There are five things you need to do to make hydrangea blossom year after year.

In places where there is not enough light at home, you can also raise hydrangeas. It does not need too much light, and can grow in half-shade. As long as you give a little scattered light every day, you can produce beautiful flowers and blossom every spring. But here are five things you need to do well.

Hydrangea is a kind of flowering shrub plant that I like very much. Some friends think that hydrangea needs a lot of conservation and is very picky about the environment, but this is not the case. Hydrangea is easier to grow than you think. It's easier to blossom. Have you done all the following five points?

The first point is the location of planting

Plant different types of hydrangea, you have to choose the right place, some varieties are a little more light, some are slightly shade-resistant.

Planting location is best east-facing balcony or courtyard, can give more light in the morning, noon and afternoon to shade, such an environment to grow best.

In addition, the growth of hydrangea needs a larger space, each hydrangea should have appropriate spacing, do not plant too dense, generally cultivated in the spring and autumn season. Before planting hydrangea, we should dig holes properly, prepare loose and drained soil, and add some compost at the bottom. Hydrangea prefers water, and the soil should have a certain water retention capacity.

Second, pay attention to watering and fertilizing.

Hydrangea prefers water and should be watered regularly during the growing period to avoid excessive drought in the soil, otherwise the leaves are easy to wilt.

Hydrangea in the growing period is to keep the soil moist, the cultivation of hydrangea is to give appropriate fertilizer, so as to promote the growth of hydrangea.

Usually, you can give thin fertilizer once every 1 to 2 months, you can use average fertilizer, and when the early growth is not so exuberant, you can give nitrogen, phosphorus and potassium 12:4:8 compound fertilizer. After the vigorous growth of stems and leaves in the later stage, potassium dihydrogen phosphate can be properly supplemented to promote flowering.

Third, pay attention to the pruning of hydrangea.

Once you find withered flowers or are ready to wither, you must cut them off in time to avoid consuming too many nutrients, and so the hydrangea branches begin to grow old, gradually Lignification will produce smaller flowers, but also to be pruned regularly.

After the branches of hydrangea grow too high, it is necessary to pinch the top properly to avoid the hydrangea growing too high, and you can choose to prune it properly in autumn or after flowering.

Fourth, the growth rate.

Hydrangea can grow to about 50 to 60 centimeters every year, growing very rapidly, and requires a larger space for cultivation. Pot maintenance must choose a larger container, drainage should be guaranteed, and the bottom can be covered with some granular stones to avoid blockage of drainage holes.

Fifth, change the color of hydrangea.

Hydrangea can produce very unique flowers, flowers look like charming colored hydrangeas, and you can also control the color of flowers, that is, changing the pH value of the soil to make hydrangeas change color, the stronger the alkalinity of the soil, the flowers will turn pink. If you want pink hydrangeas to become blue, you can increase the acidity of the soil, which can make its flowers blue.

Add some peat soil or compost soil regularly to make the soil slightly acidic, or you can pour some ferrous sulfate solution directly. If you want to make the soil alkaline, give lime regularly.
