What are the precautions for growing French marigolds?

Potting up

Generally, French marigold seedlings need to be potted up when they grow 2-3 leaves. When potting up, you can use a flower pot with a diameter between 10-15cm. After potting up, there is basically no need to repot.

That is all for today's content. After reading this article, I hope everyone will know how to grow French marigolds.

How to grow French marigolds: French marigold growing methods and precautions

The French marigold is a herbaceous plant introduced to China from abroad. It is grown for its flowers, which are most commonly orange-yellow, and its flowering season is every year in summer. Many people now like to grow it, but before growing it, you need to master some growing techniques in advance, otherwise the French marigolds you grow may not grow well.

How to grow French marigolds

1. French marigolds like places with plenty of sunlight. The suitable growing temperature is around 20°C. When growing them, pay attention to providing enough light time, which is good for flowering.

2. French marigolds are relatively cold-resistant. When the air temperature is not lower than 6°C, they will not be frozen to death, so there is no need to pay special attention to temperature.

3. When watering French marigolds, be careful that waterlogging does not occur. Water thoroughly each time, and keeping the soil moist but on the dry side is enough. Do not let it be too wet, otherwise it will affect the growth of French marigolds.

4. When growing French marigolds, you can add an appropriate amount of compound fertilizer to the soil. Later during growth, if you find that the fertilizer is not enough, just add more fertilizer.

5. Growing French marigolds is relatively easy, and there will not be too many pests and diseases. It is only when they are seedlings that moth larvae may chew the leaf surface. If found, deal with it promptly and spray pesticide.

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

French marigold growing methods

1. Light. French marigolds are plants that like light, and they need plenty of sunlight when being grown. Generally, spring and autumn can meet the light needs of French marigolds, but note that in the high-temperature summer, direct sunlight should be avoided, and shade should be provided at noon, but do not shade too much.

2. Temperature. Basically, French marigolds can grow well between 10°C——30°C. A few points to note are: the winter temperature should be kept above 5°C, so that cold damage is less likely to occur; 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 to French marigolds. When watering, make sure the soil was dry beforehand, and then water thoroughly, but be careful not to let it become too dry. When fertilizing, generally fertilize once every 7——10 days, but in the low-temperature season in winter, fertilization needs to be reduced. Generally, when planting out, apply some base fertilizer first. If the soil fertility is not enough, topdressing is also needed.

Precautions for growing French marigolds

1. Potting up Generally, French marigold seedlings need to be potted up when they grow 2——3 leaves. When potting up, you can use a flower pot with a diameter between 10——15cm. After potting up, there is basically no need to repot.

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

How to control the flowering period of French marigolds

1. French marigolds control the flowering period by adjusting the sowing date. To regulate the flowering period of French marigolds, the simplest way is to control it by controlling the sowing date and cutting time. Calculate the time when you want flowers, then decide when to sow and take cuttings. If you choose seed propagation, after sowing in April in spring, they generally bloom in 70-80 days. If you need them to bloom earlier, you can put them in a greenhouse, and they can bloom before May.

2. French marigolds control the flowering period by controlling sunlight. French marigolds have extremely strong adaptability. Starting from May 1, French marigolds bloom one after another, and it does not end until October 1. Therefore, you can also choose to sow in summer. In addition, French marigolds are short-day flowers, and shorter sunlight conditions can help flowering, so shortening sunlight when they are still seedlings can make them bloom earlier.

The growing methods for French marigolds are actually not difficult. Generally, you can start with their growth habits, and when growing them, be sure to pay attention to issues such as light, fertilizer, and water. During the growing process, you can also use some techniques to control their flowering period. There is a detailed introduction above, and everyone can pay more attention to it.
