Caring for cactus and succulents is rewarding, but it’s important to understand the basics, especially when it comes to watering. Overwatering or underwatering can cause these plants to become unhealthy. In this article, we’ll explore how often you should water your cactus and succulent plants, taking into consideration factors like environment, plant type, and growing conditions.
Understanding Cactus and Succulents
Cactus and succulents are two plant families that thrive in dry, arid environments. They are well-known for their ability to store water in their stems, leaves, or roots. This adaptation allows them to survive in places with little water, making them very low-maintenance compared to other plants.
Despite their hardy nature, they still require proper care to flourish in your home or garden. One of the most important aspects of care is understanding their water needs.
The Importance of Proper Watering
Watering is one of the most common mistakes people make when caring for cactus and succulents. Too much water can lead to root rot, a condition where the roots start to decompose because they are constantly sitting in wet soil. On the other hand, too little water can cause these plants to dry out and eventually die.
Knowing the right time to water these plants requires understanding their growing habits. Cactus and succulents have unique water storage abilities, so they don’t need frequent watering. Here’s a breakdown of how often you should water these plants.
Factors That Affect Watering Frequency
Several factors determine how often you should water your cactus and succulents. These include the season, environmental conditions, type of plant, and the type of soil it’s planted in.
1. Season: Watering in Different Seasons
Cactus and succulents typically go through a period of dormancy in the colder months, which means they require less water. In the spring and summer, when these plants are actively growing, they may need more frequent watering.
-
Spring and Summer (Active Growing Season): During the growing season, the plant absorbs water for growth. This is the time when watering should be more frequent, but still only when the soil is dry. In general, you should water once every 7-10 days, depending on the plant’s size and environment.
-
Fall and Winter (Dormancy Period): In winter, most cactus and succulents enter a dormant phase. They grow very slowly or stop growing altogether. During this time, the plant uses very little water, so you should reduce the watering frequency to once every 2-4 weeks.
2. Light and Temperature
Cactus and succulents love bright sunlight and warmth. The more sunlight they receive, the faster they will dry out, which means they will need more frequent watering.
-
Bright, Direct Sunlight: If your plants are in a location with plenty of sunlight, the soil will dry out faster. As a result, you may need to water them more frequently.
-
Low Light or Shade: If your cactus or succulent is in a shaded or low-light area, the soil will dry out slower, so you won’t need to water as often.
Temperature is also a big factor. During the hot summer months, the plant will need more water. On the other hand, cooler temperatures, especially in the winter, will reduce the plant’s water needs.
3. Pot Type and Soil
The type of pot your cactus or succulent is in plays a huge role in how often you need to water. Pots with drainage holes allow water to escape, which helps prevent water from pooling at the bottom of the pot and causing root rot.
-
Pots with Drainage: These pots allow excess water to flow out, which is crucial for preventing waterlogging. With proper drainage, cactus and succulents can tolerate watering less frequently.
-
Pots without Drainage: If your plant is in a pot without drainage, you need to be especially careful not to overwater. Without drainage, the water can build up at the bottom of the pot, leading to root rot.
Similarly, the type of soil matters. Cactus and succulents require well-draining soil to allow the water to pass through quickly. You can purchase cactus or succulent soil mixes, or create your own by adding sand or perlite to your regular potting mix.
4. Size and Type of Plant
Different cactus and succulent species have different water needs. Some are more drought-tolerant, while others may require a little more water. Similarly, smaller plants use less water, while larger plants may need more.
-
Small Plants: Smaller succulents like Echeveria or Haworthia have shallow root systems and don’t need a lot of water. Water them less frequently, and always make sure the soil has completely dried out before watering again.
-
Larger Plants: Larger succulents, such as Agave or Aloe Vera, have deeper root systems and can store more water. These plants may need more water during their active growing season but still require well-drained soil and proper watering techniques.
5. Humidity Levels
Cactus and succulents thrive in low-humidity environments. High humidity can make the soil retain moisture for longer, and over time, this can increase the risk of root rot. If you live in a humid area, you may need to water less frequently.
However, if the air is dry, you may need to water slightly more often. Just remember to always let the soil dry out before watering again.
How to Tell When Your Cactus or Succulent Needs Watering
The key to proper watering is observation. It’s important to allow the soil to dry completely between waterings. Here are some easy ways to tell if your cactus or succulent needs water:
1. Stick Your Finger in the Soil
A simple method to check soil moisture is to stick your finger into the soil about 1-2 inches deep. If the soil feels dry, it’s time to water. If it still feels moist, wait a few more days before checking again.
2. Use a Moisture Meter
A moisture meter is a tool that can help you check the moisture level of the soil accurately. It measures how much water is left in the soil and can help you avoid overwatering. These meters are available in most gardening stores.
3. Weight of the Pot
Another way to check for moisture is by lifting the pot. If the pot feels light, the soil is dry, and it’s time to water. If it feels heavy, the soil still has moisture.
4. The Appearance of the Plant
When succulents and cacti need water, they may start to look shriveled or wilted. The leaves might become soft, and some species might even change color, turning from green to yellowish or reddish.
In contrast, if you overwater a cactus or succulent, the plant may develop soft, mushy spots. The roots may start to rot, and the plant may begin to look sickly or discolored.
Watering Tips for Cactus and Succulents
Here are some simple tips to ensure your cactus and succulent plants stay healthy:
1. Water Deeply but Infrequently
When you do water, make sure to water deeply, soaking the soil thoroughly. This helps the roots to grow deeper, which makes the plant more drought-tolerant. Avoid shallow watering, as it encourages weak roots.
2. Don’t Water on a Set Schedule
Instead of watering on a strict schedule, always check the soil before watering. Each plant and environment is different, so the frequency of watering can change.
3. Use Room Temperature Water
Use room temperature water when watering your plants. Cold water can shock the roots, while hot water can damage them.
4. Let Water Drain
Always let excess water drain out of the pot to prevent water from sitting at the bottom. This helps reduce the risk of root rot.
5. Choose the Right Soil
Make sure your cactus and succulent plants are planted in well-draining soil. A good cactus or succulent mix contains sand or perlite, which improves drainage and keeps the soil from staying too wet.
Conclusion
Knowing when and how often to water cactus and succulents is essential for their health and growth. These plants are hardy and can survive in dry conditions, but they still need proper care. By understanding the factors that affect watering needs—such as light, temperature, pot type, and humidity—you can help your cactus and succulent plants thrive.
Remember to always let the soil dry out between waterings, and make sure the pots have proper drainage. In the right conditions, your cactus and succulents can live a long and happy life with minimal watering. Happy planting!
