ToxicityTo humans
Rhododendrons, including the Rhododendron Volker Group, contain toxic compounds that can be harmful to humans if ingested. The plant contains grayanotoxins which can affect sodium channels in cell membranes, leading to a variety of symptoms. Poisoning from rhododendron can cause vomiting, diarrhea, hypersalivation, weakness, coma, hypotension, CNS depression, cardiovascular collapse and potentially death. Consuming any part of the plant, including leaves, flowers, and nectar, can lead to these toxic effects. It is important to seek medical attention immediately if ingestion occurs.
To pets
Rhododendrons are equally toxic to pets as they are to humans. Ingestion of any part of a rhododendron by an animal can lead to severe poisoning. Symptoms of toxicity in pets can include vomiting, diarrhea, drooling, weakness, seizures, coma, and potentially death if left untreated. All parts of rhododendrons, such as leaves and flowers, contain the harmful grayanotoxins, and both dogs and cats are susceptible to the toxic effects. If you suspect your pet has ingested rhododendron, it is imperative to seek immediate veterinary care.

WaterRhododendrons, including the Volker Group, prefer consistently moist soil but not waterlogged conditions. They should be watered thoroughly when the top inch of soil feels dry to the touch, which often equates to once or twice a week, depending on weather conditions. Use water at room temperature, with the amount of 1 gallon for a medium-sized shrub each time, ensuring the root zone is well-saturated. During hot or dry periods, additional watering may be necessary. Over the course of a month, a mature rhododendron may require 8-12 gallons, adjusted for rainfall and temperature.
LightRhododendrons, like the Volker Group, thrive in dappled shade or partial sun, protected from harsh afternoon sunlight. The best spot for these plants is one where they can receive morning sunlight and shade in the afternoon, or filtered light throughout the day for optimal growth and bloom performance.
TemperatureRhododendrons, including the Volker Group, prefer moderate temperatures and are hardy in a range of conditions. They can generally tolerate minimum temperatures down to around -5 to -10 degrees Fahrenheit, and maximum temperatures up to 80-85 degrees Fahrenheit. The ideal temperature range for rhododendrons is between 50 and 70 degrees Fahrenheit to promote healthy growth and flowering.
PruningRhododendrons, including the Volker Group, should be pruned for shaping, size control, or to remove dead and diseased wood. The best time to prune is right after the blooming period as new buds are set shortly after flowers drop. Thinning out dense growth every few years encourages air circulation and healthy new shoots. Light pruning can be done annually if needed.
CleaningAs needed
SoilRhododendrons, including the Volker Group, prefer acidic soil with a pH of 4.5 to 5.5. The best soil mix should be well-draining and rich in organic matter. A mixture containing peat moss, pine bark, and perlite in equal parts is often recommended to maintain proper moisture and aeration.
RepottingRhododendrons, like the Volker Group, should be repotted every 2 to 3 years or as needed when they become root-bound. It's best to repot them in the spring, just before they enter their active growth phase.
Humidity & MistingRhododendrons, such as the Volker Group, thrive in moderate to high humidity levels, ideally between 40% to 60%. They benefit from a moist, but not wet, environment, so maintaining these humidity levels is crucial for their growth.
Suitable locationsIndoor
Place in bright, indirect light with acidic soil; keep humidity high.
Outdoor
Partial shade, acidic, well-draining soil, protect from strong winds.

Life cycleThe Rhododendron 'Volker Group' begins its life cycle as a seed, typically requiring a cold stratification period to break dormancy. Upon germination, it develops into a seedling with distinct rhododendron features like its characteristic leaves. As it grows into a young plant, it requires acidic soil, partial shade, and consistent moisture. It reaches maturity in several years, developing a woody structure and an extensive root system. The mature rhododendron produces clusters of colorful flowers annually in spring, attracting pollinators for reproduction. After flowering, the plant sets seed, which can be dispersed to begin new life cycles while the parent plant continues to grow and flower for many years.
PropogationPropogation time
Spring to early summer
For the Rhododendron, which is the common name for the Volker Group, the most popular method of propagation is through semi-hardwood cuttings, typically done during the late summer. A cutting of about 4 to 6 inches (10 to 15 centimeters) is taken from healthy, non-flowering shoots. The leaves on the lower half of the cutting are removed, and the cut end is dipped in rooting hormone to encourage root development. The cutting is then planted in a mixture of peat and perlite, ensuring good drainage and moisture retention. It's important to maintain a humid environment, which can be achieved by covering the cuttings with a plastic bag or placing them in a propagator. Proper care will result in root development over several weeks, after which the new Rhododendron plants can be gradually acclimated to less humid conditions before being transplanted outdoors.
