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 shoot growth.

For large-flowered flowers like chrysanthemums and daisies, applying an appropriate amount of fertilizer before the blooming season is necessary 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 phase, and to apply fertilizers during the fruiting stage to achieve the expected 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, applying more phosphorus and potassium fertilizers during the blooming period can enhance the fragrance and intensity of the flowers.

Dahlias, camellias, gardenias, and other flowers should avoid alkaline fertilizers and require acidic fertilizers to ensure lush foliage and vibrant blooms.
