What Is the Ideal Temperature Range for Silvery yarrow?

Ideal Temperature: 60 ~ 75℉

Achillea clavennae thrives best in a temperature range between 60°F and 75°F. These conditions mimic the plant's natural habitat in mountainous regions where temperatures and conditions are moderate. Consistent temperatures within this range ensure optimal growth, flowering, and overall plant health.

What Soil is Best for Silvery yarrow?

Soil type: Calcareous soil, Sandy soil

Soil PH: 6.5 ~ 7.5

Achillea clavennae thrives in well-drained soil that prevents waterlogging, ensuring the roots do not rot. This facilitates proper aeration and helps the plant to absorb nutrients effectively, promoting robust growth and vibrant blooms. A unique characteristic of Achillea clavennae is its ability to thrive in nutrient-poor soils. This minimizes the need for heavy fertilization, reflecting its adaptation to rocky alpine environments. Such conditions encourage the plant's natural resilience and hardiness. Achillea clavennae prefers a soil pH ranging from 6.5 to 7.5, favoring environments that are neutral to slightly alkaline. This pH range suits its natural habitat, supporting optimal enzymatic activity and nutrient absorption.

How to Fertilize Silvery yarrow?

Fertilizer type: Balanced

Achillea clavennae, known for its delightful blooms, should be fertilized sparingly to avoid overwhelming its natural resilience. Liquid fertilizers should be diluted to half-strength before application, ensuring the plant receives balanced nutrients without the risk of nutrient burn. For slow-release fertilizers, a thin layer around the plant's base suffices, as it gradually supplies nutrients over time.

How to Prune Silvery yarrow?

Pruning Time: Spring, Summer

Before you start pruning, make sure you have clean, sharp pruning shears to ensure smooth cuts. Disinfect the blades with alcohol or bleach solution to prevent disease transmission. Identify and remove any dead, damaged, or diseased stems by cutting them back to healthy tissue. This not only tidies the plant but helps in preventing parasitic infections. Trim back stems to encourage bushier growth. Focus on maintaining a neat and compact shape, cutting just above a pair of leaves to promote branching and a fuller appearance.

How to Propagate Silvery yarrow plant?

Propagate Time: Spring, Early spring, Late spring

Place seeds on the surface of a good quality seed compost. Lightly cover with compost or vermiculite. Keep at 15-20°C until germination, which usually takes 14-21 days.

Use a sharp knife to cut a 4-6 inch length from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone to stimulate root growth.

Carefully dig up the plant and gently separate clumps into smaller sections, ensuring each division has roots attached. Replant in well-prepared soil and water immediately to establish contact with the soil.

How to Repot Silvery yarrow plant?

Repotting frequency: Every 2-3 years

Look for signs like roots growing through the drainage holes, water passing through too quickly, or visibly stunted plant growth. These indicators suggest that it's time to repot your Achillea clavennae to encourage healthy development.

Select a pot that is one size larger than the current one, with good drainage holes at the bottom. This ensures proper drainage, prevents waterlogging and root rot, and gives the roots room to spread and grow.

Pick a well-draining loamy soil mix, preferably with some added grit or sand. This replicates the plant's natural environment, prevents water retention, and helps maintain healthy root oxygenation.
