I live in No California. I have two sky flower vines I planted last year. I'm afraid I'm losing them. I've been fighting a whitefly infestation. I've sprayed neem and when that didn't work I sprayed spectricide. I've fertilized too. I have no sign of buds.

They look pretty much the way you would expect this time of year. They'll look better in a month or so when it warms up.

It looks like they are being eaten and have black spots

A little late, but to the forum!
You might bait for snails, that could be what's making the holes. The black spots are probably from cold.

The 'spots' look like the bug holes.
No sign of buds because it's too early, they bloom in summer.

Can you give us a focused closeup of a damaged leaf, front and back?
