Succulents are incredibly popular plants for indoor and outdoor gardens due to their striking appearance, resilience, and relatively low maintenance requirements. However, one of the most common mistakes made by succulent owners is improper watering. Unlike typical houseplants, succulents have unique water requirements, and understanding when they need water is crucial for their well-being. In this article, we will explore the signs that indicate when your succulent needs watering, how to avoid common pitfalls, and some best practices for keeping your succulents healthy and thriving.
Understanding Succulent Water Storage
Before diving into the signs of when your succulent needs water, it’s essential to understand how these plants store water and why they need less frequent watering than other plants. Succulents have specialized tissue that allows them to store water in their leaves, stems, and roots. This adaptation helps them survive in arid environments, where water is scarce.
Succulents typically require water only when their internal stores are depleted. Overwatering can be just as harmful as underwatering, as their thick, fleshy leaves and stems can easily rot if exposed to excessive moisture. Therefore, determining when to water requires careful observation and understanding of your plant’s environment.
Signs That Your Succulent Needs Water
1. Wrinkled or Shriveled Leaves
One of the most noticeable signs that your succulent needs water is when the leaves start to shrink, wrinkle, or appear shriveled. Since succulents store water in their fleshy leaves, any reduction in water supply causes them to lose their plump, full appearance. The leaves may become thinner and lose their vibrant color, particularly around the edges. If your succulent’s leaves are showing these signs, it’s time to water.
2. Dry or Cracked Soil
A quick way to check if your succulent needs water is to feel the soil. Succulents typically thrive in well-draining soil, so when the soil is dry and cracks easily, it’s an indication that the plant is running low on moisture. Be sure to check several inches below the surface; a dry top layer does not always mean that the entire root zone is dry. Succulent roots extend deep into the soil, and moisture near the surface can evaporate quickly, especially in warm environments.
3. Yellowing or Drooping Leaves
Yellowing leaves are often a sign of a succulent that has been underwatered for too long. When a succulent doesn’t receive enough water, it will prioritize survival by sacrificing older leaves. These leaves lose their vibrant green color and become yellowish or pale. In some cases, the leaves may droop, appearing soft and bent.
If you notice yellowing or wilting leaves, it’s a clear sign that the plant is not receiving enough moisture. However, be aware that yellowing can also indicate overwatering or other stress factors, so it’s essential to rule out these possibilities before watering.
4. Leaf Loss
Succulents, especially types like jade plants and aloe, may shed leaves as a self-protection mechanism when they lack water. If you see a significant number of leaves falling off, particularly the lower ones, it is a clear indication that your plant is struggling with dehydration. While some leaf drop is normal, excessive leaf loss can signal that your succulent needs to be watered urgently.
5. Soil Pulling Away from the Edge of the Pot
In some cases, when the succulent is very dry, the soil will begin to shrink and pull away from the sides of the pot. This occurs because the soil is dehydrated and has contracted as a result of moisture loss. The empty space between the soil and the sides of the pot is a clear indication that the plant needs water. If you see this happening, it’s time to hydrate your succulent.
6. Cupping or Curling of Leaves
Some succulents, especially those with thick, fleshy leaves, may exhibit a cupping or curling shape when they need water. This occurs as the plant conserves moisture by closing its leaves inward. The leaves may look like they are “frowning” or puckering, a result of the plant’s natural defense mechanism to minimize water loss.
While this sign is not always an emergency, it is a clear indicator that your succulent is drying out and could benefit from a drink. Once watered, you’ll likely notice the leaves returning to their normal, full shape.
Best Practices for Watering Succulents
1. Water Deeply, but Infrequently
Succulents thrive with deep, infrequent watering rather than frequent shallow watering. Watering deeply encourages the roots to grow deeper into the soil, which makes the plant more drought-tolerant. When you water, do so thoroughly, ensuring that water drains out from the bottom of the pot. Avoid allowing the plant to sit in water, as this can lead to root rot.
A good rule of thumb is to water only when the soil has dried out completely. Depending on the environment (temperature, humidity, etc.), this could be anywhere from once a week to once a month. Check your plant regularly to ensure that you are following the proper watering schedule.
2. Choose the Right Potting Mix
To ensure that your succulents don’t stay soggy after watering, use a well-draining potting mix. Standard potting soil holds too much moisture, which can lead to root rot. Instead, opt for a cactus or succulent mix, which typically contains a higher ratio of sand or perlite to promote drainage. Additionally, ensure that your pot has drainage holes at the bottom to allow excess water to escape.
3. Consider the Season and Environment
Succulents often need less water during the cooler months when they are in a dormant phase. During the growing season, typically spring and summer, succulents may require more frequent watering as they actively absorb water to fuel growth. Environmental factors such as temperature, humidity, and light levels also influence a succulent’s water needs.
In high-humidity environments or during the rainy season, your succulent may not need water as often. Conversely, in very hot or dry conditions, it may require more attention.
4. Avoid Watering at Night
Watering succulents at night is not ideal because the water takes longer to evaporate. This can create a damp environment that encourages mold and root rot. Always aim to water your plants during the day when the temperature is warmer, and excess moisture can evaporate more quickly.
5. Use Proper Watering Tools
Using the right tools for watering can help you avoid overwatering or underwatering. A watering can with a long, narrow spout allows for more controlled watering, especially for plants in small pots. Alternatively, a spray bottle can be useful for lightly misting the soil without soaking it. Be mindful of the amount of water you apply to prevent waterlogging.
Avoiding Common Watering Mistakes
1. Overwatering
While under-watering is a concern for succulents, overwatering is just as dangerous. Succulents are more likely to suffer from root rot if they are watered too frequently or if the water does not drain properly. Overwatering can cause the roots to become waterlogged and oxygen-starved, leading to the breakdown of root tissue. To avoid overwatering, always check the soil moisture before adding more water.
2. Not Adjusting Watering Frequency for Seasonal Changes
Succulents’ water needs can fluctuate with the seasons. In the warmer months, when the plant is actively growing, they may need more frequent watering. However, in the cooler months, their growth slows down, and their need for water decreases significantly. Keep an eye on your plant’s activity level and adjust your watering schedule accordingly.
3. Watering Too Shallowly
A common mistake is watering only the top layer of the soil. Succulent roots typically grow deeper into the soil, so it’s essential to ensure that the water reaches the lower layers. Shallow watering can encourage surface-level roots and may not fully hydrate the plant.
Conclusion
Proper watering is one of the most critical aspects of succulent care. These fascinating plants are designed to thrive in dry conditions, but they still need water—just not too much. By paying attention to the signs of dehydration, such as wrinkled leaves, dry soil, and yellowing, you can ensure that your succulent remains healthy. Understanding the right watering practices—such as watering deeply but infrequently and using well-draining soil—will go a long way in helping your succulent flourish. With a little observation and care, your succulents can thrive in even the most challenging environments.
In the end, when in doubt, it’s always safer to wait a little longer between waterings than to risk overwatering. Succulents are resilient plants, and they will thank you with vibrant, beautiful foliage that can last for years to come.
