When can I trim these blue spruce bushes?

by Erin
These blue spruce bushes are starting to take up a lot of room in my yard. Can I trim them down? And if so what time of the year. I live in PA. Thanks for any help.

    I rather like them! And if that's all the bigger they'll get I'd leave them as is. I love those kinds of shrubs in the landscaping - always green and no maintenance.

      @Darlene Littleton the blue spruce will eventually reach a height of up to 70 feet, but it is a slow growing tree.

    generally trees can be trimmed all year but it's best if done at the end of winter or the very early spring before the sap starts flowing

    Spruce trees are not meant to be pruned. It will distort their look and it may force them to start growing upward if you prune the lateral growth. I agree with Darlene. Once they fill in I think you may actually like the results.

    i'd be more worried about that grass in the center there. If its what I think it is, it will spread quickly and probably choke out the evergreens. I love the spruce, it hides a lot of sins.

      For sure..those grasses need cutting every year.

    I like them too, they look nice. I would suggest that whenever they put on their new growth just snap them off. that will keep it more subdued.

    I Think those are called "birds nest" spruce. They are extremely slow growers. Snapping off the bright green new growth each spring will contain growth.
