White hydrangeas: general characteristics

White hydrangeas are plants belonging to the Hydrangecee family and come from Japan and China. The European name hydrangea is linked to a very beautiful story: Philibert Commerson, in fact, who introduced this flower to Europe in the eighteenth century, decided to call it after the woman he loved, Hortense Lapaute. The hydrangea family includes several shrub and woody species; among these the most common varieties are certainly the Hydrangea macrophylla (which includes flowers of different colors), the Hydrangea peniculata and the Hydrangea Annabelle which gives rise to white hydrangeasbest known and cultivated in our gardens. The leaves of these plants are bright green, crossed by veins, deciduous and with serrated edges. The flowers represent a peculiar feature of this species of plants as they are gathered in globular inflorescences.

White hydrangeas: cultivation

Before you decide to plant white hydrangeasit is recommended to select a species suitable for the climatic and environmental conditions of the place where we live. Among the hydrangeas with white inflorescences we remember in addition to the Annabelle quite resistant to cold, the Pegee that grow well in both hot and cold areas, the oak leaves that prefer only very hot environments and the macrophylle also able to develop only in dry environments . In any case, white hydrangeas are quite robust flowers whose cultivation should preferably be started in the spring or winter season. The first thing is to choose the place to plant them which will have to be exposed to sunlight in the morning and partially in the shade in the afternoon. At this point, dig holes twice as deep as the root ball.

White hydrangeas: how to take care of them?

Once our white hydrangeas have been planted, we must learn to take care of them, in order to make them grow healthy and luxuriant. First you need to know that white hydrangeas and hydrangeas in general need a sufficiently moist soil and therefore must be watered particularly frequently, especially in the summer months. At the same time it is necessary to make sure that the soil is sufficiently drained in order to avoid stagnation and rot, which could lead to the death of the plant. If white hydrangeas have been planted recently, they must not be pruned, as pruning could compromise the birth of the buds. Finally, even in cases of white hydrangeas belonging to a cold-resistant species,

White hydrangeas: diseases and pests

White hydrangeas can fall ill after being attacked by pests or pests. Among the parasitic pathogens we mention Hydrandea virus, Botrys and Oidium. The Hydrandea virus manifests itself with a slowdown in the growth of the plant, and with the opacity of its aerial parts. Botrys is a fungus that manifests itself in the form of a white powder and that can be fought with specific fungicides. Finally, the Oidium is a fungus that can arise in particular dry conditions, and produces whitish spots on the plant. To prevent the formation of this fungus, it is enough to guarantee the necessary water supply to the white hydrangeas. Infestations by animal parasites concern attacks by nematodes, spider mites or snails.
