Design Tips & Care Guide
🌿 Planting & Spacing
Most full sun perennials thrive in well-drained soil. Space plants 18–24 inches apart to allow for good air circulation, which helps prevent fungal diseases. Amend soil with compost at planting time for best results.
💧 Water & Fertilizer
Water deeply once a week during dry spells, more often in extreme heat. Apply a balanced slow-release fertilizer in early spring. Many of these perennials are drought-tolerant once established, making them water-wise choices.
✂️ Maintenance Made Easy: Deadheading (removing spent flowers) encourages many perennials to rebloom. In late fall, cut back dead foliage after a few hard frosts. For zone 6, apply a 2–3 inch layer of mulch to protect roots over winter and retain moisture in summer.
