By following these care guidelines, your Achillea millefolium 'Summer Taffy' will not only grow but flourish, adding a splash of color and texture to your garden.

How to Plant Achillea millefolium 'Summer Taffy' 

Planting Achillea millefolium 'Summer Taffy', a captivating variety of Yarrow with its unique pinkish-red blooms, can bring a delightful splash of color to your garden landscape. Here's a comprehensive guide on how to plant and nurture Achillea millefolium 'Summer Taffy'.


When to Plant

  • Best Time: The optimal planting times are in the early spring or autumn. Achillea millefolium 'Summer Taffy' is cold-hardy, allowing for early spring planting as soon as the soil is workable, or in autumn before the onset of frost.

  • Zone Considerations: This plant flourishes in USDA zones 3-9. Depending on your specific zone, the ideal planting period may slightly adjust.

Selecting a Site

  • Sunlight: A location with full sun is essential, as Achillea millefolium 'Summer Taffy' requires at least 6 hours of direct sunlight daily for optimal growth.

  • Soil: Well-draining soil is crucial for health. The plant is susceptible to root rot in overly moist conditions. Enhance heavy or clay soils with sand or organic material to improve drainage.

Planting Steps

  • Soil Preparation: Loosen the soil to a depth of about 12-15 inches, integrating compost or aged manure to enrich the soil's nutrients.

  • Spacing: Space Achillea millefolium 'Summer Taffy' seedlings or plants approximately 18-24 inches apart to ensure sufficient air flow and minimize disease risk.

  • Planting Depth: Excavate a hole that is both as deep and twice as wide as the root ball. Place the plant in the hole so the root ball's top is level with the surrounding soil surface. Refill the hole with soil, firmly pressing around the roots.

  • Watering: After planting, water the area thoroughly. While Achillea millefolium 'Summer Taffy' is drought-tolerant once established, maintaining slight soil moisture aids in plant establishment.

  • Mulching: Apply a 2-inch layer of mulch around the plants to help retain soil moisture, moderate soil temperature, and reduce weed growth.

Ongoing Care

  • Watering: Regularly water the young plants until they are fully established. Mature specimens need minimal watering and can withstand drought conditions.

  • Fertilizing: Achillea millefolium 'Summer Taffy' requires minimal fertilization. Excessive nutrients can cause spindly growth and diminish blooming. Apply a balanced fertilizer lightly in spring if necessary.

  • Deadheading: To encourage additional blooming and prevent excessive self-seeding, remove faded flowers.

  • Division: To maintain vigor and prevent overcrowding, divide the plants every 3-4 years in either spring or autumn.

By adhering to these instructions, your Achillea millefolium 'Summer Taffy' will thrive, providing your garden with striking pinkish-red flowers from late spring through autumn.

Pests and Diseases

While Yarrow Terracota is relatively pest and disease resistant, it's important to be vigilant to ensure the health of your plants.

  • Watch out for aphids and spider mites; treat with insecticidal soap if necessary.

  • Fungal diseases like powdery mildew can occur in humid conditions; improve air circulation and reduce watering.

  • Regular inspection can prevent most issues before they become severe.

Feeding and Fertilizing

Feeding and fertilizing Achillea millefolium 'Summer Taffy' is an easy task, given the plant's resilience and minimal nutritional requirements. Nonetheless, proper nourishment can bolster its growth and enhance its blooming performance. Follow these tips to ensure your Achillea 'Summer Taffy' receives the right amount of nutrients.

General Guidelines

  • Low Fertilizer Needs: Achillea millefolium 'Summer Taffy' flourishes in soils ranging from moderate to poor fertility. Over-fertilization can lead to lush foliage at the expense of bloom production and increase the plant's vulnerability to diseases.

  • Soil Test: Conducting a soil test prior to fertilizer application is wise. This will reveal the existing nutrient levels in your soil and help determine whether your Achillea needs additional fertilization.

