Yarrow (Achillea millefolium) is a hardy perennial plant that produces clusters of tiny, delicate flowers in shades of white, pink, and yellow. It is a popular choice for gardeners due to its easy care and attractive appearance. One of the key factors for successfully growing yarrow is to plant it at the correct depth. In this article, we will explore how deep yarrow plant needs to be planted to ensure its healthy growth.
Yarrow plants should be planted at a depth of approximately 1/4 inch to 1/2 inch (0.6cm to 1.3cm). This is because yarrow has shallow roots and can become stressed if planted too deeply. Planting yarrow too shallowly can also be detrimental as it may dry out quickly or become dislodged easily by wind or rain.
When planting yarrow, it is important to prepare the soil well by removing any weeds, rocks, or debris. Yarrow prefers well-draining soil with a pH between 6.0 and 7.5. It is also recommended to mix some compost or aged manure into the soil before planting to provide extra nutrients for the plant.
To plant yarrow, follow these steps:
Yarrow plants should be spaced approximately 18 inches (45.7cm) apart to allow for their spreading habit.
Once planted, yarrow requires minimal care and maintenance. It is a drought-tolerant plant that can withstand hot, dry conditions. However, regular watering during the first few weeks after planting is essential to help the plant establish its roots.
Yarrow plants do not require fertilization. In fact, too much fertilizer can cause the plant to become leggy and floppy. If you wish to encourage bushier growth, you can pinch back the stems by one-third in early spring.
Yarrow plants may benefit from division every three to four years to prevent overcrowding and maintain their vigor. Division should be carried out in early spring or fall when the plant is dormant.
A: Yes, yarrow can be grown in pots as long as they are large enough to accommodate its spreading habit. Use a well-draining soil mix and ensure the pot has drainage holes.
A: Yarrow is a drought-tolerant plant but requires regular watering during the first few weeks after planting to establish its roots. After that, it only needs occasional watering during prolonged dry spells.
A: Yes, yarrow is a magnet for pollinators such as bees and butterflies due to its nectar-rich flowers.
A: Yarrow prefers full sun but can tolerate partial shade. However, it may produce fewer flowers in shady locations.
A: Yarrow can spread quickly and may become invasive in some areas. It is recommended to divide the plant every three to four years to prevent overcrowding.
