If you choose to grow Pampas grass from seeds outdoors, then they should be sown out either at the beginning of spring or late in autumn on the soil surface.
They prefer to grow in a sunny area of the garden, and prefer a moist soil (well drained though) that is rich in nature.
If you first plan to grow pampas grass (Cortaderia) seedlings indoors, then they should be started about 10 weeks before they are due to be planted out in either early autumn, or before the last frost of spring.
They normally take from two to three weeks to germinate, and should be grown in light at a temperature of between 15 and 24 degrees Centigrade.
It is important to water the seedling from below as they may decay if watered from above.
Once pampas grass seedlings are ready to be planted out they should be done at a spacing of one to two metres. If you require more plants then pampas grass should be divided at the beginning of spring.
