Complete guide to fertilizing Catharanthus roseus!

Growth properties of Vinca roseus

It likes a warm and slightly dry environment, and it is best to have longer light exposure. The temperature is generally between thirteen and twenty-four degrees Celsius, which is most conducive to its growth. However, it has poor cold resistance in winter and the temperature should not be lower than ten degrees Celsius. Catharanthus roseus does not like an overly wet or overly waterlogged potting soil environment, so flower owners must pay attention to this. In addition, Catharanthus roseus likes light and fertile soil, and is not tolerant to poor soil and alkaline soil. Generally, breathable sandy soil is best. Compacted soil is not conducive to its growth.

What fertilizer should be applied to vinca rosea

Catharanthus roseus is not tolerant of waterlogging and is most afraid of being soaked in the flowerpot. Fertilizer should be applied with some water-soluble fertilizer, which should be added every seven to ten days. In the cold winter, the amount of fertilizer should be relatively reduced. It mainly depends on the soil medium. If it is ordinary soil, you can mix compound fertilizer in the soil when potting and use it as base fertilizer. When the plant shows the need for top dressing, add water-soluble fertilizer.

How to fertilize Catharanthus roseus

During the seedling stage of Catharanthus roseus, the bud core will be removed once, and then normal fertilization will begin, which is to water with water-soluble fertilizer every seven to ten days as mentioned above. When the flowering period begins, organic fertilizer should be used as the main fertilizer, supplemented by compound fertilizer, and added once a month. This can not only ensure the brightness of the flowers during the flowering period, but also prolong the flowering period of vinca roseus to achieve the maximum ornamental value.
