How to raise marigolds, breeding methods and matters needing attention / shading in spring, summer and autumn

Marigold, friends who have seen it should be impressed, it is colorful, golden sparkling, just like a golden lantern, deeply loved by flower friends. In life, many people want to bring marigolds into their homes and decorate their homes. How to raise marigolds? The following is the marigold culture methods and matters needing attention carefully arranged by the editor, very detailed, friends who want to raise must have a look.

First, how to raise marigolds and understand their habits

Indoor farming is not as good as the wild. If we want to raise a plant well, we must first understand its habits. So how to raise calendula, the editor will bring you marigold culture methods and matters needing attention from the aspects of soil, light, temperature, watering, fertilization, pruning and so on. Let's move on.

2. Culture methods and matters needing attention of potted calendula

1. Soil

How to raise potted marigolds, the first thing is to choose the soil. According to the growth habits of calendula, if you want it to grow well, you'd better prepare a slightly acidic soil with loose, fertile and good drainage.

Note: calendula has strong adaptability and is not picky about the soil. we can also choose general soil, as long as it is not alkaline.

2. Lighting

In the marigold culture method, the light is we should pay special attention to, especially in spring, summer and autumn, we should put the pot under shade conditions to maintain. The reason for this is that marigolds can not lack of light, but can only shine in weak light.

Note: in spring, summer and autumn, if maintained in direct sunlight, it will cause marigold leaves to turn yellow, fall off, grow very slowly or enter a semi-dormant state. In winter, calendula should be given direct sunlight to facilitate its photosynthesis and flower bud formation, and to blossom and bear fruit.

3. Moisture / humidity

Calendula likes the humid environment, so we should water frequently, but we should pay attention to not too much watering during the growth period, just keep the soil moist, the key point is to pay attention to humidity. Spray in time when the temperature is high, increase the air humidity, and try to control the humidity at 75-85%.

Note: in the process of raising calendula, we should spray water in time to increase humidity, preferably 1-3 times a day, increase the frequency of spraying in sunny days, and reduce spraying in cloudy and rainy days. But excessive spray, heading is easy to be infected by bacteria and rot, so spray should also pay attention to the water quality.

4. Fertilization

After watering, let's talk about fertilization, which is also very important in the culture of marigolds. Once there is enough fertilizer, the marigold can blossom more and more. Specific amount: during the growing period, fertilize once every half month.

Note: marigolds like fertilizer, fertilization should not be too little, once the fertilizer is insufficient, the flowers will obviously become smaller and degenerate.

5. Temperature

How to raise marigolds, the temperature should also be properly controlled, it is best to keep it at 7: 20 ℃. When the winter temperature is more than 10 ℃, the marigold grows too much. With the increase of temperature in summer, the stems and leaves grow vigorously, the flowers become smaller and the petals decrease significantly. Therefore, the temperature is high and low is not good, it must be appropriate.

Note: marigolds like a warm environment, once the temperature is too low, we should add film protection, otherwise the leaves are vulnerable to freezing damage. In the maintenance throughout the year, attention should be paid to controlling the temperature, opening windows in time for ventilation, and spraying water to cool down the indoor temperature.

6. Pruning

In the marigold culture methods and matters needing attention, the above points must be done, and the next pruning, we can pay attention to. Specific pruning methods:

① cuts off the branches with old and yellow leaves every two months. As long as the temperature is right, it can blossom all the year round.

② leaves no seeds at flowering stage, and cuts off the withered flowers, which is beneficial to flower branch germination, more flowering and prolonged flowering period.

7. Pest control

In the process of marigold culture, it will inevitably be disturbed by diseases and insect pests, of which the common diseases and insect pests are Fusarium wilt and downy mildew. When the temperature rises gradually in early summer, leaf spot disease will also occur in calendula. In this regard, what we should do is to follow the disease and pest control methods of calendula, corresponding to spraying.

How to raise calendula? Culture methods and matters needing attention of Calendula

Calendula, also known as golden calendula, sober flower, everlasting chrysanthemum and so on, is an annual herb of the genus Calendula in Compositae. The flowers of calendula are colorful and have high ornamental value, so they are often planted in the indoor courtyard. At the same time, marigold is very popular because it has the effects of improving appetite and lowering blood pressure. So, how to raise calendula? Now the marigold culture methods and matters needing attention are introduced as follows.

I. Culture methods of Calendula

1. Spring, summer and autumn shading: calendula can not be exposed to strong light, spring, summer and autumn need to be shaded in time, if the temperature during the day exceeds 25 ℃, do not directly put in the sun, otherwise the leaves will obviously become smaller, the distance between the branches will be reduced, the leaves at the bottom will gradually turn yellow and fall off, and the growth of the plant will gradually slow down and even infiltrate semi-dormant state. In winter, because the temperature is not high, it can give direct light and promote photosynthesis, which is conducive to the formation of flower buds, flowering and fruiting of calendula. After the plant blossoms, the plant can be maintained indoors for 10 to 15 days, and then moved to the outdoor shade environment for one month, so alternate maintenance is conducive to the accumulation of plant nutrients and prolong the flowering period.

two。 To warm, avoid extreme heat: calendula likes warm climate, afraid of extreme heat, summer temperature higher than 34 ℃ will be poor growth; not resistant to frost, winter temperature below 4 ℃ will enter dormancy or even death. The most suitable growth temperature of marigold is 15-25 ℃. In the maintenance of the whole year, attention should be paid to the control of temperature, timely opening of windows and cooling by spraying water to control the indoor temperature.

3. Pruning: cut off the branches with old and yellow leaves every two months, as long as the temperature is right, it can blossom all the year round. Coring is usually carried out twice before flowering to promote the germination of more flowering branches: one to two weeks after potting, or when the seedling is 6-10 cm tall and has more than six leaves, remove the tip and retain the lower 3-4 leaves to promote branching. After 3-5 weeks of the first coring, or when the lateral branch grows to 6-8 cm long, the second coring is performed, that is, the top tip of the lateral branch is removed and the 4 leaves under the lateral branch are retained. After two coring, the plant type will be more ideal and the number of flowering will be more.

4. Control humidity, spray water in time: calendula likes humid environment, control humidity at 75-85%, spray water in time to increase humidity during maintenance, 1-3 times a day, high temperature in sunny days, appropriately increase the number of water spraying, lower temperature in cloudy and rainy days and reduce water spraying times appropriately. But excessive spray, heading is easy to be infected by bacteria and rot, so spray should also pay attention to the water quality.
