How to Grow Rodgersia
Rodgersia pinnata
Rodgersia is a bold, moisture-loving perennial with large palmate or pinnate leaves and plumes of pink or white flowers in early summer. Plant in damp, sheltered shade with humus-rich soil. Mulch generously in spring. Protect from wind which can shred the large leaves. Once established, it forms impressive architectural clumps.
Yearly Lifecycle
Care Essentials
Mulch with compost or well-rotted manure in spring. Rodgersia is a hungry plant in rich, damp soil — an annual mulch is usually sufficient.
Watch For
- Wind damage to large leaves (site in shelter)
- Slugs on emerging spring growth
- Drought stress — leaves will scorch and brown at edges

☀️ Light
Partial shade to full shade preferred
Rodgersia performs best in dappled or partial shade. It tolerates full shade but produces fewer flowers. Avoid hot afternoon sun, which scorches the large leaves.
💧 Watering
Keep soil consistently moist
Rodgersia is a moisture-loving plant and will not tolerate drought. Water regularly during dry spells and mulch heavily to retain soil moisture.
🌱 Fertilizing
Annual spring mulch is sufficient
A generous layer of well-rotted compost or leaf mould applied in spring provides all the nutrition needed. Avoid high-nitrogen feeds which promote soft, floppy growth.
✂️ Pruning
Cut back old foliage in late winter
Remove all dead and collapsed foliage in late winter or early spring before new growth emerges. Leave seedheads standing through winter for structural interest.
❄️ Overwintering
Hardy — no protection needed
Rodgersia is fully hardy in the UK and requires no winter protection. The crown is dormant underground and withstands hard frosts without damage.
Growing Tips
Site in moist shelter
Rodgersia needs reliably moist soil and protection from wind. A sheltered spot beside a pond or stream is ideal — dry or exposed sites cause leaf scorch and poor growth.
Bronze spring foliage is normal
The large leaves emerge bronze-tinted in spring before greening up. This is normal and part of the plant's seasonal display, not a sign of nutrient deficiency.
Mulch generously each spring
Apply a thick mulch of compost or leaf mould in early spring before the crown wakes up. This single action retains moisture and feeds the plant through the entire growing season.
Divide to rejuvenate
Large clumps can be divided in early spring every 4–5 years. Use a sharp spade to cut through the crown and replant sections with at least one bud each.
Pests & Diseases
Pest Slugs and Snails
Identification: Irregular holes in young leaves, slime trails on foliage and soil nearby.
- Apply wool pellets or sharp grit around the crown as a physical barrier.
- Use nematode treatments (Phasmarhabditis hermaphrodita) watered into the soil in spring.
- Apply ferric phosphate slug pellets around plants as per label directions.
Pest Vine Weevil
Identification: Notched leaf margins from adult beetles; sudden wilting or death of plant from larvae eating roots.
- Apply beneficial nematodes (Steinernema kraussei) to moist soil in late summer or early autumn.
- Check compost when repotting and remove C-shaped cream larvae by hand.
- Drench soil with a vine weevil killer containing acetamiprid or thiacloprid in autumn.
Disease Powdery Mildew Erysiphe spp.
Symptoms: White powdery coating on upper leaf surfaces, mostly in late summer on plants under drought stress.
Treatment: Remove affected leaves. Improve soil moisture with mulch and supplemental watering.
Prevention: Keep soil consistently moist. Avoid siting in dry or exposed positions.
Disease Crown Rot Phytophthora spp.
Symptoms: Soft, water-soaked crown tissue that collapses; foliage wilts and turns yellow or brown from the base.
Treatment: Improve drainage. Remove and destroy badly affected plants. Avoid overwatering.
Prevention: Never plant in waterlogged soil. Ensure mulch does not sit directly against the crown.
