Bonsai Gravel for Humidity Trays and Soil Top Dressing
This decorative bonsai gravel is most commonly used inside humidity trays, but it can also be used as a top dressing on the surface of your bonsai soil for a more finished appearance.
When used in a humidity tray, the gravel creates a layer between the tray and your bonsai pot. This helps keep the pot and roots from sitting directly in water. Instead of resting in standing water, the bonsai sits on top of the gravel while the tray below provides added humidity around the tree.
Most Common Use: Humidity Trays
To use with a humidity tray, simply add the gravel to the tray first, then place your bonsai pot on top of the stones. Add water to the tray, but keep the water level below the bottom of the pot.
- Helps keep the bonsai pot above standing water
- Supports proper use of a humidity tray indoors
- Adds a cleaner, more finished presentation
- Available in multiple colors and stone styles
Most popular for humidity trays: White Pea Rock, River Rock 3, and River Rock 4 are among the most popular choices because they tend to look the most natural in a humidity tray setting.
Also Great for Soil Top Dressing
Some bonsai owners also use this gravel as a top dressing on the soil surface. It can improve the finished look of a planting, add contrast, and help create a more decorative presentation.
Top dressing gravel is especially useful when you want a cleaner display surface or when older top dressing has washed away over time.
