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.
Succulents go dormant in what month?
Succulents have historically been categorized as either “Winter Dormant” or “Summer Dormant.” Let’s explore the implications for succulents.
Winter dormancy in succulents is replaced by active growth in the spring, summer, and fall. However, they will experience a brief period of dormancy and slow down their growth during the hottest days of summer (July/August in the US).
These plants don’t like the excessive heat and will shut down to survive, despite the fact that they tend to prefer warmer temperatures than some of their other succulent relatives.
But once the temperature drops below 40F, you’ll notice that growth rapidly slows down. As was already indicated, minimize the watering of these plants when they are dormant to prevent them from rotting.
How do I recognize a dormant succulent?
I bring up dormancy as a crucial aspect of succulents since it would be dreadful to just discard a plant because it lost its leaves or to try to withhold or, opposite, offer too much water in the hopes that it may “revive” the plant. We can better understand the demands of our plants if we are aware of the seasonal dormancy of succulents. Knowing when succulents will fall dormant might be challenging, but not impossible, when we purchase them without even knowing their names or genera. Simply keep an eye out for the signs!
One of the first signs of a succulent going into hibernation is that it entirely stops growing. If they have fleshy leaves, as my Senecio does, they will simply turn yellow or brown and fall off the sides of the plant stem or hang limply. Some kinds will see rosettes that shrink. Additionally, you’ll observe that Mesembs from the Titanopsis genus develop a papery covering.
A well-known cactus gardener once advised me to water succulents sparingly in the winter, only once every two weeks, and to stop watering cacti entirely from November to March. This is a sound general rule of thumb, but it requires a bit more nuance since, as we now know, different succulents go dormant at various periods of the year and require various environmental conditions. You might need to water them more regularly during the dormant season if you live in a hotter climate because transpiration will still be taking place during that time.
A plant should never be repotted while it is “sleeping,” as well.
How would you feel, for example, if you were abruptly awakened from a sound sleep and told to relocate? I assume not that much. The same is true of plants, especially succulents. You should be safe to make some planter alterations at the first sign of growth because they would prefer to be replanted when they are growing.
This handy chart, which I put up using information from a variety of sources, such as Highland Succulents, Succulents.us, and a variety of books, will assist you in determining your succulents’ seasonal dormancy if you are familiar with their genera:
All succulents hibernate throughout the winter, right?
Succulents don’t grow at the same rate all year long like most other plants do. Most transition between a dormant and an active period.
Some succulents go into hibernation in the winter, while others do so in the summer, during which time they develop less.
Dormancy in succulents is brought on by a few factors in their natural environment. Succulents are sensitive to changes in temperature and light exposure.
They elect to operate in “energy-efficient” mode after realizing that it will not provide the ingredients they require for active growth.
Succulents don’t need fertilizer or much water when they go dormant. It will still require sunlight to maintain its compact form and quick-draining soil to keep it dry.
Succulents’ indoor and outdoor dormancy periods are affected by a few different factors, which are described here:
Prepare succulents for indoor living
Spray your succulents with a surface pesticide before bringing them inside. To ensure that your succulents are pest-free, this preparation should take place at least 3 weeks before their indoor adaption. By doing this, you can stop insects and other pests from spreading to your indoor plants.
After clearing the garbage, weeds, and leaves, look for any indications of an infestation. Change the soil if you notice flies gathering around the succulents. When you bring them inside your home, they will quickly spread to the neighboring plants if you don’t.
Make sure your succulent is in a pot with a drainage hole and well-draining soil. Because outdoor environments frequently have greater ventilation, a proper soil mixture is essential for indoor growing of succulents. Succulents need sufficient air circulation to sustain healthy roots. To improve drainage, you can also add pumice or perlite to the potting medium.
In addition to these actions, gradually cut back on the watering of your succulents. The plants will go into dormancy and be able to endure the harsh winter with the help of less water and a lower temperature.
