The requirement of brocade flower to soil is not strict, can bear barren soil, but afraid of water logging, so we should choose sandy loam with good drainage. The soil is required to be deep, moist and rich in humus, which is most suitable for the growth of broccoli.
Broccoli likes fertile soil. When potted, it can be mixed with garden soil and rice husk ash, and a small amount of base fertilizer can be applied. In the growing season, broccoli should be fertilized 1-2 times a month. The fertilizer can be liquid fertilizer. In the dormancy period of winter or early spring, the root should be furrowed and fertilized every two to three years.
The suitable temperature for the growth of broccoli is 15-35 degrees, and the suitable temperature for the flowering period is 18-22 degrees. Cold resistant, northern areas can also be exposed to the winter, can be in the Lee to the sun.
Attention should be paid to watering during the growing season of brocade flowers. When growing again in spring, the amount of watering should be increased gradually to keep the basin soil moist. In summer, when the temperature is high, it can be properly watered to maintain sufficient water and spray water to cool down. As broccoli is afraid of water logging, we should pay attention to flood prevention in the rainy season. One or two times of water permeability shall be poured every month to meet the growth demand.
The propagation methods of broccoli include sowing propagation, cutting propagation, layering propagation, and splitting.
There are not many diseases and insect pests of broccoli, and occasionally there are aphids and spiders, which can be killed by dimethoate spray.
Broccoli is sensitive to spring drought and cold, and is easy to dry. Therefore, it is necessary to cut off the dry branches before flowering, and cut off the branches in time after flowering to promote the growth of branches. The old branch has a short life and needs to be re cut and renewed from the base.
