Agaves are commonly planted in gardens in USDA hardiness zones 8b to 11 because of their drought tolerance and the visual attractiveness of their broad, spiky leaves and towering bloom stalks that can exceed 40 feet in height. Most of the time, the plants require little attention, although they do benefit from occasional trimming to improve their overall appearance. Agaves, on the other hand, dislike excessive pruning and can die back if healthy leaves are removed, so just remove spent flower stalks and any damaged or dead leaves that occur.
How do you prune a large agave plant?
Remove wasted flower stalks as close to the plant’s main body as feasible at their point of origin. To facilitate water flow, cut the stem at an angle with your pruning saw. Dispose of it in a green waste bin after breaking it up into manageable pieces.
Can you cut an agave stem and replant?
Yes, but rooting will take a long time. The longer it takes for roots to form, the larger the diameter of the stem. Furthermore, the further the cut is made from the lowest leaves, the longer it will take for the plant to root. Just below the greenest portion of the tree’s trunk, make a cut. Allow for a week of air drying before planting in dry soil in a container. Wait until fresh top growth develops, suggesting that roots have begun to form, before watering.
It’s possible to do it now, but it won’t root until early spring. Allow it to grow for a few months in a container before planting in the garden. This will allow you to get the most out of your water and nutrients for the fastest root growth. Make sure the light levels are equivalent to where it will be placed in the future. You could even put the pot there, but only after the beheaded rosette has recovered.
The more I think about it, you could just bury it a little deeper to balance the stem height with the size of the rosette in your garden. This species’ long neck is accustomed to leaning toward the light. It’s difficult to know what the best line of action is, but I wouldn’t rush to behead it unless the length is due to poor light levels. This is known as etiolation, and the sole treatment is to shorten the stem length.
When should agave be pruned?
Prune after the seeds have matured and/or spread if you want to save them for propagation or food for wildlife. Agave blossoms and then dies. After blooming or at the first sign of agave weevils, the spikes should be cut off and the plants removed.
Can I cut the tips off my agave?
To avoid skin and eye contact with the agave plant spines and sap, wear heavy protective clothing and eyewear, such as a long-sleeved shirt, gloves, slacks, and safety glasses or goggles. While the sap of some agaves is consumed, some plant saps can irritate the skin if they come into touch with it.
Using a pair of bypass pruners, cut straight across the rigid leaf tips just above the point where the soft leaves convert to hardened spines. Cut just above the thick, fleshy area of the leaves, but not through it, as this can attract pests like the agave snout weevil, who deposit their eggs in injured plant sections. The weevil larvae dig into the plant’s delicate tissue, introducing a toxic bacteria that rots the plant cells and causes the plant to decompose from the inside out.
Should you cut damaged leaves?
Is it necessary to remove dead leaves? Yes. Remove brown and dead leaves as quickly as possible from your houseplants, but only if they’re more than 50% damaged. By removing these leaves, the remaining healthy foliage receives more nutrition and the plant’s beauty improves.
How long does an agave plant live?
You never know when your heart will grow a big asparagus spear. After resting quietly in your yard for fifteen or twenty years, agave plants decide to do something unexpected. Agave plants are a common sight in Austin, Texas, where they’re positioned in front of your favorite mid-priced Mexican restaurant, stuck in a traffic island between a Bed Bath & Beyond and a Whataburger, and groomed into enormous pineapples in grandmother lawns. I had two of them in my yard and had no idea until one of them poked me in the leg.
The agave, as lovely as it is, has the ability to lull you into a state of apathy. One day, you walk past the agave, which is leaning against your mailbox like a drunk and pointing an asparagus spear the size of a telephone poll at the skies. With this asparagus thing, I’m not implying anything about European colonization of the Americas. It juts out of the heart of a languid agave like an asparagus spear, thick as a tree trunk, that could be served at a farm-to-table restaurant for gods. You say it out loud, “That’s strange.” And the guy in the neighbor’s driveway who lives in a camper van tells you, “Did you know that agaves and asparagus are related?”
The Asparagaceae family contains 200 species of Agave (genus Agave). Mexico, the southwestern United States, and the Caribbean are all home to this species. The most common type of agave is used to make tequila, mezcal, and agave nectar, among other things (a sweetener). The century plant, also known as the maguey agave, is most typically used as a landscape ornament. The leather-like leaves of the agave are distinguished by their spiky prickles. Agaves form a symmetrical rosette, with some remaining tight and spherical and others becoming floppy and awkward. An agave may grow up to 20 feet in circumference, around the size of a bouncy castle, given the correct conditions. Most are pleased to live in pots or to adorn the lawns of their grandmothers. Aside from that, agaves are a jumble of inconsistencies.
Number one: An agave is not a cactus.
