How to make hydrangea bloom during the Spring Festival

In order to make hydrangea bloom around the Spring Festival, it is impossible to let it regulate itself and artificial processing is required.

Selected plants

To ensure flowering during the Spring Festival, the plant must be strong and the branches must be neatly and evenly distributed. Make sure that the selected plants have completed flower bud differentiation. For example, a potted plant with a diameter of about 20 cm should have at least 4 to 6 branches. Such plants store a certain amount of nutrients themselves and will not wither in the winter temperature.

Repotting and changing soil

After the plant blooms from June to August, it is necessary to repot and change the soil in time. Make sure the soil is loose and rich in humus. Before potting, apply enough base fertilizer and prune the plants, leaving 1 to 2 nodes on each branch to reduce nutrient loss.

If you choose seedlings for cuttings, you must pinch the tops of the plants to avoid too many branches in winter and rapid loss of nutrients. During the pruning process, keep the branches with better growth to ensure a full and symmetrical plant shape.

Correct maintenance

To ensure that the plant has sufficient light, the light is strong from July to August, so the plant should be placed on a north-facing balcony and provided with appropriate shade.

Keep the soil moist but not waterlogged. Spray water appropriately to cool down when the temperature is high in August. If the plant is growing vigorously, you can control the water supply until the leaves wilt in the evening and then water it thoroughly. Repeating this several times can promote the plant's growth and help accumulate nutrients.

After new leaves grow, apply organic fertilizer once every 15 days. After autumn, the light intensity decreases. At this time, apply phosphorus and potassium fertilizers every 10 to 15 days until the flower bud differentiation is completed.

Adjust temperature

Flower bud differentiation is completed in late September, and careful maintenance is required in October. Remove the old leaves of the plant, place it in a cold room, control the temperature at 10℃, and reduce watering. After 40 to 60 days, which is mid-to-late November, move the plants out of the cold room.

Place the plants in a greenhouse, raise the temperature to 20°C, and maintain sufficient water and air humidity. After new leaves grow, apply organic fertilizer once every 7 to 10 days. Apply phosphorus and potassium fertilizers 2 to 3 times after buds appear. It will bloom in 50 to 60 days.

By calculating the time well, you can control flowering by adjusting the temperature. Lowering the temperature will delay it, while raising it will advance it. Make sure the temperature is controlled between 10~28℃ and there will be absolutely no problem with flowering!
