Bauernhortensie

In rauen Lagen benötigen Bauernhortensien / Ballhortensien einen Winterschutz.

Die Blaufärbung ihrer Blüten hängt übrigens vom Säuregrad der Pflanzerde ab: je saurer, desto bläulicher, je kalkiger, desto rötlicher! Möchte man die blaue Blütenfarbe fördern, düngt man im Frühjahr mit einem Spezialdünger, nämlich mit einem sauer wirkenden Aluminiumdünger.

 

So werden BAUERNHORTENSIEN und TELLERHORTENSIEN richtig geschnitten:

Bauernhortensien (Hydrangea macrophylla) und Tellerhortensien (Hydrangea serrata) haben ihre Blütenknospen bereits im Vorjahr angelegt und

• werden deshalb im Frühjahr nicht geschnitten, damit man sich im Sommer an ihren Blüten erfreuen kann! Man entfernt nur oberhalb des obersten Knospenpaares die braunen, alten Blütenstände und eventuell erfrorene Triebspitzen.
• Möchte man jedoch die Pflanze etwas auslichten, schneidet man die ältesten Triebe auf Bodenhöhe ab.
• Wenn Sie alle Zweige zurückschneiden, blühen diese Hortensien frühestens erst im nächsten Jahr wieder.

So werden SCHNEEBALLHORTENSIEN bzw. STRAUCHHORTENSIEN und RISPENHORTENSIEN richtig geschnittten:

Schneeballhortensien bzw. Strauchhortensien (Hydrangea arborescens) und Rispenhortensien (Hydrangea paniculata) blühen am „diesjährigen Holz“, d.h. an den Zweigen, die ab dem Frühjahr bis zum Sommer  n e u  wachsen!

• Sie werden deshalb im Frühling geschnitten: Mitte März - Mitte April, sobald keine Dauerfröste mehr zu erwarten sind, greifen Sie zur Schere und lassen von den Zweigen, die im vergangen Jahr geblüht haben, jeweils nur eine Handbreit übrig.
• Schwache einzelstehende Triebe werden ganz entfernt.

So werden KLETTERHORTENSIEN richtig geschnitten:

• Die hübsche Klettererin wird nicht regelmäßig geschnitten: Überalterte Triebe können entfernt werden. Ein Rückschnitt im Frühjahr, falls aus baulichen Gründen nötig, wird vertragen.

 

Landscape Uses:Container, Seashore, Specimen. Tolerates most soil, thriving in a well-drained loamy soil, but resenting dryness at the roots. Succeeds in full sun or semi-shade, but if it is grown in a low rainfall area then it requires shade at the hottest part of the day. Prefers a shady position. Does well on very acid soils with a pH around 4.5. Plants also tolerate alkaline soils, though they become chlorotic on shallow soils over chalk. The colour of the flowers reflects the pH of the soil the plant is growing in, the flowers are pink in a neutral to alkaline soil and blue in an acid soil. A very wind resistant plant when grown in mild areas. Dormant plants are hardy to about -10°c, though the young growth in spring is frost-tender[K]. A very ornamental plant and polymorphic species, there are many named varieties. This species was named for a sterile (or 'mop head') cultivar so that the true species should really be referred to as H. macrophylla normalis. Plants are cultivated for their leaves in China and Japan. Plants are very tolerant of pruning and can be cut back into old wood if required. This species is notably susceptible to honey fungus. Special Features:Not North American native, All or parts of this plant are poisonous, Suitable for cut flowers, Suitable for dried flowers, Blooms are very showy.

Edible Parts: Leaves Shoots Edible Uses: Sweetener The young leaves, when dried and rubbed between the hands, become very sweet and are used to make a sweet tea called 'tea of heaven', it is used in Buddhist ceremonies. The leaves contain phellodulcin (its chemical formula is C16 H14 O), a very sweet substance that can be used as a sugar substitute. One small leaf is sufficient to sweeten a cup of tea. The older leaves can be dried, powdered and used as a flavouring on foods. The young leaves and shoots are also eaten cooked. Young leaves contain the toxin hydrocyanic acid, this reduces as the leaves grow older, often to zero levels.

Hedge Hedge A useful hedging plant because of its vigorous growth. The Hortensias or mop-head cultivars are recommended.
