This specialized fertilizer is formulated specifically for desert plants. It provides a balanced mix of nutrients, including nitrogen, phosphorus, and potassium, tailored for cacti. Use during the growing season for optimal results.
2. Liquid Seaweed Fertilizer
Seaweed-based fertilizers are rich in trace minerals and growth hormones. They promote healthy root development and enhance overall vigor. Dilute according to package instructions and apply monthly during the growing season.
