Why hydrangea blooms in 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. Often the plant is used in landscape compositions. Hydrangea inflorescences can change color and turn green. When the first signs appear, measures must be taken.

Varieties of hydrangeas that bloom green

Gardeners often ask why hydrangea blooms in green. The reasons may be different. There are even varieties whose buds have a green tint. These include:

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

Green Hydrangea Varieties

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

Soil acidity and its effect on hydrangea color

The reason why hydrangea flowers turn green may be the type of soil at the place of shrub growth. Soil acidity is one of the common causes of discoloration of buds. The plant prefers an acidic soil type. Acidity should be closely monitored. The optimal 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 inflorescences have a bluish tint;
• at pH 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. This may fade the leaves.

Reasons for the appearance of green flowers

A green tint on the buds may appear as a result of the influence of external factors.

Natural causes

Some varieties of white hydrangeas tend to change the shade of inflorescences. Tree hydrangeas at the beginning of flowering form green inflorescences. Before finding out the reason why hydrangeas appear green flowers, carefully monitor the plant.

There are natural causes for changing the shade of inflorescences

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

• Frequent rains - with prolonged precipitation, useful nutrients are washed out of the soil.
• Long droughts - arid weather negatively affects the development of the bush. Most often, the inflorescences are deformed, the brightness and shade of the buds are adjusted.

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

• Wrong watering. Despite the fact that the plant prefers moist soil, it is not recommended to use a large amount of liquid. The soil is moistened as the soil dries. Inadequate watering negatively affects the culture. A lack of moisture leads to improper development of the flower.
• Lack of top dressing. Targeted types of fertilizers should be used. Some nutrients increase or decrease the acidity of the soil, resulting in a change in color.

In some cases, buds can turn green as a result of an attack by 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 shrub care

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

• Water the bush once every few days after the soil is completely dry. It is recommended to spray the leaves with a spray bottle after sunset.
• Carefully watch that pests that deplete the culture do not appear. At the first signs, special chemicals (insecticides) are used.
• Timely make top dressing. Involve complex mineral supplements designed for a particular variety. Excessive amounts of one substance lead 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 of long flowering

Change soil acidity

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

• In areas of 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 the culture.
• Peat and coniferous bark are used to file soil.
• To accurately determine the type of soil, litmus strips are used.

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