So how do we raise such beautiful flowers at home? let me give you a brief introduction.

I. on the culture methods of Corydalis

1. Light

The European light for the initial growth of Corydalis is not very much, so the horn pansy forms a characteristic that is less sensitive to light. But Corydalis still like the sun, usually give some more light Corydalis will grow more branches. It doesn't affect its growth in the dark.

two。 Soil

If the soil is acidic sandy soil with ph between 5.5 and 6.5, it needs to be well drained and has a lot of organic matter. When sowing, you can mix peat and pearl salt at 1:1. The soil should be kept moist.

3. Temperature

The origin of Corydalis determines its tolerance to severe cold and even mild frost. Corydalis in warm areas such as the south can survive the winter. Corydalis can not be raised in places where the temperature is too high, 10 to 15 degrees is the best temperature, more than 30 degrees can not grow normally.

4. Fertilizer application

After the young leaves of Corydalis seedlings grow, 50 to 75ppm nitrogen fertilizer can be used, and then gradually increase the concentration to 100ppm. It is also necessary to supplement potash fertilizer appropriately, and the ratio of the two is 1: 1.5. Trace element solution should also be sprayed to supplement Fe,Mg.

5. Pest control

Corydalis may be destroyed by aphids, red spiders, thrips and other pests. We should pay attention to the cleanliness of the cultivation environment and not plant in places where there are pests. There are common leaf ring disease, downy mildew and so on. Controlling soil ph can also reduce the probability of corydalis getting sick.

Corydalis can't pour too much water, because it grows in a cool environment and gives off less water, so it doesn't need too much water. Pay attention to the preservation in the indoor, put in the outdoor Corydalis is difficult to have the best growth environment. Corydalis has relatively little demand for fertilizer, at least it will not burn fertilizer very much. The flowers raised at home should be fertilized.
