Pampas Grass Care
Cortaderia selloana
A giant ornamental grass that stands out for its large, plumed flower heads. The leaf edges are razor sharp. It can be invasive in some regions.
Monthly care calendar
Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.
- Pruning: Prune just before the shoots break. Because flowers form on this year's new shoots, hard pruning increases flowering. The leaf edges are sharp: use thick gloves, long-sleeved clothing, and goggles. At the end of winter, cut the whole clump to a height of 20-30 cm.
- Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
- General care: Good time for planting and transplanting.

- Watering: In a long drought, water deeply once a month.
- Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. Water so that the soil is wetted to a depth of 10-15 cm from the surface.
