How Plant
Planting in the Garden:
- Choose a location in part shade with moist, rich soil.
- Prepare the bed by turning the soil under to a depth of 6-12, inches removing any debris, and lightly raking as level as possible.
- The addition of organic matter (leaf mold, compost, well-rotted manure) benefits all gardens and is essential in recently constructed neighborhoods.
- Dig a hole deep and wide enough to accommodate the bare root.
- Set the plant such that the crown is at or just slightly below the ground level. Allow roots to fan out from the crown at around a 45 degree angle. Roots should spread out separately, like stretched fingers, from the crown, and not bunch up. It may be helpful to build a cone-shaped mound of soil in the bottom of the hole and spread the roots around it. It is important to set the roots such that the crown is roughly level with the ground.
- Cover the roots with soil and tamp down firmly to get rid of air pockets. Fill the soil to just below the crown, where the top growth and leaves will emerge. Make sure all the roots under the crown are in good contact with the soil.
- Water well to fully saturate the roots and soil.
- Wait until new growth starts to appear before applying a layer of mulch.
How to Grow
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination.
- Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
- Careful watering is essential in getting perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry. One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.
- Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.
- After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer, as higher rates may encourage root rots.
- “Deadhead”, remove spent flower heads to encourage continuous flowering and prevent seed development.
- Remove and discard foliage after a hard frost in fall.
- Divide the clumps to keep astrantia under control as these plants spread quickly.
Growing Tips
- Many gardeners do not cut back perennial flower seed heads in the fall, but wait until early spring before the new foliage appears. This provides food for wildlife over the winter.
- Astrantia makes a great cut flower, fresh or dried.
- Astrantia will naturalize under trees and also makes a nice addition to perennial borders. It combines well with ornamental grasses, ferns, astilbes and irises.
