sharp edges of the leaves.

Repotting

Agaves are slow-growing plants and usually don’t need frequent repotting. However, there’s need to repot the plant in a slightly bigger pot when it becomes too large for its current pot. Make sure to use a well-draining fresh soil mix and a pot with drainage holes.

Common problems

Agaves are pretty resistant to pests and diseases, but sometimes the plants might get affected by common succulent pests such as mealybugs, aphids, snout weevils, and other scale insects. Regularly monitor the plant for any signs of infestation and treat as needed. You can use insecticidal soap or neem oil.

Overwatered agave plants are also susceptible to root rot and other fungal diseases. A soft and mushy base of the plant is a sign of advanced root rot. Overwatered succulents can be saved by repotting them in fresh well-draining soil mix.

Agave plants will show various signs of distress when everything is not well. Leaves drooping, yellowing or browning can indicate overwatering, underwatering, or other issues with soil drainage. Leaf discoloration can also be a sign of a pest or disease problem.

Final Thought

Agaves are fascinating plants to add to any space including landscapes and gardens. When blooming, they produce a long flower stalk. You may cut this stalk or leave it to disintegrate naturally after the blooming. Pups can be transplanted and cared for to mature into new plants.