Agaves are not cacti they’re a completely different type of plant from a different lineage. They’re sometimes mistaken for cacti because they’re thorny and thrive in the desert. Agaves have plump leaves that thin out and are somewhat spiky, similar to aloe which they are not. Some agave plants yield sap, which can be used to manufacture pulque, a fermented alcoholic beverage that predates tequila by millennia. Mayahuel, the Nahuatl deity of agave, used her 400 breasts to serve pulque. She had a brief relationship with Quetzalcoatl. Mayahuel, on the other hand, was not a cactus.
Number two: Agaves lie about their age.
Despite their reputation as century plants, most agaves only live for 15 to 30 years. At the garden center, opinions differ, but you might be able to extend the life of an agave by trimming its lower leaves and leaving only the leaves near the top, or the center of the rosette. Agaves, when freshly clipped, resemble over-sized store pineapples. It is up to the agave in question to decide whether or not this strategy will succeed. Once an agave has developed flower buds from its agave trunk, it has completed its transformation into a completely new plant, and all you can do now is assist the plant in getting its affairs in order. Whatever you do, you’re dealing with a plant that will outlast a couple of house cats. Take or give.
Number three: Agaves are not asparaguses.
Although the agave is a member of the asparagus family, it is not an asparagus. Agaves near death convert decades’ worth of energy into a massive asparagus death spear the size of a cell phone tower tree. The agave makes its final stand with a tremendous explosion of high-weirdness. The ordinary dinner-table asparagus, like the agave, belongs to the monocots (monocotyledons) plant group. They only have one seed leaf (cotyledon). This is a topic on which many individuals have a lot to say. Dave’s Garden provides my favorite definition:
The first leaf that develops from a seed is known as a cotyledon. Dicots have two, while monocots have only one. It’s a big thing. Some plants only have one leaf at the start of their existence, while others have two. There doesn’t seem to be enough of a difference to justify basing an entire plant classification system on. But, well, we have to start somewhere, right?
Orchids, most species of grass, palms, lilies, and the pineapple are all monocots. Long-distance relationships between Europe, Africa, and Asia are asparagus.
The only time an agave reproduces is just before it dies. Monocarpy is the process of only reproducing once blooming, setting seeds, and dying. An agave reserves all of its energy over the course of its existence, waiting for the appropriate moment to disperse its seeds and reproduce. It hunkers down, storing all of its vitality in its heart, weathering years of drought and periods of torrential rain and when it rains in the desert, it’s as if all of the sky devils decided to empty their above-ground pools at the same time. The agave then produces a gigantic, flowering asparagus spear out of its heart for its own purposes.
The agave holds a pollination sex party when the asparagus tree flowers. Bats, ants, hawkmoths, beetles, and doves that feed on nectar arrive to disperse agave pollen and seeds. The agave’s asparagus spear smashes to the ground when it dies, scattering seed babies to grow more agave plants. Or slam a Subaru Outback into a cul-de-sac in South Austin.
It’s a huge pain to get rid of a dead agave. Agaves feature thick root systems in addition to their thorny leaves. The blue-gray leaves will rot into an awkward mound of white and crumbly plant decomposition if left to rot, as if a swarm of bunniculas had an agave hoedown. Old Doritos bags appear to be attracted to dead agave mounds as well. Look for the discarded remnants in the nearest agave corpse if a teenager can find food in it. There’s a giant dead one wrapped around a cactus that’s about to die that’s also wrapped around a mailbox in my area. This same house is constantly putting out boxes of old karate trophies, as if they’re going to be stolen.
Bats and agaves are said to have co-evolved. Agave nectar is used by long-nosed bats, who are an endangered species. The pollen grains are rolled around by the bats. When they fly away to search more food, they carry additional pollen with them, allowing cross-fertilization to occur. Here’s how Bats Magazine explains it:
Mutualists describe a relationship in which both the plant and the bat gain from it. Scientists believe that this relationship evolved as a result of bats and plants coevolving, and that the dependency is so strong that the plants could not reproduce without the bats, who would starve to death if the plants were not around. This association appears to be quite sensitive to disruption.
Tequila manufacturing is one of these disturbances, as it puts long-nosed bat populations and agaves at jeopardy. Tequila is made from the heart of the agave azul, which must be harvested before it flowers. While the loss of so many century plants in my neighborhood is heartbreaking, it is also lovely since it is preventing a swarm of long-nosed bats from going hungry.
The web of life is twisted and has connections all over the place. According to our current understanding, no other planet has as much life as ours. Sure, there might be phosphorescent fish swimming beneath Europa’s freezing oceans or tardigrade-like organisms clinging to Ceres’ water-vapor eruption. If the agave’s asparagus death spear teaches us anything, it’s that life is fleeting and precious, that all living things have quiet links, and that it’s never too late to be weird.
Can you replant agave without roots?
As frequent readers know, I’m moving this week, and I’ve sworn to take my beloved ‘Whale’s Tongue’ agave (Agave ovatifolia) with me rather than leave it to the whims of fate and a new owner who might not appreciate its spiky qualities.
