How to Grow Hosta
Perennial
Hostas are prized chiefly for their broad, textured leaves, which bring calm colour and structure to shaded places. There are compact forms for pots and dramatic varieties for borders, with leaves in green, blue, gold and variegated patterns. Summer flower stems also provide a useful accent above the foliage.
Planting
Plant hostas in spring or early autumn, choosing moisture-retentive but well-drained soil in light shade or dappled shade. Deep shade suits green-leaved sorts, while gold and variegated varieties often benefit from gentle morning sun. Dig in garden compost or leaf mould and space according to the eventual size, from 30 cm for miniatures to 1 m for large forms. Water thoroughly after planting and keep new plants evenly moist through dry weather.
Care
Water during dry spells, especially plants in pots, because hostas dislike drying out at the roots. Apply a spring mulch of organic matter, keeping it away from the crown. Slugs and snails are the main challenge: inspect regularly, hand-remove where practical, use barriers, and raise treasured varieties in pots. Remove yellowing leaves in autumn and divide overcrowded clumps in spring.
Bloom time
Hostas usually flower from June to August, with white, pale lavender or purple funnel-shaped blooms on upright stems. Flowering is often later in Scotland and cooler northern gardens. Some cultivars have noticeably fragrant flowers, especially in warm, sheltered positions.
Garden uses
Hostas excel beneath deciduous trees, beside shady paths and in woodland-style borders, where their leaves contrast beautifully with ferns, hardy geraniums and heucheras. Smaller varieties are excellent in containers near a doorway. Their foliage is useful for flower arrangements, and the blooms can attract bees and other pollinating insects.
Tips
Match the variety to the space, as some hostas become very large. Blue-leaved types retain their colour best out of hot afternoon sun. A pot raised slightly off the ground can help protect plants from slugs and snails. Seek AGM selections from the RHS or a local garden centre for reliable garden performance.
