How to care for and plant newly planted Vinca rosea (Cultivation methods and precautions for Vinca rosea)

Vinca rosea soil preparation

Catharanthus roseus has strong adaptability and does not have too many requirements for soil. If you plant it in the ground and sow a little seeds, it will grow well.

Potted vinca roseus has certain requirements for the soil. The soil for the potting must be loose, breathable, and have a certain degree of drainage, mainly to avoid water accumulation and root rot.

Soil preparation suggestions

We can use garden soil, leaf humus, river sand mixed and used, or we can use nutrient soil prepared with coconut coir, peat, etc. No matter what type of soil, it must be well drained, and it is not suitable to use soil that is too sticky.

Light requirements of Catharanthus roseus

Catharanthus roseus prefers a growing environment with sufficient light, and is also tolerant to partial shade. Under conditions of sufficient light, Catharanthus roseus can effectively carry out photosynthesis, grow well, and bloom more.

Long-term lack of light will affect the growth of Catharanthus roseus, causing adverse conditions such as excessive growth and yellowing of leaves.

Lighting recommendations

Catharanthus roseus can be maintained indoors or outdoors. For indoor maintenance, it can be placed under the window, balcony or other places with good light. It should not be placed in a room with poor light. Outdoor maintenance is the most ideal maintenance environment, and it can be maintained directly in the sun.

Water and fertilizer management for daily maintenance of Catharanthus roseus

There are generally two ways to plant vinca roseus, ground planting and potted planting. Ground planting is relatively simple to manage and does not require too much water and fertilizer to grow very well. Potted planting requires frequent watering and fertilization.

The requirements for water and fertilizer vary at different growth stages, so watering should be adjusted reasonably according to the growth period.

Water and fertilizer recommendations

Water the vinca roseus once after sowing, and then spray a little water when it is dry until the seedlings emerge. After the seedlings emerge, you can water them with light fertilizer to promote the growth of the seedlings. When the seedlings are about 10 cm, you can reduce watering appropriately to promote the growth of the root system .

After transplanting, you can follow the normal watering method. Usually watering can be carried out according to the principle of "watering when dry and watering when wet".

It grows fast in spring and autumn and cannot lack water. It needs more water in the hot summer. It needs very little water in winter, so don't water it too much.

As for fertilization, you can apply more nitrogen fertilizer during the seedling stage to promote rapid growth of seedlings, but the nitrogen fertilizer should not be excessive, otherwise it will easily cause excessive growth.

Catharanthus roseus can bloom from spring to late autumn. It requires a lot of fertilizer for flowering. After each bud appears, you can add appropriate amount of phosphorus and potassium fertilizers to promote flowering.

Pruning and pinching management of Catharanthus roseus

In order to maintain the plant shape, pruning of Catharanthus roseus should be started from the seedling stage.

When the seedlings grow to about 10 cm, pinch off the tips, which will promote the growth of side branches.

Keep 3-4 strong side branches, preferably in different directions. When the side branches grow to a certain length, pinch them again. Repeat this several times. This will allow the vinca roseus to grow more flowering branches and bloom more flowers when it blooms.

After each flowering, timely pruning of withered flowers can reduce nutrient consumption.

While cutting off the withered flowers, you can also shape the plant by cutting off some messy branches and branches that are too dense and affect ventilation, combing the inner branches, and cleaning up dead branches and rotten leaves in time.
