I purchased 5 pampas grass starter plants (in containers) in the fall of last year and kept them on my deck over the winter months to protect them from the cold. I topped them off in early March of this year and put them in the ground. Under normal conditions, when can I expect to see some growth? It is now April 11th and I’m seeing nothing. I live in central Oregon and weather here can (at times) be extremely cold over the winter months. Could I have lost them because of the winter weather or, do I just need to be more patient. Thank you for your response.
The pots alone may not have offered enough insulation for the Pampas Grass root system survival from the cold.
When plants are in pots they are more vulnerable to freeze and thaw.
I would wait a bit longer to see if you see any growth. Time will tell.
