“When the pups pop, get them out while they’re little.”
That’s good advice from Mr. Smarty Plants, a collective of volunteers who’ve answered thousands of questions posed to the Ladybird Johnson Wildflower Center over the years. The guidance would have come in handy before I planted several Agave americana more than a decade ago around our ranch house along the Llano River. Their blue-green fleshy leaves, exotic profile and reputation for low maintenance in brutal Texas summers seemed a perfect match for the rocky caliche soil and lack of water at the ranch.
But since we only visit the property every other weekend, some times less, my agaves became a nuisance. Too often I was absent. I failed at plant management. As Mr. Smarty Plants advises, thinning the pups early, while they’re manageable and have shallow roots, is imperative to avoiding an ornery agave cluster. I ignored the agaves entirely for more than a decade. The result? Several mean agave forests that pricked and poked anyone who dared approach.
Let there be no mistake: Agave Americana deserves our respect. The plant is a case study in self-reliance, asking for NOTHING in exchange for its reliable growth and eventual stunning presence. It demands no supplemental water, no fertilizer, no pruning, no prissing. It lives a dramatic semelparous life–that is, it enjoys a singular episode of reproduction. Then it dies.
With a lifespan between 10 and 30 years, the agave shoots one dramatic stalk yards into the sky. The resulting candelabra-like branchlets sport clusters of yellow flowers. Hummingbirds and bats love this pollen trove. Agave americana, technically native to Mexico, also is found in South Texas. Climate change inevitably will extend its range north.
Dr. Kelly Lyons, a grass expert at Trinity University, suggests the plant be put on the “watch list” as potentially invasive. It’s already been labeled unwelcome and invasive in sand dunes, where it overwhelms all competitors. Left to its own devices, the plant dominates, its rhizomes and pups forming dense communities around the mother plant. Each one has its own set of needle-tipped leaves and serrated blade-like fronds.
I stupidly imported Agave americana to our ranch a dozen years ago. I planted one each on either side of our front gate, thinking they would “welcome” visitors with their dramatic poise. Others I plugged in around the house, some along a much-used trail and a couple along our switchbacked main dirt road.
Quiet and understated in their youth, the mature agaves seemed daunting. Their passel of pups defended each mother plant like a thorny army. Nothing could be less welcoming at our front gate than getting stabbed by these mean-spirited cacti. Needle-nosed agave fronds prickled and poked whoever was assigned to lock or unlock the gate; their barbed leaves snagged on your shirt and skin, often leaving a sticker behind.
I had been stabbed one too many times. I decided to tackle the out-of-control succulents, which by this time, stood taller than my five-foot-six-inch frame. Leather
gloves, long sleeves, thick jeans, a sturdy hat and glasses became my agave fighting uniform.
I started with a shovel on one four-foot specimen behind the house. Approaching the plant was practically impossible. The gnarly agave colony fended me off, aggressively protecting its mama with their intertwined roots and serrated leaves. As Mr. Smarty Plants says, agaves self propagate via rhizomes, sending shallow-rooted baby plants all around the base rosette. This helps absorb water in the dry climate in which it thrives. The roots become intertwined, knitted together like an impenetrable quilt. As dead agave blades die and dry out atop them, a sinewy mulch results. A shovel cannot penetrate the fibrous mass.
Intrigued by this seeming fortress surrounding the agaves, I researched and learned that the thick agave leaves, plump with water, also contain stringy sisal fiber that native peoples and later Westerners used to weave baskets, rugs, ropes and blankets. Cutting these sinewy leaves to gain access to the soil to dig up the root becomes a separate challenge requiring sharp shears, a knife, nippers or a coba, a special tool from Mexico that a cactus grower friend supplied to us. Some of the fleshy leaves approach a half-foot girth at their base.
Frustrated, one day I convinced my older son Nicolas to get out the chainsaw. Even though we both wore long sleeves, hats and sun glasses, the agave juice spattered on exposed skin and caused painful welts and blisters that lingered for weeks. Nicolas had an allergic reaction that also caused a rash.
Then I tried setting the agave on fire using kindling and later charcoal fire starter. Keeping the fire alive was a challenge given the agave’s high moisture content–like burning a watermelon. Eventually, the flame caught. The plant literally shed tears as water drooled down the sides of its sword like leaves. A sad sight, but I still had to dig the root rosette up with a shovel.
I even considered herbicides, but the mass of the plants would require such enormous doses, that just seemed wrong.
Finally, an experienced landscaper suggested I wrap a chain or towing strap around the plant’s base, attach it to a trailer hitch or truck axle and pull it out by its tap-root. This seemed like a brilliant idea. After clearing as many baby agaves as we could to gain access to the base, my friend Kelly and I wrapped a chain around the rosette and attached it to my Toyota 4Runner. With four-wheel drive engaged, I stepped on the
gas and the agave released its grip on the rocks and earth holding it in place. We dragged the plant to the “agave graveyard’ on the karst watershed where it could not make contact with soil. Like its thorny sibling prickly pear, agave is famous for resprouting if any of its greenery touches the earth. Experts caution not to add it to the compost pile, either. It will quickly take root.
As a gesture of my respect for this plant, we’ve allowed two specimens to remain on site. We await their century plant spurt, the year when these mighty agaves will shoot their reproductive stalks skyward and grace us with pollen powdered yellow flowers that will attract bats and hummingbirds. In the meantime, we manage the plant aggressively, snipping its hefty mature leaves with the coba, and clearing the pups regularly.
Once these agaves springs their seeds, we’ll shut down agave production on the ranch.
