How many times does the multi-head chrysanthemum bloom in a year?
As the颜值担当 among the Compositae plants, the multi-head chrysanthemum is deeply favored by gardening enthusiasts for its beautiful and colorful flowers. Although this perennial herbaceous plant blooms only once a year, scientific care can achieve an extended flowering period for appreciation. This article will provide a detailed analysis of the blooming patterns of multi-head chrysanthemums and pruning care techniques after flowering.
I. Analysis of Multi-Head Chrysanthemum Blooming Period
1.1 Annual Blooming Characteristics
Multi-head chrysanthemum is a single-season flowering plant, which naturally blooms only once a year, but different varieties show significant differences in flowering periods. By properly combining early, middle, and late maturing varieties, a continuous flowering effect from early summer to late autumn can be achieved, with an overall viewing period of up to 7 months.
1.2 Variety Flowering Distribution
• Early flowering series (May-July): Varieties like月子 and 白丹 bloom first• Middle flowering series (September-October): Varieties like 雪 and 嫔凯 bloom in succession• Late flowering series (November-December): Varieties like 阿丽埃塔 make a grand finale
II. Post-Flowering Pruning and Care System
2.1 Four-Step Precision Pruning Method
① Remove spent flowers: Immediately cut off the spent flowers after they fade, leaving 2-3 healthy leaves below the flowers② Shape the branches: Remove the excessive growth branches/weakened branches to maintain an open plant shape③ Disinfection treatment: Apply a solution of carbendazim to the cut ends to prevent infection④ Nutrient recovery: Collect the pruning materials to make compost
2.2 Supporting Care Measures
After pruning, apply phosphorus and potassium fertilizers to supplement nutrition, keep the soil moist but avoid waterlogging. It is recommended to slightly loosen the soil to promote the germination of new buds. In the northern regions, anti-freezing measures should be taken before winter.
III. Long-Term Care Suggestions
Combined with a three-year plant renewal system, retain 1/3 of the healthy mother plants each year for division propagation. Regularly monitor the soil pH value, maintaining it at a slightly acidic environment of 6.0-6.5. During the high-temperature summer season, pay attention to shading protection to avoid leaf damage from strong sunlight.
Through scientific flowering period management and systematic pruning care, not only can the single flowering period of multi-head chrysanthemums be extended to over 60 days, but it can also promote plant rejuvenation, laying the foundation for flowering in the following year. It is recommended to establish an individualized care calendar based on local climatic characteristics.
