Hello fellow garden enthusiasts! We're the Hedge Cutting Staffordshire team, a professional gardener from Staffordshire, and today I'll be sharing my insights on summer pruning of cornus. Known for their vibrant winter stems, cornus (or dogwoods) benefit greatly from a mid-season tidy-up to ensure healthy growth and stunning displays.

Quick Answer

For summer pruning of cornus, focus on removing dead or crossing stems, and cut back about a third of the older growth to encourage new, colourful shoots.

Why Prune Cornus in Summer?

Summer pruning of cornus is essential to maintain their health and enhance their appearance. During this period, the plant is in its growth phase, allowing it to recover quickly and produce vigorous new shoots.

  • Encourages vibrant winter stem colour
  • Promotes dense growth
  • Removes dead or diseased wood

When to Prune Cornus

In the UK, the best time to prune cornus is between late June and early August. This timing ensures the plant has enough time to produce new growth before the cold sets in.

Month Task Notes
June Start pruning Focus on dead wood
July Continue pruning Thin out crowded areas
August Finish pruning Encourage new growth

How to Prune Cornus

Tools You'll Need

Before you start, make sure you have the right tools on hand: a pair of sharp secateurs, loppers for thicker branches, and gloves to protect your hands.

Step-by-Step Guide

Start by removing any dead, damaged, or diseased wood. Next, look for stems that are crossing each other and trim them back to prevent rubbing and damage. Finally, cut back about a third of the older stems to ground level to encourage new, vibrant growth.

Tips for Success

  • Make clean cuts to prevent disease
  • Prune on a dry day to reduce the risk of infection
  • Dispose of pruned material to avoid pests

Frequently Asked Questions

Can I prune cornus in winter?

Yes, winter is also a good time for hard pruning, especially if you want to encourage the brightest stem colours.

What if I prune too much?

Don't worry, cornus is quite resilient. It will usually bounce back with new growth, although it might take a season to fully recover.

How can I tell if a stem is dead?

Bend a small section of the stem; if it snaps easily and is dry inside, it's likely dead.
