How to Prune Wild angelica?

(Angelica sylvestris)

Wild angelica, also known as Trumpet keck

Characterized by its towering stems and umbel flowers, wild angelica thrives with minimal pruning. Deadhead spent flowers to encourage reblooming and cut back foliage in late autumn. Optimal pruning occurs post-flowering in summer or early spring before new growth. Pruning controls size, promotes plant health, and prevents self-seeding. Sharp, clean tools are paramount to prevent disease.

What Are the Benefits of Pruning Wild Angelica?

Pruning wild angelica encourages vigorous growth, allowing for a more robust plant. It helps maintain the desired shape, ensuring wild angelica remains aesthetically pleasing and well-managed within the landscape.

What Is the Best Time for Pruning Wild Angelica?

Spring

Summer

Pruning wild angelica during late spring and early summer aligns with the post-flowering period, which is typically after this perennial has bloomed. Trimming in late spring allows gardeners to shape the plant and remove any spent flowers, which encourages a second bloom and healthy growth. Early summer pruning ensures that the removal of any dead or diseased stems takes place before wild angelica sets seed, promoting vigorous growth and preventing self-seeding that might lead to unwanted spread. During these seasons, wild angelica's growth is active, giving the plant ample time to heal from cuts and generate new growth before entering dormancy in the colder months. Pruning in these seasons also helps maintain the plant structure, manage size, and ensure optimal air circulation, which reduces the risk of fungal infections. Gardeners should always use clean, sharp tools to make precise cuts and minimize stress to wild angelica.

What Tools Do I Need to Prune Wild Angelica?

Bypass Pruners

These pruners make clean cuts that heal quickly, which is ideal for wild angelica because it has relatively soft stems. They are suitable for cutting stems up to around 3/4 inch in diameter.

Gardening Gloves

Handling wild angelica may expose the gardener to its sap, which can be irritating to the skin. Gloves also offer protection from thorns and rough foliage while pruning.

Long-Handled Loppers

In case wild angelica's stems are thicker or if they are hard to reach, loppers provide the extra leverage needed to make clean cuts without damaging the plant.

Pruning Saw

For mature wild angelica with woody stems that are too thick for pruners or loppers, a saw will be necessary. It allows for precision cutting of thicker branches.

Sharpening Tool

Regularly sharpening the blades of pruners and loppers ensures clean cuts, reduces the effort required to prune, and minimizes the risk of disease for wild angelica.

How to Prune Wild Angelica

Sanitization

Before pruning wild angelica, sterilize the cutting tools with alcohol or bleach solution to prevent disease spread.

Removal of diseased leaves

Identify and gently remove any diseased leaves from wild angelica by cutting them at the base where they meet the stem, taking care not to damage the main stem.

Removal of withered leaves

Cut away withered leaves from wild angelica at their base as well, as they are no longer beneficial to the plant and may harbor pests or diseases.

Removal of diseased stems

Locate and prune out diseased stems on wild angelica by making clean cuts above healthy buds or lateral branches to encourage good airflow and new growth.

Cleanup

After pruning, remove all the diseased or dead material from the area around wild angelica to prevent reinfection or attraction of pests.

Common Pruning Mistakes with Wild Angelica

Overpruning

Removing too much foliage from wild angelica can stress the plant, leading to weak growth or even plant death. It's essential to be cautious and prune no more than one-third of the plant at a time.

Improper cut location

Cutting too far from a node or bud, or too close to it, can result in poor regrowth or damage to the remaining stem. Always aim to make cuts just above nodes or buds.

Using dull tools

Dull pruning tools can cause jagged cuts that are more susceptible to disease and pests. Sharp, clean tools make healthier cuts for wild angelica.

Pruning in flower

Cutting back wild angelica while it is in bloom can remove the season's flowers and potential seeds, which may be important for self-seeding or providing food for wildlife.

Ignoring plant shape

Pruning without consideration of the natural shape of wild angelica can result in an unattractive, unbalanced appearance. It is important to maintain the plant's natural form.

Common Pruning Tips for Wild Angelica

Clean cuts

Ensure that all cuts are clean and at a 45-degree angle to prevent water accumulation and minimize the risk of disease.

After flowering

Prune wild angelica after flowering to shape the plant and remove spent flower heads, which encourages new growth and potentially more flowering in the next season.

Selective pruning

Thin out crowded stems to improve air circulation, which can help prevent disease by allowing more light to reach the inner parts of wild angelica.

Cut to outer buds

When making cuts, direct growth outward by cutting just above outward-facing buds. This allows for a more open, naturally shaped wild angelica.

Sanitize tools

Before and after pruning wild angelica, sanitize pruning tools to prevent the spread of disease from plant to plant.
