What this plant likes (and what it hates)

Light

  • Best: Direct
  • Avoid: harsh midday sun if leaves scorch, or deep shade if growth gets weak

Watering

  • Rule of thumb: water based on the soil, not the calendar
  • Target: Moderate watering habits
  • Common mistake: keeping the pot wet for days at a time

Soil and pot

  • Use a pot with drainage holes.
  • Choose a mix that matches watering needs.
  • If the plant stays wet for too long, use a chunkier mix and a breathable pot.

Common problems and quick fixes

Here are the issues people hit most often with Lemon balm.

  • Leaf spots: usually light change, watering swings, or a stressed root system
  • Root rot risk: often low humidity, mineral buildup, or inconsistent watering
  • Brown tips: can be thirst, heat stress, or early root trouble
  • Moldy soil: often overwatering, stale airflow, or splashy watering

A quick diagnosis checklist

  1. Check the soil moisture 2 inches down.
  2. Look at the newest growth first.
  3. Inspect the underside of leaves.
  4. Confirm drainage and airflow.

Pest watch

These are the most common pests to check for:

If you are unsure, the fastest move is a clean photo of the underside of a leaf and a close shot of the damage.

Propagation basics

  • Best time: spring through early fall
  • Method: depends on the plant, but clean cuts and fresh water or airy mix matter most
  • Tip: slow propagation usually means low light or cold temps

Safety notes

If you have pets or small kids, treat toxicity seriously. Even mild toxicity can cause drooling or stomach upset.
