Selecting the Right Location

Astrantia thrives in partial to full shade, making it an excellent choice for woodland gardens or areas with filtered sunlight. This plant does well with morning sun and afternoon shade, providing it protection from the intense midday sun.


Soil Preparation

Enhance the soil with organic matter before planting. Incorporate well-rotted compost or manure to improve soil fertility and structure. Aim for a slightly acidic to neutral soil pH between 6.0 and 7.0, as Astrantia prefers soils that are not too alkaline.


Planting Time

Optimal planting times are early spring or early autumn. This allows the plant to establish itself before the extremes of summer heat or winter cold, promoting a healthier start.


Planting Depth

When planting, dig a hole slightly larger than the root ball of the Astrantia plant. Position the plant so that the crown is level with the soil surface, preventing crown rot and encouraging healthy growth.



Keep the soil consistently moist, especially during the initial growing season when the plant is establishing its roots. While Astrantia becomes moderately drought-tolerant once established, regular watering is still beneficial, particularly during dry spells.



Apply a layer of organic mulch around the base of the plant. This helps retain soil moisture, suppress weeds, and regulate soil temperature, contributing to the overall health of the plant.



Use a balanced, slow-release fertiliser in spring to provide essential nutrients without promoting excessive growth. Avoid high-nitrogen fertilisers, as Astrantia tends to favour a balanced nutrient profile for optimal development.



Regular deadheading of spent flowers encourages continuous blooming throughout the growing season. In late autumn or early spring, cut back the entire plant to a few inches above the ground to rejuvenate the plant and maintain a tidy appearance.



Taller varieties of Astrantia may require staking or support to prevent stems from bending or flopping, particularly during periods of heavy rain or wind.


Pest and Disease Management

Astrantia is generally resistant to pests and diseases. Maintaining good garden hygiene is essential, ensuring proper air circulation around the plants to prevent the development of mildew, which can be a common issue in humid conditions.



Divide crowded clumps of Astrantia every 3-4 years to prevent overcrowding and maintain plant vigour. Early spring or autumn is the best time for division when the plant is not actively flowering.


Enjoy the Blooms

Astrantia produces intricate, pincushion-like flowers that attract pollinators such as bees and butterflies. Take the time to appreciate the unique beauty and delicate charm that Astrantia brings to your garden throughout the growing season. Observing and enjoying the blooms contribute to the overall satisfaction of cultivating this captivating perennial.

Now you have successfully planted your Astrantia. Ensure the continued health and vibrancy of your Masterwort with these aftercare tips:



Established Plants: Astrantia is moderately drought-tolerant once established. Water deeply and consistently during dry periods, allowing the soil to dry slightly between waterings.

Newly Planted: Provide extra attention to newly planted Astrantia. Keep the soil consistently moist during the first growing season to support root establishment.



Maintain a layer of organic mulch around the base of the plant. This helps retain soil moisture, suppress weeds, and regulate soil temperature. Refresh the mulch layer as needed.



Apply a balanced, slow-release fertiliser in spring when new growth emerges. Avoid excessive nitrogen, as Astrantia prefers a balanced nutrient profile. Follow package instructions for application rates.



Deadheading: Remove spent flowers regularly to encourage continuous blooming. This not only prolongs the flowering period but also promotes a neat appearance.

End of Season: In late autumn or early spring, cut back the entire plant to a few inches above the ground. This helps rejuvenate the plant and prepares it for the new growing season.



Tall varieties may benefit from staking or support. Install stakes early in the growing season to prevent stems from bending or flopping, especially during heavy rain or wind.


Pest and Disease Management:

Astrantia is generally resistant to pests and diseases. However, practice good garden hygiene by removing any debris around the plant to prevent potential issues. Ensure proper air circulation, especially in humid conditions.



Divide crowded clumps every 3-4 years to maintain plant vigour. Early spring or autumn is the best time for division when the plant is not actively flowering. Replant divisions in well-prepared soil.


Enjoy the Blooms:

Take time to appreciate the intricate, pincushion-like flowers that Astrantia produces. The unique beauty and delicate charm add a touch of elegance to your garden.



Regularly inspect your Astrantia for signs of stress, pests, or diseases. Address any issues promptly to ensure the continued health and vitality of your plants.
