Ah, succulents! Those charming, architectural plants that bring a touch of the desert to our homes. Their plump leaves and fascinating shapes are undeniably appealing, but for many plant parents, a nagging question persists: watering succulents, how often?
It’s a question that can lead to overwatering woes or underwatering wilt, both detrimental to these resilient yet sensitive beauties. The truth is, there’s no single, universal answer. Unlike their thirsty leafy cousins, succulents have evolved to store water, making them incredibly drought-tolerant. This unique adaptation means they thrive on neglect rather than constant attention, but ‘neglect’ doesn’t mean ‘forgetting’.
Understanding your succulent’s needs is key to unlocking its full potential and keeping it vibrant for years to come. Let’s demystify the art of succulent watering and ensure your spiky friends stay happy and healthy.
The Golden Rule: When in Doubt, Wait It Out
This is perhaps the most crucial piece of advice for any succulent owner. Succulents are far more forgiving of underwatering than overwatering. Excess moisture is the number one killer of these plants, leading to root rot, fungal diseases, and a general decline in health. Overwatering suffocates the roots, preventing them from accessing oxygen and eventually causing them to decay. When this happens, the plant can’t absorb water or nutrients, leading to yellowing, mushy leaves, and a sad, limp plant.
Conversely, underwatered succulents will show signs of thirst. Their leaves might start to shrivel, wrinkle, or feel less plump. This is the plant’s way of conserving water. Fortunately, most succulents can recover remarkably well from a period of drought, often bouncing back to their former glory with just a good soak.
Factors Influencing Watering Frequency
So, if there’s no set schedule, what dictates how often you should water your succulents? Several environmental and plant-specific factors come into play:
1. Potting Medium and Drainage
The soil your succulent is planted in is paramount. Standard potting soil retains too much moisture for most succulents. They need a well-draining mix that allows water to pass through quickly. A good succulent or cactus mix typically contains ingredients like perlite, pumice, coarse sand, and grit, which improve aeration and drainage. If your pot doesn’t have drainage holes, it’s a recipe for disaster, regardless of how often you water. Always use pots with drainage holes!
How to check your soil: The best way to know if your succulent needs water is to feel the soil. Stick your finger about an inch or two into the soil. If it feels dry at that depth, it’s likely time to water. If you feel any moisture, hold off.
2. Environmental Conditions
Temperature: Succulents generally prefer warmer temperatures. In hot, dry weather, they will use water more quickly and may need watering more frequently. In cooler temperatures, their metabolism slows down, and they require less water.
Humidity: High humidity levels mean the soil will take longer to dry out. In humid environments, you’ll need to water less often. Conversely, in very dry climates, the soil will dry out faster. (See Also: self-watering pots how to use)
Light Exposure: Succulents that receive more sunlight will generally dry out faster than those in lower light conditions. Plants actively photosynthesizing and growing will use more water.
3. Seasonality
Succulents have growth cycles, and their water needs change accordingly. Most succulents are considered ‘summer growers’ or ‘winter growers’.
- Summer Growers: These succulents are most active during the warmer months. They will require more frequent watering during spring and summer and significantly less during fall and winter.
- Winter Growers: These succulents are active during the cooler months. They will need regular watering in fall and winter and should be kept mostly dry during the hot summer months.
It’s important to identify whether your succulent is a summer or winter grower to adjust your watering schedule accordingly. Many common succulents like Echeverias, Sedums, and Sempervivums are summer growers.
4. Pot Size and Material
Pot Size: Smaller pots tend to dry out faster than larger pots because there is less soil to hold moisture. If your succulent is in a tiny pot, you might find yourself watering more often.
Pot Material: Terracotta pots are porous and allow water to evaporate from the sides, meaning the soil dries out much faster than in plastic or glazed ceramic pots. If you’re using a terracotta pot, you’ll likely need to water more frequently than if you’re using a plastic pot.
5. Succulent Type and Maturity
Different types of succulents have slightly different water needs. For example, cacti, which are a type of succulent, are incredibly drought-tolerant and can go for very long periods without water. Leafy succulents, like Echeverias, might show signs of thirst a bit sooner.
Mature succulents tend to be more drought-tolerant than young, newly propagated ones. Young plants are still establishing their root systems and may benefit from slightly more consistent moisture, though still allowing the soil to dry out between waterings.
How to Water Your Succulents Correctly
Once you’ve assessed the factors above and determined that your succulent is ready for a drink, here’s how to do it right:
The Soak and Dry Method
This is the most recommended method for watering succulents. It mimics natural rainfall, where the soil gets thoroughly saturated and then has time to dry out completely. (See Also: how to use a self watering pot)
- Water Thoroughly: When you water, water until you see water draining from the drainage holes at the bottom of the pot. This ensures that the entire root ball is moistened.
- Allow to Drain: Let the pot drain completely. Do not let the pot sit in a saucer full of water, as this will lead to root rot. Empty any excess water from the saucer after about 15-30 minutes.
- Wait for Soil to Dry: Crucially, allow the soil to dry out completely before watering again. This could take anywhere from a week to several weeks, depending on the factors we’ve discussed.
Signs Your Succulent Needs Water
Keep an eye out for these tell-tale signs:
- Wrinkled or Shriveled Leaves: This is the most common indicator. The leaves will lose their plumpness and start to look deflated.
