Care
Watering
Yellow melilot is undemanding once established and tolerates relative dryness. Water regularly during the first year after planting to promote root development. After that, occasional watering during prolonged dry spells is sufficient.
Sunlight Exposure
Plant melilot in full sun for abundant flowering and optimal growth. It tolerates partial shade but will produce fewer flowers. Avoid heavily shaded areas and ensure at least 6 hours of direct sunlight daily.
Pruning and Deadheading
Melilot is typically grown as a one or two-year plant and doesn't require significant pruning. You can cut back stems in late autumn or at the end of flowering to encourage better branching if desired. Remove spent flowers to extend blooming.
Soil and Drainage
Yellow melilot adapts to most soils and tolerates even poor or slightly alkaline terrain. Ensure good drainage to prevent root suffocation. In compacted soil, improve structure by incorporating compost.
Fertilization
A modest feeder, melilot doesn't require regular fertilization. Thanks to its legume family, it fixes atmospheric nitrogen. A moderate application of compost in spring is generally sufficient.
Health and Pests
Melilot is relatively resistant to diseases and pests. In overly humid conditions, watch for root rot. Occasionally monitor for aphids, though they rarely cause serious damage. Good air circulation prevents most problems.
Did you know?
Yellow melilot was widely cultivated in the Middle Ages for its traditional aromatic and medicinal properties. Its name comes from the Latin « mel » (honey) because its flowers attract bees abundantly. It's also an excellent green manure: it enriches soil with nitrogen and was often sown in agricultural rotations to regenerate depleted land.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
