The intense colors of the hydrangea flowersmake these shrubs wonderful plants for bedding. By planting them in the garden, we want them to decorate it as long as possible. Meanwhile, it happens thathydrangea loses the color of flowersor leaves. It doesn't look so pretty then. See the explanation ofwhy the hydrangea loses its colorand what to do. Here are 3 possible causes for this problem!
Why does hydrangea lose color?
Hydrangea loses color due to incorrect soil pH
In the case of garden hydrangea, the color of the flowers largely depends on the acidity of the substrate . In very acidic soils, the flowers are intensely blue. Pink on alkaline soils.
Sometimes it happens that we plant a blue hydrangea, and after some timethe flowers become pale and paler, the hydrangea loses its color , and sometimes it turns pink. This is because the color of flowers depends largely on the pH value of the soil.
Only highly acidic soils make the flowers of the hydrangea intense blueBy planting the garden hydrangea in a substrate with the addition of peat, special mixtures of acidic hydrangea substrate and by adding aluminum compounds (e.g. alum)the color of hydrangea flowers can be influencedSpecialist fertilizers for hydrangeas are available in garden stores to obtain an intense blue color of flowers.
Sometimeshydrangea loses color of not only flowers but also leavesThis usually happens when hydrangea grows in a substrate with a very high pH. The hydrangea leaves turn pale and pale while the veins remain green. In this case, use acidifying fertilizers (e.g.ammonium sulphate), acid peat and pine bark, which we sprinkle under the plant, creating a layer of mulch.
Hydrangea loses color because it discolours naturally
Bouquet hydrangea comes in a very large number of varieties. Each of them differs in size of flowers, shade and the way in which it blooms. When buying a bouquet hydrangea in a specific variety, it is worth knowing its characteristics. Sometimeshydrangea loses color because this is due to its natural life cycleand is not a negative phenomenon at all. Bouquet hydrangea 'Grandiflora' has cream-white flowers and maintains this color throughout the flowering period. On the other hand, the hydrangea 'Limelight' first turns greenish-yellow, and thenthe flowers of this hydrangea lose their green color and become creamy whiteThe variety 'Pinky Vinky' from cream or pale pink, turns intensely pink.
Hydrangea loses color because it is being fed by a pest
The loss of leaf color in hydrangeas is often due to the pest's feeding.The spider mite feeds from May to mid-August on the underside of the leaf, sucking the sap from the plant's cells. As a result of feeding the spider mitethe hydrangea loses its color, turns pale, leaves turn yellow, dry at the edges and fall offKarate Zeon 050 SC.
