Decoding the Watering Requirements of Indoor Succulents

An essential and crucial aspect of indoor succulent care is understanding watering needs. Well-watered succulents have a vibrant aesthetic appeal and increased longevity. Probably the most common mistake succulent caregivers make is concerning watering. Overwatering can cause as much damage to your indoor succulent as under watering.

Watering succulents can seem ambiguous because no strict frequency applies to all. Besides, the textures, colors, and sizes of succulents vary significantly, implying that their watering requirements equally differ. Let’s dive deeper and unravel the watering requirements for indoor succulents for healthier and happier plants.

Understanding Succulents’ Requirement for Water

Succulents are unique plants, and they have adapted to survive in harsh environmental conditions. Their Latin name, ‘succus’, means juice or sap which refers to their water-storing capacity. The thick and fleshy leaves of succulents store water to survive drought in their native desert habitats.

However, the ability to store water means succulents utilize water differently compared to other indoor plants. They can survive on minimal water amounts for extended periods, which most indoor plant varieties cannot withstand. Understanding this crucial aspect of their biology is key to perfecting their watering routine.

Dangers of Over-watering and Under-watering

Although succulents can survive with less water, it’s not an excuse for under-watering. Succulents still need to be watered regularly to prevent their health from deteriorating over time. An under-watered succulent may show signs like shrivelled or deflated leaves. The succulent leaves may also have dry tips, or the plant may have slow growth or grow in a lopsided manner because the moisture on one side is higher than the other.

However, a more rampant problem among succulent caregivers is overwatering. Over-watering suffocates the roots, preventing them from accessing oxygen, leading to root-rot. Symptoms of excessive watering include yellow or brown leaves, black spots, dropping leaves, and a rotten smell.

The idea when watering succulents is to achieve optimal balance. The correct amount of water varies depending on several conditions such as the type of succulent, pot size, pot material (ceramic or plastic), ambient temperature, humidity, and light conditions.

The Soak and Dry Method

The ‘soak and dry’ method is a watering technique proven effective in keeping succulents thriving. This method mimics a succulent’s natural habitat conditions, where cyclical torrential rains are followed by periods of drought. The philosophy is to soak the soil thoroughly then allow it to dry completely before the next watering session.

To implement this, pour water into the potting mixture until it runs out of the drainage holes. However, it’s essential to ensure the water does not sit atop the potting mixture without being absorbed. If the water doesn’t soak into the soil quickly, it is a sign that the soil is not well-draining, and you should alter the potting mix. Once the soil is soaked, leave the plant to dry entirely before watering next time.

The frequency of watering using the soak and dry method depends on how long your succulent’s potting mix takes to dry out. Factors like pot size and material, size and type of succulent, room temperature, humidity, and lighting affect the soil’s drying rate. As such, observe the drying speed of your succulent’s soil to adjust your watering frequency.

Pot, Soil, and Drainage

Three crucial components directly impact the watering of indoor succulents – the type of pot, the soil, and the drainage system.

First, the pot choice is vital since different materials have diverse effects on moisture retention and evaporation. Plastic pots retain moisture for longer than terracotta or ceramic pots that facilitate evaporation. Therefore, if you’re using plastic pots, you might need to water your succulents less often.

Additionally, the pot’s shape and size matter. Deep pots hold more moisture at the bottom, creating a conducive environment for root rot. On the other hand, wide pots allow more water evaporation, reducing the risk of waterlogging.

Second, the soil mix- succulents require a well-draining soil mix to avoid root rot and other overwatering repercussions. A good mix for succulents would be one that does not retain water for too long, such as a blend of perlite, coarse sand, and succulent/cactus potting mix.

Lastly, a proper drainage system with adequate drainage holes at the bottom of the pot offers an escape route for excess water. A drainage layer made of rocks or pebbles at the bottom of the pot can also increase drainage efficiency and discourage root rot.

Testing Soil Dryness

Critical to the watering process is knowing when the succulent is ready for its next watering. For this, you need to gauge the dryness of your succulent’s soil. The easiest method is using your finger- stick it an inch deep into the soil. Soil that clings to your finger and feels damp indicates adequate moisture levels, and you should hold off watering for a while. If the soil feels completely dry and crumbly, it’s watering time.
