  • Maintaining juniper height:

    Although low growing junipers will maintain a consistent height they will continue to spread throughout their life, requiring periodic maintenance to contain them within a desired area. They should be planted in anticipation of a 6-8' spread and will grow considerably larger if allowed.

  • Pruning:Pruning animation

    Regular pruning on spreading type junipers is very important to maintain the desired size and to avoid makor reconstructive pruning.

    Cut back the most vigorous shoots inside the body of the plant where they meet another branch. This will reduce the size of the plant while maintaining a natural appearance.

    This type of pruning may be done prior to new growth in spring or in mid-July.
