What happened to my wisteria?
I have a large wisteria that I planted about 5 years ago. It has bloomed like crazy every year. It was completely covered with buds (either leaf buds or flower, can never remember which comes first). Today I noticed that all of the buds are dry and crispy. I broke off a piece of the vine and it is still green inside. This spring got warm very early, then we had a few days of cold temps. Not sure if it could have gotten hit by frost. I'm not too concerned about loosing a year of flowers, although it would be nice to see some bloom. I'm much more worried about the vine being OK. Any ideas? Thanks, Lisa
