If you live in a region where the winters are exceptionally severe or if you are unable to protect your cactus plants from the cold, you can bring them indoors to keep them warm.
Consider lighting conditions inside your house
Adequate illumination is one of the main issues with growing cactus plants indoors. When you decide to move your cactus indoors for the winter, it can often be difficult to find enough illumination for them.
Your plants will require enough light indoors to live as they are used to being in the sun. Find a reasonably sunny or bright area in your home, and place them there.
South-facing windows are the ideal location.
To keep your plants healthy if there isn’t a bright location nearby, think about using artificial lighting.
Clean plants of dirt and debris before moving them indoors
Make sure you remove all the dirt and debris your cactus plants may have gathered from being outside before bringing them inside.
When left outside for too long, your plants will always have pebbles, tiny twigs, and filth. Remove any unwelcome weeds that may have sprung up in the pot and gently wipe the dirt off the spines.
Before bringing your plants indoors, clean them to aid with photosynthesis. Remember that by bringing your cactus inside, you are already reducing the amount of sunlight it receives. Therefore, having dusty plants will just prevent the plant from receiving the meager quantity of sunlight that is available.
Consider temperature and humidity
Consider tweaking your thermostat to give cooler nighttime temps if you have a furnace installed. Aim to keep interior temperatures from getting too warm.
In order to prevent the plant from experiencing a “shock,” make an effort to maintain cooler temperatures at night. Plants planted close to a vent or another heat source run the risk of dying.
Although many types of cactus don’t mind being dry, if you discover that your interior environment is too dry for your plants, install a humidifier or try placing a pot of water close to the plant to assist add the essential humidity to the air.
- Generally speaking, avoid fertilizing your cactus during the winter. These plants don’t require fertilizer because they don’t actively grow throughout the colder months.
- Also, you don’t need to water your cactus plants as frequently as you would in the summer heat. Use only a small amount of water, and before adding more, always check the potting mix for moisture. Always check that the potting soil is entirely dry in between waterings.
What are cactus used for in the winter?
Cacti and succulents are excellent low-maintenance plants that add color to the home even on the gloomiest winter days. They provide aesthetic appeal to any table or windowsill with their unique forms and textures, and with proper care, they’ll last the entire long, cold season.
Cacti and succulents are suitable indoor plants all year round. Plants simply only a little light and sporadic watering during the winter. By the time fall arrives, the majority of cacti and succulents have gone dormant and will no longer grow as the weather and light conditions change.
5 Techniques for Winter Cactus and Succulent Care:
1. Plant your dormant plant in a location where it will flourish to make your cacti or succulents happy. During the winter, succulents require less light and can also tolerate indirect light. Make sure your plant receives at least three to four hours of bright light each day for the best results. Locations are happiest close to windows that face south or east.
2. Sandy, well-drained soil is best for growing succulents. Give your plant the nutrients it requires by using Espoma’s cacti and succulent mix. Make sure containers have drainage holes to allow extra water to drain because succulents can’t tolerate excessively moist soil.
3. Set the thermostat. Few succulents can withstand temperatures that are much colder than 50 to 55 degrees.
4. Succulents require deep watering, although they won’t need as much as they do during active growth. Use little water and only from the top, letting water seep through to the bottom. Keep plants out of water for brief periods of time. Keep water away from the cactus’ body since it can cause decay.
5. Look for vermin. Check your leaves every month for mealy bugs and aphids. If a plant is infected, remove it from the vicinity of other plants and spritz it with a solution of 3 parts rubbing alcohol to 1 part water.
How can I prevent the freezing of my cactus?
Cover your cactus’ developing tips with styrofoam cups. This will keep them from freezing. They won’t be harmed by it. The majority of cacti are currently inactive and not growing. This past summer’s growth was delicate and has to be protected.
To prevent it from being blown off by the wind and endangering your plants, tie on any frost protection you use. Large-bulb Christmas lights will also keep plants warm, especially those big specimens that could be challenging to cover.
Never use plastic on your plants directly! Plants will freeze as a result of this moisture trap.
In the winter, should cacti be covered?
The resilient cactus are easily able to live in locations with a lot of snow cover. Cacti can get burnt or frostbitten in locations with strong winds, sun, and little snow. As late in the growing season as feasible, carefully wrap the plants in burlap to prevent damage.
Cacti can withstand 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.
In the winter, should I move my cactus away from the window?
To ensure that you always have some of your favorite plants in view, he advises keeping in mind that you may rotate plants by moving them from window to window. Cacti and succulent growers in cold climates, as well as those in warm climates that occasionally experience cold snaps, should avoid placing their plants too close to windows.
