Except for the east central counties, prickly pear cactus can be found across the whole state of Illinois. It thrives in sandy soil, dry plains, and bluff tops. From May to July, flowers are produced. Opuntia fragilis, a species of prickly pear cactus, is critically endangered in Illinois.
A cactus can grow in the Midwest.
As odd as it may seem, it is possible to grow cacti outside in the Midwest as long as you are aware of the specific conditions cactus have.
Cacti need a lot of good drainage. Heavy soils, like the usual clay soils of the Midwest, retain water, which results in root rot and plant mortality. Healthy growth is encouraged by planting on raised beds with permeable soil or on berms. The drainage that cacti require to survive should be provided by a soil mixture that has equal proportions of soil, sharp sand, and gravel or pumice. Be aware that good drainage applies to the entire bed, not just the immediate vicinity of each plant. Water will likely collect around the roots if you merely make changes to the planting hole since the clay soil around it will keep it in place.
Cacti require direct sun. The majority of cacti species need at least six hours of sunlight per day in order to thrive outside, both in the summer and the winter. During the chilly winter months, placement adjacent to south or west-facing walls or next to cement sidewalks can give some useful reflected light and heat. However, keep in mind to take into account how much sunlight your bed will receive during the winter when the sun is lower in the sky when determining where to put it.
Cacti must be planted in the late spring when there is little possibility of a hard frost. When cacti are planted in the middle to end of April, they have time to develop robust root systems that will maintain the plant in the event of a difficult winter.
Because their roots are shallow, cacti are readily harmed. Cacti shouldn’t be disturbed after planting. The shallow roots can be protected and weed competition reduced by using a pea gravel or rocky ground cover.
Cacti grown in the Midwest must be hardy to freezing temperatures. About a dozen different cacti species, each with a number of lovely variants, can withstand temperatures as low as 0 degrees Fahrenheit. Four species that are particularly well-suited to Kansas City and the surrounding areas have been included.
Can cacti be grown in Chicago?
Lawns are becoming brown and there is no rain. Experts advise residents in the Chicago region to let their grass fall dormant and use their water on more delicate plants, like trees, but some people find it difficult to give up on the appearance of a lush, green lawn.
The hot, dry weather wouldn’t be a concern for you if you were like Gary Janowitz of Chicago’s Northwest Side. They would adore it, and your front yard would be covered in prickly pear cactus with vibrant yellow blossoms.
The better they perform, according to Janowitz, the hotter it is. You won’t have any issues if the city ever says, “You can’t water.”
Opuntia humifosa and Opuntia fragilis are two varieties of the prickly pear cactus that can survive in the Chicago metropolitan region and even as far north as Canada. (One Web page is owned by a fan of prickly pears who cultivates them in northern Denmark.)
Janowitz is unsure of the species to which his cactus belong. He planted them outside the house where he has spent nearly all of his 52 years after digging them up from a friend’s yard in Arizona 20 years ago.
He claimed that throughout the cold, they completely shrivel up. He nearly threw away his two dejected-looking plants the first year. But in the spring, they grew larger, began to produce offsets, and eventually exploded with flowers. Now, divided by expanses of red rock mulch, they wander aimlessly throughout the front yard. He predicted confidently that they would take over everything, despite the fact that he has managed to grow cattails, bachelor’s buttons, grapevines, and coreopsis in other parts of his yard.
You could always eat prickly pears if you found yourself inundated with them. The Internet is rife with recipes for prickly pear jam, salsa, salads, soups, and other delicacies. All species are edible and a staple of Mexican cuisine. They are slightly acidic with an asparagus-like flavor.
When visitors ring his doorbell and inquire about his remarkable front yard, Janowitz enjoys answering their questions and generously gives away young plants or entire plants. He advises wearing leather gloves and keeping an eye out for little children because the main negative is that the cactus are, well, prickly.
They require full light and dry, lean soil like all cactus do. Too much water is harmful to them, according to Janowitz.
