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.
