Please help! Spray dormant oil today, or wait? (cold nights)

Stacey Collins

I have some young apple and pear trees, and want to try dormant oil this year. I know you're supposed to spray before the buds break (or is it before they even swell?!) but I also read on line that you dont want temps below 32 for 24 hours after spraying.

I haven't been able to spray yet, because every time night temps were over 32, it rained.

Today and tomorrow it will be in the high 40s during the day, but 25-32 at night. Then we have a string of warm, dry days after that.

My worry is that the buds are going to be too swollen if I wait any longer. Is it better to wait, and risk damage because buds are too mature, or do it today or tomorrow and risk nighttime low temps?