Not just prickly pears enjoy the hot heat that is grabbing Chicago gardeners by the throat. According to Kate Sadowski, the horticulture in charge of the cactus greenhouse at the Chicago Botanic Garden in Glencoe, many succulents are at their finest at this time of year.
A vast category of plants known as succulents often have thick, fleshy leaves that can store water for extended periods of time and a strong skin to keep it in.
Succulents include cacti. Succulents can spend a long time without watering and flourish in the summer heat stored and radiated by rocks or sidewalks, conditions that will fry many other plants. Succulents are native to sunny, dry, rocky locations.
Yucca filamentosa, with its sword-like leaves and late-summer white flowers, is a succulent that can withstand Chicago’s winters. Sadowski like the cultivar ‘Bright Edge,’ which has a gold streak surrounding each leaf.
Another excellent option is any of the several species of the alpine genus Sempervivum, which have rosettes of spiraling leaves. Their widespread name, “hens and chicks,” alludes to their propensity to sprout new, tiny plants provided their growing environment is suitable for them—dry and preferably rocky. There are many sizes and hues, ranging from green to crimson.
Sedums are yet another great choice. The upright sedums, which are popular among gardeners for their colorful flowers, include the virtually ubiquitous Sedum spectabile ‘Autumn Joy’. Sadowski noted that there are numerous low-creeping sedums with late-summer white or yellow blooms and foliage that is tinged with blue, purple, and scarlet in addition to green.
Due of their durability, love of the sun, and tolerance of drought, creeping sedums are frequently utilized on green roofs, such those at the Oak Park Public Library and the Chicago Center for Green Technology.
Succulents are an excellent option for pots since you can manage the soil and keep it thin, free-draining, and wet. They can withstand the hot concrete floors and drying winds that are frequently encountered on apartment balconies. Just make sure they are set up in the sun and not in the balcony upstairs’ shadow.
When Chicago’s weather swings to the other extreme, the largest threat to cacti and other succulents is: They struggle in cool, wet summers like the one we had last year, according to Sadowski.
But despite this, Janowitz’s prickly pears have thrived. He runs a construction company, manages car donations for the Y-Me National Breast Cancer Organization, rescues abused or abandoned tropical birds, restores a 1949 maroon Rolls-Royce, and sails his 45-foot yacht from Belmont Harbor. When he’s not doing any of those things, he’s usually in his front yard rearranging his cacti. He declares, “I play a lot.”
Cacti Can they endure the winter?
We’ve compiled general maintenance advice to make sure that your cactus, no matter what kind, will survive the upcoming winter.
- Don’t water your cacti excessively. Many cacti can go the entire winter without getting any water, therefore you can let nature hydrate your plants by getting rain. Or, to avoid causing your plant root rot if you keep it indoors, stick to a watering regimen that is at most monthly. Be cautious while watering outdoors because water might freeze and harm your plant’s roots and stems.
- Your cacti will benefit from a rock mulch. Adding mulch to your cactus soil warms the soil for your plants and helps you avoid overwatering. If you maintain frost-tolerant cacti outdoors, you can protect them from the cold by covering the soil with a layer of small rocks.
- Don’t feed your cacti fertilizer. During the chilly winters, a nitrogen-rich fertilizer can be particularly detrimental to young, delicate plants. For the spring and summer, postpone fertilizing your cacti.
- Give your cacti the most light you can. Your plant won’t likely receive the greatest light if you bring it inside. If feasible, place your plant beside a southwest window and add grow lights if you need more light.
Which U.S. states have cacti?
Only a few hardy species of opuntia and escobaria are present in almost every US state and southern Canadian province, although they are much more common in the southwest’s arid areas. Cacti are prevalent in six US states, including (roughly) the following: Arizona (83), California (35), New Mexico (56), Nevada (26), Utah (34) and Texas (91).
The Sonoran, Chihuahuan, and Mojave deserts correspond to the lower elevations and southernmost places where the densest populations can be found. The hottest part of the Sonoran Desert in southeast California and southwest Arizona also has a relatively small number of species for the same reason. The best places to see cacti are south and southeast Arizona, south New Mexico, and far west Texas, especially in the Big Bend region. Of these three, the Mojave has somewhat fewer species due to its low rainfall.
