Q.Why is my Pampas Grass not getting tall?
I have a giant Pampas Grass planted the first year the grass and plumes got to be nine feet tall–the last two years it hasn’t gotten more than four feet. Why is it not growing. The plant looks healthy and green. The original plant grew above the wall.
Soil fertility and water management are the keys to plant health and normal growth.
Fertilize and irrigate appropriately and you may see a big difference.
