2. Shaping: Chou-heung and Michelia should be trimmed and shaped when changing soil, and old roots, rotten roots and insect roots should be cut off, and dead branches, overlapping branches, insect branches, leaves and tall branches of piles should be cut off. Generally, the height of the seedlings is 40 cm, and the width is appropriate. It is necessary to cut them into rings and sprout new buds, so that the flowers look good.
Third, fertilization: the principle of fertilization is to apply less and eat more. When changing the soil, put the multi-element flower fertilizer into the basin. Fertilization should be combined with root fertilization and topdressing outside the root. Top dressing outside the root can spray flower nutrient solution once a week, and then apply root fertilizer once a month.
4. Pest control: prevention is more important than treatment. Pesticides should be sprayed immediately after soil replacement, mixed with omethoate, dichlorvos emulsion and flower nutrient solution in equal amount, and then sprayed with 500 times of water once every half month.
5. Water: After Chou-heung and Smiling change the soil, water should be poured until the water flows out of the hole at the bottom of the basin, and then water it when the soil is dry.
6. Lighting: In order to make Chou-heung and Michelia blossom all year round, there should be proper lighting, that is, the flowerpot should be placed in a sunny and ventilated place.
Seven, flowering control: Chou-heung and Michelia will grow new leaves one month after changing the soil, and flower buds will grow two and a half months later. Attention should be paid to controlling the water content in the growth of flower buds, and not to have too much water, so that flower buds can grow and bloom. When the flowers are in full bloom, the water absorption will increase, thus promoting large flowers, dark leaves, more flowers and fragrant flowers. Don't spray water on the flowers during flowering to prevent them from falling early and withering.
