Frequently asked questions
How do I attach Java Moss to hardscape?
Spread a thin layer over the surface and hold it down with cotton thread, fishing line, or a dab of cyanoacrylate gel glue. It anchors itself with rhizoids within a few weeks; thin layers attach faster and look cleaner than thick clumps.
Why is my Java Moss turning brown in the middle?
Dense clumps shade their own interior, and the starved inner growth browns while the outside stays green. Trim it back regularly so light and flow reach the base, and the patch will stay green throughout.
