Care Guide

Watering

Water frequently to maintain even moisture, especially during dry spells.

Fertilization

Apply a light, nitrogen-rich organic feed to encourage leafy growth.. Requires minimal fertilization if planted in nutrient-rich soil; focus on nitrogen for foliage.

Coffee Grounds Tea:Steep used coffee grounds in water overnight, strain, and use the liquid to water the plants. This provides a gentle nitrogen boost for leafy growth. Avoid applying thick layers of uncomposted grounds directly to the soil surface to prevent mold.
Pruning
  • Harvest outer leaves continuously (cut-and-come-again method) when they reach 10-15 cm;
  • Leave the central crown intact to allow for regrowth;
  • Remove any yellowing or damaged leaves immediately to maintain airflow;
  • Pull the entire plant if it begins to bolt (send up a tall flower stalk), as leaves will become bitter.
