The best time of year to replant pampas grass is in late winter and early spring. Pampas grass is a versatile plant that thrives in warm climates where the soil is moist and there is plenty of sunshine.
Pampas grass is a hearty, ornamental perennial grass that, once planted, can grow in almost any soil. The pampas grass can grow up to 5 feet in height and is almost impossible to get rid of. It is best to plant pampas grass under controlled conditions where it cannot spread and consume an entire green space. Some states and countries have bans on pampas grass, including Hawaii, California and New Zealand, because it spreads very easily.
