Cutting Back Vinca for Winter: A Comprehensive Guide

As winter approaches, many gardeners start preparing their gardens and landscapes for the cold months ahead. One important winter preparation task is cutting back vinca plants. Vinca, also known as periwinkle, is a popular ground cover plant that blooms beautifully in spring and summer. However, to ensure your vinca plants survive the winter and return vigorously in spring, proper cutting back is essential. In this comprehensive guide, we’ll cover when, how, and why you should cut back vinca for winter.

When to Cut Back Vinca for Winter

Timing is crucial when cutting back vinca for winter preparation, Cutting too early or too late can negatively impact the plant’s winter survival and spring regrowth Here are some tips on ideal timing

• Wait until after the first frost hits This allows you to assess and remove any frost damaged foliage,

• Late fall before the ground freezes is ideal. Mid October to mid November is recommended for most regions.

• Don’t cut back too early in fall or you may get regrowth that is damaged by subsequent frosts.

• Cutting back too late in winter leaves plants vulnerable to damage from heavy snow or ice.

How to Cut Back Vinca for Winter

Cutting back vinca properly is vital for the plant’s health. Follow these steps:

1. Gather Necessary Tools

Secateurs, loppers, hedge trimmers – make sure all tools are clean, sharp, and disinfected. Dull tools tear rather than cut cleanly.

2. Assess and Remove Dead Foliage

Check for and remove any dead, damaged, or diseased leaves and stems. This prevents disease spread.

3. Cut Back Stems

Trim stems back to around 1/3 to 1/2 of their height. This reduces transpiration over winter, conserving moisture and energy.

4. Shape as Desired

Prune any remaining stems and foliage to maintain a shapely form. Bushy, mounded forms or formal topiaries can be shaped.

5. Make Final Checks

Do a final check for any remaining dead foliage to remove. Clean up all cut debris when done.

Why Cut Back Vinca for Winter

Cutting back vinca in late fall provides several benefits:

• Prevents damage from heavy snow and ice accumulation which can break unsupported stems.

• Removes dead and damaged foliage to prevent disease spread.

• Promotes more vigorous, compact regrowth in spring.

• Maintains a tidy, attractive form over winter months.

• Reduces moisture loss and conserves energy reserves over winter.

Post-Pruning Care

After cutting back vinca for winter, provide care to help the plants recover:

• Water thoroughly after pruning to reduce transplant shock.

• Apply a balanced fertilizer to fuel regrowth. Avoid high nitrogen types.

• Mulch around plants to insulate roots and reduce weeds.

• Check for signs of stress and diseases. Address issues promptly.

• Protect from harsh winter winds and freezing. Cover or move containers in doors.

Continued monitoring and care will ensure your vinca stays healthy through winter, ready for vigorous regrowth when spring arrives.

Common Mistakes to Avoid

When cutting back vinca, it’s important to avoid these common mistakes:

• Pruning too severely – only remove up to 50% of growth.

• Pruning too late in fall after ground has frozen.

• Leaving damaged, diseased foliage that can spread infection.

• Cutting way early in fall, stimulating new growth subject to frost damage.

• Not disinfecting tools between plants or cuts, spreading disease.

• Not making clean cuts just above leaf nodes.

Key Takeaways

• Cut back vinca in late fall, after first frosts hit, before ground freezes.

• Remove dead foliage, cut stems back by 1/3 to 1/2 of height.

• Pruning prevents winter damage, promotes spring regrowth.

• Avoid over pruning, late pruning, and not disinfecting tools.

• Provide proper care after cutting back to help recovery.

Cutting back vinca properly in late fall prepares the plants for winter and promotes lush, vigorous regrowth in spring. Follow these tips for successfully cutting back vinca for winter.

To overwinter vinca (also known as periwinkle), you can either leave it in the ground with a thick layer of mulch or bring it indoors as a houseplant.
