Am I killing my hydrangeas?
Have I killed my hydrangeas because I pruned them improperly or at the wrong time? I have four mature hydrangeas on the property I bought 3.5 yrs. ago, 2 of which did not bloom at all this year. The others did quite well. One is a blue mop-head of some sort & the other is a lace cap. The lace cap bloomed a lot last year then I think I over pruned it, so it didn't do a thing this yr. The leaves looked kind of icky & spotty all summer, (but it was shaped very nicely!)
Also, I planted 2 Pink Elfs 2 yrs. ago. One bloomed for 3 months straight (May, June, July, a bit of Aug.) & was spectacular, while the other (in slightly more shade, same soil) got about 2 blooms on it all season! Once again, I trimmed the good Pink Elf & now it seems to have black spot! The leaves look hideous. The Elf that didn't bloom (that I also didn't trim) has lush green foilage & no spotting. I also planted two Tovelits in the spring & they have ugly leaf spot even worse (they are still quite small & haven't bloomed, so I haven't trimmed them). What am I doing wrong? I don't want to lose these plants!
