How to adjust the color of hydrangea, choose the right time to fertilize properly / the soil is blue and alkaline and red.

The beauty of hydrangea lies not only in its shape like that of hydrangea, but also in its rich colors. Flower friends who have raised hydrangea should know that hydrangea can be adjusted, and according to the acidity and basicity of the soil, it can be adjusted to various colors of red, blue and purple. As for how to adjust the color of hydrangea, I believe that the vast majority of flower friends do not know, in this regard, the editor will introduce you a method of color blending, which should not be missed.

Soil is the key to how to adjust the color of hydrangea.

Friends who know something about hydrangea should know that hydrangea flowering is "acid blue, alkali red". To put it simply: in acidic soil, hydrangea blossoms blue; in alkaline soil, hydrangea blossoms red. But should the acidity and alkalinity of the soil remain unchanged all the time, or should it be adjusted when it blossoms? How to adjust the color of hydrangea has become a problem that all growers want to know. In this regard, the editor will teach you the secret of hydrangea color blending!

(1) Hydrangea blossoms in red

If you want to have red flowers, how to adjust the color of hydrangea? In fact, it is very simple, we only need to keep the soil alkaline, hydrangea will bloom red flowers. Practice: we do not use acid soil, fertilizing when not applying acid fertilizer, it can bloom safflower. So in life, red hydrangea is very common, in the roadside green belt, a piece of red hydrangea, looks very beautiful!

(2) the method of blending hydrangea into blue and purple.

1. Prepare color-blending fertilizer

How to adjust the color of hydrangea? Apart from the soil, the most important thing is to apply fertilizer. If you want to adjust hydrangea to blue or purple, you need to prepare fertilizers that can adjust the pH of the soil, such as aluminum sulfate, white vinegar, ferrous sulfate, potash and so on.

2. Color blending method and time

① Hydrangea with pure blue flowers

If you want hydrangea to produce pure blue flowers, you need to pay attention to the time to adjust the acidity and alkalinity of the soil. In bud formation, aluminum sulfate fertilizer should be irrigated to the roots of hydrangea every 10 days to increase aluminum ions in the soil. The reason why the flowers turn blue: there is an anthocyanin in Hydrangea, which turns blue when combined with aluminum ions.

How to adjust the color of hydrangea? In addition to irrigating aluminum sulfate every 10 days, acidic water, such as ferrous sulfate and white vinegar, should also be watered during this period, in order to keep the hydrangea pot soil acidic for a long time. However, when applying fertilizer, we must pay attention to the concentration, especially at the beginning, the concentration must not be too high. It is found that the fertilizer is too much or too thick, and the root is irrigated with clean water.

② Hydrangea blossoms in blue, purple and pink

If you want hydrangea to produce blue-purple and pink flowers, you should also apply acid fertilizer, but the fertilization time needs to be delayed. After the hydrangea blossoms in pink, begin to irrigate the roots of the hydrangea with aluminum sulfate and vinegar, so that as the hydrangea continues to open, the color will gradually change to the complex color of blue and purple powder. If you continue to use acid fertilizer and water, the flowers may be pure blue.

③ Hydrangea blossoms blue and purple

How to adjust the color of hydrangea? If you want hydrangea to produce blue-purple flowers, stop applying acid fertilizer not only before bud formation, but also after bud coloration. After doing so, the acidity of the soil will gradually dilute with the cessation of acid fertilizer and become neutral or weakly alkaline, and the color of hydrangea will also change into a purple and bluish feeling.

Know all about hydrangea planting, maintenance and color blending!

I still remember when I saw hydrangea for the first time, I was surprised by smallpox. At that time, I didn't know it was hydrangea. The flower ball with a big head was full of the whole plant, and the color transition was just right, too beautiful to move. Born like a summer flower, I'm talking about a warm flower like hydrangea.

The following content comes from: Mr. beard is born like summer hydrangea with dignified appearance, varied colors, sometimes bright and sometimes beautiful, long ornamental florescence, and like semi-shady environment, and the balcony facing north can also be planted.

Last time we talked about how to distinguish hydrangea, friends have left messages on how to plant hydrangea? Today we will talk in detail about how to plant, maintain and bring out dream-colored hydrangeas.

The propagation methods of planting hydrangea include cutting, ramet, striping and so on, of which cutting is the main one. Because cuttings should pay attention to moisturizing, they are mostly cut in the rainy season.

Cutting steps

1. Cut the unsprouted healthy branches with full bud spots as cuttings, preferably semi-lignified branches to the touch.

two。 Cut cuttings to retain nodes, cut shorter above nodes, cut flat to retain buds, and cut diagonally at 5cm below; cut flat and not squeeze cuts; cut leaves in half to reduce transpiration and photosynthesis.

3. The matrix is well drained and fertile soil can be added with an appropriate amount of perlite to increase air permeability; the matrix can be sterilized with potassium permanganate or carbendazim before use; and should be watered thoroughly and fully watered before cutting.

4. When cutting, punch a hole with a stick, compact it by hand after insertion, and water and plant to ensure that there is no gap between the substrate and the cuttings.

5. Store in a shade, astigmatism, cool and ventilated place, you can put on a transparent plastic bag to moisturize; pay attention to check and spray moisturizing every day. If the leaves wither, it means less watering, and if the stalks become paste and black, you will water too much. Throw away the treatment in time to avoid infecting other cuttings.

