How to grow Fritillaria

1. Maintenance methods

1. Temperature: Fritillaria thunbergii is suitable for growing in a cooler environment. It has a very strong cold resistance and can grow normally between seven and twenty degrees. If the temperature is higher than twenty-five degrees, it is likely to wither or dehydrate, and the leaves will become soft, so the temperature must be lowered in the summer. At the same time, the south is not suitable for breeding. However, it must be kept warm in winter and not be too cold.

2. Watering: Observe the soil and make sure it is slightly moist. It does not need to be too wet, otherwise most of the branches and leaves at the bottom will wither or even rot. If the roots are soaked in stagnant water for a long time, they will rot, so the newly opened flowers will turn yellow. In winter, you should water sparingly and wait until the soil is dry before watering again.

3. Light: Warm and sufficient light will make the flowers bloom more brightly. If the light is not enough, it will not meet its flowering needs. At the same time, except for the strong light in summer, it can receive light normally in other seasons. If the light is not enough, it needs to be supplemented with light.

4. Fertilization: Before planting, you need to apply enough base fertilizer, which can promote the growth and development of seedlings. Fertilizer should be applied from time to time during the subsequent growth process, depending on the growth condition of the plant. At the same time, fertilization should be stopped in summer, because at this time it will enter a dormant period due to the relatively high temperature, so you cannot continue to fertilize, otherwise it will grow too tall.

2. Breeding techniques

1. Reproduction: Sowing is the main method of reproduction. The best time is before the snow from September to October each year. Row sowing is to sow the seeds into the soil and then cover it with grass and branchless branches. Spot sowing is to divide the undried fruits into several parts, and then bury them in the dug holes. Pay attention to the distance between them and cover them with three centimeters of soil. Although this method is more laborious, the survival rate will be slightly higher.

2. Pruning: There are many branches and leaves at the root of Fritillaria, so it needs to be pruned from time to time, but it should not be pruned too heavily. Cut off some dense branches and leaves to increase ventilation at the roots.

3. Problem diagnosis and treatment

1. Disease: Rust will occur on the back of the leaves, causing the plant to die early. It can be controlled by using methyl thiophanate solution.

2. Pests: Root-knot nematode disease can occur mainly due to improper root ventilation and excessive watering, and can be eliminated by turning the soil.
