Hydrangea is a great ornamental flower, they have huge spherical flowers, they look like a big hydrangea, rich in colors, there are common blue, pink, white and green, and brilliant flowers can be seen throughout spring and summer.

Maintenance hydrangea can not be raised in the place of excessive exposure, can be raised in the shade of trees, every day with appropriate scattered light can grow well.

Some flower friends buy hydrangea flowers that grow very well in the first year, but they can no longer blossom after the second year. Here are the reasons why they do not blossom and the solutions.

1. Soil selection

The cultivated soil has a great influence on hydrangea, and we can also make hydrangea bloom into different flowers by changing the acidity and basicity of the soil.

If your soil can not blossom, it is not because the soil is alkaline, but probably because the soil is lack of fertility, and some soil is due to too much nitrogen fertilizer, which leads to hydrangea can not blossom only with leaves. It is necessary to replenish phosphorus and potassium fertilizer in order to produce brilliant flowers.

You can add some rotten sawdust or compost soil directly to the soil, or you can add peat soil, which can improve the soil fertility. If you think it is too troublesome, you can directly pour some potassium dihydrogen phosphate solution.

2. Replenish fertilizers appropriately

Hydrangea will consume a lot of energy to promote the growth of leaves. If you want hydrangea to blossom every year, you need to replenish fertilizer in time, so as to promote flowering. In the process of maintenance, you can properly supplement fertilizer after the flowers have withered. In the growing season of hydrangea, you can regularly supplement potassium dihydrogen phosphate, or supplement potassium dihydrogen phosphate or other fertilizers with high phosphorus and potassium fertilizer once a month or two months.

3. Newly planted hydrangea

Some friends just planted hydrangea can not germinate normally in the first year and the second year. Hydrangea needs a lot of energy to promote root growth, which can ensure the growth of hydrangea plants. So maintain hydrangea in addition to regular fertilizer supplements, but also maintain enough patience to help continue to bloom in the second year.

4. Incorrect pruning

Whether potted or ground-cultivated hydrangea flowers do not need pruning, some friends do not know how to maintain hydrangea flowers, random pruning, it is easy to cause fungal infection, if there are diseased branches and leaves should be cut off as soon as possible, other branches and leaves should be preserved.

Hydrangea generally only needs to cut off the residual flowers in time after flowering. Withering the flowers and removing the residual flowers will help to retain more nutrients and promote continuous flowering.

There are different types of hydrangea, which are conducive to maintaining good growth, some varieties with strong and tall plants, some varieties that grow and blossom on new branches and leaves, and others are divided into endless summer series of hydrangeas.

Hydrangeas are usually properly pruned in late winter or early spring, and it is best not to prune them after the warmth of spring, otherwise it is easy to cut off the new branches that give birth to flowers.

5. Pay attention to maintenance in winter

Hydrangea is easy to be infected by the cold wind when the weather is cold. It is necessary to keep warm in winter, and of course, do not put it in the greenhouse, otherwise the temperature is too high, it will affect the hydrangea dormancy and eventually affect the flowering.

When the winter temperature is too low, you can cover the bottom of the rhizome with some felt, or you can cover some peat soil or rotten sawdust.

6. It is not suitable to maintain the environment.

Maintenance hydrangea can not be raised in a completely shaded place, excessive shading will cause hydrangea can not blossom, maintenance hydrangea position can have appropriate scattered light every day, the media to maintain about 4 to 8 hours of scattered light is enough, but also to avoid raising in the position of excessive light, otherwise easy to cause leaf sunburn, serious also easy to cause plant wilt.

Maintenance of hydrangea also requires regular watering, and a lot of water is needed during the growing period, especially in the first year or two of planting, do not let the soil of hydrangea be completely dry, increase the watering frequency after high summer temperature, and keep the soil slightly moist, but avoid stagnant water in the soil.

In addition, you also need to choose a variety of hydrangea suitable for your local growth. if you raise a variety of hydrangea, the maintenance method is very correct, but it still grows poorly, or cannot blossom, probably because the variety is not suitable for local growth.
