Water thoroughly, then let the top 2–3 cm of mix dry before watering again. Citronella grass prefers steady moisture in heat without sitting soggy. Reduce sharply in cool weather when growth slows. In practice, water every 3–5 days in hot summer sun; every 7–10 days in cooler months. Water when the top 2–3 cm is dry; never leave the crown in standing water. Keep pots evenly moist in India’s hot season; cut back hard in winter or cool spells.
Citronella grows best in full sun - 6+ hours of direct sunlight daily.
Citronella is toxic to cats, dogs, rabbits, horses, turtles, and tortoises. Keep out of reach of curious pets and choose pet-safe alternatives for accessible spots.
Propagate Citronella from healthy stem or root divisions during active growth.
Use sandy-loamy potting mix that drains fast. Add 20–30 % coarse sand or perlite and a modest compost portion. Avoid heavy, water-retentive mixes. pH 5.5–7.0. A good mix includes 50% potting mix, 30% coarse sand or perlite, 20% compost. Fast drainage is essential; soggy crowns rot quickly.
Citronella prefers moderate to high (50–80%); suited to tropical Indian climate. Normal household humidity is usually fine.
Repot Citronella every 1–2 years, or when the clump crowds the pot rim, ideally in spring to early summer once nights stay warm. Signs it needs a bigger pot: clump pressing hard against pot walls, mix drying within a day in summer heat, crown rising above the soil line.
