White magnolia is an evergreen tree that prefers warm and humid conditions, does not tolerate cold or drought, and its flowers emit a fragrant aroma with a pure white color.
The key to making potted white magnolia have large flowers, more blooms, fragrant scent, vibrant color, and a long blooming period is to strengthen the management during the flowering period.
1. Provide Suitable Light
White magnolia is a sun-loving flower that requires plenty of sunlight. During the growing period, it should be placed on a sunny balcony or in a sunny area to care for, especially during the flowering period. Daily sunlight should not be less than 6 hours.
If white magnolia is cared for in a shaded area, it will only grow leaves without flowering, or bloom very few flowers, with thin and long branches, pale leaf color, thin leaves, and no luster, which is very unfavorable for its growth.
However, during the hot and high-temperature "dog days" of summer, it is necessary to provide moderate shading, avoiding direct sunlight from 12 to 4 pm and also avoiding the high-temperature radiation from brick walls or concrete ground.
During this time, not only should water be sprayed on the plant to cool down, but also water should be poured or sprayed on the ground to dissipate heat, increase humidity, and artificially create a suitable environment.
2. Watering in a Timely Manner
White magnolia has a succulent root system that needs water but fears waterlogging.
Therefore, water once a day from early summer to late autumn to keep the soil moist. However, during the hot "dog days" of summer, water in the morning and evening, and also spray water on the leaves and the ground around the pot to increase humidity.
When using tap water to water white magnolia, be careful to prevent soil alkalization. If the leaves turn yellow, apply sulfuric acid iron water or use 0.7% to 0.8% vinegar water to water the roots. You can also spray 0.3% to 0.4% vinegar solution on the leaves, which also works well. During the rainy season in spring, avoid waterlogging in the pot, as it can cause root rot.
3. Supplement Adequate Nutrients
This is an important part of flowering period management. White magnolia is a flower that loves fertilizer because it has a long flowering period and many blooms. Therefore, timely and regular nutrient supplementation is necessary to achieve more flowers, larger blooms, vibrant color, and fragrant scent.
In addition to applying enough base fertilizer when potting, it is necessary to apply a phosphorus and potassium-based organic liquid fertilizer every 5 to 7 days during the flowering period from May to October, such as decomposed cake fertilizer water. The principle of fertilization is to apply thin fertilizer frequently, or start with a lighter solution and then a stronger one. Never apply raw fertilizer, as it can burn the roots. Also, apply foliar feeding every 7 to 10 days using 0.5% plant growth hormone and 0.3% monopotassium phosphate solution.
4. Prune Leaves and Pinch Shoots
The time to move white magnolia outdoors is between the vernal equinox and Qingming Festival every year. Choose a cloudy or overcast day to move it outdoors and let the potted flowers adapt to the outdoor environment for 2 to 3 days before starting to remove old leaves, leaving only a few tender leaves on the branches to promote new growth.
After each batch of flowers has finished blooming, remove a few old leaves to promote new branch growth and bud formation. During the growth period of white magnolia, it is also necessary to pinch the tips to control apical dominance and promote the growth of lateral branches.
5. Prevent and Control Diseases and Pests
The main pests of white magnolia are aphids and scale insects.
Scale insects can be controlled by spraying 0.3% to 0.4% vinegar solution or removing them by hand.
Aphids damage the buds and flower buds. You can use a rapid insecticide to kill them, or spray a 500-fold solution of laundry detergent, or use a cotton swab soaked in laundry detergent solution to stick and remove the pests, then rinse the branches and leaves with clean water.
In the process of managing white magnolia, it is important to prevent and control yellowing disease and root rot, as well as anthracnose disease.
If diseases are found, promptly remove the diseased plants and leaves, and spray 50% carbendazim 500 to 800 times liquid solution on the leaves, or use 70% thiophanate-methyl 800 to 1000 times solution for control.
