ðą How to Care for Carolina mosquitofern to Prevent Curculionidae?
ð§ How to Water
This is an aquatic plant: it has to float on water at all times and dies within hours if it dries out. Top up evaporated water, keep the surface calm (strong filter flow or splashing that wets the top of the fronds causes rot) and avoid salty or hard, alkaline water.
âïļ Lighting
Give it bright light or partial sun â about half of full sunlight is ideal. Strong light turns the fronds red, which is normal. In deep shade or weak aquarium light it stops growing and the mat thins out.
ðŠī Ideal Soil
It needs no soil; the roots hang free in the water. Growth depends on the water itself: slightly acidic to neutral pH, some phosphorus (red, stalled fronds signal a shortage) and a little iron (yellow fronds signal iron deficiency). In an aquarium, a light, regular dose of liquid fertilizer helps.
