How to plant seeds of Platycodon grandiflorum patchouli thistle? When will it blossom? How do you breed?

Patchouli thistle, alias Sheng Hong thistle, also known as salted shrimp flowers, hairy musk, butterfly grass, etc., so how to plant agastache thistle seeds? When will it blossom? How do you breed? It is understood that Huoxiang thistle prefers a warm growing environment and requires plenty of light. Huoxiang thistle is not cold-resistant, has a poor tolerance to high temperature, and grows poorly when the temperature is too high. However, the growth ability of patchouli thistle is relatively strong, more resistant to pruning.

How to plant the seeds of patchouli thistle?

1. Preparation of soil

Different flowers need different soil for sowing, so a good selection of soil plays an important role in the growth and development of patchouli thistle. The planting soil of Huoxiang thistle needs to use pastoral soil, and then add the same amount of agricultural fertilizer, and then add a small amount of mature fertilizer to mix evenly. After this preparation of soil, the seeds will germinate easily, and the developed patchouli thistle will grow very strong.

2. Sowing seeds

Because the seeds of patchouli thistle are very small, sowing becomes relatively difficult. The time of sowing is generally determined according to the flowering time of Huoxiang thistle, so its flowering time can be adjusted by adjusting the sowing time of Huoxiang thistle. If you need them to blossom around International Labour Day, you can sow them at the end of August and early September of the previous year, so you need to put them in a warm room for the winter, and you can't get out of the warm room until late April of the following year. In general, however, patchouli thistle is sown in a warm room in February or in the open field in April.

When sowing, you need to put the prepared soil into a basin, then flatten and press it, pour it thoroughly, and then put the seeds of patchouli thistle on the soil. The seeds of patchouli thistle do not need light, so you need to put a layer of soil on the top layer of the seed, but it should not be too thick to press the seed slightly. After about a week, you can see the seeds sprouting.

3. Colonization

Planting is done when the seeds sprout and grow a few leaves. First of all, you need to choose a suitable flowerpot, generally a flowerpot with a diameter of more than ten centimeters, and then the potted soil needs to be mainly pastoral and sandy, and then the seedlings of agastle thistle are planted in the soil, compacted, and then watered and placed in a cool place for about a week before they can be transplanted to a sunny place to grow.

4. Daily management

Do not water too much water, generally let the soil moist, early growth can be appropriate more water, so that the growth of patchouli thistle is good.

Fertilization, generally in the growth period can be applied once or twice organic fertilizer, thin fertilizer can be.

Because patchouli thistle likes the sun, it can bask in the sun more.

When will it blossom?

The period of flowering:

It can be said that this plant blossoms from January to December of the New year, so its flowering period should be calculated throughout the year.

Maintenance of flowering period:

1. The time and times of applying water

Because this kind of plant can blossom all the year round, it is necessary to manage the amount of water applied at all times. When we see that there are signs of whitening and drying on the surface of the soil in the potted plant, we can be drenched with water. it is worth noting that the amount of water must be sufficient, not half of the water. When entering the warmer season, because the plant grows very vigorously at this time, it should be watered twice a day to replenish water.

2. The amount of fertilizer applied

Due to the frequent flowering of this plant, the demand for nutrition is very large, we need to supplement fertilizer to it in time, so that it can absorb sufficient nutrients. In the peak season of its growth, that is, when the temperature is relatively high, you can water it with diluted fertilizer every 10 to 15 days, and you can appropriately add some phosphorus and potassium fertilizer to it, which can not only dwarf the plant, but also add the bright color of the flowers. so as to improve the ornamental value of flowers.

3. Pruning of plants

Because this kind of plant will blossom all the year round, and if we want to watch the plant, and want to have the beautiful sight of the compact and multi-flowered plants, we have to take measures to pick the heart of it many times. Generally pick the heart to hit the tip up to 3 to 4 times, after the first batch of flowers, the plant should be pruned in time. Generally speaking, we can keep the old branches that are 5 to 6 centimeters high, cut off all the upper parts, and cut off the branches that are too dense at the same time.

4. Maintenance of humidity

This plant likes to grow up in humid and slightly dry climates, so it requires air humidity of between 50% and 70%.

Third, how to reproduce?

1. Sowing and propagation of thistle

Huoxiang thistle seeds are relatively small, sowing needs to be more detailed. Under normal circumstances, it is suitable to sow seeds in the greenhouse at the beginning of February or in the open field at the beginning of April. The culture soil is suitable for agricultural fertilizer and garden soil, mixed with a small amount of rotten leaf soil, mixed evenly and sifted. Put the culture soil into a suitable container, gently compact the matrix, and then pour through the water. after the water seeps in, the seeds can be spread evenly on the wet soil. Pay attention to the depth of soil cover should not be too thick, in order to be able to cover the seeds. After that, keep the basin soil moist. The seedlings will emerge in about 10 days. When the seedlings grow 2 pairs of true leaves, they can divide the seedlings. Note that the seeds of thistle are small, so the seedlings grow slowly.

2. Cutting propagation of thistle.

The advantage of cutting propagation is that it can promote the early formation and flowering of thistle plants, and it can be cut in other growing seasons except low temperature in winter, and the survival rate is relatively high. First of all, prepare the healthy mother plant, put it in the greenhouse in winter, select the sturdy branches of thistle in early spring, and retain 2-4 true leaves. The length of the branch is about 5-6 cm. The cut is located under the node and can be inserted as soon as it is cut. The depth of cuttage is about 1-1-2 of the length of cuttings. In the hot season, the cuttings need to be placed in a cool and ventilated place to prevent the damage caused by the high temperature sun. In general, it takes about 10 days to take root, and then the seedlings can be divided.
