Fertilizer

Fertilizing American arborvitae ‘Bobozam’ MR. BOWLING BALL is essential for ensuring balanced growth and vibrant foliage. Here are some guidelines for fertilizing this plant:

  • Timing: Apply a balanced, slow-release fertilizer in early spring before the new growth begins. Avoid fertilizing late in the growing season, as it may stimulate late-season growth that can be vulnerable to frost damage.
  • Application Rate: Follow the recommended application rate for the specific fertilizer product, and avoid over-fertilizing, as excessive nutrients can be detrimental to the plant.
  • Formulation: Consider using a fertilizer specifically formulated for evergreen shrubs to provide the necessary nutrients in the right proportions.

Soil

The right soil conditions are crucial for the overall health and performance of American arborvitae ‘Bobozam’ MR. BOWLING BALL. Here’s what you need to know about soil preferences for this cultivar:

  • Well-draining Soil: Ensure that the soil is well-draining to prevent waterlogging, which can lead to root rot and other issues.
  • Fertility: The plant thrives in fertile soil, so amending with organic matter such as compost can improve soil fertility and structure.
  • pH Level: American arborvitae prefers slightly acidic to neutral soil with a pH range of 6.0-7.0. Conduct a soil test to determine the pH and make any necessary adjustments.

Pruning

Pruning American arborvitae ‘Bobozam’ MR. BOWLING BALL is essential for maintaining its compact and rounded shape. Proper pruning practices can also help improve air circulation and sunlight penetration within the plant, reducing the risk of disease. Here are some pruning tips for this cultivar:

  • Timing: The best time to prune American arborvitae is in early spring before new growth emerges. Avoid pruning in late fall, as it can leave the plant vulnerable to winter damage.
  • Deadwood Removal: Remove any dead, damaged, or diseased branches as soon as they are noticed to prevent the spread of disease and maintain the plant’s overall health.
  • Shape Maintenance: Use hand pruners or hedge shears to trim the outer foliage and maintain the desired rounded form of the plant.

Propagation

Propagating American arborvitae ‘Bobozam’ MR. BOWLING BALL can be achieved through several methods, including cuttings and layering. Here are some common propagation techniques for this cultivar:

  • Softwood Cuttings: Take softwood cuttings from the current season’s growth in late spring or early summer. Dip the cut ends in a rooting hormone and plant them in a well-draining propagation medium.
