Sunflower is a very popular indoor plant because it not only beautifies the home environment but also brings fresh air. In order to take good care of sunflower, it is necessary to understand some basic maintenance knowledge. The following is the maintenance knowledge of sunflower.
1. Planting technology
1. Soil: Sunflower needs well-drained and nutrient-rich soil with a pH between 5.0 and 7.5. It prefers medium to slightly wet soil, but avoid overwatering.
2. Light: Sunflower needs plenty of sunlight to grow, but it should not be exposed to strong sunlight for a long time, otherwise it will cause the leaves to turn yellow and grow slowly. In general, you need at least 4 hours of direct light per day. In winter, sunflower can be slightly shade-tolerant, but it also needs to be well-lit.
3. Temperature: Sunflower prefers a warm environment and is suitable for growing at 20 to 35 degrees Celsius. The temperature range it is able to tolerate is between 5 and 40 degrees Celsius.
4. Watering: Sunflower needs moist soil, but avoid standing water. In dry weather, water should be sprayed frequently to increase humidity.
5. Fertilization: Sunflower needs sufficient nutrients, and compound fertilizer or diluted flower fertilizer should be applied once a month.
6. Pruning: Regular pruning can help keep it in beautiful shape and promote its growth. In general, you can prune once a year to cut off dead branches, diseased branches, and excessively long branches.
2. Pest control
Common pests and diseases include leaf spot, scale insects and red spiders. If leaf spot is found, fungicides can be used to control it, and for scale insects and spider mites, insecticides can be used to control it. At the same time, keeping the environment well ventilated and avoiding overwatering is also an important measure to prevent pests and diseases.
3. Reproduction methods
1. Split propagation: Split propagation is the most commonly used propagation method for Loose Tail Flower. In the spring, the mother plant is removed from the pot, divided into several bushes, and planted in a new pot.
2. Seeding propagation: Seeding propagation usually takes place in the spring, sowing the seeds after soaking them in water for a few days. Keep the soil moist and make sure there is good air circulation.
3. Tissue culture: Tissue culture is a method of rapid propagation by extracting plant tissues and cultivating them to generate new plants. This method is often used for large-scale reproduction.
Regardless of the method used, the health and growth of the plant needs to be ensured. During the breeding process, maintain the right temperature, light and moisture, and fertilize regularly. In this way, healthy sunflower plants can be successfully propagated.
