Azalee / Rhododendron - Winterschutz


Azalee / Rhododendron - Winterschutz
Azaleen / Rhododendren benötigen je nach Art Winterschutz. Die "Northern Lights" -Reihe der University of Minnesota ist für das Zentrum von Illinois extrem robust.

Wenn Sie eine Azalee / Rhododendron pflanzen, wählen Sie einen geschützten Ort aus der Wintersonne und dem Winterwind. Die meisten Pflanzen bevorzugen einen schattigen Standort

Pflanzen sollten nach dem 1. Juli nicht mehr gedüngt oder beschnitten werden. Neuwüchsigkeit hat möglicherweise nicht genügend Zeit, um für den Winter verholzt und abgehärtet zu werden.

Jungpflanzen können mit Maschendraht oder Hundezäunen umschlossen und lose mit Eichenlaub gepackt werden. Entfernen Sie den Schutz im Frühling, während sich die Knospen ausdehnen.

Reife Pflanzen können mit mehreren Zoll Hackschnitzel an der Basis gemulcht werden. Immergrüne Zweige können gegen Pflanzen gelehnt oder gebunden werden, um die Winterverletzung zu begrenzen.

Ein Anti-Trockenmittel kann verwendet werden, um zu verhindern, dass der Winter trocknet. Lesen und befolgen Sie alle Anweisungen zum Buchstaben. Die meisten sind eine "wachsartige" Substanz, die während der Wintertauwolken schnell abgebaut werden kann und eine erneute Anwendung erfordert.

FAQ - 💬

❓ What is the problem with rhododendrons?

👉 These include fungal leaf spots, leaf and flower gall, root rot, oedema, leaf flooding, winter injury, and chlorosis.

❓ Do rhododendrons like sun or shade?

👉 Traditional rhododendrons thrive in filtered sunlight and acidic soil. Newer varieties can tolerate a range of sunlight conditions, but always check the plant tag or description when shopping to make sure the plant needs match your garden conditions.

❓ Do I need to cover my rhododendron in the winter?

👉 Preventing Rhododendron Cold Damage Since rhododendrons root much more shallowly than other plants, it's extra important to keep a thick layer of mulch over this delicate system. 4 inches (10 cm.) of an organic mulch, like wood chips or pine needles, is often adequate protection from the cold.

❓ How do you treat lace bugs on rhododendrons?

👉 For adult lace bugs, recommended spray insecticides include acephate, bifenthrin, lambda cyhalothrin, malathion, and cyfluthrin. Acephate may give the best control, as this insecticide is a foliar systemic that will move through the leaves to kill the lace bugs on the undersides of the leaves.

❓ What kills a rhododendron?

👉 Damping-off and root rot, Rhizoctonia solani. This fungus is widespread and causes more trouble with rhododendrons than is generally realized. Rhizoctonia can kill small or large bushes or just keep them in poor condition. Symptoms may include small necrotic spots on leaves, which later become dark brown or black.

❓ How long does a rhododendron live?

👉 The average lifespan of rhododendron is tens to hundreds of years when given the proper care and living in the correct climate. The oldest known rhododendron is an estimated 131 years old!

❓ Where is the best place to plant rhododendron?

👉 Unlike many blooming plants, rhododendron does not like full morning sun in winter and does best when planted in dappled shade on the north side of a building. Growing rhododendrons are happiest in a location protected from the wind and not under eves of a building.

❓ Do rhododendrons lose their leaves in winter?

👉 Normal: While we think of rhododendrons as evergreen, they do drop leaves just as conifers periodically shed needles. Some rhododendrons hold their leaves for a season, dropping the older leaves in spring, fall or both seasons. Other varieties can hold their leaves for three or even four seasons.

❓ Can rhododendron survive a freeze?

👉 Certain rhododendrons and deciduous azaleas can survive temperatures as low as -35°F (-37°C). It is normal for some rhododendrons to exhibit leaf droop and curl at around 32°F (0°C).; the lower the temperature the tighter the curl. Leaf movement occurs rapidly and it is reversible as temperature warms.

❓ How do I prepare my rhododendron for winter?

👉 Rhododendrons are shallow-rooted plants; in cold regions, apply several inches of organic mulch around the base. In regions with severe winters, wrap evergreen rhododendrons with burlap in the fall. Cold, dry winds will cause too much moisture evaporation from the leaves which will wither and die.

❓ What to spray on rhododendrons for bugs?

👉 Of the few rhododendron insect problems that exist, most can be handled first through prevention or subsequent treatment with neem oil.

❓ Are azaleas and rhododendrons susceptible to diseases and pests?

👉 Where growing conditions are unsuitable, azaleas and rhododendrons are susceptible to the disorders and diseases described below. Rhododendrons and azaleas prefer similar growing conditions: cool, moist, well-drained, acidic soil (pH between 4.5 and 5.5), partial sunlight (morning sun and afternoon shade), and protection from strong winds.

❓ Is Rhododendron atlanticum a coastal azalea?

👉 Rhododendron atlanticum (Coastal Azalea) Native to the south eastern coastal plains of the United States, Rhododendron atlanticum, commonly known as Coastal Azalea or Dwarf Azalea, is a delightfully fragrant, semi-dwarf, deciduous Azalea.

❓ What is the difference between Pink Rhododendron and azaleas?

👉 Dandy Man pink rhododendron blooms grow in clusters at the end of each plant. Size: Rhododendrons are generally larger flowering bushes, with some growing 20 feet wide. Foliage: Most of the leaves are bigger, evergreen and more leathery than the ones that grow on azaleas.

❓ How do you protect azaleas from frost?

👉 Since the frost damage is generally caused when the early morning sun strikes the plants' frozen tissues, you should site your Azalea or Rhododendron where both leaves and flowers are protected from the early morning sun, and where they will adapt slowly to the increasing temperatures of the day.
