How to Prune Back Cornus Stems

Pruning back Cornus stems is a common practice to maintain the stem’s vibrant colour and promote new growth. Here are the steps to follow:

1. Choose the right time: The best time to prune Cornus stems is in late winter or early spring when the plant is still dormant. Avoid pruning in late fall or during the growing season as it may damage the plant.
2. Gather the tools: You’ll need a pair of sharp pruning shears or loppers, gardening gloves, and disinfectant spray or alcohol to sterilize your tools.
3. Identify the stems to prune: Look for the oldest and most discoloured stems, which will have less vibrant colour than the newer growth. You can also prune any dead, damaged, or diseased stems.
4. Cut the stems: Using your pruning shears or loppers, make a clean cut at a 45-degree angle, about ¼ inch above a bud or node. Cut the stem close to the ground or to where you want to encourage new growth.
5. Dispose of the cuttings: Collect the cuttings and dispose of them properly to prevent the spread of disease.
6. Sterilize your tools: After pruning, spray your pruning tools with disinfectant spray or wipe them down with alcohol to avoid spreading any diseases to other plants.
7. Monitor the plant: Keep an eye on the plant and remove any new growth that is not showing the desired colour or growth habit.

Following these steps will help you prune your Cornus stems properly, promoting healthy growth and maintaining their vibrant colour.
