Temps For Nectarine Tree Spraying?

Question

Article says early Spring when temps get between 45-55 degrees. I assume that’s daytime temps? What about night-time temps? It could be 50 during the day but dropping to 32 at night. What’s the minimum night-time temps? Just trying to clarify things. Thanks.

Answer 1

This, simply, means that you should spray when it remains between these temperatures for a few hours. Just long enough to allow your spray to dry.

Answer 2

Thanks, that helps. In all the articles I read about spraying, no one ever explained the why.