Bring the succulents inside 
Stop watering your indoor succulents and allow the soil to dry up. Water them lightly during the winter, just enough to prevent dehydration. Ensure that the temperature is consistently between 50 and 60 degrees Fahrenheit.
Providing enough light for succulents in the winter is another factor to take into account for indoor adaption. If your succulents have been kept outdoors for a while, they may have grown accustomed to regular exposure to intense light. It’s better to replicate their growing environment indoors. A sunny windowsill can provide 6–8 hours of bright light in warm zones 9–11, but in places with little sunlight, you might want to consider obtaining a succulent growth lamp.
Fluorescent lighting will promote healthy, stress-free plant growth, especially for non-dormant succulents.
Succulents under grow lights dormancy?
I don’t have much experience growing succulents in cold temperatures and dark winters because I live in sunny Southern California. I’m fortunate enough to be able to leave my plants outside all year long without significant frost or low light harm. I am aware that many of you reside all over the world and are unsure of what to do with your plants now that you have brought them indoors for the winter. Perhaps despite the fact that you have your plants on window sills, they are still growing languidly, or perhaps the winters in your area are completely dark. Look nowhere else! I’m very happy to have indoor plant growing specialist Ben Thorton here with us today to share his knowledge about using grow lights to support the growth of your lovely garden regardless of the lighting situation!
Succulents have recently risen to the top of the list of preferred indoor plants because of how attractive they are, how they enhance the atmosphere of your home, and how little maintenance and water they need compared to other indoor plants. Many people are reluctant to grow succulents in regions with short summers because they are warm-weather and sun-loving plants. You might be shocked to learn that even if you live in a climate with distinct seasons and chilly, gloomy winter months, you can still grow succulents all year round. Once the weather becomes cooler, just move the succulents inside and provide the artificial lighting they require. Here is a simple tutorial on growing succulents indoors and under artificial lights if you are unsure about using grow lights or worried that you might harm your plants by using them.
Artificial lighting can be categorized as either lighting used in addition to natural lighting or lighting utilized to perfectly mimic sunlight in situations where none actually exists. Since vitamin D, one of the most important vitamins in the human body, is obtained from sunlight, artificial light cannot replace it for humans. In contrast to other living things, plants just require the light itself from the sun. Photosynthesis is a process that takes place when plants are exposed to light and provides them with the energy they require to grow. Succulents can be grown indoors under artificial light just as well as outdoors in natural sunshine, provided that the right amount of light is provided. To successfully grow your succulents in your house, you will need to select the best lights and understand a few basic lighting techniques.
There are a few considerations to keep in mind when selecting artificial lighting for an indoor garden. And they are as follows:
How strong and bright is the light produced by the grow lights?
The brightness of the light produced by grow lights is the most important factor to consider because it will affect how much light the plants receive and how well they can grow. You need lights for succulents that produce at least 2,000 lumens per square foot of illumination. 10,000 lumens per square foot are produced by noontime direct sunlight, but if you run 2,000 or more lumen lamps for 14 or more hours a day, the plants will receive almost the same amount of light as they would in the height of summer.
What is the light’s wattage?
Another item to consider is the wattage of the grow lights you buy, as this will have an impact on your electricity bill. You pay more for electricity the more watts a light uses, therefore you don’t want to choose a light that is brilliant but uses a lot of watts because that will be very expensive. To get the best of both worlds—bright light for your plants and minimal electricity consumption for you—look for lights that are marked as energy efficient. These lights will likely have a high lumen count and low wattage, giving you the best of both worlds.
What color temperature range does the light produced by grow lights fall into?
Because succulents love the sun and prefer bright light to shadow, they also need a particular light with regard to the color temperature of the light. The visible color that the grow lights emit is essentially their color temperature. Kelvins are used to measure this. To provide the light that plants require to thrive, light must fall within a certain range of color temperatures. Starting at roughly 5,000 Kelvins, the ideal color temperature for succulents will provide your succulents cool, full-spectrum light that closely resembles sunlight.
