The economy has been tough in Central Texas this summer, and a variety of little (and large) animals are flocking to residential gardens to graze. Even deer are unlikely to attack an agave, and if they don’t, we can’t think of any other animal that would. Only a few plants are entirely deer-proof. Deer browsing is influenced by a number of factors, including deer population density, climatic circumstances such as drought, and plant palatability. Plants having aromatic foliage, stiff, leathery, and/or prickly leaves, or milky latex or sap are avoided by deer. Agave americana (American century plant) and Agave univittata are two agaves on our Deer-Resistant Species list (thorncrest century plant). All of the native agaves in our Native Plant Database would be represented by them. Not only are they tough and spiky, but they also contain a very potent sap, which we are advised to avoid by wearing heavy gloves and goggles when trimming or transplanting agaves. Deer aren’t particularly bright, but it’s hard to believe they’d do something like that.
Between January and April, male deer shed their antlers. During the Summer, when the bony antlers are growing, they are covered in a delicate skin called “velvet.” The velvet withers, dries, and falls off after 2 to 4 months of antler growth, which is often aided by the deer, who rubs his antlers against tree bark. Because mating season is in the fall, the velvet is normally lost in the early autumn. So it’s possible that the damage to your agave was caused by a deer who tried to bite it and decided that if he couldn’t eat it, he’d rub his itchy antlers on it instead.
What animals eat agave plants?
The sturdy spear-like leaves that grow from the center of a rosette distinguish agave, sometimes known as “century plants.” This rosette of leaves collects rainfall around the plant’s base, providing a self-irrigation mechanism. Most agaves bloom in 15 to 30 years, despite their name. The plant devotes all of its resources to the blooming stalk before dying the following season.
Cloth, rope, needles (from the pointy tips), and thread were all made from the fibrous leaves. Native peoples enjoyed the sugary taste of the hearts (harvested shortly before blossoming) baked in underground pits and pounded into cakes that were dried for storage. Tequila has been created in central Mexico for generations from fermented and distilled agave juice. Deer, squirrels, and a variety of other animals eat the stalks, while hummingbirds and bats devour the flower nectar in exchange for pollination.
From July through September, the lesser long-nosed bats rely nearly entirely on Palmer agave as a food supply in southeastern Arizona and southwestern New Mexico. Although it was formerly assumed that the lesser long-nosed bat was required to pollinate Palmer’s agave, more recent research have shown that other animals and insects (bees, hummingbirds, orioles, hawkmoths, butterflies, and wasps) are capable of doing so. Because there isn’t much else for them to eat in late summer, the bats require the agaves more than the agaves need the bats.
What animals eat agave leaves?
Agaves, yuccas, and cactus can be badly damaged by ground squirrels, pack rats, rabbits, and mice. Rodents don’t seem to bother aloes too much. These creatures attack and destroy both adult and young plants during periods of extended drought.
Do deer eat blue agave plants?
Prickly plants, as well as those with highly scented foliage, stiff leaves, or milky sap, are often disliked by deer; but, if alternative food is insufficient, they may eat them. In hotter regions, agaves (Agave spp.) are a suitable choice. The towering century plant (Agave americana) thrives in USDA hardiness zones 9 through 11 and makes a bold statement in the garden. Smaller spiky plants, such as variegated Spanish dagger, can be cultivated alongside the century plant (Yucca gloriosa “Variegata,”, hardy in USDA zones 7 though 11). Plants in the Allium genus, on the other hand, have too strong an odor to be a deer’s first pick. Try decorative onion, which is a beautiful alternative to conventional garlic and onion (Allium giganteum, USDA zones 5 though 8).
Are agave plants toxic to animals?
When consumed, the agave (Agave spp.) plant, which grows in USDA plant hardiness zones 9 to 11, is somewhat hazardous to canines and humans. It is unlikely to kill your dog, but it will most likely cause agony and pain.
How long do agave plants 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.
Why is my agave plant dying?
The fact that agave plants dislike cold weather should come as no surprise. These plants will suffer if the temperatures go too much below freezing.
Freezing temperatures may cause agave plants to die, and the leaves will be the first to go. The leaves may begin to turn black and eventually fall off after being extremely dry.
If the freezing temperatures only stay a few hours, an agave plant will most likely recover. The plant will have major problems if the temperature remains so low for an extended period of time.
To try to protect agave plants, keep them closer to regions that can keep them warm. Having agave plants on your patio and near a warm house, for example, may help them survive cold nights better than if they were out in the open.
What is the white stuff on my agave?
Hard white spots (reply) It could be “edema,” a prevalent type of agave damage, according to insiders. Agave edema is claimed to occur when the plant’s roots absorb water faster than the stomata can release it (eg, during a hot day).
How do I get rid of agave plant fungus?
Because fungicides aren’t always successful, prevention is the greatest form of control when it comes to agave anthracnose.
- Avoid using overhead sprinklers and instead use drip irrigation or a soaker hose to water the plant. If the disease is present, never water overhead.
- Spray garden tools with isopropyl rubbing alcohol or a mixture of 10 parts water to one part household bleach to disinfect them.
- If you’re looking for new agave plants, search for disease-resistant cultivars that are healthy. Allow plenty of space between plants to allow for proper air circulation.
The quick eradication of growth with active lesions is a part of agave anthracnose treatment. To prevent disease spread, thoroughly destroy infected plant portions. Diseased plant components should never be composted.
Are cactus deer-resistant?
When their typical food sources become scarce, deer will at least try to eat anything, with try being the crucial word. In comparison to a well-fed deer, a hungry deer is more likely to take a bite out of your favorite delicacy.
Aside from that, there are several succulents that appear to be resistant to deer. Succulents with built-in defense systems, such as cacti’s spikes, fall under this category.
If you want to maintain succulents outside but are worried about deer eating them, there are a few varieties to consider. Prickly pear cactus, yucca, agave, sotol, aloe, and hens and chicks are among them.
There is a distinction to be made between deer-resistant and deer-proof. The aforementioned succulents are still edible to deer. However, there is a slim chance that these animals will eat these plants.