Agaves are normally unconcerned about being dug up and relocated. The larger the plant, the heavier it is and the more difficult it is to move. There’s a potential that the move will cause the plant to bloom as a result of the stress. This doesn’t happen very often, and when it does, it’s usually with older plants. Because Agave ovatifolia was first formally identified as a species in 2002 and commercially available only a few years later, I’m going to guess you don’t have a fully mature plant, despite its size.
The simplest solution is to dig it up and replant it in its new spot straight away, but that is probably not an option for you. You can wrap burlap around it like a tree if you can dig around it and get it out of the ground with the roots remaining in a ball of dirt. Because agaves’ roots are usually very long and not particularly dense, the dirt will most likely slip off, leaving you with a mostly bare root plant. That’s fine; agaves aren’t fussy about being bare-rooted. Trim the roots down to roughly a foot from the plant’s base and remove any dead leaves if this happens. Agaves are usually fairly easy to re-root. All you have to do now is pot it until you’re ready to relocate it and replant it which is probably easier said than done. I’d try to fit it into a 24-inch shallow (18-inch-deep) pot. You can safely remove a couple of the plant’s healthy lower leaves to get soil into the pot. Keep in mind that I’ll be impressed if you can achieve all of this without letting the plant take any of your blood.
I got a shallow, plastic tub supposed to be used as a pond liner for $12 at Lowe’s. It appeared to be an appropriate temporary containment for the large, blue whale, with a dozen holes made in the bottom. When I placed it next to the agave, though, it shriveled dramatically. Is there any way it could fit in there? But, oh well. Keep going!
To get a shovel beneath the plant, start by trimming off the lower leaves. Without having to come too near, my long-handled pruners performed a wonderful job of slicing through the luscious, fibrous leaves.
Some of the leaf fibers, however, were uncuttable and required cutting with a handsaw while leaning very close. I moved slowly and deliberately, trying to keep track of all the spines in the area around my face and neck.
I didn’t take a photograph of the next level since I was physically unable to do so. I dug all around the plant’s base, hoping to find a good-sized root ball. I tried levering the plant up with the shovel once I’d dug deep enough to get under and cut the main roots. There’s no way. The agave appeared to be as heavy as a whale and refused to budge.
Sweat was dripping down the inside of my goggles, I was cleaning my sweaty face with gloves soaked with agave juice from chopped leaves, and my face was immediately stinging and itching like crazy. As I hurried inside to obtain a damp towel and wipe my face with soap and water, a few choice remarks escaped my lips. Okay, there’s no harm done. Take a clean towel outside to mop up the puddle I’m about to become in another 10 minutes.
I excavated a narrower circumference around the agave and attempted to re-lever it. It swayed. I dug some more and levered again, feeling encouraged. It began to raise on one side, then the other. Success! However, how do you take it up and place it in the plastic tub?
The issue about agaves is that they don’t come with handles, which is obviously obvious to everyone else but wasn’t to me. You can’t bend in to lift the root ball without risking a thousand-point death penalty. Because the bottom leaves are coated with thorns, you can’t grab them to pull them, and they’re also quite delicate, snapping like a Saltine cracker if you apply any pressure. Because they’re so dense and heavy, you can’t pick them up with your shovel. I couldn’t simply ignore the mess until my spouse returned home to assist. What if a potential buyer contacted right now to schedule a showing? I sat and pondered the hauling experiences of my fellow garden bloggers, and one in particular came to mind.
I decided that sliding it would be simpler if it was in the tub, so I pushed up with the rope on one side, then the other, wedging the tub more under the agave with each pass. I was poked in the knee a couple times, but no blood was lost!
It’s not over yet! I needed to put the potted agave on a wheeled dolly now. I’ll leave the intricacies of levering, lifting, and avoiding unpleasant spikes in the face to you. I eventually triumphed, and the agave is now happily relaxing in the back yard, waiting for the next big thing. I just hope I got enough of its roots to save it.
Update: If you’re wondering if the agave grew back, the answer is yes. Continue reading to learn about Moby’s later exploits and final natural death and resurrection! (Yes, I’ve given this agave a name and a special place in my heart.)
Can you cut cactus and regrow it?
Cactus plants may produce new plants by cutting off portions of the original cactus. The method of cutting is determined on the cactus’ shape. These segments are often used to propagate varieties with segmented leaves or stems. Cactus plants that develop little young plants around the base of the parent plant, such as barrel kinds, are one example. One of these smaller plants can be removed and grown into a new cactus. Removing the cutting and correctly transplanting it protects the original plant while also ensuring that the new cactus grows well.
Why are my agave leaves turning yellow?
Agaves are desert animals that can survive on very little water. They don’t require as much water as other plants that flourish in diverse climates.
The container will flood if the soil is unable to absorb the water effectively. It can produce root rot, mushy stems and leaves, and yellow or brown tips on the stems and leaves.
