A new home owners and yard work. I remember when I looked forward to that. The best thing about winter is I can totally ignore the endless lawn and garden maintenance except of course for the driveway . 😉
I once read that shrubs, trees etc. that need pruning, it was recommended to prune / shape about 6 months prior to blooming. According to that this would be a good time to prune March, April and May bloomers.
Many shrubs have their buds set already. Azalea's, rhododendrons, for a few. Any trimming will remove any blooming possibilities for next Spring.
I would identify all the shrubs you have and look up the pruning recommendations.
If the ground isn't frozen, you can still plant bulbs for Spring. Here on Long Island, I can easily dig in the soil this year due to the warm temperatures.
