You may love stunningly beautiful rose succulents and low-maintenance ground covering succulents because of their aesthetic appeal and neglect-resistant nature. However, not all succulents are alike. While shade-loving succulents often find their way indoors, some find their sweet spot outdoors.
Most varieties of succulents are said to be neglect-resistant and sensitive to overwatering and overexposure to direct sunlight. They may be easy to grow, but you have to ensure that you give them what they need. Otherwise, they might etiolate, suffer from sunburn, rot, get infested with pests, or die. Aside from that, different succulent varieties have different needs, so you need to identify the unique conditions of your chosen succulent. This is key to their survival.
If you live in areas where sunlight is scarce and cold weather is the default climate, yet you still have that nagging desire to grow succulents, you might want to consider raising cold hardy succulents instead.

What Are Cold Hardy Succulents
When you talk about cold hardy succulents, it refers to the cold temperature-tolerant succulent plants that grow in areas with freezing and below freezing temperatures. Just like their soft, succulent counterparts, they also store water in their leaves and stems. This is the reason why they need less watering compared to traditional flowers and plants.
Surprisingly, there are cold hardy succulents that thrive even in areas with below 0°F temperature. These succulents are known to grow in USDA zones of 4 to 5 hardiness. In addition, some succulents flourish even though they live through winters with -29 Celsius temperature.
Benefits of Cold Hardy Succulents
Remove Toxins From the Air
There are many benefits to growing succulents. Generally, succulents remove toxins from your breathing air. Haworthia succulents are grown indoors, so they add aesthetic appeal to your home. But that’s not all there is to succulents.
Tolerant to Frost
The cold hardy varieties are named such for a good reason – they are extremely tolerant of harsh environmental conditions. The fact that they grow even in areas with cold temperatures is also another benefit. This means that you can leave them outdoors and not worry whether they survive or not. For as long as you give them enough sunlight and you water them sparingly, they will survive.
These plants are also drought and neglect-resistant, so even if you don’t have time to take care of them, they will survive. This is ideal for homeowners in plant growers who could not be hands-on in taking care of their plants. They don’t have to maintain and cultivate them now and then. As long as you provide these plants with the right environment and growth conditions, they will surely grow.
How Do Cold Hardy Succulents Work
Some hardy succulent plants need a lot of light, so you must grow them outdoors to expose them to partial sun. Make sure that they’re under the shade where the temperature does not go above 85°F. However, if you want to grow them indoors, you need to keep them in an area to access enough light. Ideally, place them next to a sunny window sill.
Like other succulent varieties, hard and cold varieties also grow best in gritty, well-draining soil. So, ensure that you use a succulent or cactus potting mix to ensure excess water doesn’t get absorbed by the soil.
If you want the roots of your cold and the hardy succulent plants to develop healthily, you need to soak them in water and then let them fully dry. Take note that young succulent plants will need more watering to establish their roots. However, all hardy succulents prefer less watering during winter. If you plant them in the container, make sure you use a pot with a drainage hole.
Most hardy succulents can tolerate deep freezing temperature that’s down to -20°F. Some succulents, especially those belonging to zone 4 hardiness, can tolerate up to -30°F temperature. Thus, snow can protect your hardy succulents from too much winter exposure. However, if you’re growing cold hardy succulents in snow-free regions, you need to place your potted succulents under shelter and cover them to prevent water from dropping their roots.
There’s no need to propagate these varieties. However, there are specific instructions regarding transplanting and multiplying every succulent type.