- Soft or Mushy Leaves: While this can also indicate overwatering, sometimes very dehydrated leaves can become soft and limp. The key is to differentiate between a healthy plumpness and a deflated, wrinkled appearance.
- Curling Leaves: Some succulents will curl their leaves inwards when they are thirsty.
- Soil Pulling Away from Pot Edges: As the soil dries out, it can shrink slightly, creating a gap between the soil and the edge of the pot.
Signs Your Succulent Is Overwatered
Recognizing these signs is just as important:
- Yellowing Leaves: Lower leaves often turn yellow and may become translucent.
- Mushy or Translucent Leaves: Leaves feel soft and waterlogged, often splitting or dropping easily.
- Rotting Base: The base of the plant may turn brown or black and feel soft and mushy. This is root rot setting in.
- Edema: Small blisters or bumps on the leaves, caused by the plant taking up too much water.
- Mold or Fungus: Visible mold on the soil surface or the plant itself.
Common Watering Mistakes to Avoid
Let’s address some common pitfalls that succulent owners often encounter:
1. Watering on a Schedule
As we’ve emphasized, succulents don’t thrive on a rigid schedule. Watering every Saturday, for instance, might be too much in winter and not enough in a heatwave. Always check the soil moisture before watering.
2. Misting
Misting succulents is generally not recommended. It only moistens the surface of the soil, encouraging shallow root growth. More importantly, water droplets on the leaves can lead to fungal infections, especially in humid conditions or if the plant doesn’t have good airflow. Succulents prefer a deep watering that reaches the roots.
3. Watering From the Top and Getting Leaves Wet
While the soak and dry method is best, if you are watering from the top, try to direct the water to the soil, not the plant’s leaves. Excess water trapped in the rosettes of some succulents can lead to rot.
4. Using the Wrong Soil
As mentioned, standard potting soil is a no-go. Invest in a good quality succulent or cactus mix, or create your own by amending regular potting soil with perlite or pumice.
5. Forgetting About Drainage
We can’t stress this enough: drainage holes are non-negotiable. If your decorative pot doesn’t have them, use it as a cachepot for a nursery pot that *does* have drainage holes.
Watering Succulents in Different Scenarios
Indoor vs. Outdoor Succulents
Indoor Succulents: These are often in more controlled environments. Light might be less intense, and airflow can be reduced. They may need watering less frequently than outdoor succulents, especially in cooler months. Pay close attention to humidity levels in your home. (See Also: how to stop watering eyes)
Outdoor Succulents: These plants are exposed to the elements. Rain can water them, but you need to ensure they don’t get waterlogged. In hot, dry spells, they might need more frequent watering, but always check the soil first. Outdoor plants generally experience more drastic temperature fluctuations, which also affect drying times.
Watering Cacti
Cacti are succulents, but they are exceptionally drought-tolerant. They prefer their soil to dry out completely and stay dry for extended periods. During their active growing season (usually spring and summer), water thoroughly only when the soil is bone dry. In winter, many cacti go dormant and require no water at all.
Watering Echeverias
Echeverias are popular for their beautiful rosette shapes. They prefer their soil to dry out completely between waterings. Water thoroughly when the soil is dry, and ensure good drainage. They are prone to rot if overwatered, especially in cool, damp conditions.
Watering Sedums
Sedums are generally quite hardy and forgiving. They also prefer to dry out between waterings. Some varieties, like ‘Burro’s Tail’, have plump leaves that store a lot of water, meaning they can go longer without a drink.
Watering Sempervivums (hens and Chicks)
Sempervivums are incredibly resilient and can tolerate a wide range of conditions. They prefer well-draining soil and should be allowed to dry out between waterings. They are particularly drought-tolerant once established.
A Table of General Guidelines (remember to Adapt!)
While not a substitute for checking your plant, this table provides a very rough starting point. Actual frequency will vary significantly.
| Succulent Type (General) | Growing Season (Approx.) | Dormant Season (Approx.) | Frequency (Growing Season) | Frequency (Dormant Season) |
|---|---|---|---|---|
| Common Rosette Succulents (Echeveria, Sempervivum) | Spring – Summer | Fall – Winter | Every 1-3 weeks (when dry) | Every 4-8 weeks (when dry) |
| Trailing Succulents (Sedum morganianum) | Spring – Summer | Fall – Winter | Every 1-2 weeks (when dry) | Every 3-6 weeks (when dry) |
| Cacti | Spring – Summer | Fall – Winter | Every 2-4 weeks (when dry) | Never or very rarely (when dry) |
| Aloes and Haworthias | Spring – Summer | Fall – Winter | Every 2-3 weeks (when dry) | Every 4-6 weeks (when dry) |
Important Note: This table is a rough guide. ALWAYS check the soil moisture and observe your plant’s condition before watering. Factors like light, temperature, humidity, and pot type will drastically alter these timelines.
Final Verdict
Mastering watering succulents, how often, boils down to observation and understanding. Prioritize well-draining soil and pots with drainage holes. Always check the soil moisture by touch before watering, and when you do water, do so thoroughly. Allow the soil to dry out completely between waterings, especially during the plant’s dormant period. Pay close attention to your succulent’s specific type, its environment, and the season. By avoiding common pitfalls like overwatering and misting, you’ll cultivate happy, healthy succulents that thrive for years to come.
