🌿 Bird of paradise

Use fertile, humus-rich, well-drained soil; loam or sandy loam amended with organic matter suits it well. Avoid waterlogged or compacted soils - good drainage is essential. In containers, use an aerated, draining potting soil (e.g. a quality compost mix cut with perlite/potato and/or coarse bark) that retains some moisture but doesn't get soggy; keep the substrate evenly moist during active growth and allow the top layer to dry slightly between waterings.

Bird of paradise (Strelitzia) seeds are slow and often uneven to germinate; the freshest seeds give the best results. If any are present, remove the orange aril completely, then lightly scarify the hard seed coat (a small nick or light sanding) to facilitate water absorption. Soak in hot water for 24 to 48 hours, refreshing the water if it cools. Sow indoors at any time (or in spring in warm climates). Use clean pots/trays and a sterile, free-draining medium (e.g. a coir/peat mix with added perlite or fine sand). Sow the seeds at a depth of around 1 to 2 cm, pack them down and water them to set. Maintain regular, but never soggy, humidity; high humidity is useful, but provide ventilation to prevent the seedlings from melting. Maintain constant temperatures, ideally 25-30°C (background heating is useful), with bright light (avoid midday sun on covered trays). Germination usually takes from 4 to 12 weeks, but can take several months. When the seedlings have several true leaves and the roots fill the container, carefully repot them in a rich but well-drained mixture. Grow in warm, bright locations, feeding lightly once established. Plant only when plants are well rooted and conditions are sufficiently warm (no cold nights); gradually acclimatize to outside sun and wind. Note: dividing established clumps is often faster and more reliable than using seeds to produce flowering plants.

Feed Bird of Paradise (Strelitzia) during active growth in spring and summer. For container plants, apply a balanced water-soluble fertilizer (e.g. 10-10-10 or similar) in half doses every 2 to 4 weeks, or use a granular controlled-release fertilizer at the label rate in spring and midsummer. For plants in the ground, spread compost and/or apply a balanced slow-release fertilizer in spring; a second light application in midsummer can promote growth and flowering. Reduce feeding in autumn and stop in winter when growth slows. Avoid over-fertilization (which can cause salt build-up and leaf burn, especially in pots); rinse containers occasionally with clean water and don't put fertilizer on the crown or rhizomes.

Apply a 5-8 cm layer of organic mulch (e.g. composted bark, leaf mold or well-decomposed compost) to the root zone to conserve moisture, moderate soil temperature and suppress weeds. Keep the mulch a few centimetres from the crown and stems to reduce the risk of rotting, especially in cool or damp conditions. Refresh or top-up mulch every year, and avoid piling mulch against the plant.

Prune Bird of Paradise (Strelitzia spp.) mainly to remove old, damaged or diseased shoots. Cut faded flower stems at the base as soon as flowering is over. Remove yellowed or tattered leaves by cutting the entire petiole as close as possible to the ground line or main stem; do not shorten healthy petioles to reduce height, as this weakens the plant and leaves unsightly stumps. If the clump is overcrowded, remove only the oldest outer leaves, keeping the new central ones. A thorough cleaning is best carried out in late winter or early spring (or just after the main flowering period), but dead or damaged elements can be removed at any time. Use sharp, disinfected tools and avoid tearing fibrous bases. For large clumps, it's best to divide them rather than prune them to control size.
