Mason bees need clay mud in order to build their nests and protect their young. Without a good source of soft clay mud, they will not be able to nest.
Similar to slip in your ceramics studio, this powdered mud soaks up moisture and creates a soft, pliable mud perfect for mason bees' masonry work!
A small saucer filled with pebbles makes a great container for this! Just be sure to keep it moist so mason bees can use it as they need!
