Fertilization is a key point in planting to make its leaves greener and more colorful. How should periwinkle be fertilized? Let's take a look.

1. Apply base fertilizer

Catharanthus roseus likes loose and fertile soil environment, so proper fertilizer can be applied to the soil before planting. Humus fertilizer is recommended to improve soil nutrient content. In this way, periwinkle can have enough nutrients after germination, so as not to cause some trouble in growth due to insufficient nutrients.

2. Fertilization during growth period

The growth period of Changchun flower is the time when the fertilizer demand is the greatest. Insufficient fertilizer may affect its growth and delay its flowering. Therefore, at this time, it is generally necessary to fertilize once in about 10 days to make it grow rapidly. Compound fertilizer and liquid fertilizer can be applied to fertilizer. The best method is to apply liquid fertilizer after compound fertilizer once. In this alternate way, it is necessary to pay attention to the amount and scale of fertilizer application, whether it is compound fertilizer or liquid fertilizer. If the fertilizer is too little, the plant will grow poorly, and if the fertilizer is too much, it is easy to cause fertilizer damage and damage the plant.

Fertilization at flowering stage is mainly organic fertilizer, supplemented by compound fertilizer, applied once a month, or water-soluble fertilizer can be applied once every half month. The concentration should not be too high to promote fertilizer absorption by plants, so that flowers are more colorful and ornamental.

4. Fertilization in winter

In winter, the dormant period of periwinkle, when the plant will stop growing, the absorption capacity of the root system is weakened, and most of them rely on consumed nutrients to maintain. Therefore, fertilizer should be applied once before winter to supplement the nutrients of the plants, so that they can accumulate enough nutrients for winter, increase cold resistance, and make them safe for winter. However, fertilizer is not needed during dormancy period, only after overwintering, fertilizer is applied at the beginning of spring thawing to promote flower bud growth.