Help your cactus adapt
Enabling your cactus’ natural adaption mechanisms is the first step in defending it against frost. Allow the cactus to gradually adjust to the cold weather as the temperature drops in the days before the first frost.
You can allow the cactus to enter its dormant stage, stop growing, and have less moisture in its cells by reducing the amount of water you provide it.
Shelter your cactus from cold air
One of the precautions you may take is to shield your outside cactus plants from the chilly air if the frost is not too severe. If you have a little plant that you can move, do so to a more protected location, such as behind a wall or away from strong winds.
Outdoor furniture is another option for cactus protection. Your cactus will benefit if you place a chair over it because it will trap some of the heat. If you have a smaller cactus, you can also turn plastic containers over the plant while leaving a little opening for air to enter from the bottom.
Cover the soil with stones or mulch
In some cases, when the temperature drops, the earth might lose its heat quickly. Covering the ground with things that can assist trap the heat is one technique to save your cactus.
Some darker stone varieties are excellent for trapping the soil’s heat. Depending on the environment, black lava rock or red and brown rocks can aid in keeping the soil warm.
Mulch can be used to cover the soil as an alternative to stones. Mulch will keep your cactus comfortable by retaining heat. You must be careful not to use too much mulch, though, since this might trap moisture and lead to rot in your cacti, which cannot tolerate excess moisture.
Move your cactus indoors
Bring your cactus indoors if you live somewhere that gets really chilly. There are, however, a few considerations to make before doing so. First off, it’s crucial to avoid shocking the cactus with a fast shift in temperature, humidity, or light since this could impair its ability to adapt naturally.
When bringing your cactus indoors, be sure to choose a location with enough sunlight or furnish your plant area with a cactus-specific grow light. In order for the cactus to absorb as much sunlight as it need, you must also make sure that no dust or other obstructions are covering its surface. Make sure to modify your room’s temperature and humidity so that they don’t fluctuate much from the weather outside.
Make a frost blanket
This is a quick and easy technique to insulate your cactus from the cold. Several techniques are available for achieving this. There are high-quality, specialized frost blankets that keep the heat in the air layer surrounding the cactus.
Burlap, plastic sheets, and other materials are also options. While burlap will allow airflow and frost cloth, particularly if it is white, will let sunshine through, if you are using a plastic sheet, make sure to leave area for air.
Making ensuring the blanket doesn’t touch the cactus in any way is a crucial consideration. Wherever the material touches the cactus, it will produce a drop in temperature and result in areas of frost damage because the heat in this manner comes from the layer of trapped air.
To support the blanket and prevent it from moving, use a chair or other sturdy object. If it’s very chilly where you are, you might need to wear several layers of clothing. Another choice is to put a tiny artificial light inside the blanket to raise the warmth even further, especially if you’re doing this inside.
Why are cups placed on cacti?
You can tell a responsible plant owner if you’ve ever seen columnar cacti sporting Styrofoam cups.
Although many plants don’t require covering to withstand the freezes Tucson does see, some do require a little additional assistance when the temperature drops to 32 degrees.
Covering or not covering. The general services manager at Tohono Chul, a botanical garden on the northwest side with 49 acres of desert landscaping, is Bryce Beamish. We asked him that question.
It’s simple for visitors, in particular newcomers, to be taken aback by how chilly it may get at night, according to Beamish. “Additionally, there is no humidity, so it’s not simply chilly. Anything that is not acclimated to this environment can suffer greatly during the cold, dry evenings. Also, we always advise people to plant as many locally indigenous species as they can.”
Know what you have
Knowing a plant’s identity is necessary before deciding whether to cover it. Knowing the plants you have will let you conduct additional study, according to Beamish.
For instance, native plants typically don’t require covering
Choosing indigenous plants has another another advantage.
You could see sheets covering saguaros or prickly pear trees in paper bags, but Beamish explains that this is just a common mistake. “Our natural plants are often adapted to survive our winters,” I usually tell them.
What to cover and how
Columnar cactus are among the most popular plants used in Tucson landscaping, according to Beamish, and they require extra care during the winter.
The most delicate portion of the cacti is where new growth enters directly at the top, he explains, which is why we place Styrofoam containers on them.
Get inventive if you run out of Styrofoam cups. Just wear a Santa hat. In reality, all you’re searching for is insulation.
When temperatures drop, citrus trees also need some extra warmth. Trees with more experience can withstand a frost better than younger plants. The simplest remedy? Bring your tree inside if it’s in a pot. If not, you have a few choices.
Giving the trunk warmth is how to keep it from freezing, according to Beamish. “Wrapping the tree’s real trunk is one of the simplest ways to do that.”
