I need to move 4 blueberry plants that are relatively small but producing. The area where they are planted is being annexed into my sheep corral/barn area and the sheep eat pretty much everything that has a leaf on it. Being this late into the growing season, do I need to try to just take the plants and the dirt they are in all at once and basically not disturb the roots, or can they be dug up and re-planted in new soil? These thigs are only about 2ft tall but they all have berries and seem to be doing really well.
