Why Aren't My Four O'Clocks Blooming?

Question

Thirty-five years ago I planted some Four O'Clocks. They have reseeded themselves every year and bloomed beautifully. Unitl this year. The bushes have plenty of blooms but they aren't opening. There is no sign of disease or bugs. They've had the same sunlight, rain, etc...as always. Anyone know what could be the problem? This is hardiness zone 8 but it's actually a little hotter than that, rarely gets as cold as 8 is supposed to be. It's very humid here. Thanks for any help.

Answer 1

Four O'clocks only bloom in the evening, after the sun goes down. Maybe it is hotter than usual, this year where you live. I live in SE Ohio, and mine aren't doing that well this year, yet, either.

Answer 2

If everything is equal (sun,water and location) I would have to say that your ground needs a little help with nutrients. Try adding miracle-gro.
