Amazon Sword problems

No. The Amazon Sword sold for aquariums is a freshwater aquatic plant. Keep it submerged in a stable aquarium and do not treat it like a potted terrestrial plant.

Use nutrient-bearing aquarium substrate or inert gravel with aquarium-safe root tabs. Plant the roots but leave the central crown uncovered.

Nursery plants may have leaves grown above water that decline after being submerged. Remove clearly dying leaves, keep the crown exposed, and watch for healthy new submerged growth while maintaining stable tank conditions.

The common ‘Bleherae’ form is rated as undemanding and low-light tolerant. Low-to-medium aquarium light is a reasonable starting point; avoid sudden increases that can trigger algae or outpace root-zone nutrients.

Usually not in a typical low-tech aquarium. Root-zone nutrition, stable water conditions, and enough room for the rosette are more important for basic growth; supplemental CO2 can increase growth in some planted tanks.

Wait until a flower-stalk plantlet has several leaves and visible roots, then separate it and plant the roots in aquarium substrate while leaving its crown exposed.

Amazon Sword is an aquatic aquarium plant, not a potted houseplant. Keep its roots submerged in freshwater and maintain a stable tank environment suited to the fish and invertebrates sharing the aquarium. It does not need separate top-watering; routine aquarium top-offs and water changes should follow the needs of the whole tank. In practice, water there is no plant-only watering schedule while it is fully submerged. Keep the water level stable, and perform water changes according to aquarium stocking, filtration, and water-test results rather than a fixed plant calendar. Check leaf condition, new growth, water quality, and the substrate around the crown. Yellowing older leaves or persistently small new leaves can have several causes, including nutrient limitations, so check root feeding and tank conditions before changing the light or fertilizer. Indoor aquariums do not follow outdoor seasons in the same way as garden beds. Growth may slow when tank temperature or lighting changes; keep water conditions steady and adjust care to the aquarium’s livestock and equipment.
