For camellias, loose soil is very helpful for plant growth.If it is planted in the ground, it should be planted in sandy loam with good drainage and certain water retention.If it is a potted plant, you can prepare your own potting soil, generally mixed with mountain soil, sawdust and cake fertilizer powder, the ratio of the three is 5:4:1.The prepared soil needs to be bagged and matured, which usually takes 20-30 days.
Camellia is a semi-shade flower, itself is a long-day plant, so it needs to ensure adequate light, but it is afraid of strong light.During the growth period, it should be placed in a semi-shade environment so as not to burn its leaves under strong light.When the plants enter the flower bud differentiation period in autumn, the daily illumination time should not be less than 12 hours, otherwise the formation of flower buds will be affected.In winter, they should also be placed indoors in sunny places, if the light is weak, the plants will grow poorly.
Camellias prefer to be wet, and are suitable for growing in acidic environment, so alkaline water can not be directly irrigated, and ferrous sulfate needs to be added for acidification before it can be used by plants.If it is tap water, it needs to be placed for two days first, waiting for chlorine to volatilize before pouring.The amount of water should not be too large, otherwise it will lead to plant root rot.If the environment is dry, it is also necessary to spray water on the leaves to humidify them.
Camellias need to be fertilized with sufficient base fertilizer when planting to provide nutrients for them continuously.During the sprouting period in spring, thin fertilizer water should be applied every half month, and phosphorus and potassium fertilizers should be supplemented in summer.In autumn and winter, due to the rapid growth of flower buds, decomposed liquid fertilizer should be applied once a week, and phosphorus and potassium fertilizers should be applied 1-2 times, nitrogen fertilizer should not be too much, otherwise it will lead to bud withering.
