How to Plant a Pink Ball Tree

Pink ball trees can be purchased at local nurseries or ordered online when young plants become available in spring. Follow these tips for planting:

  • Select a site with full sun exposure and well-draining soil. Amend clay soils with compost.

  • Dig a hole 2-3 times wider than the container and 6-12 inches deep.

  • Carefully remove the plant from its pot, handling the stem minimally.

  • Place in the hole, keeping the top of the root ball level with the soil surface.

  • Backfill the hole with native soil, tamping down gently to remove air pockets.

  • Water thoroughly until moisture penetrates deeply.

  • Apply 2-4 inches of mulch around the base, keeping it a few inches away from the stem.

  • Stake the plant if needed for stabilization in windy areas.

Pink Ball Tree Care

Once planted, proper care will ensure your pink ball tree thrives. Follow these tips:

  • Watering: Water deeply 1-2 times per week to keep the soil consistently moist but not saturated. More frequent watering may be needed in hot, dry weather.

  • Fertilizing: Feed with a balanced fertilizer or compost in early spring when new growth appears. Repeat in summer if foliage looks pale.

  • Pruning: Prune right after blooming finishes to shape and remove spent flowers. Avoid pruning in fall.

  • Pest Control: Watch for aphids, spider mites, and scale. Treat with horticultural oil or insecticidal soap. Deer may browse leaves.

  • Winter Care: In zone 9 and warmer, the pink ball tree remains semi-evergreen. In colder zones, it will lose its leaves and should be cut back after frost. Apply winter mulch.

With proper site selection, planting, and care, the pink ball tree will thrive for years of beauty and enjoyment. Be prepared for this showstopper to turn heads in your garden when those vibrant pink blooms appear!
