Leaves Suddenly Turned Black /Brown
In our unusually warm spring my hydrangeas started sprouting up from the ground about 2-3 weeks ago. I planted them last year.
Last time I walked around the garden (4-5 days ago) I saw that many / most of the newly sprouting leaves had curled up and turned black and brown. It already seems like newer growth is coming out still, but I can't tell if this affliction is yet to happen again.
Was this due to
1. A below 32 degree night we had after some warm days
2. Lack of water? I haven't watered yet this year. Rain levels are below average but I never water this early in the season
3. Some disease ? Insect?
I haven't grown hydrangeas in awhile, but many years ago, at another house I lived in I planted a China Blue and pretty much did nothing to it (except move it around a couple of times) and it absolutely flourished. This due to no help from me! When I drive by there now and then I still see it huge and beautiful.
I didn't know it could/would be so challenging this time. I am growing Endless Summers this time.
