Why do hydrangeas turn green? Here’s how to get pink and blue flowers

Hydrangeas are a real decoration and the pride of the gardens of many Belarusians. Beautiful lush inflorescences attract the eye, decorate the space and give a feeling of comfort. However, sometimes the flowers turn colorless and green. Why does this happen and how to solve this situation?

Greening of hydrangeas is a fairly common problem, but before you start looking for its source, you need to consider the type of plant. For varieties such as Pistachio, Annabelle, Green Shadow, and Little Lime, greening of the flowers is natural. However, if your hydrangea is not one of these, then the reason for the greenness of the flowers lies elsewhere.

Why do hydrangeas turn green?

Hydrangeas are known for their rich pink, blue, and white flowers, but over time they may begin to turn green. This phenomenon can be difficult for gardeners, who expect shrubs to produce lush, bright flowers throughout the season. There can be a variety of reasons for this phenomenon, not all of which are obvious.

• The natural life cycle of flowers
  The most obvious reason for hydrangeas to turn green is the natural life cycle of the flowers. As hydrangeas age, they go through different color stages. After an initial period of intense blooming, their color may gradually fade and take on a greenish hue, which is a normal stage in their maturity.
• Effects of Soil pH
  Soil pH has a significant effect on hydrangea color, especially for certain hydrangea varieties. The flowers will change color depending on the acidity or alkalinity of the soil. Acidic soil (lower pH) will produce hydrangeas with blue tones, while alkaline soil (higher pH) will produce pink tones. When the soil loses its original acidity or alkalinity, the color of the hydrangea may fade and the flowers may begin to turn green.
• Nutritional deficiencies
  A lack of nutrients, especially phosphorus, can also cause flowers to change color. Malnourished plants may produce less of the pigment that contributes to color intensity, causing the flowers to slowly shift to green.
• Excessive sunlight and temperature changes
  Excessive exposure to sunlight can affect the amount of chlorophyll in the petals, causing the flowers to appear greener. Hydrangeas prefer partial shade, and too much sunlight can change their color. Cool nights and hot days can also affect the color of hydrangeas. Drastic changes in temperature can stimulate the production of chlorophyll in the petals, causing the petals to appear greener.
• Plant health issues
  Sometimes, blooms turning green can be the result of disease or pest infestation that can weaken the plant and affect its ability to retain its vibrant color. Therefore, you should monitor the health of your plant regularly and respond to any disease symptoms, such as leaf spot, wilt, or the presence of pests.

How to prevent hydrangeas from greening?

The key to hydrangea color is controlling the pH of the soil. Add aluminum sulfate Works into the soil, acidifies it and promotes appearance Blue tintone Soil lime Helps maintain the pink color.

It is also necessary Use fertilizers rich in nitrogen, phosphorus and potassiumThis is best done in spring, early summer, and late summer. They will then receive the necessary amounts of nutrients throughout the growing season.

Hydrangeas prefer semi-shaded locations so that they are not exposed to direct sunlight for most of the day. Therefore, they should be planted in a location that can receive morning sun and avoid strong afternoon sun and strong cold air.

How to feed hydrangeas?

To get a specific color for your hydrangea, you need to change the pH of the soil. Blue Shade, then you need to add to the soil:

• Potassium alum;
• Aluminum sulfate;
• Colloidal sulfur.

If the soil is slightly acidic or alkaline, Add vinegar. Dilute in the following proportions: 100 ml per 10 liters of water. Water the bush twice a month.

exist Pink If the acidity of the soil decreases, hydrangeas will change color. To this end, gardeners contribute Dolomite, chalk or limestoneb. Phosphorus can also be used.

Use caution. If the soil is too alkaline, the shrub may appear chlorotic and stop blooming.
