Common Pruning Mistakes with Dahlia 'vancouver'

Improper Technique

One common mistake is using dull or dirty tools, which can cause jagged cuts and introduce disease. Always use sharp, clean pruning shears.

Pruning Too Much

Over-pruning can cause stress to dahlia 'Vancouver' and inhibit flowering. Avoid cutting back more than one-third of the plant at any one time.

Incorrect Timing

Pruning at the wrong stage of growth can stunt the plant's development. It's essential to prune dahlia 'Vancouver' at the right time to ensure healthy regrowth.

Ignoring Deadheading

Cutting Too Close

Cutting too close to the main stem can damage the plant's tissue, increasing the risk of disease and pest infestation.

Common Pruning Tips for Dahlia 'vancouver'

Use the Right Tools

Invest in high-quality pruning shears for clean cuts. Sterilize your tools before and after use to prevent the spread of disease.

Focus on Deadheading

Regularly remove spent flowers by cutting just above the next set of leaves or flowering stem. This encourages more blooms and prolongs the flowering season.

Prune for Shape

Trim dahlia 'Vancouver' to maintain a desirable shape, focusing on removing any straggly or overgrown stems. This promotes a fuller and more balanced appearance.

Remove Damaged Parts

Always prune out dead, diseased, or damaged stems to improve air circulation and reduce the risk of pest and disease problems.

Pinch for Bushier Growth

Pinching back the tips of young stems can encourage dahlia 'Vancouver' to become bushier and produce more blooms. Simply use your fingers to nip off the top 1-2 inches of growth.