You can use paper or cloth, but not plastic—this is where extra bed sheets come in handy. Plastic will freeze if it gets wet, which is why.
The most crucial step, according to him, is getting the wrap to touch the ground since that is where the heat will come from. You need to transfer heat from there into the wrap in order for it to adhere to the tree trunk, because there is where the heat is.
Should cacti be sheltered against frost?
You might be surprised to learn that cacti are among the best-known warm-weather plants and can suffer freezing damage. However, even in Arizona’s hot and dry summers, wintertime lows of 32 degrees Fahrenheit (0 degrees Celsius) are not uncommon. Cactus may suffer freezing damage as a result of this.

In the winter, how frequently should I water my cactus?
Cactus plants require relatively little upkeep. They may thrive without much care and simply need occasional watering. They don’t need as much maintenance as other plants do.
Cactus plants often need to be watered once every one to two weeks. To avoid overwatering, which can lead to root rot, if there is a lot of rain in your location (more than an inch per week), you should water once every three to four weeks.
When the soil has dried out but before it becomes too hot outside, is the ideal time to water your cactus.
You should aim to provide the plant with enough water while avoiding dehydration when the weather is too hot for their roots because the heat from the sun will soon dry out the plant.
Depending on how frequently they go through cycles of soaking and drying out during warmer weather conditions, you should water your cactus using an automated drip system once or twice a week.
Regular watering of your cactus promotes blooming in addition to aiding in growth.
How Often Do You Water a Cactus in Summer
During the summer, most people water their cacti once a week, but this can vary.
Give your cactus some extra watering if your soil is dry for a few days and it doesn’t rain to make sure they stay hydrated and healthy.
Summertime temperatures are typically warmer, so your cactus will require more water than it would in the dead of winter.
If you live somewhere where summer days can reach above 100 degrees Fahrenheit, you might want to think about watering your plants twice a week if they are indoors or close to a window due of the added heat.
During the summer, you should strive to water cactus outdoors one or two times per week. Don’t worry about watering them the following day if it rains.
Your cactus will need less water than those grown somewhere warmer with constant summer heat if you reside in a cooler region with temperature swings of hot and cold temperatures or icy winters.
Keep a watch on their soil to make sure that when it gets below 50 degrees Fahrenheit, all areas have access to moisture.
How Often Do You Water a Cactus in Winter
Your cactus won’t need as much water in the winter while it is dormant and growing more slowly because the cold weather slows down their metabolism.
During the winter, you should typically water your cactus once every two weeks. Before rehydrating the soil, make sure it is absolutely dry, and then allow it to completely drain.
Because cacti have slower metabolisms throughout the winter when they are dormant, you should avoid overwatering your cactus. The roots will rot if you overwater them, which will harm your plant.
On the other hand, if you wait too long between waterings in the winter when they’re slower growing and don’t need as much water, the likelihood that they’ll perish from the cold is enhanced.
Therefore, throughout the winter months, err on the side of caution and water your cactus about once every two weeks.
Take care not to water at all during dormant times if you live in an area with extremely cold winters (below USDA Zone #11) as this could encourage growth that isn’t appropriate for your location.
Watering Requirements for Cacti That Are Not Dormant
If your cacti are not dormant and you reside in a region where winters are moderate and temperatures don’t drop below freezing, you might want to water them more frequently.
Some cactus species do not require a period of dormancy throughout the winter. These cacti need to be watered more frequently than the typical cactus.
You should water your plant once per week or every two weeks throughout this time of year.
During these months, make sure the soil is totally dry before watering it once more, and then allow it to completely drain.
Fast-draining potting soil will also aid in avoiding overwatering, which can result in root rot during the winter when temperatures are lower.
How Often Should You Water an Indoor Cactus
Cactus cultivation in containers differs from outdoor cultivation. Other considerations also need to be taken into account.
The size of your container and its drainage holes should be your first concern.
If they’re too small, you’ll have difficulties with overwatering; if they’re too huge, the plants will dry out before you water them again.
Pick up your pot and feel how weighty it is to get the best idea of the right size. The more substantial the better, as this indicates that you have provided sufficient potting mix for good drainage.
The type of cactus plant, the humidity levels in your house or workplace, the seasons (autumn and winter tend to be drier than spring and summer), etc. will all have an impact on how often you need water indoor cacti in pots.
If every one of these factors stays the same throughout the year, then once every one to two weeks ought to be sufficient.
Just be careful not to water them excessively! After all, cacti are desert plants. The fastest way to destroy an indoor cactus garden is with too much water!
Finally, think about filling the bottom of the container with grit or gravel.
You won’t have to worry as much about overwatering them because this will improve drainage and promote aeration.
