What are the precautions for planting white magnolia?

White magnolia is a common flower in daily life. It gets its name because its fragrance resembles that of an orchid and its flowers are pure white and as auspicious as desired. It can bloom continuously all year round and is loved by many flower enthusiasts. So what are the precautions for planting white magnolia?

1. What are the precautions for planting white magnolia?

1. Afraid of alkaline soil

White magnolia prefers acidic soil, with a soil pH requirement of 5.5-6.3. If the soil is on the alkaline side, it will dissolve the protoplasm of its cells, causing slow flower development and poor growth. Watering with fermented rice-washing water can be effective.

2. Water must be appropriate

White magnolia has fleshy roots. When the soil becomes waterlogged, its leaves will turn yellow and drop, and the roots may even rot and the plant may die. When the soil is too dry, the leaf tips will wither and the leaves will curl. It is a flower that fears both waterlogging and drought, so watering must be done with care.

3. Afraid of concentrated fertilizer

White magnolia prefers phosphorus and potassium fertilizers, but it should not be given fertilizer that is too concentrated, otherwise reverse osmosis will occur and cause physiological drought. In mild cases it will wilt, and in severe cases it will be burned to death. Its fertilization principle is to apply diluted fertilizer, apply it often, and apply it in the evening.

4. Choose two-year-old branches as rootstock for grafting

The grafting rootstock should be chosen from two-year-old branches. In the plum rain season, take branches of the same thickness as the rootstock. After grafting is completed, it will heal in about 60-70 days, and then it can be cut away from the mother plant.

2. What are the cultivation methods for white magnolia?

1. Soil

White magnolia is suitable for growing in deep slightly acidic or neutral soil. It prefers fertile, appropriately moist, well-drained weakly acidic soil and is not tolerant of saline-alkaline soil.

2. Watering

The root system of white magnolia is fleshy and not tolerant of waterlogging. During the flowering and growth period, the soil should be kept moist. After autumn begins, watering should be reduced to delay root growth, promote branch maturity, and help it overwinter. In winter, generally do not water, and only water once when the soil is too dry.

3. Light and temperature

White magnolia is suitable for growing in an environment with ample sunlight. Sufficient light can make its branches luxuriant and its flowers more numerous and fragrant. If light is insufficient, it will develop poorly. White magnolia is also quite sensitive to temperature; too high a temperature will cause it to bloom early. It can endure a low temperature of minus 20 degrees for a short time, but when the temperature is below minus 20 degrees, cold protection measures must be taken.

4. Fertilizing

White magnolia likes fertilizer, but it should not be given heavy fertilizer. During the growing period, applying fertilizer twice is generally enough to promote its growth and flower bud differentiation. The fertilizer is mostly fully decomposed organic fertilizer. Newly planted seedlings may not need fertilizer; fertilize after leaf drop or in the following spring.

5. Pruning

White magnolia has relatively poor healing ability in its branches, so it is generally not stimulated. However, for a reasonable tree shape, overly vigorous branches, dead branches, diseased and pest-damaged branches, and other branches that hinder the beauty of the tree shape should be pruned.
