Introduction of cornflower cultivation methods:
Seedling : Choose loose and fertile soil for bed, cover soil about 0.2 cm, cultivation: when the seedling leaves are sent to 6-7 pieces, the potted plants are planted every 13-17 cm. After the seedlings are planted, they will be topped once, which will promote multi-branches and more flowering. If there are too many branches, if necessary, some lateral buds should be removed to obtain larger flowers. Because of the straight root nature, it is advisable to broadcast the autumn broadcast in the open field to cover the winter, and bloom in the early summer. If the cold bed winters, it can bloom in the late spring, and the spring sowing should be planted as early as possible. Flowering in June.
Cultivating place : Because cornflowers are native to European fields, they are slightly cold-resistant, cool and sunny.
Use soil : prefer sandy loam with loose and fertile and good drainage. The cultivated soil should be drained and well ventilated as much as possible. If the soil is heavy, it can be mixed with 3-4% of snakedust or pearlite for improvement.
Watering : Watering is sufficient once a day, but when it is dry in summer, it can be poured once in the morning and evening to keep the soil moist and reduce the temperature of the pot, but avoid water.
Fertilization : Cornflower is more fat, and the three-factor dilution should be applied once a month during the birth period. If the leaves are too luxuriant, the proportion of nitrogen fertilizer should be reduced. Before the flowering, more phosphorus and potassium fertilizer should be applied to obtain a larger flower with beautiful colors.
Flowering period management : Cornflower can naturally emit side branches, and the lateral branches are more small. If necessary, some side buds can be removed, and only small branches can be obtained to obtain larger flowers. Cornflowers are long-lived plants. In winter, the sunshine time is short. If you use plant lights to supplement the lighting at night, you can make flowering early.
