How to propagate marigolds? Detailed explanation of seed sowing and cutting propagation methods

Marigolds can be propagated by cuttings in summer; they root easily and grow into plants quickly. Cut 8-12 cm young shoots from the mother plant as cuttings, remove the lower leaves, insert them into the potting soil, 3 plants per pot, water thoroughly after inserting, shade slightly, and they will root after 2 weeks. Then, gradually move them to a sunny spot for routine care, and they will bloom after about 1 month. Today, the editor brings you the propagation methods for marigolds.

Marigold propagation methods:

1. Seed sowing propagation

Marigolds are generally propagated by seed sowing.

Marigold seeds germinate easily, and sowing is generally done in late March to early April in spring. Sow the marigold seeds into the growing medium; a seeding pot can be used. After sowing, keep the temperature at 15-20°C, and seedlings will generally emerge in one week.

After the marigold seedlings emerge, let them continue to grow. When the marigold seedlings grow to 5 cm with 7 to 8 leaves, they can be transplanted and planted out.

When propagating marigolds by seed, a certain temperature must be maintained. After sowing, cover with soil and water to ensure sufficient moisture. From sowing to blooming takes about 50 days. If sown in summer, they need 60 days to bloom. When selecting seeds, choose the fruits formed after autumn flowering; they should be fresh and glossy. This is because seeds formed from summer flowering have a low germination rate.

2. Cutting propagation

Marigold cutting propagation is carried out in May-June in summer.

Take young shoots about 10 cm long as cuttings, remove the lower leaves after cutting, and insert them into sand or vermiculite. After inserting the marigold cuttings, water thoroughly and provide shade; they generally root in about 10 days, and once rooted they can be transplanted.

After transplanting, marigold care is relatively simple. Generally after transplanting, gradually move the marigolds to a sunny spot for routine care, and they will bloom after about 1 month. During the period from planting out to flowering, fertilize once every 20 days with a thin, well-rotted liquid fertilizer to keep the soil fertile. Water appropriately to keep the soil slightly moist. Pinching can be done several times to increase branching and encourage marigolds to bloom more.

Marigold is a relatively common flower in summer with high ornamental value, and it is grown in many regions of our country. As more people grow it, questions about its propagation methods have also become a matter of concern. So how do you propagate marigolds? And what are the propagation methods for marigolds? Below, the editor will walk you through it.

I. How to propagate marigolds

The question of how to propagate marigolds can actually be broadly divided into two types: seed sowing propagation and cutting propagation. As long as the methods are mastered correctly, the survival rates of both sowing and cuttings are very high. The specific marigold propagation methods are explained in detail below; let's take a look.

II. Marigold propagation methods

Seed sowing propagation

1. Soil selection

Among marigold propagation methods, seed sowing is a relatively commonly used method. When carrying out seed sowing propagation, we first need to choose soil. We can choose sandy soil with high looseness; this kind of soil has good drainage, allowing the seeds to absorb nutrients better and germinate faster.

2. Sowing method

As for how to sow and propagate marigolds, the method is actually very simple. First, place the selected soil in a flower pot and press it level, then evenly scatter the marigold seeds on the soil surface, then cover with 2 cm of soil and water. When watering, just water thoroughly once, but be sure not to let water accumulate. After that, they will germinate in about 1 month.

3. Follow-up care

After the marigold seeds germinate, we can begin care. If you don't know how to care for them, you can refer to the article on marigold growing methods, which has detailed instructions, so the editor will not go into too much detail here.

Cutting propagation

1. Cutting selection

Among marigold propagation methods, cuttings are used relatively less often than sowing, but although used less, the survival rate is not low. When carrying out cutting propagation, we first need to choose the cuttings, that is, the branches. When selecting, it is best to choose branches that are robust and free of pests and diseases, as this will greatly increase the survival rate.

2. Cutting method

To know how to propagate marigolds by cuttings, we first need to find a stick-like object about as thick as the cutting, poke a hole in the center of the potting soil, then insert the cutting into it and press the soil level. After that, water thoroughly and roots will form in about 15 days.

How to propagate marigolds, seed sowing and cutting propagation methods

Marigold sowing is generally done from late March to early April each year.

The soil for sowing marigolds is generally vermiculite or a prepared nutrient soil, and the soil must be sterilized.

Scatter the seeds on the soil, and after sowing cover the seeds with vermiculite. Be careful to maintain the moisture of the medium, and at the same time carry out short-day treatment for 14 days. The optimal temperature for seed germination is 17-20°C, and all seedlings emerge within 5-8 days.

After the seeds emerge, gradually increase the light, spray with a fine-nozzle watering can, and maintain the moisture of the medium. When the seedlings produce 3 true leaves, prick out and transplant once, moving the seedlings into bull's-eye pots filled with No. 1 growing medium, 1 seedling per pot. After potting, water thoroughly, allow about 5 days to recover, gradually increase the light, and carry out normal seedling-stage management.

Cutting propagation is best carried out from May to June each year, and it is very easy to survive. Choose young shoots as cuttings, about 10 cm long is enough, insert them into a sand bed or peat soil, and keep the room temperature at about 19°C-21°C. After inserting, they generally root in 10-15 days, and cutting plants generally bloom in 30-40 days.
