Soil

The optimum soil is sandy, with a low to mediocre quality. This is one plant that does not like soil that is high in organic matter. It can thrive in fertile soil, but it will most likely grow too quickly and become “leggy,” causing the stems to flounder under the weight of heavy blossoms.

The pH level of the soil should be between 4.0 and 8.0. A score of 6.4 is seen to be ideal. Although the soil quality may be poor, drainage must be adequate. Yarrow is not a plant that tolerates moist soil or thrives in humid circumstances.

Fertilizing

Yarrow is a low-maintenance plant. A compost side-dressing once a year should be enough. An overabundance of nutrients in the soil may foster the proliferation of the Yarrow plant. Once the seeds have sprouted, apply a heavy nitrogen fertilizer. In the second year, expect blossoms.

Invasiveness

If not adequately managed, this plant may become invasive in particular areas or ecosystems, displacing valuable plants. Although Yarrow is a low-maintenance plant, it has the potential to overpower other plants in your yard, so keep an eye on it. Dig a trench and remove the plant out from its rhizomes if your plant starts to overwhelm your garden or yard.

Growing Yarrow In Containers

The plant, a member of the daisy family, is ideal for container gardening. Because the plant grows swiftly, the seed is typically a better (and less expensive) alternative. The seeds, unusually, require light to germinate, so maintain them in a warm, sunny location. Germination might take up to three weeks. The common Yarrow may reach a height of 40 inches. When planting seeds or transferring seedlings, use a big potting container to allow this growth.

Care & Tips

Once established, Yarrow, a tough plant, works hard in the garden, especially if you remember these four gardening tips:

If necessary, select humidity-tolerant cultivars.

  • For compact plants that develop at a moderate rate, poor soil is preferable to rich soil.
  • Drought tolerance does not imply that they never need water.
  • Plants should be spaced 1 to 2 feet apart to allow for easy establishment.
  • Give your plants a solid start, and they’ll give you years of color in return for a little maintenance.

Common Problems

Yarrow is a disease-free plant in general, making it one of the easiest to maintain in the garden. It is, nevertheless, susceptible to a few pests and illnesses. Powdery mildew usually emerges later in the season, especially in hot and dry conditions. Remove any powdery mildew-affected areas of your plants.

Rust is a fungal disease that starts on the underside of leaves and spreads to the rest of the plant. Make sure diseased leaves are removed, and trash is raked away. To get rid of this illness, use copper sprays or sulfur powders. Spittlebug leaves a protective foam on your plants that resembles spit. The insect is protected from UV radiation, predators, and pesticides by its spit nest.

Spittlebugs can be removed by spraying them with a forceful stream of water. You may also use UV lamps to destroy the bugs or attract predators like spiders and wasps.

Propagating Yarrow

Loosen the soil surrounding your plant and dig it up with a spade to start the division process. With a spade, cut the plant in two. You may divide it up as many times as you like, as long as each part includes three shoots. Dig holes in a sunny, well-drained spot to plant a fresh piece. The ideal time to propagate Yarrow from stem cuttings is between late spring and summer. Look for a stem that is fresh and robust, with three to four buds. The length of the growth will be around 6 inches. Late winter is the optimum time to start growing Yarrow from seed. You can use a pot if you’re simply putting a few seeds.

The History Of Yarrow 

Naturalized in North America, Australia, and New Zealand, it is native to Europe and western Asia. Herba militaris was the name given to Yarrow in antiquity because of its function in stopping the flow of blood from wounds. The plant (Achillea millefolium) was called after Achilles, the Greek mythological hero who employed it to staunch the bleeding wounds of his warriors during the Trojan War around 1200 BC, according to herbal mythology.

It is known as plumajillo (Spanish for ‘small feather’) in New Mexico and southern Colorado because of its leaf form and texture.

Uses For The Yarrow Plant

The plant is used to treat a variety of ailments. Fever, common cold, lack of menstruation, hay fever, dysentery, loss of appetite, diarrhea, gastrointestinal (GI) tract pain, and inducing perspiration are all treated with Yarrow.

However, Yarrow products containing the chemical thujone may not be safe. In excessive dosages, thujone is dangerous. When used in quantities of 250-500 mg daily for 12 months, Yarrow may be considered safe. 

If you’re seeking the ideal border or ground cover, the plant might be the plant for you. It attracts pollinators and requires little maintenance once established.

Yarrow is a fragrant herb with medicinal characteristics that can be used to treat a variety of diseases. So, Yarrow may be grown in both flower beds and herb gardens.
