How to plant hollyhock seeds?

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. [4] production is dominated by sowing and reproduction, and spring sowing is dominant in North China. Let's take a look at how hollyhock seeds are planted.

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.
