If you’ve been growing succulents for a while, you might have experienced this panic: “My Echeveria stopped growing. Is it dying?” Or, “I watered my Lithops exactly like I did in July, and now it’s mush.”
Relax. You didn’t kill it. Most likely, your plant just clocked out for its seasonal vacation.
Just like bears hibernate and trees lose their leaves, succulents enter a dormancy period. Understanding this cycle is the single most important factor between thriving plants and a pot of rot.
Here is your complete guide to the succulent “off-season.”
Summer vs. Winter Dormancy (Yes, there are two types)
Most people think succulents grow in the summer and sleep in the winter. That is only half true.
Actually, succulents break into two distinct groups:
- Summer Growers (Winter Dormant)
These guys love the scorching July heat. They sleep when the days get short and cold.
Examples: Agave, Aloe, Haworthia, and most Cacti (except Christmas cactus).
- Winter Growers (Summer Dormant)
These plants hate the blazing summer sun. They wake up when temperatures drop in October and sleep through the heatwave.
Examples: Aeonium, Aloe (some varieties), and the Aizoaceae family (Lithops – Living Stones, and Pleiospilos – Split Rocks).
Quick cheat sheet: If it looks like a rose (Sempervivum/Echeveria), it usually grows in summer. If it looks like a brain or a rock (Lithops), it grows in winter.
The 3 Tell-Tale Signs Your Succulent is Sleeping
Dormancy isn’t usually obvious. Your plant won’t snore. Look for these subtle changes:
The Color Fades: A vibrant purple Echeveria turns a dull, ghostly green.
Closed for Business: New leaves stop forming. The center of the rosette tightens up or simply halts growth entirely.
The “Thirsty” Lie: The outer leaves may shrivel or droop slightly. Do not mistake this for dehydration. This is the plant eating its own stored energy.
The Golden Rule of Dormancy: Watering
Water is the #1 killer of dormant succulents. A sleeping plant has closed its pores (stomata). If you pour water into the soil, the roots cannot drink it. Instead, the water sits there, bacteria grows, and you get root rot.
The Protocol:
Growing Season: Water thoroughly when the soil is 100% dry (every 7–10 days).
Dormant Season: Water only when the plant looks desperate (every 4–6 weeks, or even less). For Lithops, water zero times during summer dormancy.
Pro tip: When in doubt, wait a week. A succulent can survive 6 months without water. It cannot survive 6 days of wet feet.
Location, Location, Location
Summer Dormant (Aeoniums, Lithops): Move them to bright, indirect light. No harsh afternoon sun (2:00 PM to 5:00 PM). Think “bright shade.” A east or north-facing window is perfect.
Winter Dormant (Echeveria, Cacti): They need cool temperatures (5–15°C / 40–60°F) and very dry soil. If your garage or unheated guest room stays cold but frost-free, put them there.
Common Mistakes (Even experienced growers make these)
Mistake #1: “It’s 90°F outside, so I must water.”
Wrong. If it is a Winter Grower (Aeonium), it is trying to sleep. Hot soil + wet roots = steamed vegetable.
Mistake #2: “My plant looks wrinkled. It needs a drink.”
Check the soil first. If the soil is wet and the plant is wrinkled, you have root rot. Stop watering immediately. If the soil is dry and it’s winter, give it a tiny sip, not a flood.
Mistake #3: Fertilizing during dormancy.
Never. Fertilizer is a growth hormone. Trying to force a sleeping plant to grow is like waking a teenager at 3:00 AM. You will both be unhappy. Stop all fertilizer from November to February (for winter dormant) and June to August (for summer dormant).
One Exception to Every Rule
Your home is not nature. If you keep your house at 72°F (22°C) year-round with grow lights on 14 hours a day, your succulents may never fully go dormant. In this case, they will grow slowly all year. Adjust your watering to match the plant’s speed. If it isn’t growing fast, don’t water fast.
The Final Takeaway
Observe your plants. Keep a calendar. Most succulents are killed by kindness (too much water), not neglect.
If you learn nothing else, remember this: Dry and cool for winter growers. Shaded and drier for summer growers.
When your friends ask why their cactus turned to soup next July, you can smile and say, “You watered it while it was sleeping.”
