Canary Grass (Phalaris canariensis)

🌱

☀️

Sunlight Full sun to partial shade; tolerates moderate summer heat and dry conditions

💧

Watering Water deeply when the top 2–3 cm of soil is dry; avoid overwatering to prevent root rot

🌡️

Temperature Thrives in 15–25°C; tolerates light frost but cannot survive prolonged freezing temperatures

🔍

Leaf: Linear, flat, bright green blades 10–30 cm long with smooth, slightly glossy texture
Flower: Dense, cylindrical spikelets arranged in compact oval panicles 2–5 cm long, pale green to straw-colored at maturity
Stem: Slender, hollow, upright stems with evenly spaced nodes and smooth surface

🛠️

Watering

Keep soil consistently moist during active growth periods

Fertilization

Apply diluted balanced fertilizer once monthly. Avoid over-fertilization to prevent excessive foliage growth at the expense of seed production

Eggshell powder topdressing：Sprinkle finely ground, dried eggshells on the soil surface; avoid direct contact with stems to prevent fungal growth

Pruning

Trim spent flower heads after seed harvest to prevent unwanted self-seeding
Remove yellowing or damaged blades to maintain a tidy clump appearance
Cut back entire clumps to 5 cm above soil level after the first frost to prepare for winter dormancy
