We raise Catharanthus roseus. If we raise a plant in a flowerpot, we will make Catharanthus roseus blossom in large numbers by topping. However, even if the Catharanthus roseus is capped, if only one plant is raised in a flowerpot, the probability of Catharanthus roseus bursting is not great, so it is necessary to raise 3-4 plants in a flowerpot.

If you use flowerpots to raise 3-4 Catharanthus roseus plants, you need a bigger flowerpot, but not too big, because the flowerpot is too big for Catharanthus roseus to explode, so you can choose a flowerpot with a diameter of 25-35 cm.

Second, determine the size of the flowerpot according to the size of Changchun flower seedlings.

If it is a small seedling of Catharanthus roseus, you need a smaller flowerpot, which can be about 15 cm. If Catharanthus roseus is going to blossom, it needs a bigger flowerpot.

Two: Catharanthus roseus can be changed into a pot every two years.

If we transplant Catharanthus roseus in the early stage, it is more appropriate to use a smaller flowerpot in the seedling stage, so that when Catharanthus roseus grows for two years, it can be replaced with a larger flowerpot. Change pots for Catharanthus roseus. We can change pots in spring, because spring is the peak season for Catharanthus roseus.

Three: flowerpots should not be too shallow, because we need to apply base fertilizer when transplanting.

I saw many flower friends say that flowerpots should not be too deep, because Catharanthus roseus belongs to shallow-rooted flowers. Yes, the root system of Catharanthus roseus is really shallow, but when we transplant Catharanthus roseus, we need to spread a drainage layer at the bottom of the flowerpot and apply a base fertilizer, and the base fertilizer should be separated from the root system of Catharanthus roseus with soil, otherwise it will cause Catharanthus roseus to burn its roots.

How to transplant Catharanthus roseus?

One: the new flowerpot is soaked in advance, and the old flowerpot is washed and dried before use.

When we transplant Catharanthus roseus, we can prepare flowerpots in advance, which can be pottery pots, plastic pots, porcelain pots and pottery pots. If you use a new clay pot, you can soak it thoroughly in advance. If it is an old flowerpot, we can wash it and dry it for a while before using it, which will be more beautiful.

Second, choose the soil suitable for Catharanthus roseus growth.

Catharanthus roseus likes sandy soil, with loose soil, good air permeability, rich humus and smooth drainage. When we cultivate Catharanthus roseus, we can mix humus, garden soil and sand together.

Through our introduction, I believe everyone has a deeper understanding of how to maintain Catharanthus roseus in winter.
