Succulents and cacti are adapted to survive in dry environments, which means they prefer infrequent but thorough watering rather than small amounts of water given regularly. The best method is to soak the soil completely, allowing water to run through the drainage holes, and then allow the potting mix to dry out fully before watering again.
This “soak and dry” approach mimics the natural conditions these plants experience in desert climates. Their thick leaves and stems store water, so they can tolerate longer dry periods between watering.
One of the most common mistakes is watering too frequently, especially in low-light indoor environments. When light levels are low, plants use water more slowly, and constantly damp soil can quickly lead to root rot. In fact, low light combined with frequent watering is one of the fastest ways to damage succulents and cacti.
Using the correct soil is equally important. These plants require a fast-draining potting mix that prevents moisture from lingering around the roots. Learn more in Your Complete Guide to Houseplant Soils, particularly the section on desert plants that need drainage.
A specialised mix such as Desert Mix Potting Mix, helps create the airy, well-draining environment these plants need to stay healthy indoors.
