Planting & Care

Planting and caring for the Amazing Daisies® 'Marshmallow' Shasta Daisy (Leucanthemum superbum) is straightforward, making it an excellent choice for both novice and experienced gardeners. Here's a guide to help you get the best out of this beautiful perennial:

Planting Instructions:

  • Timing: Plant in spring or early fall to allow the plant time to establish roots before the extremes of summer heat or winter cold.
  • Location: Choose a location that receives full sun to part sun, meaning at least 6 hours of direct sunlight daily. Afternoon shade can be beneficial in hotter climates.
  • Soil: This plant prefers well-drained soil. It tolerates a range of soil types, from average to fertile, and can grow in both acidic and neutral pH levels.
  • Spacing: Space plants 20 to 22 inches apart to allow for proper air circulation and growth expansion.
  • Planting: Dig a hole as deep and twice as wide as the root ball. Gently remove the plant from its container, loosen the roots, and place it in the hole. Fill in with soil, and press firmly around the base of the plant. Water thoroughly after planting.

Care Instructions:

  • Watering: Water regularly to keep the soil moist, especially during dry spells, but avoid overwatering. Once established, the 'Marshmallow' Shasta Daisy is somewhat drought tolerant but may need more frequent watering in extreme heat or if planted in containers.
  • Mulching: Apply a layer of mulch around the base of the plant to help retain soil moisture, reduce weed competition, and protect the roots in colder climates.
  • Fertilizing: Feed with a general-purpose garden fertilizer in early spring and again in mid-summer to support vigorous growth and blooming. Avoid over-fertilization, which can lead to excessive foliage at the expense of flowers.
  • Pruning: Deadhead spent flowers regularly to encourage continuous blooming throughout the summer. In late fall, after flowering has finished, cut the plant back to the ground to help promote healthy growth for the next season.
  • Overwintering: In zones 5a to 9b, the 'Marshmallow' Shasta Daisy should overwinter well with minimal care. In the cooler parts of its range, a layer of mulch can provide extra insulation against freezing temperatures.

Additional Tips:

  • Pest and Disease Management: This plant is generally resistant to pests and diseases. However, keep an eye out for common issues like aphids or powdery mildew and treat accordingly.
  • Division: To maintain vigor and prevent overcrowding, divide the plants every 2-3 years in early spring or fall. This will also give you more plants to expand your garden or share with friends.

By following these planting and care instructions, your Amazing Daisies® 'Marshmallow' Shasta Daisy will thrive, bringing beauty and life to your garden with its stunning white blooms and lush foliage.
