What are the cultivation methods and precautions for French marigold?

French marigold likes sunlight, but it can also bloom when planted in partial shade. It is not demanding about soil. It tolerates transplanting, grows quickly, and is very easy to cultivate and manage. Seeds that fall to the ground can grow on their own under suitable temperature and humidity conditions, making it a flower with very strong adaptability. In southern China, its flowering period is from March to May and from August to December. It takes only 70 days from sowing to flowering. Seedlings raised in early spring can be grown in a greenhouse without heating, and after the late frost they can be planted in courtyards, flower beds, or pots.

(1) Light regulation

French marigold is a sun-loving plant, and both growth and flowering require sufficient sunlight. Sufficient light also helps prevent the plant from becoming leggy. In hot seasons, direct sunlight should be avoided, and shading and cooling should be provided around noon.

Temperature

Basically, French marigold can grow well between 10°C and 30°C. A few points to note are: the winter temperature should be kept above 5°C, so it is less likely to suffer cold damage; before flowering, the temperature is best kept between 12°C and 15°C; in daily care, the temperature is best kept at 20°C or below 20°C.

Water and fertilizer

Water and fertilizer are very important for French marigold. When watering, make sure the soil was dry beforehand, then water thoroughly, but be careful not to let it become too dry. Fertilizer is generally applied once every 7 to 10 days, but in the low-temperature winter season, fertilization should be reduced. Generally, some base fertilizer should be applied first when planting, and if the soil fertility is insufficient, additional topdressing is needed.

The above is an introduction to how to grow foliage French marigold. Next, let us look at what else should be noted about French marigold?

How to grow French marigold: cultivation methods and precautions for French marigold

French marigold is a herbaceous plant introduced into China from abroad. It is grown for its flowers, which are most commonly orange-yellow, and its flowering period is in summer each year. Many people now like to grow it, but before growing it, it is necessary to master some cultivation techniques in advance; otherwise, the French marigold being grown may not grow well.

How to grow French marigold

1. French marigold likes places with plenty of sunlight, and the suitable growing temperature is around 20°C. When growing it, make sure to provide enough light duration, which is good for flowering.

2. French marigold is relatively cold-resistant. When the air temperature is not lower than 6°C, it will not freeze to death, so no special attention to temperature is necessary.

3. When watering French marigold, make sure there is no waterlogging. Water thoroughly each time, and keep the soil moist but on the dry side. Do not let it become too wet, otherwise it will affect the growth of French marigold.

4. When growing French marigold, an appropriate amount of compound fertilizer can be added to the soil. If the fertilizer is found to be insufficient during later growth, just add more fertilizer.

5. French marigold is relatively easy to grow and does not have many pests or diseases. Only at the seedling stage may moth larvae chew the leaf surface. Once found, deal with it promptly by spraying pesticide.

6. French marigold is propagated by seeds. After each flower matures, it produces many seeds. Collect them well and plant them in the soil the next spring, and French marigold will grow.

Cultivation methods for French marigold

1. Light. French marigold is a light-loving plant and needs sufficient sunlight when being grown. Generally, spring and autumn can meet the light needs of French marigold, but note that in the hot summer, direct sunlight should be avoided, and shading should be provided at noon, though do not shade too much.

2. Temperature. Basically, French marigold can grow well between 10°C——30°C. A few points to note are: the winter temperature should be kept above 5°C, so it is less likely to suffer cold damage; before flowering, the temperature is best kept between 12°C——15°C; in daily care, the temperature is best kept at 20°C or below 20°C.

3. Water and fertilizer: Water and fertilizer are very important for French marigold.

For fertilization, generally fertilizer can be applied once every 7——10 days, but in the low-temperature winter season, fertilization should be reduced. Generally, some base fertilizer should be applied first when planting, and if the soil fertility is insufficient, additional topdressing is needed.

Precautions for growing French marigold

1. Potting. Generally, French marigold seedlings need to be potted when they grow 2——3 leaves. When potting, a flowerpot with a diameter between 10——15 cm can be used. After potting, basically no repotting is needed.

2. Pests and diseases. The common disease of French marigold is root rot, which can be controlled by drenching the roots with thiophanate-methyl. The main pest is spider mites. Propagation. French marigold is generally propagated by sowing and cuttings. Sowing is done between November and March. Cuttings propagation can be done between June and August.

How to control the flowering period of French marigold

1. French marigold controls its flowering period by adjusting the sowing date. To regulate the flowering period of French marigold, the simplest way is to control the sowing date and cutting time. Calculate when the flowers are needed, then decide when to sow and take cuttings. If propagation by sowing is chosen, after sowing in April in spring, it generally blooms in 70-80 days. If earlier flowering is needed, it can be placed in a greenhouse, and it can bloom before May.

2. French marigold controls its flowering period by controlling sunlight. French marigold has extremely strong adaptability. It begins to bloom one after another from May 1 and does not finish until October 1, so it can also be sown in summer. In addition, French marigold is a short-day flower, and shorter daylight conditions are favorable for flowering, so shortening daylight when it is still a seedling can make it bloom earlier.

The cultivation methods for French marigold are actually not difficult. Generally, you can start with its growth habits, and when growing it, be sure to pay attention to issues such as light and fertilizer and water. During cultivation, its flowering period can also be controlled through some techniques. The above has introduced this in detail, and everyone can pay more attention to it.
