Pusillus Miniature Sweet Flag problems — and how to fix them
Pusillus Miniature Sweet Flag (Acorus gramineus 'Pusillus') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Drying out
Its tiny blades brown almost immediately if the substrate dries. Maintain constant moisture or a shallow water source at all times.
Melting when fully submerged
Marketed for aquariums but not a true aquatic; kept permanently underwater it slowly thins and rots. Grow it emersed or only partly submerged.
Algae in wet displays
In bright, nutrient-rich terrariums and aquaria, algae can smother the low tufts. Limit feeding and moderate light intensity.
Very slow growth
Establishes and spreads slowly, which gardeners mistake for poor health. Be patient and avoid over-feeding to force growth.
