When to plant
Plant Dicentra crowns in early spring as growth begins, or in autumn while the soil is still warm. Spring planting is ideal in colder regions; autumn planting works well where winters are mild.
Where to plant
Choose a partially shaded to fully shaded spot. Dicentra thrives in woodland borders, under trees, along north-facing fences and in any cool, sheltered location with dappled light. Avoid hot, exposed sun, as the foliage may scorch or die back early.
Preparing the soil
Loosen the soil to 20–25 cm and enrich it with compost, leaf mould or other organic matter. Dicentra prefers well-drained, humus-rich, consistently moist soil. Improve heavy clay with grit and compost; enrich sandy soil with additional organic matter.
Preparing the crowns
If planting bare-root crowns, soak them in lukewarm water for 20–30 minutes to rehydrate the roots. For potted plants, water well and gently loosen the root ball to encourage quick establishment.
Planting the crowns
Plant the crown so the top sits 2–3 cm below the soil surface. Space plants 40–50 cm apart to allow room for their arching stems and mature size. Firm the soil gently and water thoroughly.
After planting
Keep the soil evenly moist while the plants establish, but avoid waterlogging. A mulch of leaf mould or compost helps retain moisture and keeps the soil cool.
During growth
Water during dry periods, especially in spring and early summer. Remove spent blooms to keep the plant tidy. In warm climates Dicentra may naturally go dormant in midsummer — allow this to happen naturally.
After flowering
Cut back yellowing foliage once it collapses. Mark the planting location, as the crown will disappear during dormancy. Refresh mulch in autumn to support new growth in the following spring.
Extra tips
Dicentra pairs beautifully with ferns, hostas and pulmonarias in shade gardens. Avoid disturbing mature crowns as they dislike being moved or divided. Once settled, they can thrive for many years with minimal attention.
