How to water succulents without killing them

While succulents are drought-tolerant plants, and their gorgeous leaves are made to store water, it's essential to know how to properly water them to help them thrive. 

Here's how to water succulents correctly, according to Nathan Heinrich, a horticulturist and owner of his namesake botanical design firm.

How often should you water succulents?

Since succulents are water-storing plants, they don't require a regular watering schedule.

"There is no exact rule about how many times per month you should water your succulents because there are so many factors to consider," said Heinrich. "Soil type, plant variety, seasonal weather, temperature, climate and humidity all have an effect on how often you should water your succulent plants."

Heinrich says there is one simple rule that will help you determine when to water succulents so you can keep them healthy and happy no matter where they're planted: When the soil of your succulent is dry to the touch, it's time to water.

"Do not water when the soil is damp or has any noticeable moisture when you feel the top of the soil with the tip of your finger," he says. "In the same way, you can sense dampness on your clothes in the dryer, you can also check for moisture in your succulent's soil with a light touch."

"It is very easy to over-water succulents, so make sure you water only when they actually need to be watered rather than when you feel like watering," he adds.

How to water succulents indoors

Heinrich says that potted succulents grown indoors follow the same basic watering rules as all other succulents--only water when the soil is dry. You should water them thoroughly when the soil at the top of the container feels dry to the touch.

"An excellent way to water a potted succulent is to place it in a shallow bowl or saucer in the kitchen sink or bathtub," he says. "Then, slowly and gently add water to the pot until the water has run out, and fill up the bowl you are watering in. Let the succulent soak up as much water as it wants for the next 30 minutes."

"After [the plant] has soaked up water and the soil is completely saturated, take it out of the bowl and let any excess water drain out into the sink before returning it to a nice, bright and sunny -- but not too hot -- location in your home," he adds.

You also want to avoid putting your succulents against hot glass from a window with direct sunlight as this can scorch the leaves.

How to water succulents outdoors

Heinrich says that you can use the same watering method as indoor plants if you have small outdoor potted succulents. But if you have large, heavy pots with lots of soil, you should water them thoroughly when they are dry and then let them dry out before you water again.

"If you're watering succulents planted in the ground, pay attention to how moist the soil is before you water," he says. "Sandy soils dry out faster than heavy clay soils, so be aware of how quickly or slowly your soil dries out. If you get regular rain every month of the year, you might never need to water succulents that are planted in the ground."
