Ornamental plants primarily for foliage require a heavier application of nitrogen fertilizer; variegated flower plants need more phosphorus and potassium fertilizers; for plants that are pruned frequently, increasing the ratio of phosphorus and potassium fertilizers is recommended to promote new branch growth.

For large-flowered flowers such as chrysanthemums and dahlias, apply a moderate amount of fertilizer before the blooming season to ensure all buds open beautifully and vibrantly.

3. For flowering plants primarily grown for fruit, it's essential to moderately control fertilization and watering during the blooming period, and apply fertilizers during the fruiting stage to achieve the desired outcome of abundant flowers and fruits.

4. Root flowers require more phosphorus and potassium fertilizers to ensure the bulbs are well-filled; for flowering plants, such as fragrant flowers, applying more phosphorus and potassium fertilizers during the blooming period can enhance the scent and flavor of the flowers.

5. Azaleas, camellias, gardenias, and other flowers require acidic fertilizers rather than alkaline ones to ensure lush foliage and vibrant blooms.