Fertilizing Schedule

  • Spring Application: Should your soil test suggest a need for nutrients, apply a light application of balanced, slow-release fertilizer as the plant resumes growth in early spring. Opt for a fertilizer with an N-P-K ratio (Nitrogen-Phosphorus-Potassium) of 10-10-10 or 20-20-20.

  • Avoid Over-fertilizing: Over-fertilizing is a common mistake that can result in spindly plants, weak stems, and diminished flowering. If your Achillea 'Summer Taffy' is thriving and flowering well, additional fertilizer may not be necessary.

Organic Alternatives

  • Compost and Manure: Enriching the soil with compost or aged manure can be a superior alternative to synthetic fertilizers. These organic options enhance soil texture, gradually release nutrients, and support robust plant development without the risk of over-fertilizing.

  • Mulching: A layer of organic mulch around your Achillea not only conserves soil moisture and deters weeds but also breaks down over time to slowly release nutrients back into the soil.

By following these feeding and fertilizing guidelines, your Achillea millefolium 'Summer Taffy' will be well-nourished, supporting its lush foliage and vibrant blooms throughout the growing season.

Seasonal Care

Caring for Agastache urticifolia 'Blue Fortune' throughout the different seasons involves specific practices to ensure the plants remain healthy, vibrant, and blooming profusely. Here's a seasonal care guide for Agastache urticifolia 'Blue Fortune' that will help you maintain your plants year-round.


Spring 

  • Cleanup: Begin with cleaning up any dead foliage and debris from around your plants to prevent disease and pests. Dividing: Early spring, before new growth starts, is an ideal time to divide mature plants (every 3-4 years) to maintain vigor and to propagate. This helps prevent overcrowding and promotes healthy growth. 

  • Planting: You can plant new Agastache urticifolia 'Blue Fortune' plants as soon as the soil is workable. Spring is a great time for planting to allow the root system to establish before the hot summer months. 

  • Mulching: Apply a thin layer of organic mulch to conserve moisture, regulate soil temperature, and suppress weeds. Avoid mulching too close to the stem to prevent rot. Watering: Begin regular watering if the spring is particularly dry, ensuring the soil is well-drained to prevent waterlogging.


Summer 

  • Watering: Agastache urticifolia 'Blue Fortune' is drought-tolerant but will benefit from watering during prolonged dry spells, especially newly planted ones that haven't fully established. 

  • Deadheading: Regularly remove spent flowers to encourage continuous blooming throughout the summer. Some varieties may rebloom if deadheaded. 

  • Monitoring: Keep an eye out for pests and diseases, although Agastache urticifolia 'Blue Fortune' is generally resistant to many common garden problems.


Fall 

  • Deadheading/Pruning: You can choose to leave some spent blooms on the plants in fall to provide winter interest and food for birds. Alternatively, trim the plants down to the ground after the first hard frost if you prefer tidiness. 

  • Mulching: Refresh the mulch layer after trimming the plants to protect the roots over the winter, especially in colder climates. Dividing: In addition to spring, early fall is also a good time to divide plants if you didn't do it in the spring. Ensure there's enough time for the plants to establish before the first frost.

  • Winter Protection: In very cold climates, additional mulch can be applied after the ground freezes to protect the plants from freeze-thaw cycles that can heave the roots out of the ground. 

  • Planning: Winter is an excellent time to assess your garden's performance over the past year and plan any changes or additions for the next season.


Year-Round Tips 

  • Fertilization: Agastache urticifolia 'Blue Fortune' generally does not require much fertilization, especially if planted in fertile soil. If necessary, a light application of a balanced fertilizer in early spring is sufficient. 

  • Soil Care: Ensure the soil remains well-drained; amend heavy clay soils with organic matter to improve drainage. 

  • Pest and Disease Management: While generally low-maintenance, be vigilant about potential problems such as aphids or powdery mildew, and treat as necessary.


By following this seasonal care guide, your Agastache urticifolia 'Blue Fortune' plants should thrive and produce beautiful blooms year after year, contributing to a vibrant and dynamic garden landscape.
