Is 45 Degree Weather Too Cold to Water a Lilac Bush?

Question

I bought a lilac bush this summer and my state has been in a drought this year. Although I have been watering my bush all summer, I haven’t watered it too much lately. It is 45 degrees out now and I am wondering if that is too cold to water my bush? Jennifer Lindsay, MN

Answer 1

It is not too cold for watering, though the plant does not require as much now that the temps are getting cooler and dormancy nears. You will only need to water when the soil gets particularly dry.
