Tools: humus soil, river soil and sand, garden soil, water, fertilizer, insecticide emulsion, etc.

1, suitable soil. Hydrangea likes to grow in loose, breathable and slightly acidic soil rich in humus. It is suggested to use humus soil, river soil sand and garden soil to raise hydrangea. When mixing soil, in order to ensure the growth of hydrangea, it is necessary to disinfect the soil and add an appropriate amount of organic fertilizer.

2. transplant and shape. After transplanting, it is necessary to shade properly and spray water on the leaves to facilitate seedling delay. When new leaves grow, we should remove the dense branches and overlapping branches in time, leaving 3 ~ 5 branches to obtain good plant shape.

3. Suitable temperature and light. Hydrangea likes warm environment, and the optimum temperature for its growth is between 20℃ and 25℃. Hydrangea likes light, so it is recommended to keep it on the balcony or window at home. Adequate illumination is beneficial to plant growth and flower bud differentiation. However, due to the strong seasonal light, in order not to be burned by strong light, corresponding cooling measures must be taken.

4. Pruning of branches. After flowering in September, branches should be cut short quickly to prevent nutrient loss and promote the growth of new branches. After the new branch grows, the bud center should be removed from the new branch immediately, so as to provide nutrients for the new branch and promote the growth of the new branch next spring.

5. Rational fertilization. The growth of hydrangea is inseparable from reasonable watering and fertilization. Water the plants 2-3 times a week during the growing period, and add 1 times diluent fertilizer every 20 days to ensure the growth of the plants. Apply phosphorus and potassium fertilizer once before flowering to promote and protect flowers.
