Fertilization can be started when the floating leaves grow. You can apply about 10 potassium sulfate ternary compound fertilizers or decomposed cake fertilizers; apply twice the fertility during the budding stage. Stop fertilizing at the dormant period to protect the lotus root.

One, base fertilizer

It does not require a lot of soil. The soil can be moist and sticky. Pond mud and paddy soil can be used as the main components of the lower layer. Among them, the pond soil where fish has been raised is the best. Be sure to apply base fertilizer before potting, which is conducive to the rapid growth of plants. Because the seedlings of the plant are relatively fragile and not suitable for premature fertilization, the role of base fertilizer is very important. For example, bone meal, decomposed cake fertilizer or other organic fertilizers are very good materials.

Second, top dressing

1. Growth period

At this time, the growth is fierce, and sufficient fertilizer must be provided. Fertilization can be started when the floating leaves just start to grow. You can apply about 10 potassium sulfate ternary compound fertilizers or decomposed cake fertilizers. After the standing leaves of the plant grow up slowly, the amount of fertilization can also be increased. The amount of fertilization each time is about twice that of the floating leaves. Generally, apply it once every 7-10 days. Pay attention to applying thin fertilizers frequently.

2. The pregnancy bud period

This is the beginning of gestation of flowers and fruits. Its nutrient consumption is also relatively large. It can increase the amount of phosphorus and potassium fertilizers. At the same time, pay attention to the rapid volatilization caused by high temperature weather.

When the flowers are open, you can reduce the amount of fertilizer to prevent the occurrence of fertilizer damage. Flowers and branches that have withered or withered can be pruned in time to avoid continuing to consume nutrients.

3. Dormancy period

At this time, it has entered a cold winter, and the branches and leaves were pruned after they were yellow. Only the solitary lotus root is still in a fragile state. It needs to be buried in the soil for maintenance. It can be added to the bottom of the pot before the plants are completely yellow. Add a small amount of fertilizer and let the plants survive the winter quietly.
