How to keep yarrow blooming all summer?
When yarrow plants are finished blooming, plants can be cut back by a third to a half of their size to encourage a late-season rebloom. One of the easiest ways to encourage more blooms is through deadheading and light pruning. Removing old flowers prevents the plant from setting seeds, which can stop new flowers from forming. Instead, your plant redirects its energy into producing new blooms.Reasons to deadhead yarrow ‘Yarrow, like many perennials, will produce more flowers if it’s deadheaded,’ says landscaping pro Gene Caballero, co-founder of GreenPal. By removing spent blooms, you’re encouraging the plant to refocus its energy on producing new flowers rather than seeds.

Mulching around the plant will insulate the root zone and help drainage a bit.Watering: As a drought-tolerant plant, yarrow doesn’t need much water once established. Overwatering can lead to weak, floppy growth and increased susceptibility to diseases.Yarrow prefers full sun, lean soil and little water. When planting yarrow in the garden, avoid placing alongside other plants with different growing needs such as astilbe, begonias, coral bells and hosta.Yarrow prefers well-drained soil and thrives in hot, dry conditions. Avoid constantly wet or poorly drained soil, which can lead to root rot. Loamy soil is ideal, but yarrow tolerates clay soil if it drains well.

Is yarrow a sun or shade plant?
Yarrow really does best in full sun. In shade, it will grow, but it becomes tall and floppy, and doesn’t bloom much. In ideal growing conditions, yarrow spreads rapidly and sometimes aggressively.Underwatering, a non-infectious condition caused by inadequate water supply, can lead to slowed growth, wilting, and eventual death of Common yarrow. Symptoms are more prominent during hot, dry seasons, but remedies can help the plant recover.Yarrow’s Temperature Tolerance Yarrow is remarkably resilient, tolerating temperatures as low as -30°F (-34°C).
