I have a few 10-12 foot tall bushes that i need to take down to about 3 feet so that people can see around them at an icecream shop. I was wondering if this is too early to cut thoes down. I have had people tell me that it is not just as long as i get them before they start to bud. i would like to do it later this week because it is supposed to be 45ish degrees. So is it too early?
