Care Guide

Watering

Water regularly to keep the soil evenly moist but not waterlogged.

Fertilization

Coffee Grounds Tea:Steep used coffee grounds in water overnight, strain, and use the liquid to water the plant. Provides a gentle nitrogen boost for leafy growth. Avoid applying thick layers of raw grounds directly to soil to prevent mold.
Pruning
  • Harvest outer, older leaves first to encourage new growth from the center;
  • Snip stems close to the ground rather than just pulling off leaves;
  • Remove flower stalks immediately if you want to prolong leaf production.
