How does marigold reproduce? Introduction to the propagation method of marigold

Marigold, which has an auspicious meaning, has long been regarded as a flower of respect for the elderly. it is originally from Mexico and has lax requirements on the soil. it is better to have a rich, well-drained sandy loam, like a warm, humid and sunny environment, and mainly breed seeds. It can also be propagated by cuttings. let's take a look!

Seed propagation of marigold

1. Spring sowing: sowing seeds in the open field seedbed from late March to early April. Because the seeds offer light, they should be covered with soil and watered after sowing. The optimum temperature for seed germination is 20: 25 ℃, and the seedling emerges one week after sowing. The germination rate is about 50%. When the seedling grows to 5 cm high, it is transplanting once, and then when the seedling grows 7-8 true leaves, it is planted.

2. Summer sowing: in order to control the plant height, it can also be sown in summer and blossom 60 days after summer sowing.

Cutting propagation of marigold

Marigold can be cut in summer, which is easy to root and grow into seedlings quickly. Cut 8cm twigs from the mother plant as cuttings, remove the lower leaves, insert them into the basin soil, insert 3 plants in each pot, pour enough water after insertion, slightly shade, and take root after 2 weeks. Then, gradually move to a sunny place for daily management, and it can blossom in about a month.

Growth conditions of marigold

1. Temperature: the suitable temperature for the growth of marigold is 15: 25 ℃, and the suitable temperature for flowering is 18: 20 ℃. The relative air temperature of the growing environment is required to be 60-70%, and the winter temperature is not lower than 5 ℃. When the high temperature in summer is more than 30 ℃, the plant is overgrown, the stem and leaf are loose, and the flowering is few. Below 10 ℃, the growth slows down.

2. Illumination: marigold is a light-loving plant, sufficient sunlight is very beneficial to the growth of marigold, the plant is short and strong, and the flowers are colorful. The sun is insufficient, the stems and leaves are soft and slender, and the flowers are few and small.

3. Soil: marigold is not strict on soil, and it is better to use sandy loam with fertile and good drainage.

Propagation methods of marigold:

The main propagation methods of marigold are sowing and cutting propagation.

(1) sowing and propagation: the sowing time is generally chosen to sow in the hotbed between March and April. Soak the seeds in warm water (35-40 ℃) for 3-4 hours before sowing, then remove them and filter them with clean water. Sowing time should be selected when there is no wind and sunny days. It is required that the soil surface of the seedbed should be leveled and watered once, and then sowed after water infiltration, and then covered with a very thin layer of fine soil. The suitable temperature for seed germination of marigold is about 20 ℃. It can germinate 4-5 days after sowing, and the seedlings are exposed to soil quickly. When the number of true leaves reaches 2-3, one transplant is needed, and it can be planted in the open field in late May. Usually it can blossom 70-80 days after sowing. Summer sowing can also be carried out to meet the use during the National Day. Marigold sown in summer can blossom in 50-60 days.

(2) cutting propagation: the cutting propagation of marigold can be carried out between May and June. The shoots of plants with strong growth and free of diseases and insect pests should be selected as cuttings. Cut the shoots about 10 cm long at the top of the branches, punch holes with thin sticks, cut them in the open bed, compact the soil, build a shade, maintain the moisture of the soil and air, take root in about 2 weeks, come out of the nursery in 3 weeks, and bloom in about 35-42 days. Because of its short growth time, cuttings can blossom when the plant is short, and its flowering period is easy to be controlled, which is especially suitable for the application of flower bed layout.

Sowing and propagation of marigold

Marigold is generally propagated by sowing and reproduction.

The seeds of marigold are easy to germinate and are usually sown from late March to early April in spring. If you plant marigold seeds into the culture soil, you can choose to use a sowing pot. After sowing, the temperature is guaranteed to be 15 ℃ and 20 min, and the seedlings will usually emerge within a week.

Let the seedlings continue to grow after the marigold emerges. When the seedlings of marigold grow to 5 cm and have 7 to 8 leaves, they can be transplanted and planted.

Marigold should be sown and propagated at a certain temperature. After sowing, it should be covered with soil and watered to ensure sufficient moisture. It takes about 50 days from sowing to flowering. If it is sown and propagated in summer, it will take 60 days to bloom. In the selection of seeds, we should choose the fruit after flowering in autumn, which should be fresh and shiny. Because, the germination rate of seeds that bloom in summer is low.

Cutting propagation of marigold

The cutting propagation of marigold is carried out from May to June in summer.

Take about 10 cm long twigs as cuttings, cut off the lower leaves, and insert them into sand or vermiculite. Marigold cutting after watering enough water, and need shade, generally about 10 days can take root, rooting can be transplanted.

It is easy to manage marigold after transplanting. Generally, after transplanting, marigold should be gradually moved to a sunny place for daily management, and it can blossom after about 1 month. During the period from planting to flowering, marigold can be fertilized every 20 days, and thin and rotten liquid fertilizer is needed to ensure fertile soil. Water properly to keep the soil slightly wet. Heart picking can be carried out many times to increase branches and promote marigold to blossom more.