How much heat is emitted by the light?
Finally, it is crucial to understand how much heat the grow lights emit. If they produce a lot of heat, you can experience a problem with the temperature in the space where you grow your succulents, which would require you to invest extra money in a reliable ventilation or cooling system. Additionally, if lights produce a lot of heat, you will need to situate your plants farther away from the lights in order to prevent them from burning them. Your plants may not receive enough light as a result. Some typical grow lights are known to emit a lot of heat, while others remain cool to the touch even after being on for 24 hours. Make sure a grow light doesn’t produce too much heat before you buy one.
I would advise you to purchase T5 grow lights since they have all the qualities of a good grow light and I have experience working with many various types of grow lights. Their diameter is 5 eights of an inch. T5 grow lights are available in a variety of configurations, including two different lengths (2 ft and 4 ft bulbs), numerous different bulb counts (from 1 to 12 bulbs in one fixture), various efficiency types (Normal Output (NO), High Output (HO), and Very High Output (VHO), and various color temperature varieties (from only 2,900 Kelvins up to 10,000 Kelvins). I typically use high output (HO) bulbs because a 2 foot HO T5 bulb uses just 24 watts and produces 2,000 lumens, compared to a 4 foot long high output (HO) T5 bulb that uses 54 watts and produces 5,000 lumens. You obtain incredibly effective light that is ideal for succulents if you mix one or the other length bulbs in a group of two or more bulbs and choose bulbs that are in the color temperature of 6,500 Kelvins.
Although choosing the correct artificial light is an important aspect of effectively growing your plants in an indoor garden, there are a few other factors you should be aware of in order to do even better.
Be aware of the height at which you should hang your plant canopy’ grow lights.
Knowing how high to hang your grow lights is essential since it affects how much light the plants receive. You must hang grow lights so that they may provide the maximum amount of light to the plants without overheating them by radiating heat, regardless of whether you select T5 fixtures or select other grow lights. In order to reduce the risk of your grow lights burning and harming your plants, I would first advise placing any grow light at least 6 to 8 inches away from the tops of your succulents. You can later move your lighting fixtures closer to the succulents if you discover that they don’t emit heat and are cold to the touch (like T5 grow lights).
Determine the light cycle
Because there won’t be a sun to determine when plants receive light, you must determine the plants’ light cycle while growing plants indoors under grow lights. Knowing your light cycles will help you grow your succulents more quickly. Indoor gardens use light cycles to replicate day and night circumstances. Succulents will also develop more quickly if you give them more light, which is a common rule of thumb for growing any plants under lights. If you’re overwintering the plants, I’d recommend starting with a 20/4 light cycle for the succulents. This means leaving the lights on for 20 hours a day, turning them off for 4 hours, and then gradually extending the darkness time until the light cycle is 16/8 (light/dark). Succulents require knowledge of the winter solstice so they can begin their dormant period. If you use grow lights all year for your succulents, you may set the light cycle to 24/0 or 20/4 in the summer to help them develop swiftly and flourish.
Learn how frequently to water your succulents.
Finally, it should be noted that watering is equally crucial because both inadequate and excessive watering might harm your plants. Even if you’re using grow lights to simulate summer, you still need to water the succulents during the summer by watering them once the soil is dry. Even if succulents are cultivated indoors, things change over the winter. Succulents use substantially less water while they are dormant throughout the winter or an imitation of winter since they are either growing very slowly or not at all. So, how frequently should you water succulents in the winter? In general, I’d advise watering them every two weeks, but if the room is hot, you’ll need to water them more frequently because the heat will cause them to dry out more quickly. Looking at the soil in which succulents are growing will tell you how frequently they need watering during the winter. Allow the soil to dry up completely before giving succulents approximately a week to absorb the water before you water them again to prevent overwatering.
