Two years ago I planted three Forsythia shrubs along our lot line. One was from a nursery and the other two cost $1 each at an Aldi grocery store. Last fall, the "nursery" shrub re-bloomed and I have no idea why. This spring, the re-bloomer is bone- bare, no leaves, no flowers. The $1 shrubs are lush, green and flowered like crazy.
I'm thinking the nursery shrub is gone and, luckily, the others have some "rooters" I can put in its place but I'd sure like to know what happened and why. Any ideas?
