March is the perfect time to start pruning your perennials in Zone 1, preparing your garden for the growing season ahead. Proper pruning encourages healthy growth, improves flowering, and maintains the overall health of your plants. Here are the top 10 perennials to prune this March in Zone 1.

1. Peony (Paeonia)

Peonies benefit from early spring pruning. Remove any dead or damaged stems and cut back to just above the new buds. This promotes vigorous growth and abundant blooms.

2. Iris

Trim back iris foliage to about 2-3 inches above the ground. Clear away old leaves to prevent disease and encourage fresh, healthy growth.

3. Daylilies (Hemerocallis)

Remove any dead or yellowing leaves and cut back to the base. This helps promote new growth and improves the plant’s appearance.

4. Coneflower (Echinacea)

Cut back the old flower stalks to just above the basal leaves. This encourages healthy new growth and more vibrant flowers later in the season.

5. Black-eyed Susan (Rudbeckia)

Remove any dead or damaged stems and cut back to the base. Pruning in early spring helps prevent disease and promotes lush foliage.

6. Phlox

Prune back any dead or damaged stems and cut to the ground if necessary. This encourages fresh growth and vibrant flowers.

7. Sedum (Stonecrop)

Remove faded flower heads and trim back leggy stems. This helps maintain a compact shape and promotes healthy growth.

8. Shasta Daisy (Leucanthemum)

Cut back any dead or damaged foliage and remove spent flower stalks. Early pruning encourages a full, healthy bloom later in the season.

9. Astilbe

Remove old, brown flower stalks and trim back any damaged foliage. This revitalizes the plant for the upcoming growing season.

10. Lavender

Trim back the woody stems to promote bushier growth. Avoid cutting into old wood to prevent damage, and shape the plant for optimal flowering.

Conclusion

Pruning these perennials in early spring in Zone 1 will set the stage for a vibrant and healthy garden. Remember to use clean, sharp tools and always remove dead or damaged growth to keep your plants thriving throughout the season.
