Tip #6: Rhododendrons

Rhododendrons serve as the majestic, evergreen backbone of many woodland gardens, but they quickly decline and suffer in compacted, alkaline soils. These robust shrubs evolved to grow in the deep humus of shaded forest floors, surrounded by decaying leaves and natural organic debris.

Applying coffee waste beautifully replicates this natural, woodland-like soil texture while actively preventing the dense compaction that leads to devastating fungal diseases like root rot.

The organic grounds physically separate soil particles, facilitating excellent drainage while acting as a gentle, slow-release natural plant fertilizer. Refresh the growing environment by top-dressing the earth around the main stem with a half-inch layer of used grounds each spring. Pull the grounds and surrounding mulch at least two inches away from the actual woody trunk.