Be careful

1. If you have rooting powder, you can add a little bit to improve the survival rate.

It takes about 2.1 months to take root and transplant, so don't fiddle with it from time to time.

Daily maintenance of Hydrangea Hydrangea likes shade, dampness, fat, and poor cold resistance, so to ensure that it blossoms in the coming year, you must take good care of it.

Light

In spring and autumn, hydrangea potted plants can be placed in a semi-shady environment; in midsummer, they can be moved to a well-ventilated shady place; in cold winter, they can be moved indoors.

Watering

Hydrangea leaves are larger and require more water, so it is necessary to water frequently to keep the soil moist, especially in the morning and evening in midsummer, but not too much, drainage in time in the rainy season, and slightly dry soil in winter to reduce watering.

Fertilizer application

Some friends have little or no flowering of hydrangea, probably because they do not have enough nutrition. During the growth of Hydrangea, cake fertilizer can be applied every 15 to 20 days, and 0.5% superphosphate soaking solution can be added for 1 to 2 times when the inflorescence is elongated.

Soil

The planting soil of hydrangea should choose a matrix rich in humus and good drainage, so it is convenient to buy general culture soil directly. Hydrangea can be changed and pruned every 1 ~ 2 years.

Pruning

The withered flowers should be pruned, the frostbitten branches should be trimmed, and the dead branches that are no longer growing can be cut but not cut; in addition, hydrangea generally does not need to be trimmed, otherwise the branches with long buds will be mistakenly cut, which will lead to no blossoms.

Flowerpot

It is recommended to choose some thicker pottery basin, cement basin, air permeability will be better.

Hydrangea color adjustment we often see a bunch of hydrangea pollen color, blue, purple is very good-looking, but also know the "acid blue alkali red" flowering law, but how to operate it?

In hydrangea, there is a kind of anthocyanin called "deltamethrin". When combined with aluminum ions, the flower color will be blue, but it can only absorb free aluminum ions. Most of our potted plants do not contain aluminum, so the flowers grown without color are mostly pink.

1. Pure blue flowers

If you want pure blue hydrangea, before the formation of hydrangea buds, aluminum sulfate can be irrigated every 10 days to increase aluminum ion content, in addition, appropriate amount of ferrous sulfate and white vinegar water can be applied to keep the soil acidic for a long time.

Fertilizer should pay attention to the concentration, if the Hydrangea leaves become soft means that the concentration is too high, timely irrigation of roots a lot of water.

two。 Turn it into blue-purple and pink flowers.

When you want to be multicolor, the fertilization time of acid fertilizer should be delayed appropriately, and after the hydrangea begins to blossom in pink, aluminum sulfate and vinegar will be applied. With the gradual change of soil acidity, hydrangea will also show a dreamy gradual tone.

3. Turn it into purple flowers

If you want hydrangea flower color to be purple, acid fertilizer should be applied before flower formation and stop after flower bud coloration. The acidity of soil will gradually decrease and show neutral or weak alkaline with the cessation of acid fertilizer, which means flower color will also appear blue-purple.

4. Turn it into pink flowers

If the soil itself is slightly acidic, if you want to bring out pink, the method is similar, but the acid fertilizer can be replaced with alkaline fertilizer, and the fertilizer can be used with plant ash.

Note:

1. Fertilization doesn't need to be applied all the year round, just add and stop it at the right time.

two。 Hydrangea varieties had better choose "endless summer", some hydrangea varieties do not have the ability to change color; 3. Each kind of fertilizer should be applied separately and cannot be mixed together.

4. The concentration of fertilization must be paid attention to, it is better to be light than thick, and if something goes wrong, it will be diluted with clear water.

5. Spraying phosphate fertilizer during the color blending period, root irrigation will prevent hydrangea from absorbing aluminum ions.

6. The final color must be adjusted in advance, once the pregnant bud can not adjust the color.

Warm reminder that hydrangea can not be eaten, accidental eating will appear abdominal pain, vomiting, weakness or sweating and other symptoms, especially families with children need to pay attention to!

What is hydrangea language? How to cultivate it?

Hydrangea, also known as "eight Immortals" and "Ziyang Flower", is a deciduous shrub of Saxifragaceae, originating in China, Japan and other regions.

The most important and basic knowledge of hydrangea planting is to pay attention to ventilation, poor ventilation can easily lead to Hydrangea root rot, resulting in the death of the whole plant. General family yard, and open balcony can be planted. You can't grow it indoors.

Pay attention to the light, Hydrangea belongs to shade-loving plants, but no light will lead to plant death, less light plants will not be good, appropriate light can promote the growth of Hydrangea. Take the Jiangsu and Zhejiang generation as an example, outdoor hydrangea with a temperature below 30 degrees Celsius does not need sunshade.

Cutting steps:

Cut the nodes of the current year, cut shorter above the nodes, cut flat to retain the buds, and cut diagonally at the 5cm below; the cut should be flat and cannot be squeezed; the healthy branches with full bud spots should be used as cuttings, preferably semi-lignified branches that feel semi-woody.

two。 Cuttings are pruned and leaves are cut in half to reduce transpiration and photosynthesis.
