Why does this watering method work?
Succulents are generally native to areas where the soil drains quickly and water is heavy, but infrequent. Think about cacti (a subcategory of succulents) out in the desert… They get flash floods of water, with storms lasting 24-28 hours, followed by weeks without any water at all.
While your succulents, especially indoors, don’t need a watering schedule this extreme, they will benefit from the “soak and dry” approach.
With a deep watering the succulent has plenty of access to water. During the “drought” between watering, the succulent will begin to grow new roots, searching for more water.
The soak and dry method helps the succulent develop a large, healthy root system which will enable it to withstand longer periods of drought than most other plants.
DO NOT use a spray bottle for watering. Constant watering with small amounts of water, like with a spray bottle, will produce a weak root system that can’t withstand very long periods of drought.
That means if you don’t water for a couple days your succulent will die. Or if you don’t get the water deep enough when you spray with a spray bottle, the succulent will die. So don’t do it 🙂
Soak and dry… soak and dry…
