Plant Needs
Sunlight
Requires moderate indirect sunlight in shallow coastal waters; avoids extreme direct sun exposure during low tide
Watering
Submerged in continuous, oxygenated saltwater; dependent on natural tidal flow for nutrient exchange
Temperature
Thrives in cold, nutrient-rich saltwater; intolerant of temperatures above 18°C
Characteristics
- Thallus: Flat, ribbon-like blade with a central midrib and winged margins
- Stipe: Stout, cylindrical stipe attaching to rocky substrates via a fibrous holdfast
- Reproductive Structures: Sporophylls develop at the base of the stipe during reproductive seasons
Care Guide
Watering
Maintain continuous saltwater submersion; ensure adequate tidal flow for nutrient delivery
Fertilization
Obtains all necessary nutrients from surrounding saltwater; no additional fertilization needed. N/A
N/A：Not applicable for marine macroalgae; nutrients are obtained from natural seawaterPruning
- Remove damaged or decaying thallus sections to prevent spread of marine pathogens
- Clear accumulated sediment from the holdfast to maintain secure attachment to rocky substrates
- Avoid disturbing surrounding marine vegetation during maintenance activities
