Layout Material
The small stuff that holds a scape together. Thread, glue, line and mesh are what turn a pile of wood and rock into a planted layout — and the difference between moss that anchors in three weeks and moss that sloughs off in a cloud usually comes down to technique with these rather than the plant.
Thread or glue?
Cotton thread is the traditional answer and still the best one for moss. Wrap it thin, tie it off, and it rots away over a few weeks — by which point the plant has attached itself and there is nothing left to remove or hide. Moss cotton and moss thread are sold in exactly the thickness that disappears against dark hardscape.
Cyanoacrylate gel — aquarium plant glue — is faster and better for rhizome plants. Anubias, bucephalandra and java fern attach slowly enough that thread often rots before the roots grip, so glue wins. Use the gel, not liquid: liquid runs everywhere. It cures on contact with water and turns opaque white, which looks alarming for a day and then vanishes under the plant. It is inert once cured and safe with shrimp and fish.
Nylon line holds indefinitely and does not rot, which is what you want for a heavy piece you will move, and a nuisance when you want it gone. Use it where it will sit under substrate or behind the plant mass.
The rhizome rule
Anubias, bucephalandra and java fern have a horizontal rhizome — the thick stem the leaves and roots grow from. Bury it and it rots, every time. These plants are meant to be tied or glued onto wood and stone with the rhizome fully exposed, roots left to find their own way. This is the single most common reason a healthy anubias melts a month after planting.
Tying moss properly
Thin. A dense wad of moss dies from the inside because nothing reaches the middle — light, flow and nutrients all stop at the surface. Spread it in a single loose layer over the surface you are covering and let it fill in. It will look sparse for two weeks and correct for months.
Riccia and floating plants
Riccia does not attach to anything. It is held down mechanically — tied under line against a stone, or pressed under mesh — and it will escape wherever the tension goes slack. Trim it regularly; ungroomed riccia lifts off in a sheet as it traps oxygen.
What we stock
Moss thread and cotton, plant glue, riccia line and stones, wood tight and terrestrial base material for wabi-kusa and paludarium builds. Small items, mostly under ten dollars, and worth picking up before a build day rather than mid-scape with wet hands.
Or come scape one with us
Technique is faster to watch than to read. Our Drop-In & Aquascape sessions at Convoy are exactly this — bring a tank or use ours, and we will show you the tying and gluing on a real build. See finished work at the Hakkai Aquascape Gallery.
