Care Guide

Watering

Water deeply when the top 2-3 inches of soil become dry.

Fertilization

Apply a balanced, slow-release fertilizer at the start of the growing season.. Avoid over-fertilizing, which can lead to leggy growth and reduced wind resistance.

Coffee Grounds Tea:Steep used coffee grounds in water overnight. Use the diluted liquid to water the plant, boosting lush foliage growth. Avoid applying thick layers of raw grounds directly to the soil to prevent mold.
Pruning
  • Prune in late winter or early spring before new growth begins;
  • Tip-prune regularly to encourage dense, bushy growth;
  • Remove any dead, damaged, or crossing branches to maintain airflow;
  • Can be sheared formally for hedging, though this may remove potential fruiting sites.
