Can I use general-purpose fertilizer for succulents? 

While it’s possible to use general-purpose fertilizers on succulents, it’s not the ideal choice. General-purpose fertilizers often have higher nitrogen (N) content, which promotes lush foliage growth. Succulents, however, prioritize root and flower development over excessive foliage. Therefore, using a fertilizer specifically formulated for cacti and succulents with a balanced N-P-K ratio is recommended.

Here’s why a specialized fertilizer is preferable:

  • Balanced Nutrition: Cactus and succulent fertilizers typically have an N-P-K ratio of 2-7-7 or similar, emphasizing phosphorus (P) and potassium (K). These nutrients promote strong root systems and vibrant flowering, aligning with the needs of most succulents.
  • Avoiding Nitrogen Overload: Excess nitrogen from general-purpose fertilizers can encourage excessive leaf growth, making your succulents more susceptible to etiolation (stretching) and weakening their overall structure.
  • Preventing Nutrient Imbalance: Succulents are adapted to thrive in nutrient-poor environments, and using a specialized fertilizer ensures they receive the right balance of nutrients without overloading them with excessive nitrogen.

If you only have access to general-purpose fertilizer, you can still use it on your succulents, but exercise caution. Dilute the general-purpose fertilizer to half or even a quarter of the recommended strength to reduce the nitrogen concentration. Additionally, consider supplementing with a phosphorus and potassium-rich source to provide the balanced nutrition that succulents need.

Should I fertilize newly planted succulents? 

Fertilizing newly planted succulents is generally not recommended immediately after transplanting them into new soil. Here’s why:

  • Establishment Period: When succulents are freshly planted, they need time to acclimate to their new environment and establish their roots. Fertilizing during this period can stress the plants, as their primary focus should be on root development.
  • Risk of Burn: Newly transplanted succulents are more susceptible to fertilizer burn because their root systems are not yet fully developed. Applying fertilizer at this stage can lead to nutrient toxicity, leaf damage, or even plant death.

To ensure a smooth transition for your newly planted succulents, it’s advisable to wait at least a month or two before introducing fertilizers. During this period, focus on providing them with proper lighting, well-draining soil, and adequate watering to promote root growth and overall health. Once they have settled in and show signs of active growth, you can begin a gentle fertilization regimen.
