How to plant Polystichum
Polystichum are a diverse group of predominantly evergreen species. This is one of the largest of the Fern groups and often the easiest to grow. Polystichum are adaptable perennials enjoying light shade and moist, but well drained soil making them more easily placed in the garden than many moisture-loving ferns. The unfurling fronds make a fine feature as they arch outwards in spring, remaining intact throughout the winter months to provide year-round interest. These versatile ferns create a naturalistic feel, associating beautifully with other ferns and perennials in lightly shaded borders. They also cope well in containers.
How to plant
- Plant Polystichum in the spring from February to May.
- Soak the roots in water for 3-6 hours prior to planting. Pot into temporary 2 litre pots, using a good quality multi-purpose compost. Grow them on in a sheltered spot outside. They can be transplanted to their final positions after 6-8 weeks or once growth is well established.
- Plant the roots with the crown just at the soil surface.
- Although perfectly hardy, they prefer a sheltered spot, with protection from hard frosts and strong winds.
- Polystichum are a diverse groups that grow in a wide range of conditions but most will prefer a moist, well drained neutral to slightly alkaline soil.
- Choose a position in light shade. Polystichum can cope in sunnier spots where the soil remains reliably damp in summer but may suffer a few scorched fronds.
- When planting, allow sufficient space between plants for the fronds to arch outwards at maturity. You can check their anticipated spread on our individual product pages.
- Water-in after planting and keep hydrated when in growth, particularly during the first year.
Aftercare
- Most Polystichum are evergreen with new fronds emerging in spring. These persist throughout the year and remain intact throughout the winter providing attractive structural interest. The following spring the oldest fronds should be trimmed away to allow space for new emerging growth.
- Once established they need very little maintenance but will appreciate an autumn mulch of leaf mould. Avoid covering the crown of the plant as this may lead to rotting.
