I am in Rhode Island and last spring I bought two forsythia bushes and planted them about four feet apart. One of them flourished but the other one died so I pulled it out about five weeks ago and planted a new one from a big box store. It was in a plastic pot and I removed the pot but did not break up the dirt around the roots very much. I planted it in the same hole as the previous one. I am noticing now that the bush from last year is doing fine but the new one had some yellow buds over the past ten days to two weeks but they seem to be disappearing daily. I did water it when I planted it and we have received rain in our area since....What did I do wrong and is the bush salvageable at this point?
