When to sow Catharanthus roseus (a few months) the florescence of Catharanthus roseus

Flowers and plants all have a suitable time for its growth and germination. under such time conditions, the natural environment can provide the temperature, light and water that plants need. So when we grow at home, we also need to consider some of the growth laws of plants formed in nature, in order to make our breeding process more smoothly.

When does Catharanthus roseus sow

Sowing around March to May in spring, the temperature is the best between 20 and 25 degrees Celsius, and generally germinates at 14 to 21 days after sowing. Seedlings can be cultivated in early spring and can be cultivated in a warm spring.

The florescence of Catharanthus roseus

The flowering period of Catharanthus roseus is very long. Basically, when Catharanthus roseus blossoms, it begins from April to May. It usually lasts quite a long time. It blossoms continuously from spring to autumn, and can even blossom all year round. So it is called daily spring.

However, a single flower of Catharanthus roseus does not last long. It usually takes five days for a single flower to bloom.

Fertilization methods of Catharanthus roseus

1. What fertilizer should Catharanthus roseus apply

Catharanthus roseus is not resistant to waterlogging, most afraid of soaking in flowerpots, fertilization should also use some water-soluble fertilizer, once every seven to ten days, to the cold winter to relatively reduce the amount of fertilizer. It mainly depends on what medium the soil is, if the general soil can be mixed with compound fertilizer as base fertilizer when potting, and water-soluble fertilizer can be added when the plant shows that it needs topdressing.

2. How to fertilize Catharanthus roseus

In the seedling stage of Catharanthus roseus, it will undergo a bud core removal operation, and then begin normal fertilization, that is, the above mentioned seven to ten days for a cycle of water-soluble fertilizer. When the flowering period begins, the fertilizer is mainly organic fertilizer, supplemented by compound fertilizer, added once a month, which can not only ensure the bright flowering, but also prolong the florescence of Catharanthus roseus, and achieve the maximum ornamental value.

Pruning Catharanthus roseus

1. Pruning methods of Catharanthus roseus.

Catharanthus roseus is a herbaceous plant, suitable for potted plants, but it should be noted that its plant should not be allowed to grow too high, so as not to affect indoor decoration and ornament, so after surviving in the pot, it needs to be picked several times to promote multi-branching and multi-flowering of Catharanthus roseus, and the residual flowers need to be cut off after flowering.

In addition, it is also necessary to prune insect branches and strengthen fertilizer and water management. When pruning in winter and summer, insect branches and dry and dead branches should be re-pruned. At the same time, it is also necessary to strengthen fertilizer and water management, promote Catharanthus roseus to shoot, renew the crown and restore the tree momentum.

2. the heart-picking work of Catharanthus roseus

In addition to normal fertilizer and water management, the focus is on heart extraction and prevention and control of stem and leaf rot in the rainy season. The purpose of heart picking is to promote the branching of Catharanthus roseus and control the florescence at the same time. Generally speaking, when there are 4 or 6 true leaves, you begin to pick the heart, and when the new shoots grow 4 or 6 leaves, you should pick the heart for the second time, and it is best not to pick the heart more than 3 times.

The last heart pick has a direct impact on the flowering period. generally speaking, the last heart pick in autumn is 25 days away from the early flowering stage, and the last heart pick in summer is 3-5 days earlier than in autumn.

Catharanthus roseus can not be plucked, but in order to get a better plant type, it is best to pick the heart once or twice. For the first time, there were 3-4 pairs of true leaves, and the second time, 1-2 pairs of true leaves were left in the new branches. In the process of cultivation, regulators can usually be used, but paclobutrazol can not be used.

The reason why Catharanthus roseus is called Catharanthus roseus should include the reason for its long flowering period. Catharanthus roseus blossoms from the end of spring, and then it can bloom all the year round, just like it is permanent in spring. However, in order to maintain a long flowering period, the necessary procedures and methods of maintenance must be indispensable.