The golden cereus, Munz’s cholla, coastal cholla, chaparral prickly pear, and San Diego barrel cactus are just a few of the rare cactus species that grow in California’s far southwest, close to San Diego, and down the coast into Santa Barbara. These can be seen in locations like Torrey Pines State Reserve, Santa Monica Mountains National Recreation Area, and Cabrillo National Monument, but the majority of California species are found in the southeasterly deserts, specifically in Mojave, Anza Borrego, Death Valley, and Joshua Tree National Parks. Joshua Tree is particularly fruitful because it is located on the border of the Sonoran and Mojave deserts, and as a result, has plants typical of both.
Arizona has two National Park Service (NPS) locations dedicated to particular cacti: Organ Pipe Cactus National Monument in the far south, bordering Mexico, and Saguaro National Park on either side of Tucson. With approximately 30 species, some of which are fairly rare (like senita), this latter area is one of the best cactus places in the entire state. Other cactus-filled desert preserves include Kofa NWR, Sonoran Desert National Monument, Cabeza Prieta NWR, Ironwood Forest National Monument, and Agua Fria National Monument. Several small state parks, like Catalina, Sabino Canyon, Lost Dutchman, and Alamo Lake, also provide an excellent introduction to the local flora. The region in the far southeast between Nogales and the Chiricahua Mountains, which is where certain plants from the adjacent Chihuahuan Desert may be seen, as well as some that are significantly more frequent over the border in Mexico, has the most uncommon species, except from Organ Pipe NM. Cacti, however, are abundant throughout the state; for instance, the Canyon De Chelly National Monument is home to 12 different species. A few areas in the north also contain some extremely rare species, such as the pediocactus bradyii in the Marble Canyon region and the sclerocactus sileri on the Kaibab Plateau. Visit a botanical garden, like the Boyce Thompson Arboretum in Superior or the Arizona-Sonora Desert Museum west of Tucson, if you want to observe a wide variety of plant species all in one spot.
Around 20 different varieties of cacti can be found in Nevada’s far south, on the edge of the Mojave Desert. These include the hills that border Lake Mead and Lake Mohave, the foothills of Mount Charleston, and Red Rock Canyon National Conservation Area. The most prominent species are the Engelmann’s hedgehog cactus, California barrel cactus, many headed barrel, five different varieties of cholla, and several opuntia. The Great Basin Desert covers the rest of the state, which has fewer cacti but still contains a few very unusual species (sclerocactus).
The majority of the state of Utah is covered in cacti, including the Colorado Plateau, the Uinta Basin in the northeast, and low-lying areas of the southwest (on the edge of the Mojave Desert). The well-known national parks (Arches, Capital Reef, Zion, and Canyonlands) are each home to more than a dozen species, and Utah contains about six forms of cactus that are unique to the US. However, there is no one optimum spot (sclerocactus and pediocactus species).
Over 50 cactus species can be found in the Chihuahuan Desert, which makes up the southern third of New Mexico. These species can be found in places like Oliver Lee Memorial State Park, the Carlsbad Caverns National Park backcountry, and (in a botanical garden setting) Living Desert State Park in Carlsbad.
With around 100 different cactus species, Texas is the state with the most. The majority are found along the Rio Grande, close to the Mexican border, particularly in the Big Bend region, in Big Bend National Park and Big Bend Ranch State Park. In particular, the species of coryphantha, echinomastus, and escobaria are at their northernmost ranges on this terrain. In the far south, in the area of Brownsville, there is another cluster of rare species. Cacti can also be found in the Davis Mountains/Fort Davis, Guadalupe Mountains, and Black Gap WMA in the Chihuahuan Desert.
Cacti can be grown outside in Illinois.
From May to July, flowers are produced. Opuntia fragilis, a species of prickly pear cactus, is critically endangered in Illinois. It can only be found growing in severely arid settings in Jo Daviess County on federally protected territory.
