After potted carnations bloom, a series of treatments are needed to ensure their healthy growth and promote the next flowering. Here are some key steps: 1. Cut off withered flowers
Purpose: To prevent withering flowers from consuming too much energy and nutrients, and to encourage plants to enter new growth stages.
Method: Use scissors or pruning shears to gently cut off from below the flower until it reaches the nearest leaf node or flower bud position, while retaining some leaves to help the plant continue photosynthesis. 2、 Provide sufficient sunlight
Importance: Sunlight is a key factor for the normal growth and flowering of carnations.
Measure: Place potted carnations in a bright location near the window indoors, ensuring at least 6 hours of bright light per day. If there is insufficient light, it can lead to problems such as excessive plant growth and poor flowering. 3、 Watering in moderation
Principle: Keep the soil moist but avoid over watering.
Method: Check the soil moisture and water the soil when it feels dry when touching the surface. Gently water with warm water to ensure that the water flows evenly throughout the entire soil basin. Follow the principle of "seeing dry and seeing wet", that is, wait until the surface of the soil in the pot becomes dry before watering. During high temperatures in summer, it is necessary to increase the frequency of watering to maintain normal plant growth and flowering. 4、 Regular fertilization
Importance: Fertilization can supplement nutrients, promote plant growth and flowering.
Method: After the flowering season ends, liquid fertilizer or controlled-release fertilizer suitable for flowers can be applied every 4 to 6 weeks according to the ratio and frequency indicated on the fertilizer packaging. Choosing fertilizers rich in phosphorus, potassium, and other elements can help promote the healthy growth of carnations and the formation of flower buds. 5、 Regular pruning
Purpose: To maintain healthy plant morphology and dense branches and leaves, and promote new growth.
Method: Use pruning shears or scissors to trim the branches and leaves of carnations. Cut off diseased leaves, withered branches, and excessively long branches. At the same time, branch growth can be promoted through methods such as picking the heart and topping. 6、 Control temperature
Suitable temperature: The suitable growth temperature for carnations is 15 ℃~25 ℃.
Measures: During high temperatures in summer, measures need to be taken to cool down; During low temperatures in winter, measures need to be taken to maintain insulation. 7、 Prevention and control of pests and diseases
Importance: Carnations are susceptible to pests and diseases, such as aphids, spider mites, powdery mildew, etc.
Method: Regularly check the growth status of plants and take timely prevention and control measures if pests and diseases are found. A combination of biological and chemical control methods can be used for prevention and control. At the same time, attention should also be paid to improving the growth environment of plants and enhancing their disease resistance. 8、 Basin replacement treatment
Timing: When plant growth is hindered or when the soil in the pot is compacted.
Method: Select a pot of appropriate size and replace it with new nutrient soil for planting. When changing pots, it is important to protect the root system from damage. After changing pots, watering should be done promptly to keep the soil moist, which is beneficial for the growth of new roots. 9、 Avoid direct sunlight and rain
Reason: Exposure to sunlight can cause flowers to wither too quickly, affecting the viewing effect, while rain can easily cause flowers to rot, which is not conducive to the normal growth and flowering of plants.
Measure: Place carnations in a well ventilated and shaded area for maintenance, while also avoiding exposure to rain.
Potted carnations require various treatments after flowering to ensure their healthy growth and promote the next flowering. These measures include cutting off withered flowers, providing sufficient sunlight, watering appropriately, fertilizing regularly, pruning regularly, controlling temperature, preventing pests and diseases, changing pots, and avoiding exposure to sunlight and rain.
