How to Prune Goat's-rue?

(Galega officinalis)

Goat's-rue, also known as Galega, Italian fitch

This leguminous herbaceous perennial is notable for its medicinal qualities and pea-like flowers. To promote bushier growth and control size in goat's-rue, pruning should involve cutting back by a third after the initial flowering in early summer. Repeat light trimming can occur throughout summer as flowers fade to encourage further blooms. Avoid fall pruning to prevent new growth susceptible to frost. Regular removal of damaged or diseased stems is vital to maintain plant health and vigor.

What Are the Benefits of Pruning Goat's-rue?

Pruning goat's-rue encourages prolific blooming, maintains a desired form, and stimulates robust growth, ensuring a visually appealing and healthy plant.

What Is the Best Time for Pruning Goat's-rue?

Spring

Summer

Autumn

Spring pruning aligns with the onset of goat's-rue's active growth period, encouraging a robust flush of new growth as energy stores are directed into recovery from the pruning cuts. Early Summer is ideal for trimming back any overly vigorous growth or for shaping the plant, ensuring that these activities do not interfere with the main flowering period. Late Fall pruning is beneficial for overall plant health and preparation for dormancy; it involves removing any dead or diseased wood and helps prevent potential pest and disease issues over the winter.

What Tools Do I Need to Prune Goat's-rue?

Bypass Pruners

These are suitable for cutting through live stems of goat's-rue, offering a clean and precise cut without damaging the plant's tissues. They can handle stems up to about 1/2 inch in diameter, which is likely the case for goat's-rue.

Hand Shears

Hand shears are ideal for shaping and thinning the foliage of goat's-rue. Their long blades make it easy to create a uniform appearance while promoting healthy growth and airflow within the plant.

Loppers

If goat's-rue has matured and has thicker branches that bypass pruners can't handle, loppers would be the next tool of choice. With their long handles, they can cut through branches up to 1 1/2 inches in diameter and allow for reaching into the plant without causing damage to the surrounding growth.

Pruning Saw

For the thickest branches of goat's-rue that are over 1 1/2 inches in diameter, a pruning saw might be necessary. It allows for larger cuts without exerting too much effort, safeguarding the gardener from injury and the plant from jagged cuts.

How to Prune Goat's-rue

Identify diseased parts

Inspect goat's-rue thoroughly to identify all diseased leaves, as these must be removed to prevent further infection.

Clean cut

Use sterilized pruning shears to cleanly cut off diseased and withered leaves at the base of the stem to avoid leaving stubs which can decay.

Deadhead

Pinch or snip off withered flowers of goat's-rue at the base of their stems to promote new growth and prevent seeding if not required.

Dispose

Collect and dispose of all removed plant material far from the garden to prevent the spread of diseases or pests.

Sanitize

Clean and sterilize your pruning tools after trimming goat's-rue to avoid transferring pathogens to other plants or the next pruning session.

Common Pruning Mistakes with Goat's-rue

Overpruning

Removing too much foliage from goat's-rue at once can stress the plant, leading to reduced vigor and sparse flowering.

Neglecting deadheading

Goat's-rue benefits from the removal of spent flowers to encourage further blooming, and neglecting this task can result in fewer flowers and potential self-seeding.

Ignoring disease protocol

Using unsterilized tools or pruning when goat's-rue is wet can spread diseases. Always sanitize pruning tools and prune in dry conditions.

Improper cut placement

Cutting too close to or too far from the main stem can harm goat's-rue. Make clean cuts at a 45-degree angle just above a bud or branching point.

Common Pruning Tips for Goat's-rue

Maintain plant shape

Prune goat's-rue to maintain its natural shape, focusing on creating an open center for sunlight penetration and air circulation, which promotes healthy growth.

Removal of dead or damaged stems

Regularly inspect goat's-rue and remove any dead, damaged, or diseased stems to prevent the spread of pathogens and encourage new growth.

Encourage new growth

By selectively pruning the older stems of goat's-rue, gardeners can stimulate the growth of new, more vigorous stems that will produce abundant blooms.

Post-flowering pruning

Once goat's-rue has finished blooming, cut back the flower spikes to promote a potential second bloom and to keep the plant tidy.
