Snake crops are powerful: they propagate simply, don’t want a lot water, and tolerate full solar and deep shade alike.
Nevertheless, these superior traits current a double-edged sword. It’s straightforward for species resembling Dracaena trifasciata to unfold in ideally suited situations outside… too straightforward.

A snake plant doesn’t know or care the place its designated area in your backyard begins or ends – if it has the room and sources to increase, it can achieve this if planted within the floor in an appropriate local weather.
And whereas this spreading behavior helps it to outlive, it could throw a wrench into your panorama design plan.
Having an invasive species rising in your backyard doesn’t do your different specimens any favors, both. To not point out the potential results it could have on the ecosystem at giant.
This information will allow you to handle any undesirable specimens in your panorama.
Needed background information, management protocols, clear causes to maintain these guys beneath management – it’s all coated right here.

What Are Snake Vegetation?
Previously honoring the Italian polymath and seventh Prince of San Severo, Raimondo di Sangro, all Sansevieria species have been not too long ago reclassified as members of the Dracaena genus alongside current Dracaena species, resembling D. draco and D. reflexa.
Although all species previously categorised as Sansevieria are identified generally as snake crops, all species of Dracaena usually are not.
And a few of these usually tend to develop into invasive in residence gardens than others.
Native to the tropics of western Africa and hardy to USDA Zones 9 to 12, these clumping evergreen perennials tolerate a variety of rising situations.
The eager adaptability of those species makes them implausible additions to the backyard when deliberately cultivated – or an actual nuisance in ideally suited climates after they’re undesirable.
However given a alternative, I’m positive snake crops would gladly take the recent, humid, and cramped situations of the jungles that they name residence.
Maybe that’s why they develop aggressively in equally heat, moist, and tightly-packed environments resembling what you would possibly discover in sure elements of Florida and Australia… however I’m getting forward of myself.
Snake plant species range in dimension – D. stuckyi, for instance, reaches as much as 10 ft tall, whereas D. trifasciata ‘Hahnii’ often doesn’t develop greater than six inches tall.
Basically, they flaunt evergreen succulent leaves that change in form, waviness, association, and hue, though they often don’t stray too removed from a inexperienced coloration palette.
Now and again, snake crops produce wispy, fragrant flowers which might be borne on upright racemes – particularly in fertile, sunny, and root-bound situations.
Although unfold through sexual replica is usually uncommon, as these crops don’t usually produce colourful seed-filled berries after the flowers are fertilized, rhizomatous unfold is far more frequent.
The latter, asexual replica through clones that sprout from underground, is usually the goal of gardeners who want to eradicate invasive mom in regulation’s tongue from their gardens.
In addition they make the most of crassulacean acid metabolism, a course of whereby crops preserve water by solely opening their stomata for gasoline alternate at night time, one other benefit that makes survival and unfold all of the extra possible in yard gardens and past.
An superior bunch of flora, am I proper? Minus their potential for invasiveness when planted within the floor or allowed to go to seed, snake crops are just about good.
However what’s a gardener to do after they start to overstep their bounds? Let’s have a look.
Simply How Invasive Are They?
Mom-in-law’s tongue has the potential to develop invasively from USDA Hardiness Zones 9 to 12 within the US and in areas with comparable climates that they aren’t native to elsewhere.
Two locations specifically which might be identified to endure from unwelcome takeover are Australia and Florida, and ecologists there classify its invasiveness in several methods.
Within the Land Down Underneath, D. trifasciata qualifies as an “environmental weed” within the Northern Territory, New South Wales, and Queensland, whereas the remainder of Oz labels it a “sleeper weed.”
Each are alien to Australia, however environmental weeds are widespread and displace native species, whereas sleeper weeds don’t but pose a menace to native ecosystems.
In Florida, snake crops have been launched in 1800 to be used in landscaping and hemp manufacturing, and later deemed a “nuisance” beginning in 1951, because of their tendency to exclude fascinating native vegetation. D. trifasciata and D. hyacinthoides are primarily issues within the decrease half of the state.
Sanibel Island, off the western coast of Florida, additionally suffers from snake plant invasiveness.
