PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring Planting: The ideal time to plant Epipactis palustris is in spring. This allows the roots to establish before the active growing season begins, promoting healthy growth and vibrant flowers.
Autumn Planting: Planting in early autumn ensures the plant can settle before dormancy, encouraging strong growth in the following year.
Site Selection
Sunlight: Epipactis palustris thrives in full sun or light shade. Select a location that receives at least 4–6 hours of sunlight daily to maximise flower production.
Soil: This orchid performs best in damp, boggy soil or along pond margins. Ensure the soil is consistently moist but well-drained. Chalky or nutrient-rich soils are particularly well-suited for Epipactis palustris, as long as waterlogging is avoided.
Planting Instructions
Prepare the Planting Area: Choose a damp, nutrient-rich site. Clear weeds and loosen the soil to ensure good root penetration.
Dig the Hole: Create a hole twice the width of the root ball and slightly deeper than the plant’s roots. This provides ample space for root growth.
Amend the Soil: Mix organic matter, such as compost or leaf mould, into the soil to enhance fertility and drainage.
Planting: Place the root ball into the hole, ensuring the crown of the plant sits level with the soil surface. Backfill gently, firming the soil around the base to eliminate air pockets.
Watering: Water thoroughly after planting to help settle the soil and establish good root contact.
Watering Requirements
Active Growth Season: Epipactis palustris requires consistently moist soil during the growing season. Water regularly, especially during dry spells, but avoid letting the soil become waterlogged.
Dormant Season: During the dormant winter months, reduce watering. Only water if the soil dries out completely, as excessive moisture during dormancy can harm the roots.
Feeding
Spring Fertilisation: Apply a balanced, slow-release fertiliser in early spring to encourage robust growth and flower development.
Mid-Summer Boost: A light application of liquid fertiliser in mid-summer can help sustain the plant’s vigour and prolong flowering.
Pruning and Maintenance
Deadheading: Remove spent flower spikes to encourage further blooming and maintain a tidy appearance.
End-of-Season Care: In late autumn, after flowering has finished, cut back the plant to just above ground level. This prepares Epipactis palustris for winter dormancy.
Mulching
Spring Mulching: Apply a 2–3 cm layer of organic mulch, such as bark chips or well-rotted compost, in spring. This helps retain moisture, suppress weeds, and regulate soil temperature.
Winter Protection: Mulching in late autumn can also insulate the roots from cold weather, preventing frost damage.
Supporting the Plant
Staking: In exposed or windy areas, consider staking the flower spikes of Epipactis palustris to prevent breakage. Use soft ties to secure the stems without damaging them.
