Care Guide

To care for Rhododendron Latoucheae, it is important to provide it with the right conditions. Here are some tips:- Water: Keep the soil consistently moist but not waterlogged. Rhododendrons prefer slightly acidic soil, so avoid using hard tap water. Rainwater or distilled water is best.- Fertilization: Use a slow-release, acid-loving fertilizer in the spring and fall. Avoid fertilizing in winter, as this can damage the roots.- Soil: Rhododendrons prefer well-draining, slightly acidic soil that is rich in organic matter. If your soil is too alkaline, you can amend it with sulfur or iron sulfate.- Sunlight: Rhododendrons prefer partial shade to full shade. They can tolerate some morning sun, but avoid placing them in direct afternoon sun.- Hardiness Zones: Rhododendron Latoucheae is hardy in USDA Zones 7-9.
