Can Vinca Rose be grown into an old pile (How to prune and grow Vinca Rose into an old pile)

Vinca roseus is a small grass flower that cannot be killed by the sun. It can always be found in green belts and flower beds. It blooms for more than half a year and does not rest until winter. It is really admirable!

When growing Catharanthus roseus into an old tree, it is best to shape it into a tree with full leaves and umbrella-like flowers, which also requires certain skills.

First, soil preparation

In order to maintain Catharanthus roseus into an old stump, in addition to providing it with suitable growing materials, it is also necessary to repot it and replace the soil with new one approximately every 2 to 3 years.

Once the planting material becomes compacted or lacks air permeability, it will affect the root growth of Catharanthus roseus, causing the roots to suffocate and die or become waterlogged and rotten.

It is recommended to mix one-third of each of garden soil, humus soil and freshwater river sand. This mixed soil can be used for repotting or new planting.

Second, a suitable growth environment:

Vinca roseus has a strong ability to adapt to the environment. As long as the summer temperature does not exceed 35 degrees Celsius, it can be placed in a location with sufficient light. Even if the light is not very long, it will only affect flowering but not growth.

The only drawback of Catharanthus roseus is that it is not cold-resistant. When the temperature drops to zero degrees, the young branches will freeze to death, and the old stumps will also die if the temperature is below zero for a long time. In winter, it can be brought indoors for winter maintenance when the temperature is close to 10 degrees Celsius.

When entering the room, make sure there is at least 3 hours of sunlight every day and that there is fresh air output.

Third, watering:

Improper watering of vinca roseus will cause root rot if too much water or root dryness if too little water. The watering method of vinca roseus is very simple. We have dealt with the drainage problem of the soil, and then watering can be done when the leaves droop slightly.

Keeping the planting material relatively dry will help it bloom. On the contrary, too much water will cause root rot and suffocation. In hot and dry seasons, you can spray the leaves at noon every day to cool them down.

Fourth, fertilization:

Growing flowers and grasses requires fertilization. Catharanthus roseus has a strong ability to tolerate barrenness. When fertilizing, pay attention to using thin fertilizers. Even if you can't grasp the ratio well, it's okay to dilute it with more water. Generally, fertilizing once a month is sufficient.

The recommendation for fertilization is to use organic fertilizer and supplement the elements of "nitrogen, phosphorus and potassium" at the same time. The fermented sheep dung balls can be buried shallowly in the shallow soil by loosening the soil.

Fifth, pruning:

If you want to maintain a better-looking old vinca, you must be ruthless in pruning. In spring and autumn, when the temperature is between 16 and 30 degrees Celsius, you can behead the vinca.

Keep the main trunk about 15 to 20 cm and then cut it. After cutting the trunk, new branches will grow out, and keep 3 to 5 branches to grow freely. When the branches grow to 15 cm, cut them back and then store more branches. Soon, a full semicircular crown will be formed.
