In the process of Helleborus cultivation, it is best to use a mixture of sandy soil, leaf rot soil, sawdust and decayed organic fertilizer to make culture soil. During the growth and development, the plants should be placed in the semi-shade. In autumn and winter, the plants should be exposed to more sunlight, and the principle of drying and wet watering should be maintained.
Helleborus has a high requirement on the soil, in the sandy soil moist fertile and rich in nutrients to grow more appropriately, mainly composed of micro alkaline soil. We can choose wood shavings, rotten leaves of organic fertilizer, sand, and mixed stirring, after changing basins in the late spring or autumn, which is good for the growth of the root system.
Helleborus want to grow in sunny and warm environment, cold resistance is very strong, mainly accept astigmatism during growth and development, during the spring and summer when you need to put half overcast environment of plant maintenance, qiu dong season all can let the plant under the sun more sun, but must carry on the spray cooling process at high temperature in summer, so as to avoid sunburn.
Water and fertilizer management is one of the cultivation methods and matters needing attention for Helleborus. When potted Helleborus, it is advisable to keep the pot soil moist frequently, but no water should be accumulated. Water should be kept dry and wet, and the amount of water should be reduced in cool weather, and the soil should be loose after watering.
During the growth period, Helleborus can often see aphids or black spots and other harm. After the onset, there will be many spots on the leaves, which will gradually become black and wither. It is better to pay attention to ventilation in the early stage, and spray diluted soap solution or oxidized dimethoate solution once a week until the improvement.
The root system of Helleborus grows fast, so it is best to change the pot at the end of spring every year. After all the dead branches and diseased and insect branches are cut off, the rotten roots and dead roots above should be cut off, and some bone powder should be put in the bottom of the pot, and then replanted for curing, so as to promote the healthy growth of the root system.
