Now the temperature has gradually risen, the daytime temperature in most areas can reach more than ten degrees, those dormant flowers and grasses have begun to show new shoots, in the field some small wild grasses have drilled out of the ground, everywhere a vibrant and thriving scene.
Today we are talking about the dormant hydrangea in winter, and the hydrangea is a relatively frost-resistant net red flower. In recent years, more and more friends like hydrangea flowers, hydrangeas bloom, flowers into clusters, dense and full, some are even larger than the face, one after another big flower balls are purple and red, well raised, even larger than the head, flowers into clusters, competing for glory, it is beautiful.
Raise hydrangeas in the spring, be sure to do these things well. The flower buds in the later stage are particularly large, the flowering cycle is neat, the flowering period is long, if it is not done well, the hydrangeas we raise will be much smaller. How to make the hydrangeas bloom big and colorful, and the flowering period is long? In the spring, we must do a good job in the maintenance of these steps.
First, bask in the sun in the spring
The leaves of the hydrangea are relatively large, and relatively thin, it is more afraid of exposure, so many people raise hydrangeas, and do not dare to put it in a well-lit place, in the summer must be shaded in the semi-shade or shaded under the tree is the best way to raise hydrangeas.
However, in the spring, when the temperature has just begun to rise, when the first warmth is cold, most of the leaves are falling light, and the light is relatively sufficient, which is also a good time for hydrangeas to grow. At this time, basking in the sun will not sunburn its leaves at a relatively low temperature, and the light is not so intense.
In the original environment, the tree does not have long leaves in the spring, and the light is directly able to be dried on the hydrangeas, so this is also in line with its growth law and is conducive to its budding. In winter, if it has been placed in a dark place, the cured hydrangea should be appropriately and gradually increased in light, and the new shoots will grow more oily green, so as to prevent the sudden reception of light and cause sunburn hydrangeas.
Second, water and fertilizer must be sufficient
In the winter, the hydrangeas are dormant, stop growing, and the root system does not absorb nutrients and water, relying on the nutrients it desperately needs. Spring temperature rises, hydrangeas begin to sprout and grow, at this time water and fertilizer is indispensable, the lack of water fertilizer leaves will appear scorched edge dry situation.
Affecting the growth of the whole plant and the flower buds, some flower buds will also appear deformed and appear to be absent or the flower head will become smaller. Hydrangea is more water-loving because of its large number of leaves, and the flowers are large, and water is not lacking for a day. When the surface of the potting soil is dry, it should be watered in time to ensure its smooth and normal growth. In general, the surface of the soil is dried or dried for a centimeter or two, and then watered it thoroughly, which is the best way to maintain it.
So what kind of fertilizer does hydrangea need to be applied? In the spring, the temperature has just begun to rise, be sure to add fertilizer to the hydrangea ball, you can add some multi-element fertilizer to it, such as huaduo no. 1, general-purpose compound fertilizer or organic fertilizer and so on. In order to help the growth of its entire plant, when it is about to sprout buds, it is given potassium dihydrogen phosphate or flower duoduo number two, so that it can push the buds out, both to grow leaves and flowers.
If you want to make the hydrangea blue, you have to work hard at the beginning of the bud, you can sprinkle some bluening agent in the soil, you can also use aluminum sulfate or ferrous sulfate. The main thing is to adjust the soil to acidic soil acidity, it can absorb more free aluminum ions, which helps the color of the hydrangea ball.
Generally, the bluening agent that is watered two to three times a month can ensure the acidity of the soil, and it can ensure that the flowers it produces in the later period are the color of blue Yingying. Of course, some people do not tune the blues thoroughly, it is easy to grow red through the blue through the red and colorful look, the tune is not complete, a little mottled, so if you raise a hydrangea tree, it is possible to adjust into a colorful small garden, it is also very interesting.
Third, the buds should be appropriately smeared
The germination rate of the hydrangea in the spring is very large, and each of its branches is very long. Every bud point under it sprouts and then grows straight out. In the spring, every bud point will be full of vitality and exuberance. However, if the branches of your hydrangea are particularly long, if there are too many long bud points, it is not conducive to the growth of the later stage, and it is also easy to appear that the flower head of the late flower is too large and there is a situation of lodging.
So at this time, the old branches on each bud can retain two or three branches that can flower, and the rest can be erased, and it is best to wipe off the crossed branches and weak branches of the whole pot appropriately, so that its entire plant type is more compact, the light is more uniform, and the flowering is also very full and round in the later growth.
When smearing the buds of the hydrangeas, pay attention to the buds at the bottom to properly remove a few inward growth, but the top buds are retained as much as possible, and the top is the largest and most well-rounded bud of the flower, so that most of the buds are erased, only a small number of flower buds are retained, the nutrients it can concentrate on supply, the branches it grows are more stout, more weekly, the flowering will be larger and more colorful, and the flowering will be long.
After the buds are smeared, proper fertilization and lighting are required, so that the hydrangeas will bloom large and colorful, and the flowers will be neat. If it is a potted hydrangea as far as possible outdoors, proper reception of light and fertilization can also erase some of the fresh buds to ensure its own nutrients, so that the hydrangeas will be large in the spring, and the plants will bloom neatly and beautifully.