Two-thirds of the island is protected conservation land, and efficient administration is remitted by native codes prohibiting the planting or transplanting of D. hyacinthoides and 7 different species of invasive crops.
In response to the Florida Invasive Species Council, D. hyacinthoides is assessed as a Class II invasive, which suggests it has considerably elevated in quantity from its pre-Class II state, however has not but altered the ecological features of, displaced, or hybridized with native species to the extent of Class I invasives.
For a extra collegiate evaluation, the College of Florida’s Institute of Meals and Agricultural Sciences decided through their Evaluation of Non-Native Vegetation in Florida’s Pure Areas that D. trifasciata has a “Excessive Invasion Danger,” and its use isn’t beneficial in north, central, or south Floridian landscapes.
Why Trouble with Management?
Properly, for starters, I’m keen to guess that every one of you gardeners studying this is able to somewhat not disrupt the native ecosystem knowingly.
However even when there’s no probability of your snake crops spreading past your panorama into the encompassing atmosphere, an unchecked unfold inside your individual backyard can lead to a dense floor cowl that may stop the expansion of different, extra fascinating plantings.
As a basic rule, any specimen that you just don’t want to domesticate will hog area, water, and vitamins, conserving these sources from those that you just do wish to develop.
And whereas mother-in-law’s tongue isn’t all that thirsty, its giant leaves will certainly block daylight from reaching your smaller annuals and perennials.
Even in shaded environments the place sunlight-hogging isn’t as a lot of a difficulty, a snake plant’s root system will nonetheless take up vitamins and actual property that could possibly be going to your different backyard specimens.
Talking of root programs and soil spacing, root bindage in mother-in-law’s tongue truly spurs flowering, which probably results in even additional unfold through seeds.
Suggestions for Managing Invasive Snake Vegetation
Together with being value a pound of treatment, prevention will prevent the trouble of later elimination.
Before everything, verify your native legal guidelines and environmental rules. If they are saying which you can’t develop these guys in your panorama, then don’t.
When you have the okay to develop them, then ensure to include them inside an enclosed space in order that they will’t unfold through their rhizomes.
Pots, planters, raised beds, or plots surrounded by partitions, concrete, and/or walkways all depend as enclosed planting areas, so you might have a ton of choices!
Our information to rising snake crops indoors covers the ins and outs of container cultivation.
However when you have any out-of-bounds specimens – or their designated zone is overcrowded with them – you’ll should take away them to verify their unfold.
Because the fictional snake venom knowledgeable Dr. Steven Worth as soon as stated, “Make it quick. Time is tissue.” Venomous bites aren’t going to be a priority right here, however until you get to work shortly, these snakes are simply going to maintain on rising.
As a result of waxy coating of their leaves, chemical controls aren’t assured.
However squelch your internal pyromaniac and skip the blowtorch. Your finest guess is to bodily take away snake crops from the bottom through digging.
Dig down about two ft deep, and a few foot away from every snake plant, going across the perimeter.
Any severed rhizome fragments left within the soil can simply resprout to kind a brand new mother-in-law’s tongue, so attempt to keep away from damaging the foundation system as you dig. This will require switching out your cumbersome shovel for a small hand trowel as you get near the foundation system.
As soon as the supposed specimens have been lifted, verify for and take away any rhizomes that could be stealthily mendacity within the soil.
Residing vegetation can take root in natural refuse, so eliminate any eliminated specimens within the rubbish in case you don’t need them rising out of your compost pile, or spreading into wild lands past cultivation in your individual yard.
For those who don’t need any seeds to be unfold by animals, deadhead flower stems earlier than they provide approach to seed-bearing berries.
Instruments used for any of the above procedures needs to be sterilized beforehand – you don’t wish to unfold illness!
After you take away the snake crops, you’ll find yourself with gaping holes in your backyard the place they was. You may both fill them with soil, or put new plantings of their place.
For the latter, I’d suggest heat tropical specimens native to your native space.
Elephant ears, birds of paradise, or canna lilies could also be appropriate. Strong companions for the snake crops you didn’t take away embody colourful selections resembling petunias, marigolds, and coleus.
Undesirable specimens which have self-propagated round your backyard can be divided and potted up. See our snake plant propagation information for suggestions.
