Chrysanthemums are elegant and graceful flowers that are widely loved by people. However, chrysanthemums have specific fertilizer requirements. Improper fertilization can lead to problems such as stunted growth and unattractive flowers. This article will introduce the knowledge and techniques for fertilizing chrysanthemums to help you care for them healthily.
Nutritional Requirements of Chrysanthemums
Chrysanthemums require sufficient nutrients to support their normal growth and flowering process. This mainly includes elements such as nitrogen, phosphorus, and potassium, as well as trace elements.
Fertilization Timing for Chrysanthemums
The best time to fertilize chrysanthemums is generally in spring and autumn. In spring, fertilize at the beginning of the growing season to increase the plant's nutrient reserves; in autumn, fertilize after the flowering period to help the plant accumulate nutrients and grow.
Choice of Organic and Chemical Fertilizers
Both organic and chemical fertilizers can be used for chrysanthemums. Well-rotted compost is the best choice for organic fertilizer; for chemical fertilizer, choose a compound fertilizer or one that is balanced in plant nutrients.
Nitrogen Requirements for Chrysanthemums
Nitrogen is an important element for chrysanthemum growth and flowering. However, the application of nitrogen must be appropriate; too much can lead to delayed flowering, excessive vegetative growth, and other problems.
Phosphorus Requirements for Chrysanthemums
Phosphorus can promote the development of the chrysanthemum root system and improve the quality of the flowers. However, the application of phosphorus should not be excessive, otherwise it can easily lead to poor nutrient absorption by the plant.
Potassium Requirements for Chrysanthemums
Potassium can increase the disease resistance and stress tolerance of chrysanthemums, and it can also promote photosynthesis. However, the application of potassium must also be appropriate; otherwise, it can easily lead to plant wilting and yellowing of leaf margins.
The Effect of Trace Elements on Chrysanthemums
Trace elements also have a significant impact on the growth and flowering of chrysanthemums. For example, elements such as iron, zinc, and boron can promote the formation and opening of flowers, while elements such as sulfur and calcium can improve the plant's stress resistance and adaptability.
Application Methods for Chrysanthemum Fertilization
The application methods for chrysanthemum fertilization are generally divided into basal fertilizer and top dressing. Basal fertilizer should be applied before spring soil preparation, while top dressing can be applied timely during the growing season or flowering period.
Foliar Fertilization for Chrysanthemums
Foliar fertilization is a method for quickly supplementing nutrients. It can be used to remedy chrysanthemums that are malnourished or lack trace elements.
Precautions for Chrysanthemum Fertilization
There are some details to pay attention to when fertilizing chrysanthemums. For example, fertilization should not be too dense; leave a buffer period. Do not pour fertilizer directly onto the plant; mix it into the soil. Pay attention to controlling the amount when applying fertilizer, and do not over-fertilize.
Symptoms of Under-fertilization and Over-fertilization in Chrysanthemums
Both under-fertilization and over-fertilization can affect the growth and flowering of chrysanthemums. Symptoms of under-fertilization mainly include yellowing of the plant and slow growth; symptoms of over-fertilization include excessive vegetative growth and delayed flowering.
Methods for Storing Chrysanthemum Fertilizer
Knowing how to store chrysanthemum fertilizer is essential knowledge for anyone who grows them. Fertilizer should be stored in a dry, ventilated place, away from direct sunlight and moisture.
Evaluating the Effectiveness of Chrysanthemum Fertilization
The evaluation of the effectiveness of chrysanthemum fertilization mainly includes factors such as the size, color, and number of flowers. If the chrysanthemums are growing healthily and blooming vibrantly, it indicates that the fertilization is effective.
Precautions for Choosing Chrysanthemum Fertilizer
When choosing fertilizer for chrysanthemums, pay attention to its nutritional content, quality, and production date. Also, select the appropriate type of fertilizer based on the different growth stages.
This article has introduced the relevant knowledge and techniques for fertilizing chrysanthemums. It is hoped that it can help everyone care for their chrysanthemums healthily, allowing them to grow healthier and bloom more beautifully.
