What are the key points of high-yield cultivation techniques for white magnolia?

Watering White magnolia should not be watered too frequently or excessively. The correct watering method should be: moisten the soil in the pot thoroughly in one go, and when the soil in the pot is slightly dry, there is no need to water. Remember not to water every day, but you can frequently spray water on the leaves with a small spray bottle. Fertilizing During the vigorous growth period of white magnolia (usually May or June, or July or August each year), apply a flower fertilizer to white magnolia about once every half a month, or apply a small amount of nitrogen, phosphorus, and potassium compound fertilizer at around 20, 2 grams to 6 grams each time. Pest and disease control White magnolia prefers acidic soil. If the soil is alkaline, or the irrigation water is also alkaline, it can easily cause yellowing of white magnolia leaves and blackening and rotting of the root system, known as chlorosis. A 0.2% ferrous sulfate aqueous solution can be sprayed on the leaf surface, once every 5-7 days. A 0.5% ferrous sulfate aqueous solution can also be applied frequently for prevention and control.
