Jade plants (Crassula ovata) are those easy-to-care-for succulents with plump, shiny leaves and a charming, tree-like shape. They’re a favorite for houseplant lovers, thanks to their hardiness and beautiful look. But when the temperature drops, many of us start to wonder: how cold can jade plants really tolerate?
If you’re asking this question, you’re in the right place. In this article, I’ll walk you through everything you need to know about jade plant cold tolerance. We’ll talk about the temperatures they’re happiest in, how to spot cold stress, and the best ways to protect your plant when winter hits.
As someone passionate about helping others grow healthy plants, I’m Tahsin All Habib, the founder of TerrariumMaster.com, and I’m excited to share what I’ve learned over the years to keep your jade plant thriving.

What’s the Ideal Temperature for Jade Plants?
Jade plants love warm, dry conditions, which is why they thrive in indoor environments that mimic their native South African habitat. To keep them happy and healthy, you’ll want to stick to a temperature range that suits them best.
- Daytime temperature: Around 65°F to 75°F (18°C to 24°C)
- Nighttime temperature: No lower than 50°F (10°C)
If the temperature regularly dips below this range, your jade plant might start feeling stressed, which can lead to problems down the road.
How Cold Can Jade Plants Actually Handle?
Jade plants can tolerate a brief dip in temperature, but they’re not fans of the cold. In fact, temperatures around 40°F (4°C) are about as low as they can go without starting to show signs of stress. If the temperature stays below 45°F (7°C) for too long, you might see leaf drop, discoloration, and even permanent damage to the plant.
Here’s the important takeaway: Jade plants are not frost-tolerant. If the temperature drops below 32°F (0°C)—which means it’s freezing—your plant is at serious risk. The water inside its leaves will freeze, causing them to break down. This could lead to frostbite, which is often fatal for jade plants.
What Happens to Jade Plants When It Gets Too Cold?
If your jade plant gets too chilly, a few things will start to happen:
- Leaf discoloration: You might notice that the leaves start turning purple, brown, or black. This is one of the first signs that cold stress is setting in.
- Mushy or transparent leaves: When the water inside the leaves freezes, it expands and damages the cell walls. The result? Soft, mushy, or even transparent leaves.
- Leaf drop: Jade plants may shed their leaves as a survival tactic when they’re under stress. If your plant starts dropping leaves, it’s a sign it’s struggling with the cold.
- Stem damage: If you notice the stems turning brown and mushy, that’s a sure sign that the cold has taken a toll. Unfortunately, once the stems are damaged this badly, they usually won’t recover.
Can Jade Plants Survive Frost?
I’m afraid not. Jade plants are very sensitive to frost. Because their leaves and stems store a lot of water, they’re especially vulnerable when temperatures drop below freezing. Even one night of frost can kill an outdoor jade plant overnight.
If you live in USDA Hardiness Zones 10 or 11—where the weather rarely goes below freezing—your jade plant can live happily outside year-round. But if you’re in any other zone, you’ll want to treat your jade as an indoor plant. Bring it inside before the cold sets in.
How to Protect Your Jade Plant from Cold
Whether your jade plant lives inside, on a patio, or in a greenhouse, taking a few simple steps to protect it from the cold is key. Here’s what you can do:
- Move It Inside Before First Frost:
Once nighttime temperatures fall below 50°F (10°C), bring your jade plant inside. Place it near a bright window but away from any cold drafts. Cold air from windows or doors can stress your plant out. - Avoid Sudden Temperature Shifts:
Jade plants don’t like abrupt changes. If you’re moving your plant indoors, try gradually acclimating it by bringing it inside for a few hours each day before making the full switch. - Keep It Away from Cold Windows:
Even indoors, your jade plant can suffer if it’s placed right next to a cold window. Move it a little farther from the window or use thermal curtains at night to keep the chill out. - Cut Back on Watering:
In the winter, jade plants slow down their metabolism, meaning they don’t need as much water. Overwatering a cold jade plant can lead to root rot, so only water when the top 2 inches of soil feel dry to the touch. - Use a Grow Light:
If you don’t get a lot of natural light during the winter, consider using a grow light. Jade plants need about 4-6 hours of indirect light each day, and a grow light can help prevent them from becoming leggy or dropping leaves.
What to Do if Your Jade Plant Gets Too Cold
If you didn’t act in time and your jade plant has already been exposed to cold temperatures, don’t panic. Here’s how to try saving it:
- Move It to a Warm Spot:
First, get your plant into a warm, well-lit area (between 60°F and 70°F ideally). - Assess the Damage:
Take a close look at your plant. Are the leaves soft and mushy? Are they turning black or transparent? If so, these parts won’t recover. - Prune the Damaged Parts:
Use clean, sharp scissors to remove any leaves or stems that are too far gone. If the main stem is damaged, consider taking healthy cuttings from the plant to propagate. - Hold Off on Watering:
After you’ve pruned the damaged areas, let the plant rest. Don’t water it until the soil has dried out completely.
Do Jade Plants Go Dormant in Winter?
Yes, they do! When the temperature drops and light levels decrease, jade plants enter a semi-dormant state. During this time:
- Growth slows down.
- They use less water.
- Fertilizing should be stopped.
This is a natural process that helps the plant conserve energy and survive the colder months. Come spring, they’ll be ready to start growing again.
Cold-Tolerant Alternatives to Jade Plants
If you live in an area with consistently cold winters, you might be looking for a succulent that can handle the chill a bit better. While no plants in the jade family are truly frost-tolerant, there are a few succulents that can handle cold better than jade:
- Sedum varieties (many are frost-tolerant)
- Sempervivum (Hens and Chicks) – can survive temperatures as low as -30°F!
But if you’re really set on having a jade plant, indoor growing is your best bet.
Final Thoughts: Keep Your Jade Plant Safe from the Cold!
Jade plants are hardy, beautiful succulents, but they do have their limits when it comes to cold weather. To recap:
- Minimum safe temperature: 40°F (for short exposure)
- Ideal temperature range: 65°F–75°F
- Frost = fatal: Anything below 32°F is a danger zone.
By following these simple tips, you can protect your jade plant from the cold and keep it thriving all year long.
