Lemon balm (Melissa officinalis) often referred to as "Melissa", is a versatile companion plant ideal for your cannabis garden. Lemon balm repels mosquitoes and fungus gnats while attracting beneficial pollinators to your garden. This multipurpose plant is extremely invasive and can quickly carpet your garden and strangle other plants if not kept in check. If regular garden maintenance is not possible, we recommend planting the lemon balm in pots to keep it from growing out of control. Regularly pinch out the flower spikes to encourage vegetation. At season's end, lemon balm will die back and hibernate over winter only to come on in a rush once the warmth of spring arrives. The reappearance of perennials is a good way to judge when it is time to germinate your cannabis seeds.
