01
Overview
Dwarf sagittaria is what most people actually want when they ask for a low-tech carpet: a dense, ankle-high grass that spreads on its own initiative. It tolerates hard water and casual care, and its runners work fast enough to watch week to week.
02
Aquascaping use
Let it run as a foreground-to-midground meadow with taller plants emerging from it. It fits both community tanks and harder-water setups where picky carpets fail.
03
Planting
Plant starts a few centimeters apart, crowns above the line, in decent substrate. It may briefly melt, then runs with enthusiasm.
Nutrient-bearing substrate
04
Light & CO₂
Medium light keeps it short; in shade it stretches toward fifteen-plus centimeters and stops being a carpet. CO₂ unnecessary.
05
Substrate & fertilization
Root tabs through the meadow zone sustain runner pace; it also forages the water column. Iron shortage shows as pale new blades.
Feeding behavior: Root feeder. Nutrient demand: moderate.
06
Growth, trimming & propagation
Pull runners that cross borders and thin clumps to ground level where congested. Mowing blades midway leaves brown tips, so thin instead of shearing.
Runner separation
07
Common problems
- !Height varies with light; shade defeats the ‘dwarf’
- !Runners invade neighboring plantings
- !Occasional melt on introduction
