When to Prune Red Osier Dogwood
The best time to prune red osier dogwood is in late winter or early spring, before new growth begins. This allows you to remove dead or damaged branches while the plant is dormant.
How to Prune Red Osier Dogwood
Step 1: Gather Your Tools
You will need the following tools for pruning red osier dogwood:
- Sharp pruning shears
- Loppers for thicker branches
- Pruning saw for large branches
- Gloves (optional)
Step 2: Remove Dead or Damaged Branches
Begin by removing any dead, diseased, or broken branches. These branches are usually brown or black in color and may have loose bark. Cut them back to the main stem or to a healthy lateral branch.
Step 3: Prune Old Branches
Once you have removed the dead or damaged branches, identify and prune any old or overgrown branches. These branches are typically thicker and have fewer leaves. Cut them back to a lateral branch or to the ground.
Step 4: Thin Out Dense Growth
If the red osier dogwood is growing too densely, you can thin out the branches to improve air circulation. Remove any branches that are crossing or rubbing against each other.
Step 5: Shape the Plant
After you have removed the dead, old, and dense branches, you can begin to shape the plant. Use your pruning shears or loppers to cut back branches to the desired length or shape.
Step 6: Rejuvenate Old Plants
If your red osier dogwood is old and overgrown, you can rejuvenate it by cutting it back hard. Cut all the branches to within a few inches of the ground. This will stimulate new growth and give the plant a fresh start.
Step 7: Clean Up
After pruning, clean up any debris and dispose of it properly. You can compost small branches and twigs, but larger branches should be disposed of in the yard waste.
Tips for Pruning Red Osier Dogwood
- Always use sharp pruning tools to make clean cuts.
- Cut branches at a slight angle to prevent water from collecting on the cut surface.
- Do not prune more than one-third of the plant’s total growth at a time.
- Avoid pruning in the summer or fall, as this can encourage disease and insect problems.
