1、 Rational topdressing

Corydalis flower consumes a lot of nutrients. After flowering, the plant growth has been relatively weak, so topdressing should be used to supplement the nutrients consumed before. Because the flowering of Corydalis generally consumes phosphorus and potassium fertilizer, fertilization should also focus on this aspect, appropriately supplement phosphorus and potassium fertilizer, pay attention to thin fertilizer and frequent application, and never apply thick fertilizer

2、 Proper watering

Corydalis should be watered properly. When the basin soil is dry, it needs to be watered properly. One-time watering needs to be watered thoroughly to meet the water demand. In daily maintenance, water properly to keep slightly wet. In sunny weather, spray water in time to moisturize, but it cannot be sprayed on flowers to prevent premature withering of petals

3、 Replenish sunshine

It is a plant that needs a lot of sunshine for flowering and sufficient sunshine after flowering. If the light is insufficient, it will lead to the growth of branches, the flowers will wither in advance, and the flowers are not beautiful. After blooming, the flowers gradually wither, but also can not go out of light, but also need to maintain good sunshine

4、 Trim properly

After the flowers gradually wither, they need to be properly trimmed to cut off the broken flowers. For the flower branches that have bloomed, they also need to be properly cut off to reduce the consumption of nutrients
