White Yarrow

Garden Seeds

White yarrow (Achillea millefolium) is a resilient, multi-purpose plant long valued for its role in companion planting, soil health, and traditional herbal use. In the garden, it functions as both support and protector, quietly working alongside neighboring plants to improve balance and biodiversity.

For cannabis growers, white yarrow is especially appreciated for its ability to attract beneficial insects. Ladybugs, hoverflies, and parasitic wasps are naturally drawn to yarrow’s small clustered blooms, helping control aphids, whiteflies, and other soft-bodied pests that commonly affect cannabis plants.

Yarrow is also considered a nutrient accumulator, drawing minerals like potassium from deeper soil layers and making them more available in the surrounding garden. Many growers believe its presence supports stronger aromatic development in nearby plants, making it a common addition to terpene-focused, living-soil gardens.

Highly drought tolerant and low maintenance, white yarrow thrives in sunny, well-draining areas without competing heavily for water, making it an ideal companion plant in both in-ground and container grows.

Planting Tips:

• Start: Indoors 6–8 weeks before last frost or direct sow outdoors
• Depth: Lightly press into soil (needs light to germinate)
• Spacing: 18–24″ apart
• Germination: 14–21 days
• Light: Full sun
• Soil: Poor to average, well-draining soil

A trusted companion plant commonly grown near cannabis, vegetables, and herbs to support a balanced and resilient garden.
