How to plant and grow yarrow ?
Here's how to plant and grow yarrow in your garden:
Choose the right location. Yarrow prefers full sun and well-drained soil. It can tolerate a variety of soil types but will do best in a neutral or slightly alkaline soil with a pH level between 6.7 and 7.5.
Prepare the soil. Before planting, work the soil to a depth of 8 to 10 inches and remove any large rocks or debris. Work in a 2- to 4-inch layer of compost to improve the soil’s drainage and fertility.
Plant the yarrow. Yarrow can be planted from seed or from established plants. If planting from seed, scatter the seeds on the soil surface and lightly cover them with soil. If planting from plants, space them 12 to 18 inches apart.
Water the yarrow. Once planted, water the yarrow deeply to make sure the soil is evenly moist. Water regularly throughout the growing season, especially during dry periods.
Fertilize. Fertilize the yarrow in early spring with a balanced fertilizer. Follow the directions on the package for application rates.
Deadhead the flowers. To encourage continued blooming, remove spent flowers as soon as they start to fade.
Cut back the foliage. Once the yarrow has finished blooming, cut back the foliage to a height of 3 to 4 inches. This will help encourage new growth and prevent the plant from becoming leggy.
Caring for yarrow
Caring for yarrow is easy, and it can be a great addition to any garden.
Watering: Yarrow is a drought-tolerant plant, but it should be watered regularly during dry periods. An inch of water per week should be enough to keep it healthy. If the soil is allowed to dry out completely, the plant may suffer from drought stress.
Fertilizing: Yarrow doesn't need much in the way of fertilizer, but a light application of balanced fertilizer in the spring can help the plant reach its full potential. Avoid over-fertilizing, as this can cause the plant to become leggy and weak.
Pruning: Yarrow can become quite tall and leggy, so regular pruning is important for keeping the plant healthy and attractive. To prune, simply cut back the stems to the desired height. This should be done in the spring before the plant begins to flower.
Weeding: Yarrow does not compete well with weeds, so keeping the area around the plant free of weeds is important. Pull weeds by hand or use an appropriate herbicide.
Pest Control: Yarrow is generally resistant to pests and diseases, but it can suffer from aphids, spider mites, and occasionally fungal diseases. Treating the plant with an insecticidal soap or neem oil can help keep pests in check.
Harvesting: Yarrow leaves can be harvested throughout the growing season. To harvest, simply snip off the leaves with a pair of scissors. The flowers can also be harvested, but they should be cut carefully to avoid damaging the plant.
Water requirement for yarrow
While it is an easy plant to grow, providing it with the right amount of water is essential for success.
It is important to remember that the plant likes to be kept evenly moist. This means watering it regularly, but not too much. To accomplish this, water yarrow deeply once or twice a week, depending on the weather and soil conditions. In hot, dry weather or sandy soils, it may need to be watered more often.
It's also important to water yarrow at the right time of day. Water early in the morning, before the heat of the day has set in. This will allow the foliage to dry out before evening, reducing the risk of fungal diseases.
Finally, avoid overhead watering if possible. Yarrow’s delicate foliage can be easily damaged by sprinklers or other overhead watering methods. Instead, water at the base of the plant, or use soaker hoses or drip irrigation systems.
Diseases and pests affecting yarrow
Despite its popularity, yarrow can suffer from a number of diseases and pests, which if left untreated can cause significant damage to the plant.
The most common diseases affecting yarrow are powdery mildew and rust.
Powdery mildew is caused by a fungus and is characterized by white powdery spots on the leaves.
Rust is caused by another fungus and is identified by rusty-colored spots on the upper surface of the leaves.
Both diseases cause the leaves to wither and die, and can be prevented by avoiding overcrowding of plants, avoiding overhead watering, and providing adequate air circulation.
Yarrow is also vulnerable to insect pests, including aphids, caterpillars, and spider mites.
Aphids are small, soft-bodied insects that suck the sap from the leaves, which can cause them to yellow and curl.
Caterpillars can defoliate entire plants, while spider mites cause tiny yellow spots on the leaves.
To control these pests, it is important to inspect plants regularly and remove any insects that are present. Chemical insecticides can also be used, but should only be applied as a last resort.
Finally, yarrow can be affected by root rot, which is caused by a fungus that lives in the soil.
Symptoms of root rot include yellowing leaves, wilting, and stunted growth.
To prevent and control root rot, it is important to plant yarrow in well-drained soil and avoid overwatering. Mulching can also help to improve drainage and reduce the risk of root rot.
How to propagate yarrow ?

Plant Your Yarrow: If you're planting in a pot, fill the container with soil and lightly tamp it down. If you're planting in the ground, dig a hole twice as wide and just as deep as the root ball of the plant. Place the plant in the hole and fill in the soil around it. Water the area to settle the soil and give the plant a good start.
Water and Fertilize: Yarrow needs regular watering and fertilizing to thrive. Water the soil once a week, and fertilize every few weeks with a balanced, slow-release fertilizer.
