Growth habits of Catharanthus roseus

The most suitable temperature is 20 ℃-33 ℃, like sunshine, avoid dampness and fear waterlogging, general soil can be cultivated, but saline-alkali soil is not suitable, it is better to use sandy or humus-rich soil with good drainage, ventilation and ventilation, flowering and fruiting almost throughout the year.

Morphological characteristics of Catharanthus roseus

Apocynaceae, Catharanthus roseus. Perennial herbs or subshrubs, often cultivated annual. Plant height ca. 30-60 cm, erect, distally much branched, base Lignified. Leaves opposite, membranous, Obovate moment rounded. Dark green glossy, leaf veins obviously white, Cymes terminal or axillary, with 2-3 flowers, Corolla deep rose red or white, some with hearts, flowers 2.5-3 cm in diameter. From August to frost, the seeds are easy to crack and fall off when they are mature.

Distribution range of Catharanthus roseus

Native to the Mediterranean coast, India, tropical America. The history of Catharanthus roseus cultivation in China is not long, and it is mainly cultivated in the south of the Yangtze River, especially in Guangdong, Guangxi, Yunnan and other provinces (autonomous regions). Various provinces and cities in China have introduced many new varieties of Catharanthus roseus from the world, which are used for potted plants and planting troughs.

Culture method of Catharanthus roseus

First, sowing seeds

Catharanthus roseus is suitable for sowing or cutting, although the growth of cutting is not as good as seeds, but the speed is more intuitive. If the seed is collected, it should be picked along with the maturity, so that the growth ability of the seed will be better.

Second, temperature

The temperature of Catharanthus roseus germination is about 20-25 degrees, and the best time to sow seeds is from March to May. If you want the seeds to blossom early, you can keep them in a warm room and keep the temperature at about 20 degrees. When the outdoor temperature is warm, transplant to the outside.

3. Soil

In the cultivation of Catharanthus roseus, it is necessary to choose the soil with good drainage and the soil made of peat and perlite in the cultivation of Catharanthus roseus. After watering the soil with carbendazim and water, wait until it is slightly dry and then loosen it. After the soil is leveled, it can be used for planting.

Fourth, sunshine

Catharanthus roseus is a positive plant, so it likes plenty of sunlight, abundant sunlight can help the plant to grow, and the plant type will be more beautiful. Secondly, the sun is conducive to flowering, to ensure beautiful flowers and colors.

Notes on Catharanthus roseus:

Basin soil

The basin soil should choose the humus-rich and loose substrate or artificial culture soil. When the sowing seedlings grow 6 true leaves, put them in the pot and put them in the sunny place after planting.

Watering

During the growth period, the basin soil should be dry and wet to prevent it from being too wet or too wet, and avoid stagnant water.

Fertilizer application

Liquid fertilizer should be applied once a month, and available phosphate fertilizer should be added in the bud stage, which is beneficial to plant growth and flowering.

③ pick the heart

The heart needs to be removed for 1 or 3 times.

④ heat preservation

In winter, it can be placed in a greenhouse above 5 ℃ to survive the winter, and the pot soil is better than dry; when moved outside in spring, it can continue to grow and blossom after turning the pot and changing the soil. Propagation method of Catharanthus roseus

Sowing or cutting, sowing in the open bed at the beginning of April, or sowing in the greenhouse in advance between January and February, the germination temperature is about 20 ℃, after germination, it can be planted in a small pot when the Hebei leaves are 4-5, and then replace the corresponding large pot with the seedling growing up, cultivated in the open field, and plant the flower bed when the seedling height is 15-20 cm. Catharanthus roseus can also be cut during the growth period, but the cutting seedlings are not as robust as sowing seedlings and are used less.

Methods of Catharanthus roseus culture and matters needing attention in Catharanthus roseus culture

Catharanthus roseus is a plant with beautiful flowers. Its origin is on the Mediterranean coast of Europe. Catharanthus roseus blossoms almost all the year round and is a very common potted ornamental plant. Let's take a look at the daily cultivation methods of Catharanthus roseus.

Points for attention in the method of Catharanthus roseus culture 1. Fertile soil

Suitable for fertile and well-drained soil, resistant to barren soil, but do not be alkaline. Clayey soil with hardening and poor ventilation will result in poor plant growth, which will lead to yellow leaves of Catharanthus roseus, or even no flowering.

2. There is plenty of sunshine

Catharanthus roseus is a light-loving plant, there must be sufficient sunshine during the growing period, the leaves are green and shiny, and the flowers are bright. If you grow in the shade for a long time, the leaves will turn yellow and fall.

3. Temperature and humidity

Prefer a warm, slightly dry and sunny environment. The suitable temperature for growth is 18: 24 ℃ from March to July, 13: 18 ℃ from September to March of the following year, and the winter temperature is not lower than 10 ℃.

4. Watering control

Catharanthus roseus avoid dampness and fear of waterlogging, basin soil watering should not be too much, too wet affects growth and development. In particular, indoor winter plants should be strictly controlled watering, it is better to dry, otherwise it is easy to freeze. Open field cultivation, midsummer showers, pay attention to timely drainage, so as not to cause the whole area to die by waterlogging.

5. Fertilization control

When applying fertilizer, compound fertilizer and liquid fertilizer can be applied alternately every ten days. The bottom of the Catharanthus roseus pot soil should also be covered with a layer of base fertilizer as far as possible to ensure the nutrient content of the pot soil.

6. Pest prevention

Catharanthus roseus plants are poisonous, so they are more resistant to diseases and insect pests. The main diseases in seedling stage are: seedling quenching disease, Botrytis cinerea and so on. In addition, it is necessary to prevent the occurrence of fertilizer damage and drug damage in seedling stage. If it happens, it should be watered with clean water immediately to strengthen ventilation and reduce the harm.

7. Pruning

Catharanthus roseus is a herbaceous plant, which is more suitable for potted plants, but it should be careful not to let the plant grow too high, affecting indoor decoration and ornamental, so after surviving in the pot, it is necessary to pick the heart several times to promote multiple branches and more flowering, and the residual flowers must be cut off after flowering.

When Catharanthus roseus reaches the growing period, the demand for fertilizer will be relatively large, basically once every 10 days or so. We can choose water-soluble fertilizer for fertilizer.

3. Temperature management

Catharanthus roseus is a kind of plant that is resistant to high temperature but not cold, so when breeding, the temperature must be controlled well, and the temperature should not be too low. The most suitable temperature for the growth of Catharanthus roseus is between 20 °C and 33 °C. therefore, in the cultivation methods and matters needing attention of Catharanthus roseus, temperature is a point that needs attention.
