Sow the seeds in any good seed compost including John Innes Seed Compost, giving each seed a good spacing of 2.5cm (1in).Before you sow, soak them for a few hours in luke warm water and then nick with a knife or scratch with sandpaper the seed coat, to further speed up germination.Two weeks before sowing remove the orange tufts from the seed and place in a plastic bag with a hand full of fresh compost.
The seed has a really thick coat and if you sow it without any preparation you could be waiting a long time.Strelitzias can be grown from seed, however, it does require a lot of patience. Apply a liquid feed, sold for using on houseplants, fortnightly. These plants require regular feeding during growing season (April until September in Britain). From the end of November the root zone should be allowed to become fairly dry between watering. They require regular watering during spring and summer to maintain constant moisture, without saturating the potting media this should be then gradually reduced during the autumn. Top dress containers, removing and replacing the top 5cm (2ins) of potting media, once a year and then re-pot about every second year or so, taking care not to overly damage the fleshy roots.Although any good potting medium should be suitable, loam based compost such as John Innes No 3 with added grit to improve the drainage are often easier to manage.They can be planted outside in a well-drained soil however they must be bought in before the frosts.Plants benefit from ventilation once the temperature reaches 20☌ (68☏) and above, or better still place them outside for the summer.They rarely perform well as houseplants, as the atmosphere tends to be too dry They also prefer a humid atmosphere, which is why they tend to thrive and flower well in conservatories and glasshouses.Strelitzia reginae is not hardy and requires a minimum winter night temperature of 10-12☌ (50-54☏).Malvern Autumn Show - 22–24 September 2023.RHS Garden Wisley Flower Show - 5–10 September 2023.RHS Garden Rosemoor Flower Show - 18–20 August 2023.RHS Garden Hyde Hall Flower Show - 2–6 August 2023.RHS Flower Show Tatton Park - 19–23 July 2023.RHS Hampton Court Palace Garden Festival - 4–9 July 2023.
