Mason Bee Mud Box


Availability: In stock

Short Description

The Mason Bee Mud Box, through capillary action, helps to ensure a clayey mud consistency that can be easily gathered by nesting spring mason bees. Water storage bin eliminates the need for daily watering. Mason Bee Mud Mix is included!



Why Great Mud is important!
The mason bee protects each nesting chamber with clayey mud. Without a source of moist clayey mud nearby, mason bees will fly away.

The correct moisture content of the clayey mud is important to bees. Arid locations and rooftop gardens struggle to keep their mud mix wet.

The Mason Bee Mud Box solves this challenge with capillary action!

Using capillary action, water stored below the mud takes an elevator ride up the black cloth, runs horizontally under the clay allowing the clay to wick up the right amount of moisture.

Depending on weather conditions, the water level in the storage bin may last one to two weeks before refilling is required. Includes Mason Bee Mud Mix!
