| Maintenance | Pruning ground cover Junipers can be challenging. Most people tend just to trim the ends, which results in pointed stubbed branches after a few years. To avoid this, you need to lift the outside branches and cut the underneath branches. After that, feather back the top branches to the crotch of a branch. This method will create a much softer outside edge of the shrub. You may also notice some branches that die for no apparent reason. In such cases, you should use pruning shears to cut them out. Doing so will help to clean up the plant, allowing light to reach the shrub and promote new growth. Keep in mind that Junipers are prickly, so it's advisable to wear gloves and a long-sleeved shirt. |
