It is a gentle and enjoyable process to check for the structural integrity of delicate ZERO Moss species with a glass rod (sometimes with tweezers, too) to ensure that they can withstand the rigorous movements when they travel across the world.
We also give extra attention to rare preserved moss species and moss with a more eye-catching appearance to ensure that they are well transplanted.
Complete preservation in our lab retains the main characteristics of moss, such as its fluffiness. That would also mean that the nature of moss is well preserved, such as the tendency to dislocate part of its leaves as "moss fragments", which is one of the ways moss propagate in nature.
Thus, we often select moss before its peak reproductive stage to preserve it for optimal aesthetic and structural stability in our botanical collections & preserved moss terrariums.
