🐶 🐈 👶 Toxicity

Great Rhododendron is extremely dangerous if consumed. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian immediately. Great Rhododendron is not recommended for homes with children, cats, or dogs.


💨 Humidity

Great Rhododendron doesn’t require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.


🪴 Soil

Great Rhododendron is very sensitive to dry soil, so choose a potting soil that retains moisture. A good soil will still drain well and contain lots of organic matter such as coco coir or sphagnum moss.


💩 Fertilizer

Great Rhododendron should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!
