Why hydrangea blooms green and what to do

One of the favorite plants for gardeners is hydrangea. This is due to the attractive appearance of the bush and the variety of varieties. The plant is often used in landscape compositions. Hydrangea inflorescences can change color and turn green. When the first signs appear, you need to take action.

Hydrangea varieties that bloom green

Gardeners often have a question, why does hydrangea bloom green? The reasons may vary. There are even varieties whose buds have a green tint. These include:

• Limelight - a variety of hydrangea differs in the height of the bush. An adult plant can grow up to 2 meters. Panicle-shaped inflorescences have a greenish tint. Over time, they turn pale pink. The features of the bush allow you to create unique flower arrangements.
• Sterilis - refers to tree-like bushes. At the beginning of flowering, the buds are green, which gradually changes to white.
• Magical Candle - the bush can reach one and a half meters in height, the shoots are strong, erect. During the flowering period, the buds are light green, eventually turning pink.

The listed varieties are popular among gardeners and are undemanding to care for. In some cases, the shade of the buds changes depending on external factors that affect the growth of the plant.

Soil acidity and its effect on the color of hydrangeas

The reason why hydrangea flowers turn green may be the type of soil in the place where the shrub grows. Soil acidity is one of the most common causes of color changes in buds. The plant prefers an acidic type of soil. The acidity indicator must be closely monitored. The optimum value for the growth of bushes is pH 5.5.

The acidity of the soil can affect the color of the buds as follows:

• at pH up to 5.5, the inflorescences have a bluish tint;
• at a pH of more than 6.5, the appearance of pink and purple is noticeable.

With insufficient acidity in the soil, the buds acquire a light green color. In this case, the leaves may fade.

Natural causes

Some varieties of white hydrangeas tend to change the shade of the inflorescences. Treelike hydrangeas form green inflorescences at the beginning of flowering. Before figuring out the reason why hydrangea has green flowers, carefully observe the plant.

There are natural reasons for the color change of inflorescences.

Hydrangea sometimes blooms green in adverse weather conditions. These include:

• Frequent rains - with prolonged precipitation, beneficial nutrients are washed out of the soil.
• Prolonged droughts - dry weather negatively affects the development of shrubs. Most often, the inflorescences are deformed, the brightness and shade of the buds are corrected.

After normalization of weather conditions, the problem disappears. Failure to follow simple grooming rules is the main explanation why hydrangea flowers turn green.These errors include:

• Improper watering. Although the plant prefers moist soil, it is not recommended to use a large amount of liquid. The soil is moistened as the soil dries. Insufficient watering can negatively affect the culture. Lack of moisture leads to incorrect development of the flower.
• Lack of dressing. Targeted types of fertilizers should be used. Some nutrients increase or decrease the acidity of the soil, resulting in a color change.

In some cases, the buds can turn green as a result of the attack of pests. At the same time, the flower weakens and does not form healthy buds. The bush may not bloom at all.

What to do

In order for the plant to develop normally and not change the shade of the buds, it is important to take timely measures when the first symptoms appear.

Make adjustments to the care of the shrub

When the hydrangea changes its shade, it is worth revising the rules of care:

• Water the bush every few days after the soil is completely dry. It is recommended to spray the leaves with a spray bottle after sunset.
• Watch out for pests that deplete the culture. At the first sign, special chemicals (insecticides) are used.
• Make top dressing in a timely manner. Complex mineral additives are used, intended for a specific variety. An excessive amount of one substance leads to disturbances in the flowering process.
• Protect the plant from excessive exposure to sunlight.

In some cases, it is recommended to transplant the plant to a new site. This will saturate the roots with the necessary substances.

Proper care is the basis for long-lasting flowering

Change the acidity of the soil

To obtain the required acidity level, the following steps should be taken:

• In areas with low pH, substances such as chalk and dolomite flour are added to the soil.
• In areas with a high level of acidity, sulfur components and aluminum sulfate are used. These substances are necessary for the normal development of culture.
• Peat and coniferous bark are used for sawing the soil.
• To accurately find out the type of soil, litmus strips are used.

When growing hydrangeas, gardeners often face the problem of changing the color of the buds. The most common cause is improper maintenance or the wrong type of soil. To fix the problem, you should revise the care procedure, since a color change can signal the appearance of irreversible processes.
