About Mandarin Lemon Balm

Mandarin Lemon Balm is a specialty cultivar of the traditional lemon balm distinguished by its distinctive mandarin orange scent rather than the typical lemon aroma. This perennial herb features a spreading growth habit, reaching 12-24 inches tall and 20-24 inches wide, with bright green serrated leaves and small white flowers that attract pollinators. It makes an excellent ground cover, container plant, or 'spiller' in mixed gardens with its trailing growth pattern and vibrant citrus fragrance.

General Care Instructions

Sunlight Requirements

  • • Requires 6-8 hours of direct sunlight for optimal growth and flavor
  • • Tolerates partial shade (4-6 hours of direct sun)
  • • Morning sun with afternoon shade works well in hot climates
  • • Insufficient light leads to leggy growth and reduced essential oils

Temperature Range

  • • Ideal growing temperature range: 70-90°F (21-32°C)
  • • Protect from temperatures below 50°F (10°C)
  • • Will suffer damage or die when exposed to frost
  • • Growth slows below 60°F (15°C) and above 95°F (35°C)
  • • Optimal soil temperature for germination: 70-85°F (21-29°C)

Fertilizer Requirements

  • • Container plants: Half-strength balanced liquid fertilizer every 2-3 weeks
  • • Garden plants: Balanced organic fertilizer monthly
  • • Begin fertilizing when plants are 4-6 inches tall
  • • Reduce feeding in late season to prevent excessive leaf growth
  • • Signs of deficiency: yellowing leaves, stunted growth, pale foliage
  • • Avoid high-nitrogen fertilizers which reduce essential oil content

Watering Needs

Newly planted

  • • Keep soil consistently moist but not soggy
  • • Water when top half-inch of soil feels dry
