cultivation techniques

sowing season

The seeds of hollyhock can be sown when they mature in August and September, and bloom in the next year; Sowing in spring is not easy to blossom that year. Emerge 7 days after sowing, and be slightly covered with cold protection in winter.

According to the number of seeds of hollyhock, you can sow them on the seedbed in the open field and then transplant them, or you can plant them directly in the open field without transplanting. Autumn sowing is mostly used in the south, and it is usually advisable to sow in the open seedbed in September and germinate neatly. Spring sowing is the main method in the north. The seeds of hollyhock can be sown when they are mature, and normally the seeds can germinate in about 7 days. The germination ability of Abelmoschus manihot seeds can last for 4 years, but the seedling growth will decrease after 2~3 years of sowing. Direct seeding in the open field, if properly combined with transplanting in rainy days, can not only interplant seedlings, but also benefit from planting flowers for many years at a time.

The division of hollyhock is carried out in autumn. The clustered roots of perennial hollyhock are dug out in time, cut into several small clusters with a sharp knife, so that each cluster has two or three buds, and then planted separately. Strengthen water management slightly in spring.

Cut flowers can be cut in winter. The lateral branches germinated at the base of the old stem of hollyhock were used as cuttings, which were about 8 cm long and could be inserted into dry sand beds or pots. After insertion, cover it with plastic film and keep it moist, and place it in a cool place until it takes root. Before and after winter, electric heating wires should be laid under the bed to increase the ground temperature and accelerate the formation of new roots.

Soil requirements

Abelmoschus manihot likes cool climate, avoids summer frost, likes light, and is slightly resistant to shade; Suitable for deep, fertile and well-drained soil.

Potting technique

Water hollyhock in time after planting, and combine intertillage weeding and topdressing 1-2 times before flowering. Plants are generally renewed once every four years.

The cultivation and management of hollyhock is relatively simple. When the seedlings grow two or three real leaves, they should be transplanted once to increase the row spacing. Water in time after transplanting, cooperate with intertillage weeding topdressing 1 ~ 2 times before flowering, and topdressing Trim phosphorus and potassium fertilizer is better. Seeding seedlings can be planted in June 11after transplanting1times.

In the seedling growth period, liquid fertilizer is applied 2-3 times, mainly nitrogen fertilizer. At the same time, it is beneficial to plant growth and health to loosen soil and weed frequently. When buds are formed in the axils of hollyhock leaves, topdressing 1 times of phosphorus and potassium fertilizer. In order to prolong the flowering period, we should keep enough water. After flowering, the aboveground parts are cut off in time to sprout new buds.

Potting should be done in early spring, leaving only one flower. Because the seeds of hollyhock are easy to scatter when they are ripe, they should be harvested in time. After planting for 3-4 years, plants are prone to aging and should be updated in time.

In addition, hollyhock is easy to cross. In order to keep the purity of varieties, different varieties should keep a certain distance.
