Astrantia ‘Burgundy Manor’

Astrantia ‘Burgundy Manor’ is an elegant, long-flowering perennial prized for its deep burgundy-red pincushion flowers held above finely divided green foliage. It is ideal for providing colour and interest from late spring through summer.

Providing seasonal care is essential to ensure healthy growth, repeat flowering, and long-term performance. Below is a complete seasonal care guide for Astrantia ‘Burgundy Manor’ throughout the year.

Spring

Pruning and Maintenance

In early spring, remove any dead or damaged foliage from the base of the plant using clean, sharp secateurs. This encourages fresh new growth and keeps the plant tidy as the growing season begins.

Feed

Apply a balanced, slow-release fertiliser formulated for flowering perennials in spring as new growth appears. This supports healthy development and encourages abundant flowering.

Dividing (if necessary)

Every 3–4 years, Astrantia can be divided in spring if clumps become overcrowded or flowering declines. Lift the plant carefully, divide into sections, and replant into moisture-retentive, well-drained soil.

.

Begin regular watering as temperatures rise, keeping the soil consistently moist during establishment.

Summer

Pruning and Maintenance

Deadhead spent flowers regularly by cutting stems back to the base or a healthy set of leaves. This encourages repeat flowering and prolongs the blooming period.

Mulching

Apply a 2 to 3-inch layer of organic mulch around the base of the plant to retain moisture, suppress weeds, and regulate soil temperature, particularly in warm weather.

Watering

Astrantia ‘Burgundy Manor’ prefers evenly moist soil and may wilt in dry conditions. Water regularly during dry spells, especially in full sun, and avoid allowing the soil to dry out completely.

Autumn

Pruning and Maintenance

As flowering slows, you can lightly tidy the plant by removing spent stems and damaged foliage. Leave the main crown intact to protect the plant over winter.

Protection from frost

Refresh the mulch around the base of the plant to provide insulation as temperatures begin to fall.

Winter

Protection from frost

Astrantia ‘Burgundy Manor’ is fully hardy and generally requires little winter protection. A layer of mulch helps protect the crown from severe frost and winter wet.

Pest and disease prevention

Pests and diseases are minimal during winter, but inspect occasionally for signs of rot caused by waterlogged soil and remove any affected growth promptly.

Plant SOS

Wilting leaves – A sign of dry soil or heat stress. Increase watering and mulch well.

Few or no flowers – A sign of too much shade or overcrowding. Improve light levels and divide clumps if necessary.

Yellowing leaves – A sign of poor drainage or nutrient deficiency. Improve soil conditions and apply feed in spring.

Short flowering period – A sign that deadheading is needed. Remove spent flowers regularly to encourage repeat blooms.

Poor growth – A sign of dry or compacted soil. Improve soil structure and maintain consistent moisture.

Holes in leaves – A sign of slug and snail damage. Use Slug and Snail repellent or Slug and Snail control.
