There’s a common misconception that because succulents are hardy, they require no nutrition. Contrarily, succulents, like all living things, require food to thrive. That’s where fertilizing comes in. Determining how often to fertilize your succulents can be a bit of a challenge, as there is no one-size-fits-all approach. The frequency and quantity of fertilization can vary depending on the type of succulent, the soil it’s in, and the environmental conditions it is subjected to.
The Basic Rule of Thumb
Generally speaking, succulents should be fertilized once every month during the growing season, which typically falls between early spring and late summer. In the winter, most succulents are in a dormant period and don’t require additional feeding. However, it’s important to note that this is a broad guideline, and variations might be necessary based on specific plant needs.
Why Do Succulents Need Fertilizer?
Much like other plants, succulents use light for photosynthesis, creating their food. However, they still require additional nutrients to grow and stay healthy. Naturally, they would obtain these nutrients from the soil. But in a potted environment, soil nutrients can quickly deplete, and that’s when it becomes crucial to supplement with a fertilizer.
Choosing the Right Fertilizer
When it comes to choosing a fertilizer, a balanced water-soluble fertilizer (a 20-20-20 mix of Nitrogen, Phosphorus, and Potassium) often works well for a wide range of succulents.
Nitrogen aids in growth and development of the succulent’s leaves and stems, Phosphorus supports root growth and flower formation, while Potassium enhances overall plant health. Some succulent enthusiasts also recommend using a fertilizer with a lower Nitrogen ratio as too much can cause rapid growth leading to elongation, referred to as etiolation.
Understanding Specific Succulent Needs
Appreciating the diversity within the succulent family aids in better caregiving. Some succulents might require more frequent feeding compared to others. For example, fast-growing succulents like Echeverias will benefit from monthly fertilization during the growth season. On the other hand, slow-growers like Haworthias might only need to be fertilized twice or thrice during the entire active growth season.
