There is a common misconception that succulents don’t need much water. While it’s true that they can go longer periods of time without it, they will not thrive in a drought-like situation. My general rule of thumb is to water your plants when the soil is completely dry—typically once a week during hotter months and a little less often when the weather cools. You can kill succulents by overwatering, so make sure the soil is totally dry between waterings.
To actually water the plants, give the soil a good soak so that the water runs out of the bottom of the pot. Try to water the soil, not the plant, if possible. Letting water settle on the leaves can cause rot, in addition to leaving unsightly markings.
If the pot you’re using doesn’t have drainage holes, don’t soak the soil. Instead, give it more of a “sip.” In this book, we will be creating arrangements in containers without drainage holes, such as teacups, Mason jars, and glass terrariums. Because succulents do better in containers that drain well, we will always layer the bottom of the container with pebbles to create an alternative drainage system. Although this isn’t the ideal situation for growing succulents, they can certainly survive. Repot your plants if they begin to look as if they are struggling in a container without proper drainage.
If you water your indoor plants outdoors, be sure to keep them protected from direct sunlight, as the sudden change in sun exposure could shock them and cause the leaves to be scorched and scarred. On very slow-growing succulents, a sunburn can scar a plant for the remainder of its lifetime.
