How are seeds planted?

Hollyhock is a biennial erect herb of the genus Hollyhock of Malvaceae. It is usually propagated by sowing and can also be propagated by ramet and cutting. Ramet propagation is carried out in spring, and the cutting method is only used to propagate some fine varieties. Most of the production is sowing and reproduction, and spring sowing is the main method in North China. Let's take a look at how to plant hollyhock seeds.

Growth habits of hollyhock

Hollyhock is widely distributed in China, including East China, Central China, North China and South China, and is widely cultivated all over the world. Like plenty of sunshine, withstand half-overcast, but avoid waterlogging. It has strong saline-alkali tolerance and can still grow in soil containing 0.6% salt. It is resistant to cold and can survive the winter safely in the open field in North China. It grows well in loose and fertile sandy soil with good drainage and rich in organic matter.

How to plant hollyhock seeds?

Hollyhock can be sowed in spring or autumn, according to the number of seeds, can be sowed in the open field seedbed, and then seedling transplanting, can also be open field direct seeding, no longer transplanting. Autumn sowing is often used in the south, and it is usually appropriate to sow in the open field seedbed in September and sprout neatly. In the north, spring sowing is often the main method. Hollyhock seeds can be sown after maturity, and normally they can germinate in about 7 days. The germination ability of hollyhock seeds can be maintained for 4 years, but the growth decline occurs after sowing seedlings for 2 or 3 years. Direct sowing in the open field, if properly combined with transplanting in overcast and rainy days, can not only interplant seedlings, but also benefit from planting flowers for many years.

Planting method of hollyhock

1. Watering: when 2 or 3 true leaves grow out of hollyhock seedlings, they should be transplanted once, the row spacing should be enlarged, and should be watered at the right time after transplanting. The flowering period should be properly watered to promote a long flowering period and a good flowering all the way to the top of the stem.

2. Fertilization: during the growing period of hollyhock seedlings, attention should be paid to fertilization, removing and loosening the soil in order to make the plant grow healthily. After the flower bud is formed in the leaf axil, it is necessary to apply phosphorus and potassium fertilizer, and cut off a few pieces of the leaves at the base.

3. Root cutting: when planting hollyhocks, in order to make the plant low and prevent lodging, the roots can be cut off under the conical shape of Juglans mandshurica around the plant in June, once every 2 to 3 weeks, and then watered immediately.

4. Harvest: when the hollyhock fruit is yellow and ripe, it should be harvested immediately to avoid scattered seeds. After the end of flowering, the aboveground parts of the plant can be cut off and new buds can be sprouted to form tufted plants. Hollyhock is easy to senescence and should be renewed after 2-3 years of cultivation.

How to sow hollyhock seeds

Sowing season

The sowing of hollyhock seeds is very simple, and there is no need to pay special attention to the sowing season. Hollyhock seeds can be sown between August and September, and if sown at this time, they can blossom the following year.

Sow seeds

After the seeds are ripe, choose a piece of fertile, breathable land (or prepare some nutritious soil), plant the seeds evenly, and cover them with a small amount of soil. Remember to water the seeds for the first time.

Maintenance

The steps of maintenance include watering, fertilizing and root cutting.

Watering

In addition to watering enough when sowing for the first time, it should also be properly watered when hollyhocks bloom to improve the normal and healthy growth of hollyhocks.

Fertilizer application

All plant conservation is inseparable from fertilization, it should be noted that the period of fertilization is the seedling growth period of hollyhock, when the root development of hollyhock is not complete, can not normally absorb nutrients from the earth, at this time appropriate fertilization can improve the survival rate of hollyhock.

Cut the root

The result of cutting off roots is that hollyhocks will be relatively short, so don't get into the misunderstanding that being low is not a good plant, because hollyhocks themselves are relatively tall, and when they are too tall, they will lodge. So the purpose of cutting roots is to prevent hollyhocks from lodging. Around June, the roots are cut off in a conical shape around the hollyhock, usually once every two or three weeks.

Sowing method of hollyhock seed, sowing time in spring and autumn

The seed sowing method of hollyhock is the most commonly used way of reproduction, hollyhock sowing is generally better in spring and autumn, the following arrangement of hollyhock seed sowing method.

Sowing method of hollyhock seed 1. Sowing time

Generally speaking, the sowing time of hollyhock can be carried out in both spring and autumn. It is suggested that autumn sowing is better in the south and spring sowing in the north.

2. Soil preparation for sowing

The basin soil sown with hollyhock can use 80% pond mud and 20% peat soil. Of course, if you don't want to be simpler, you can also use 100% pond mud.

3. Sowing method

Sow the ripe seeds of hollyhock on the prepared soil, remember to spread them evenly, not in one place. After the seeds are evenly sown, remember to spread a thin layer of soil on the surface of the seeds, remember to pour enough water, and then cover them with a lid.

Just put it in a ventilated place. Generally, it can sprout in about a week after sowing. When the hollyhock seedlings have 2-3 true leaves, they can be transplanted, and generally they can blossom the following year.
