How to fertilize Rosebay Rhododendron

Most potting soils come with ample nutrients which plants use to produce new growth.

To replenish this plant's nutrients, repot your Rosebay Rhododendron after it doubles in size or once a year—whichever comes first.

Sunlight Needs
Rosebay Rhododendron requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.
Toxicity
Rosebay 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. Rosebay Rhododendron is not recommended for homes with children, cats, or dogs.
Humidity
Rosebay 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
Rosebay Rhododendron does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
Fertilizer
Rosebay Rhododendron grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
Native Region
Rosebay Rhododendron is native to Asia and North America.
Growth Pattern
Rosebay Rhododendron grows vertically and new growth will emerge from the top of the plant.
