Q.How To Revive Pampas Grass That Was Replanted In Another Area
We live in Bellingham MA and pruned down the replanted pampas grass to the other side of the fence – about 2 feet away. It is still brown/tan and dead looking with no green pooping up. What can we do to revive the plant? We do not understand what 8-8-8, 10-10-10- fertilizer is or where to get it. Thank you in advance for your assistance, Sr. Elizabeth

This can come down to a few issues, like transplant shock, or pruning out of season. Wet soils that don't drain can prevent new clumps from establishing, but so can overly dry soils. You can poke around to see if the clump has any signs of life, or if the root ball is alive.

One other thing to consider is that most cultivars are only hardy down to zone 7. Yours is right outside of that at 6b. Without winter protection, there is chance for winter damage. Especially if this is a new transplant.
As far as NPK goes- These numbers refer to nitrogen, phosphorus, and potassium, respectively. The higher the number, the more potent. The same number for all three means that it is balanced. I cannot give you sources to purchase, but I can say that an internet search will provide several in your area.
