I said above I may post a sequence of spring sickness that I photographed one year (2007) - I wanted to document its progress. Here is the first picture, taken on May 15
Next was on May 27
Lastly, taken on July 30
You'd think I'd have been smart enough to take one or two in between the middle and the last but apparently not. The end result was the same anyway, it got over it by itself and flowered. Whether bud count was reduced or not I don't know, it does look a little less than this year's on the same cultivar, now a multi-fan clump with 15 scapes, despite a ninebark bush growing right in the middle of it
This is not to make light of what spring sickness can do at its worst, but to show that they can and do recover on their own and the sufferers are not necessarily wimpy plants.
