It's essential to water deeply and less frequently to encourage the roots to grow deeper into the soil, which helps the plant withstand drought better. Avoid overhead watering to keep the foliage dry and prevent disease. Allow the soil to dry out between watering sessions to prevent root rot. Depending on weather conditions, you may need to adjust your watering schedule.

  • circleLife cycle

    Achillea 'Schwellenburg', commonly known as Yarrow, begins its life as a seed, which under the right conditions of warmth and moisture germinates to produce small seedlings. These seedlings grow into juvenile plants with characteristic feathery foliage and establish a strong root system. As the plant matures, it enters the vegetative stage, during which it develops more leaves and branches in preparation for reproduction. The reproductive stage is marked by the formation of flower heads composed of numerous tiny, tightly packed flowers which are often visited by pollinators. After pollination, seeds are produced and dispersed, and the plant eventually reaches senescence where it dies back, especially in colder climates, though it can be a perennial, regrowing from its rootstock each spring. Throughout its life, Yarrow will experience repeat blooms and may spread through vegetative means via rhizomes or stolons in addition to seeding.

      Spring-Early Summer

    • Achillea 'Schwellenburg', commonly known as Yarrow, can most popularly be propagated by division, which is best done in the early spring or fall. To propagate by division, carefully dig up an established Yarrow plant, ensuring you have a good amount of roots. Gently separate the clumps into smaller sections, each with several shoots and a healthy root system. Replant the divisions immediately into well-draining soil, spacing them approximately 1 to 2 feet apart (about 30 to 60 cm), and water thoroughly. Divisions will establish themselves quickly and begin to grow, filling in the space, and will often flower in the first season after propagation.
